ATC 200sx

[Jmoozy27]

With a little help from some 3ww members, and the drive to build something awesome, I find myself knee deep in a build. The donor is a '88 200sx quad. Quite a rare find as it is the last year of the four wheeled sx. As ol' deuce was wrapping up his super X build I stumbled upon the donor while in search of a new prospect for my next project. 2 comments from the super x thread would not leave my mind:

1. The hardest part was finding a donor. (One was sitting in front of me)
2. Quads make awesome parts bikes. (That's about all they are good for)

So I traded my BR parts machine (which I no longer needed) and $50 and the rest is history...

All the motor needed was a ring job. So I went .20 over 10.25:1 wiseco. Stock 200x exhaust (from dirtwheels). I ordered the wrong gasket set so I am waiting on it to assemble motor and put it in the frame. Put a new timing did timing chain, new clutch plates since I had the cover off. The oil pump chain seemed loose but after researching it is common so we will see. The inside of the motor was very clean so I was glad to see that. Cannot wait to get this machine running. I forgot to mention that this is my first build from frame up. A couple more pics what the hell.

Cool to see another second gen build. When opportunity is staring you in the face (aka donor quad sitting in front of you), you gotta take it. keep up the good work

[Jmoozy27]

Yes sir, I wasn't even planning this build it just kind of snuck up on me and I rolled with it. Had to put a couple other ideas on the back burner. I keep telling myself, 1 at a time, otherwise I will screw them all up.

[Jmoozy27]

She's a roller, kinda, I just put on a few tires I had lying around and a Chinese shock that would bottom out with my 4 year old daughter on it. I just wanted to see what it would look like with wheels on. I will likely get a new front tire when Its all said and done and I have a decent pair of ohtsu' s that I plan on using for the rear. I love how the 2nd gen 250r axle widens the stance. I also used the quad hubs because they seemed solid and added about an inch of total width to the axle.

Dang it! All of you guys and your build threads... I'll never get 1k security blanket in the bank with all this inspirational material to read...

[Dirtcrasher]

Is the thin metal cover over that oil pump gear? Thats what keeps it on......They'll may also be meant to keep some oil in a bath there, I'd have to look at one again....

People take them apart and throw them away.

Best of luck, your getting there!!

Thanks, I never throw anything away. I'll use it some day right... Yes the cover was installed, just not it the pic. I'm pretty sure it was an old post of yours that I read that made me stop worrying about that chain. I couldn't find one for the life of me. A lot of sites show it as being available and even let you order and pay for it only to break the bad news 3 days later that your money has been refunded.

[Jmoozy27]

Got the stock 200x exhaust mounted. Put the carb on but there isn't much room for an intake boot. I may need to find a new intake manifold that isn't as long.

Just got some 1st edition delrin swingarm bushings from bkm. Sort of a prototype for the 200x swingers. These things are nicely designed and seem to be a perfect fit.

I started cleaning up the plastic. The amount of grime on these was enormous. In the first pic you can see where the factory honda sticker was before I tore it off. My goal is to make all of the plastic look like that. Definitely have my work cut out for me.

'86 frame, '84 swinger, '86 shock:lol:

Surely this will cause a problem...:naughty:

213395 213399 213400

I think I found a solution... I still need to fine tune everything but fitment should be solid. Bottom mount will need to thickened at the brackets and extra gussets will be added for strength and reinforcement. Should make for an awesome ride though.

[oscarmayer]

lookin great sir!

[Jmoozy27]

Prepping the swinger for modifications. It seems to be fairly simple modification. Remove the necessary metal to allow free motion for the longer shock to mount to the lower bracket. Then add some reinforcement. I will likely use 1/4" steel plate. Any advice from the many metal specialists is welcome.

[Ol Deuce]

When is the "D" Day??????????????

[Jmoozy27]

It's hard to tell I still need a few odds and ends. I have decided which fenders to use. I really don't want to go with the 2nd gen plastic. I would rather something ONE but converted from another trike. I still may use the 200 quad fenders. There is just so much to choose from. I may even implement the quad rack just to give it some utility flare. There is such a fine line between quality and cost. I also am waiting on the tank to get brazed and coated. Dropped it off last week and the guy gave me about a month timeline. I wish I knew someone who repaired metal tanks. I just know this prick is going to charge me out the asss.

