Hardtail Racer Build - 85 ATC200S

[atctim]

As many of you know, last year a group of us raced "hardtail" ATC200, ATC200S, ATC185S machines at Pine Lake. We had such a blast. We had some basic guidelines to follow for the bikes we raced / built. Known as the SAS Class (short for Stock As trailprotrailprotrailprotrailpro), I can say it was one of the best times I have ever had on a track on 3 wheels. The guidelines are listed here:

Any hardtail 185, 185s, 200, 200s, 200m, 200 BR (god help you)
Must be semi auto
Stock frame
Stock engine (Freshen ups allowed if you feel its needed, not all 33 year old engines are mint and its understood)
No high comp pistons, cam, “clean up” porting none of that useless crap.
NO bolt on power mods
Unbolting items allowed, example: skidplates.
22 minimum front tire
18 minimum rear tire
Max of a +6 rear axle, anymore and your over the trike triangle anyways
This will keep us handling all the same or close to it
Any period correct STOCK part is allowed. For example, if a 81 atc 200 wanted front suspension from a 85 200s. Im cool with that. Keep it within reason. Atc 200 muffler on a 185s that kinda thing. Parts can be hard to find for your certain model and swapping may be needed.
Just keep in mind the IROC series of racing, stocker the better.
Gearing,
Please keep in mind that this is for fun, and it was just an idea a few of us came up with. We are not going to tear your trike apart, we don’t care. If you check out and pull away from the other 14 riders we will know you’re a cheater and a POS that can go camp with (Name Withheld but assumed).
General RPFLU machines will have….
Large honda H on front fender
Gold Rims
Sticker pack on rear fenders
Vented front numberplate
Stock fenders
And a "pete" name. Example. Slippery Pete or Peters dragging or sneaky pete
Keep the vintage look! Make it old school!
We plan on running ashtaboola in the spring for a test and tune. Trikefest and the actual ashtaboola in July so far. Maybe even the Hamlin PA race. This is going to be excellent racing and dirt cheap to do!

If this gets out of hand it'll just turn into a free for all then you might as well run open. We all can dump 3 g into a hardtail but this isn’t the point.

------------------------------------------------------------------------------------------------------------------------

And so the saga continues. 3 of us at this point have gone a step further as to build actual well modded out hardtails. We were all very surprised at just how well these little bikes actually handle on a TT / Flat track. And so here we go with another build. Here is what I am starting with. A Facebook Marketplace find just 30 minutes from my house (my favorite year and model too) a 1985 ATC200S. It's really looks pretty rough, but all the parts I will be using from it are the frame, the front end, and that's about it. I will update this thread as I continue to build this bike.

Here is what I started with. Note the signature Joe Dasher rear fenders.

Here I am all tore down to the frame

I was able to locate a new seat pad and seat foam from Ebay, and some new fiberglass fenders from Bryan Ditch.

247431

Next weekend a few of us will be getting together to modify the rear brakes. We are going from drum to disc. Here are my parts, ready for some fab work

247432

And here is a Big Al's (BAPP) case saver, which I never even knew was available for this bike.

247433

247434

I am also using a NASA +6" rear axle and TRX450R rear hubs to get this machine much wider than the stock 39" width. The new width is 48" with axle and hubs + 3/5 offset wheels. I have found a bunch of 4/4 aluminum front wheels for these machines too, so they will have aluminum wheels all around. Bye bye rusty heavy steel wheels. Hello powder coated aluminum wheels. Seen here is what they look like prior to PC.

Subbed. Love a souped up hard tail. Hope the SAS class holds true for next year as I have one Im planning to drag out.

[RUNMEDOWN]

Love the idea and the builds. Hope to see a lot of pics on the next run.

[schlepp29]

I'd like to get mine done this winter and race ashtabula with you guys

[jays375]

Hmm.I see some cheaters coming out to this one.lol

[bkm]

Very cool guys. Keep it either stock or oem 200x parts if you're going to hop them up. Love the mostly stock race classes.

What is the history behind the name "Pete" for the trikes? Sorry if I missed something from the past.

I was 200s, before 200s was cool. https://uploads.tapatalk-cdn.com/20171104/55cc5738c665df701e41f9bf7b89a23b.jpg

So, does a 185 chassis have to run the 185 engine or can a guy swap in the 200s engine. Asking for a friend of course.

[Scootertrash]

What's with the upside down grab bars in the OP pics?

[bkm]

What's with the upside down grab bars in the OP pics?

The reasoning I've heard about the flipped grab bar is a racer back in the day had a bike land on him and the grab bar broke his back, so then the racers started flipping them or taking them off all together.

[86T3]

Class rules, flip the grab bar. Like a real a-hole. This is a fun group to race with, we rrally had a blast with these last year. Getting more out would be incredible.

