86 200s wants to go fast

[86200s]

I have a 86 200s that i just finished rebuilding the top end i over bored it .20 over with a 10:?? something piston, custom exhaust system load as hell fire spitting monster with 200x front end (made them fit). Runs on high test with octane booster. its not the best engine to trick out but its what i got. im getting a 200x carb. Does anyone have any ideas or know where i can get performance parts for it. It has or i think it has weak spark i just want it to be as fast as i can make it. oh and it got a 13 tooth front it hits 60 mph. And im looking for a smaller back sproket i got a 43 right now and i need some good heavy duty clutch discs cause it slips right now but there really old :TrikesOwn

[83185s]

dude it hits 60!! thats bad ass! my 185 only did 50 barely..that was on a good day! howd u get it to go that fast? trailprotrailpro front sprocket prolly..13 mines 11 to 41 ratio sprockets...im puttin a 200x head on mine. gettin it bored 20 over and gettin the valves switched from my 185 to the 200x head since the 200 doesnt have any in it..other than that it should run fairly good and maybe hit 55 lol

[86200s]

i have the 13 tooth front 43 baq it pulls hard all the way even though the clutch is slipping quite a bit i getting ready to replace the clutch discs. im lookin for a smaller baq
sproket i want it to hit 90 when im done not safe or realistic but that would be bad ass. it has plenty of power it has enough to hit 90 but not the ratios

[Dammit!]

i want it to hit 90 when im done

I dub thee, Bouncing Death. :D

I'd like to see some pictures of this "death machine". You should look into getting Barnett clutches as your next mod. I recently added these to my 200s and they were a huge improvement over my "still-reasonable-good" clutch. They'll be killer if yours is slipping bad already.

Also, I added a xr200 cam. Honda put our motor on a dirtbike and they used a hotter cam in it. This cam gave my trike WAY more power. You should try and get one off of ebay. After you get the cam, the install in only a couple of hours and very straight forward.

Good luck with your unrealistic goals. I guess even if you don't get there but make it close you're still going way fast.

Oh, do you not care about taking off fast???

Grab you some new clutches soon!

I read you're running premium AND octane boost.

These guys run these motors in bikes and get 185's with 24hp with speeds of around 100mph!

They do things like:
run CRF150 pistons (high rev piston making 185cc)
custom cam grinds (one class is restricted to factory cams so they run XR200 cams but only the first model is any good)
Cam bearings (lower friction)
megaphone exhausts (some run just a header pipe NO MUFFLER!)
external oil coolers
28-33mm sized bore on carburettors
modified combustion chaimber to give higher compression.

With the clutch, to stop it slipping, alls you need to do is put heavy duty springs in the clutch and standard plates will grip (providing they are in good condition). You can buy these at any good aftermarket sales store or you can get them from other motors from the wreckers (like out of a 250 kawasaki or something). Just take one along and find one that looks similar but is slightly longer or has thicker windings. I have also heard that the small valve spring from these 185/200 honda motors work but dont quote me.

The list goes on!

I heard that a wilder cam would wear out the cylinder head wear the cam rides and the head would only last for like 6 months were can i get that Barnett clutch trailprotrailpro talking bout. Thanks for the help Ill have some pics soon

Just do an internet search for the clutches. My local ATV shop had them in stock.

You would have zero reliability issues with an XR cam. The lobes are not aggressive enough to require a spring with a high, high seat pressure. If this was necessary then you'd have reliability issues, but the XR cam is a *STOCK* cam for the honda 200cc line of motors. It just wasn't stock in our trikes. There are countless 20-year-old XR200's running around that have lasted longer than "6 months".

As for the head becoming worn where the cam rides, this makes zero sense to me. The cam approaches speeds of 18,000 RPM, but your new cam will be spinning the EXACT same speed as the one it would replace, that is 2X your motor speed.

Again, I don't think you can go wrong with the XR cam.

Thanks im on the search for parts :D

i have to run turbo blue race fuel in my 250r if i dont have enough octand it pings really bad when i crack the throatel all the way and it has 3 base gaskets on it??

Dude you got it backwards, the cam spins at half engine speed not twice engine speed!

Also, if you have something that has a little more torque than standard you really need the heavy duty clutch springs. Make sure you ask about them, it will fix it forever.
I also agree about the XR cam for you. Its more reliable and its stock for a Honda 185/200 motor.

Thanks for correcting me. I don't know what I was thinking. You are absolutely right.

No kidding, they could make a metal song about it! To turn at that speed on that thing youll have to be hanging 1" off the ground from 1 peg! But hey I'm all about complete insanity, thats why I'm building the first heavy modified big red that still uses the 200cc bottom end. :D :D Pics to come hehe!

i hear the heavy duty clutch spings for the 185's 200's dont make a diffrence

[HaggLE]

My only experience is with manual clutches, I wonder if the auto clutches behave differently...

If you think about it, those 4 springs are what force the clutch plates together. The harder they push the more grip the clutch has.

You heard right. Aftermarket clutch disks and heavy duty springs are a total waste of money on a manual shift auto clutch model. Most of those running today still have the original disks. If its slipping, replace the stupid disks, and drive it for another 20 years. It has nothing to do with performance. Only the centrifugal clutch can alter at what rpms it engages.

[Xtreme_415]

my 200S clutch was slipping badly, i shimmed the springs with washers and now it does'nt slip....oh, and this guy i know took an XL 500 dirtbike, put a 200x front end and a modified 200X swingarm, and turned it into a trike....the fastest thing ive ever ridden in my life

[short4stuff]

nice lol .. my friend has one too, but I believe it has 250r forks and a swingarm .. its intense.

[threewheelin-feelin]

i dont think i would want to go that fast on a bike with no rear suspension..... but that is still cool :TrikesOwn :w00t:

[honda200]

heres some gear sugestions

run a 14 on the front

run a 38 on the back (yes, a 38, it should be available)

if you cant get a 14, stick with the 13

also, what you can do, is get a carb off a honda bike, 250 or 350, and port out the intake to fit the carb, once you do that, get it on there, port the exhaust too, trust me, its makes a difference!!

you can also add a big bore kit, 200S is a 5 speed, correct? if its possible, add a 1986 200x bottom end, bam, you gotta 6 speed manual clutch!!

[83185s]

that would be one bad machine but man if i was u id get a suspended frame.. 50 is bad enough on the roads with no suspension..i cant imagine doin 90...well i can but i dont want too..lol...im sellin the 185 and gettin a good 200x pretty soon so ill have a good trike for once..im tired of dealing with anything that has an s on the end...lol

[HaggLE]

Back in the 80's my father had a 185 for racing. Decided that you cant go fast without suspension... SO HE MADE IT HAVE IT! Thats right, he hand made triple clamps and swing arm and put suspension on a 185 trike! Aussie ingenuity at its best.

Oh yeah, IT WAS FAST!

[bebeav]

i'm in the process of rebuilding my '84 200es engine.
I'm going to run a 10.25:1 Wiseco piston, XR200 cam, XR200 Carb, XR200 header with cobra silencer, Homemade P&P and Uni Filter. i hope to put at least 22-23hp.

i'll give you some news when it will be done to give you feedback about performance.