[Jmoozy27]

It's good to be back on 3 wheels

213752

I have also been entertaining some headlight and fender options

213753

[Jmoozy27]

Figured I would update this build as I have been very busy at work and I just need to tie a few loose ends. One of the main things is fenders. They are so expensive. I really would like something new but I feel that everything that maier produces looks good but doesn't seem reliable. How hard is it to fit 83-85 200x fenders or 81-84 250r fenders? Also waiting on the take to be repaired and redkoted. I got a quart for $30 at o' Reilly which seemed cheap to me. I also acquired a complete rear end off of an 84 200x from a friend for $100. He's got a really nice set of rear fenders that I want but I don't know if they will fit. My shop is a complete mess due to time constraints an inability to clean up after working. I will update as more steps get completed. I'm ready to wheelie this biitchh!!!!

214436 214437

[Ol Deuce]

I would try 2nd gen R rear fenders or the 200x should be easy to do !!! you may nee to change the rear spacing on the mount! 214614

[Jmoozy27]

I think that is the route I am going to take. I should be able to get one or the other locally. The 200x may be the easiest to acquire but you never know.

[Jmoozy27]

Converted the quad seat to fit the 200x pan
214816

Installed the rear brake, used a 60" Chinese brake line w/ $15 left handed master cylinder. I've said this before, they are a biitchh to bleed, but when you get it you got it!!!
214819 214820

[Jmoozy27]

I grabbed some 1st gen OEM fenders locally for $100. Andy's ATC always hooks me up and gives me 1st pick at a discounted price. Just waiting on the tank to get brazed and coated and she will be sparked and burning. :acr

A few pics of the 1st/2nd gen seat/fender conversion:

215359 215360 215361

By no means is it bolt on but with some measuring-cutting-drilling and patience turns out that it isn't too hard. Although the seat pan fit isn't perfect. It's good enough for me.

215362

Had to sacrifice 30 yr old ohtsus for I'm guessing 25 yr old ohtsus. These old tires are a biitchh to unseat and just as hard to get the new ones on.:lock:

3 strikes and your out!!!

215483 Looks like I'm gonna have to get new tires.

I tried and tried to salvage sole history but it looks like we are gonna have to go with whatever bike bandit has to offer. An hour ago I was chugging beer and throwing tools. I'm over it now. Gotta clean up and roll on.

With that being said. Any recommendation on some solid tires for 200x rims front and back? I don't really know what it's out there.

[86125m]

I would put dura nobbies on the back. And a kenda front max on the front.

[Jmoozy27]

Definitely the best bang for my buck. I will order them today.

[Jmoozy27]

Well I didn't go with the Duros, instead I'm gonna give the wanda knobbies a shot. The price was legit and I haven't heard anything negative about them. I got one on the trike now and I like the way they look. The ohtsu that's on the other rim is continuing to give me a run for my money. I got a kenda max for the front. Still waiting on the tank but I have another tank that I can use to break the motor in. Hoping to let it eat this weekend. Although, that is yet to be seen.

[Jmoozy27]

There is nothing like a fresh pair of boots!!!:lock::beertrailpro

[Jmoozy27]

She got fire tonight, still waiting on the tank though. May use another tank tomorrow just to hear the motor. Also need to figure some way to tension the chain. Maybe some type of idler pulley system. I tried to install a 24mm stock 200x carb but the bowl was too big due to the electric starter. So I changed the bowl and main jet to the 100 out of my 200s carb so that may work. The stock main for the quad was a 98. We will see, I don't think it will be too far off.

[atc300r]

I made this chain tensioner from lawnmower parts and a skateboard wheel.I also made one for my 84 200x. I will post pics of that one later.215916 215917

She fired up tonight!!!:w00t: Its so quiet with the 200x exhaust. Jetting should be fun. I may need to order like 30 jets. I figured it would be fun. That's why we experiment right. What do you guys think of the color scheme. Figured I would bring it back to the gap.hammer:crazy:

[YTZ drew]

Yamaha sky blue. Nice!

[Jmoozy27]

Yeah, it off of an 88 dt50lc that I picked up a few months back. It's been put on the backburner, amongst others. I'm just using the tank to break in this motor. I haven't heard from the radiator shop that is repairing my tank. He did say that it would take a while, but I'm anxious to get it back. Even more so now that the motor is running.

[atc300r]

Couple pics of my 200x chain tensioner. Next week I will pull it off and get better pics. Sorry for the mud I haven't had a chance to take it to the carwash. The one in town closed. 215986 215987

Nice!!! Is it welded to the swinger? Or is it bolted? I may go to a local lawnmower shop and see what they have in stock.

[atc300r]

I bolted an offset 2 holed bracket to the bottom shock link bolt.I used a lawnmower wheel bolt threw the aluminum L shaped bracket wich is from an old lawnmower. I bolted the skateboard wheel in the other hole and put a spring on it. When I take it off I will lay out the parts and take some good pics.Both of my chain tensioners have held up well. Iv drag raced,MX practiced ,flat track raced and trail rode both trikes several times.