1. Acts as a rear bumper if someone tries to ram you.
2. Lower "handle" makes it easier to lift higher and load into truck bed unassisted.
3. Best reason: Safety. Acts as a guard to help keep other riders body parts out of your chain in the event of a mishap.**
4. Makes you look like a real a-hole

** Did anyone else see Tanner and Mac get tangled up in turn 1 at Ashtabooola 2 years ago? Tanners grab bar kept Mac's arm out of his chain.

It will. All the guys doing Super Mod Pro Unlimited Hardtail have a second race trike for this purpose. I think everyone is keeping their original Pete racer Stock as Excrement (SAS).

[keister]

Very cool. :)

There was a guy Kintore used to work. No matter what he did wrong, he never got in trouble or got fired. Nothing ever stuck to him, so they started calling him Slippery Pete. It just took off from there.

Without mentioning any names, someone actually signed up their hardtail at Nationals under the name Peter Beiter. Hilarious over the track PA system loudspeaker and radio broadcast!!

[atctim]

Over the weekend we successfully upgraded two race hardtails and one trail hardtail to disc brakes. The conversion takes roughly 2 - 3 hours. Much cutting and grinding and fitting and welding is necessary for this conversion. A big thanks to Kintore for getting this off the ground and doing his homework on this awesome upgrade and doing the lion's share of the work on my conversion. I do believe Monk Cox is to thank as well as he showed Kintore the ropes. We used TRX400EX rear brake calipers and mounting plates, and left hand master cylinders / brake lever, deleting the foot pedal all together. These pictures are not great, but will give you an idea of what is needed and how we did it.
I'll take some pictures of it on the bike this evening and get them uploaded in the morning for a better look. We did test run one and the upgrade proves to be very effective over the old worn out drum brakes.

Reasons for upgrade: better performance, weight savings by ditching the heavy drum,shoes, cover, pedal, and pedal mount. I can't say exactly how much weight was lost, but I am guessing in the 1 - 3 pound range. When the build is complete, we will have it weighed to see final weight savings, but our SAS bikes dropped almost 30 pounds fom stock, and these will prove to be even lighter. I am shooting for a 250 pound final weight. Another good reason is safety. The drums wear out on these machines, and go out of spec. to the point where even with new shoes and cables, the shoes can not open far enough to give you the braking power needed. This is a wonderful project for the backyard mechanic and shadetree hacks.

What's needed for Disc Brake Conversion:
Parts - 200X rear brake hub and disc, left hand master cylinder, 66" long brake line, 400EX caliper and mounting (backing) plate (we all used Chinese cheap ones $20 on ebay)
Material - axle spacer made with same ID as axle OD, thick walled tube for caliper mounting bolts, small pieces of scrap steel for welding in straps for strength members
Tools - 4 1/2" grinder with cut off wheels, welder, buffer, grinder
PPE - welding gloves, grinding face shield, safety glasses, long sleeves, ear plugs

Approx time to convert - 3 hours.

[schlepp29]

All right! Thanks Tim. Still looking for rims so I can run the stock class with you guys

I am having the stock size 200S / 185S wheels made of aluminum. They are really best used up front only, as you want 5/3 offset for the rear for extra spacing. I already sold out of one batch, but there is another batch coming soon. Looking at Christmas time as it stands, but you know how backorders work, so it could be longer.

[atctim]

Small update. While I wait for PC parts to come back, and I have all other hard parts cleaned, polished, sorted, I thought I would share my small collection of Big Al's NOS parts I plan on using. I've been collecting Big Al's 185/200 parts for not very long, but I think they will be my new go to on Hardtail goodness. A little picture to tease you all with.

[xrider]

Love some old school BAPP parts. You need a set of their Grab-on grips, they scream 80s

Hay those parts where in my garage ! Thank u .

[atctim]

I am still waiting on my PC'ed parts to come back - I'm getting anxious as you can see. Hopefully next week sometime I'll have them back and can actually start assembly. For now here is a sneak peak of my color scheme. Don't mind the blocked out motor parts nor the wrong frame. Just something to hold up my bodywork. I am really liking the colors of this bike. Makes it look so very "Vintage" and "Racey". More to come soon.........................

Happy New Year all!

As I am waiting on my parts from PC, which is taking way longer than what I expected, by like a month over, I decided I needed to build another quick project. It is almost done, and just in time for my parts to be back to get back on track with the original build of this thread. I basically threw this together with stuff I had laying around. Should be a fun pit bike and a really fun one for kids to ride on. This will also explain what I hid in the above picture I posted. Was mocking up the motor in an 83 ATC200 frame. This is an 85 ATC200S with a 16HP 65cc liquid cooled 2-stroke engine. Stock for stock - it should be about 25% more power and at least 25% less weight, probably more.

