Why wont my 200x wheelie and why does it smoke???

**hawaiirider** · 07-08-2013, 07:55 PM

just rebuilt my 200x motor - actually its a 200e wedged in a x chasis. new wiseco piston, all new gaskets, had shop regrind and install new valve seals but it smokes pretty decent?? has lots of compression on the pull handle and runs great it does have a race cam in it.

also it has a custom built 1' longer swingarm on it, the shock is a less of an angle than the stock mount. it was a wheelie machine, but now it just does not want to wheelie?

If it smokes, something wasn't installed/machined correctly. Did you have the cylinder bored over, and machined properly for the new piston?

So if I understand your "english" correctly, it used to wheelie with that swing arm, but now it does not?

Hello

Did you have it bored out?

Ig not did you havbe the piston clearance measured?

Did you have the bore measured for taper and out of round?

If so what was it?

Did you put a cross hatch pattern on the bore with a 3 blade hone?

What color is the smoke, lite blue/gray or very dark to black?

How does it idle?

What is the mfg and model of cam or specs from cam card?

Did you do a compression test or leakdown test? I know someone will say it.

WONT WHEELIE

Did it have swing arm on it before?

What performance upgrades did enge have prior to rebuild?

Is this cam more of a top end cam than previous one?

Did you rejet for new cam?

If cam has more top end you need to gear it lower, you also lost a little compression because intake valve is most likely closing at a later time.

I know that the prev people have asked a lot of questions, but a few more
How well do you know the shop? They may not have put something together right since its an older engine.
There are more factors than just the engine that make it wheelie, such as the gearing or tires, not to mention you have a swinger that makes it harder to wheelie.
When you say wheelie, what gear? my X only does it in first and second, and after second the suspension will extend but thats all.

Meh... "Why won't it wheelie" and "why does it smoke"

Kinda like asking.. "Why can't I do a burnout in my car and why does it miss so bad"

I'm not knocking... but honestly.. some basics could / should be done before even asking these questions....

Something must seriously be wrong if you can't pull a wheelie on a 200x. My daughters ALT50 will wheelie all day long. I have very serious doubts that the 1 inch longer swingarm has anything to do with it.

Do you have air in the tires?

Correct me if I read your post wrong but it looks like you said you had a 1 ft longer swingarm?if that's the case then there lies your wheelie problem.If you want wheelies then a longer swingarm isn't a good thing.

**hoosierlogger** · 07-09-2013, 08:31 AM

Holy crap it does say 1 foot longer!!! Yeah I agree that's the problem. I thought it said 1 inch. A 1 foot extension is a pretty radical change to the leverage required to pull a wheelie.

thanks for your responses, its a 10.5 comp piston was bored by local shop was honed too. head was done by shop upstate w good reputation. cam is webcams topend cam stage 4. has been ported, dg exhaust, big dg carb, runs good, a bit hot but good. gearing is stock. swingarm is 1 inch of course over not a foot! the angle the shock is at is less like this \ than stock.
blue smoke = oil thats what its doing
it used to wheelie in 5th gear with stock swingarm and stock motor no it wont hardly wheelie in any gear, when i say wheelie i mean a straight up catwalk not just a quick lift.
ive just been riding it as is since i kind of have to, just the oil smoke worries me with a new motor!!

**hoosierlogger** · 07-09-2013, 10:45 AM

You didn't line all of the gaps in the rings up on the piston did you?

**yaegerb** · 07-09-2013, 01:34 PM

x2....Hoosierlogger beat me to it. Did you assemble the rings on the piston? The gaps have to be offset on the piston, plus I have also seen where guys accidentally overlap the oil ring instead of ensuring the ends are touching and not overlapping. Either of these, if done wrong are a one way ticket to smokeville.

**hawaiirider** · 07-09-2013, 05:20 PM

i definetly offset them about 180 degrees from each other, i dont know about the oil ring overlap though? im used to working on 2 strokes, these 4 strokes are generally bulletproof