[Jmoozy27]

I picked a plastic 200s tank for cheap and with some mods the fit is decent. It's a good backup until the oem tank is done and I dont think it looks that bad.

216038 216039 216040

Now the only thing stopping the ride report is the chain. I will try to figure something out this weekend. It doesn't look too hard. I was able to get the jetting pretty close. 24mm keihin 200x carb (yaegerb) with the 200s bowl to clear the starter, slot style #105 main, #38 pilot, needle on 4th slot from the top. Also fitted an air box from something maybe the quad w/ a uni filter. It's hard to know yet if the adjustment is right but there is no sputtering or bogging with no load. Once the motor is broke in I will do a couple of plug chops. Anxious anxious anxious!!!!

Baby's first trip out of the crib, followed by the first steps. All I can say is that it's rides like a dream. The suspension is solid and the motor is smooth. It's hard to believe that just a few short months ago it was just a frame hanging in my shop and a thought in my mind.

[dirtwheels]

Hey, nice job! Its looking good!

[Jmoozy27]

216170 216171 216172

This thing is so much fun!!! I feel like I am 8 yrs old again on my old 110. It's bringing me back. It rides so good, just effortless. I strongly advise anyone who is looking for a purposeful build to take on one of these. After finding a frame and motor the options are endless and the results are plentiful.

[Ol Deuce]

Kinda Cool Ha !!!!!!!:Bounce:Bounce:Bounce:Bounce:Bounce The same but different! Great Build !!! How do ya like the ride!! and Reverse :drool::drool::drool::D Ol Deuce

[Jmoozy27]

It's really like nothing I have ever rode. I'm still working on some jetting and clearance issues with the carb. I did successfully install a drive chain tensioner. It's an old roller skate wheel. Told y'all I was taking it back to the gap.

I did a cut hose down & back to get the air filter on ! Things are really tight with the carb!!

[Jmoozy27]

I actually am running what I think is the quad airbox with no lid and a cut radiator hose. I will get some pics tomorrow.

216280216281
It did ok in the end!!

That looks sharp. Over here almost have to run some type of an airbox. There is so much rain year-round that puddles are everywhere. The most I will do is pull the lid off.

I went up a tooth on the countershaft today. Now it's 13x42 and it shows. I love this little machine. Good speed and power for such small displacement. Makes me wonder what machines of today would be like if they were still being made. But the. I think about what it would be like if everyone had one. I probably would have taken up another hobby.

Fog it, I went up to a 110 main. Oddly enough it's the factory jetting for stock 1986 200x. It just goes to show how corked up quads were even in the early stages.

216564 216565 216566

I have been doing a shite load of riding around the house. Mainly at a 30 acre plainy park at the end of my block. Some of the last untouched land in the town where I am from. I plan on riding there until told otherwise. It's got a lot of old trails along with a few bump that I have been catching air on.(probably like 4-6 inches:wondering) Although it feels like I'm smashing doubles with ease. Bringing out the kid in this man!!!! :lock::w00t:

[Jmoozy27]

Did a little bit more tuning on the super X, I drilled a couple holes in the baffle and grinded the weld in the header. It gave it some extra grunt and allowed me to go up to a 115 main jet. This thing is so easy to tune. It keeps getting better and better.

[Jmoozy27]

Also picked up an '86 200x parts trike. Not complete by any means but has a lot of good parts including a painted tank that does not leak. It is currently full of apple cider vinegar to get the rust out.

[big specht]

Do you know what that air box is off of? I'm collecting parts to do one of these conversions some day.

[Jmoozy27]

I think it is from the sx quad. It wasn't on the parts bike initially. I got the air box from the previous owner when the build was near complete. It's a tight squeeze so you have to run no lid. No boot to the frame, not enough room. I'll post a couple of pics later today.

[Jmoozy27]

I used a flexible radiator hose as an intake boot. Uni pod filter, and I used plumbers plugs to seal the breather hole and drain hole until I find the proper hose to fit.

Nice!!! I like the ductape. Great start... when your ready, if you'd like i have the front right motor mount template i'll send it to you. When you have the two fronts/spacers and top mounts bolted up--(motor in place) where to put the rear mounts will be staring at you. Just take your time it'll all fall into place. Congrats!!!
Oh and paint the frame LAST after everything else....and get some lighter rear tires....

Thanks Shep, I'll certainly take you up on the motor mount template! Yeah this 200X was literally bought just for the frame. Everything else in it needs lots of attention....