[atctim]

well well well, I finally got my PC parts back. They all look great. Most parts are flat black, like the frame, pegs, mounts, save for a few accent pieces. The rear carrier is red (to simulate a red rear shock - lqtm) and the triples and bars are gold. If all goes well I can get it rolling this week. These pictures are very random I realize, but just to give an idea of how they turned out. More pics to come as the parts all come together. If I haven't yet mentioned it, I am doing this bike in the identical colors as my 2017 Africa Twin. Every part should be the same color as on the bike. The bike aesthetically is so very pleasing to me, and I assume the trike will be the same.

[86T3]

This is going to be awesome Tim, i can't wait to see the finished product

[Bernard3rd]

Looks great!

[atctim]

I got very little done last night, but very little is better than none. But first - I weighed the 2-stroke 200S last night. A stock 1985 ATC200S weighs 278 pounds. I got the weight down to 206 pounds. That is a weight loss of 72 pounds. I feel excellent about that. It is a 25.89% weight reduction!

Here are a few pictures to keep this thread moving. First is a comparison of my Africa Twin handle bars, as compared to my new race bike handle bars. Second is a little bit done last night. pressed bearings and seals into rear carrier, installed NASA +6" rear alxe with TRX450R hubs, and installed an NOS OEM rear grab bar. More detail to come as this build continues. Thanks for looking.

BTW - The frame looks dull because it is flat black. The Africa Twin has a flat black frame. Looking at it in this stage makes me wish I would have done gloss black, but I feel confident in Honda's design team that the flat black will pull it together as the build progresses.

I'm going to put the weezy stamp of approval on this scheme buddy!

[MRSOUND]

Love this! But why no love for team green? ahem, KLT!?? 200's are ruled out because they are not auto?... But it would still be SOS. 185 & 160 are shaft drive... allowed? This a very race-ist class! (see what I did there) I'm too afeared to race anyway (old and fragile) and just wanted to subscribe to the thread and figured I'd have a little fun with it! Looking awesome and looking forward to seeing more!

The original idea was that everyone in the class would be on identical bikes with identical HP and identical handling characteristics. Remember the IROC races? Everybody had the same car (just a different color). So it was an exactly level playing field. A shaft drive clutch machine is quite a departure.

[atctim]

We finally finished them up over the Easter weekend. They look excellent and run even better. I will not go into all the motor details as they are proprietary information, but let's just say WOW!

Also - the turning radius is out of this world on these bikes. The 2018 NEEDT race season is upon us and we are ready to rock in the Open Ameteur class on these little units. I mean come one, they are just ATC185/200 hardtails. Just little utility machines...............

[atctim]

Also - it should be noted we pulled roughly 40 pounds off of the stock bikes. Final weights (wet: full tank of gas and full of oil)

Tim's 200S = 248 Pounds
Josh's 185S = 243 pounds

These are the true "Ultra-Lights" Bikes we had hoped for. Add huge HP gains and we have a couple of real cool little bikes that are race ready save for the Chiropractor!

[schlepp29]

Wow! I'm impressed! Looking great

Very nice modifications. The bike is great. Thanks Ironchop for turning me on to this thread (I need to get better at searching). Hopefully, you won't mind a few questions? Is the brake line ready made or did you have it built? Is the left side master cylinder a cheapo unit too or is it oem? Parts sources??
Thanks!!!

[Kintore]

I can help here with the brake line and parts.
I have used both a left hand Chinese master from eBay as it's on my trail bike. My race bike is a kfx90 lever.
Here is the Chinese master...

https://m.ebay.com/itm/Brake-Master-Cylinder-with-Lever-Left-Side-ATV-Quad-4-Wheeler-50-70-90-110-125/232204396878?hash=item361075e94e:g:4p4AAOSw42JZKMD G

The brake line is as follows. 65 inches long.
One end is a 15 degree. The other is a 90 degree. With a 45 degree offset to each other. Custom made from apex brake lines from a guy named Raymond Chan on Facebook. He does lots of custom work and done 8 or 9 brake lines just for this conversion.
It's a 200x disc and hub
400ex caliper WITH mounting plate
You need to make a axle spacer roughly 3/4 long. Or die grind out 2 axle oem locknuts and they will work
A made two bolt holder spacers to weld to oem.carrier

[Cow Pie]

Thanks for the reply Kintore. Awesome story on the Pete naming convention, I used to work with a guy like that. Pardon me for a few more questions:
1) Good info on the brake line, problem is I don't "do" the Facebook thing. Does he have a website, email, #?
2) Why did you not go with the standard master cylinder off of the right foot pedal? Was it a weight savings issue?
3) When you guys powder coat a frame, how do you keep the rubber coating on the wire harness clips that are welded to the frame from melting off? 251487
4) Thanks!!!

[atctim]

#1 Here is the website - I recognized the logo right away. Contact him through here: http://www.apexbrakes.com/products.asp#

#2 Weight savings and we talked a lot and both agreed when you are used to a left hand cable brake, you get used to it - so no need for the foot brake. I think I ended up cutting about 3 pounds of extra weight off my frame. The foot brake stud and cable mount was about 6 or 8 ozs if I remember correctly.

#3 My PC guy never said anything about the rubber coating, but it appears he just PCed over it.

#4 You are very welcome - keep the questions coming. More than happy to help out.

[daddy420big]

i been following this build on here and on facebook you did a bad ass job man i need to do this to one of my hardtails to and you guys should build a mx 185s or 200s

[Tri-Z 250]

Tim I ended up getting a low hr 85' 110 for my son. The 185-200 jump from 70 and Zingers was too much size. I still want him progressing in hardtail FT so the 110 is a good medium. Plans are to mimic some thing you guys have done for setup. Your gearing? Just a direction to head as I'm not the same cc. Front rims, any word on the second go around? Going to change out hubs for some width as you mentioned in the rear. This is a great class, you guys really set the bar. Motor wise everyone's on level ground which helps keep the field competitive. 110cc Jr class anyone? Lol could catch on

[atctim]

Hey Steve! A 110 could be done, and done awesomely, and a few guys on here, like Shortline as well as a few others have done the same to 110s, and really know their stuff! I have front wheels available - email me at tkeister@gmail.com for one. They are $100 + shipping - will bolt right up to your 110 front end. I like the idea of SAS 110 class for the juniors out there. Not sure on gearing a 110 - at least up front. PBI makes rears for the 85110 in 31T to 60T. That's a lot of options. I'm not sure what stock gearing on an 85 110 is, but for reference (remember smaller rear tires change things much) my SAS 200S is running 13/35, from 11/43 stock. It will be fun to see the spin offs this class may create. I'll be looking for an email from you.

[Macs]

Dang Tim. That turned out awesome!!!!!

[Cow Pie]

What is the reason for the caliper to be at 270 degrees on the disc? Is it function or aesthetics?
Thanks Tim!

[atctim]

Thanks Tim!

Strictly a function thing. It's the only place it can sit and not interfere with either the frame of the bike or the ground.

[Cow Pie]

Excellent! I have received most of the parts to complete this. Missing the tubing and the flange bolts to mount the caliper. Are the mount tubing and bolts that length for strength, such as more surface area available to weld up to the original backing plate? Are the bolts standard or hardened? Thanks for the answers.

[Kintore]

We just used standard Honda bolts we had kicking around in the shop.

The tubes or holders we weld to the carrier were just peices of sch 80 1/4 pipe. You could get spacers made up at a machine shop.

[MrConcdid]

I have been thinking about building one of these myself, thanks for the information.

Q. What color gold paint is this?
Is it spray paint?

I have been frustrated as of late with the performance of the stock brakes on my 200S, this is a perfect solution!

Am I correct in assuming the stock 200S rear axle will work with the 200X hub and caliper?

That's what I understand...though some spacers may need to be made to clearance the carrier depending how you do it. I'm planning on doing this to my 200M....sometime lol

Tools - 4 1/2" grinder with cut off wheels, welder, buffer, grinder
PPE - welding gloves, grinding face shield, safety glasses, long sleeves, ear plugs

I'm going to start aquireing the parts needed:naughty:

[ps2fixer]

Not to spam up the thread, but I just happen to have a Race style Harness I made for a customer then they changed their mind on what they wanted.

82-83 ATC185S or ATC200

81 used a different engine connector
84+ the harness got longer, I think the coil connectors changed this year too.

FYI, race style harness just means all lighting related wiring is removed, left handle bar controls are not wired, you get just the wiring for the tether/kill switch since there's nothing for lights. I include pig tails to splice onto the kill switch/tether of your choice so nice and plug and play type of setup. Harness layout is for stock mounting points for the different parts (CDI, Coil etc).

What's pbi I'm looking for some rear sprocket for my 200 s Honda where do you race and where can I get the specs to build one for racing I would need ther tool sheet for the sad 200 class

Here's the link for pbi. Even though they're on the other side of the country you'll have your sprockets in 2 days. Pbisprockets.com the rules are pretty simple, you have to keep your machine stock except you can widen the rear end and run an 18" tire in the rear. You can get decal kits and numbers from Bruce Alleman @ Blueline decals, number plates from Liway Swinehart. We race at the Pine Lake NEEDT races, this year they were in July and September. Are you on facebook?

Are vintage after market exhausts allowed since they were from that time period and you could get them the same day as your 3 wheeler

Absolutely not!
The idea is not to keep them vintage or period correct. The main point is they are all STOCK.

Good question. Thanks for asking.
