heres the story today i was out riding me and a few of my friends i pulled like a 3 mile wheelie down the highway (which i have done before so its nothing different), when i set it down it was revin kinda high but not limiter, my friend behind me said there was a lot of smoke when i set it down, it didnt make any noise or run different, so we stopped at a gas station and when i started the bike up it just poured smoke out of the pipe but still not makein any noises or diein out. i took the top off the engine and there was some oil in the airbox, i thought it might be the valves or the rings but i'll look more tomorrow.
i just wanted to know if anyone knew what it could be.

thanks -Jesse

 

Maybe when the bike came down the valves slapped hard and brok a guide or something. you also may not notice if you valves are bent as sometimes its just enough to make it off. I would say get a valve job when its apart do the rings and your done

 

I agree......make sure you do the rings.......while its out check you crank bearings......

 

um maybe from doing the wheelie oil overflowed into the airbox if its not making any noises i think thats all that happend your engine is fine

 

thats what im hoping for too, but the oil had to of leaked down to the pistions b/c it was blowin smoke out of the pipe, thats why im really thinking its the valves, i hope i dont really want to buy a new engine

 

If oil gets in the airbox it gets sucked into the cylinders through the intake valve along with the incoming air. Nothing has to be leaking or broken for the oil to get into the cylinder if it's in the airbox. Like was posted before if it aint making noise it's probably fine. I would fire it up for a little while and see if the smoke clears up. If it starts making any noise or the warning light comes on then shut it down.

I'd bet a buck or two that it's ok. If you've already hurt the motor (Top End [valves]) then you're probably not going to hurt it worse by running it for a couple minutes. If the piston rings or pistons themselves were hurt it's possible to do more damage but I don't think a wheelie should have hurt the pistons or rings. If you did then it's probably gonna need a total re-build anyway.

 

What he said.

 

your motor is fine, NOW GO MAKE MORE WHEELIES

 

And go pickup a rear oil pickup!

 

nothing to do with his problem

 

Its still a good idea for wheelies on a giixer IMO.

 

its fine as much as i want to sell you a motor yours is fine. That happened to me when i used to actually ride my bike on the freeway, all i did was clean up the oil out of airbox and air filter. Let it run and the smoke will clear up.

 

im gonna fire it up today and let the smok clear out, thanks for all the help,
and if the motor does go i'll give u a call b/c i'll need to buy one from u.

 

it is a good idea, im gonna put one in this week, im gonna change the oil anyways just to make sure and put a pick up in

 

i have one more problem, im putting my bike back together and i have to fix the timing b/c i took the cam gears off, so is this something i can do myself, i went and talked to a mechanic and he eplained it to me but its still gonna be my first time, should i have someone do it or is it easy enough??

 

It's probably just the blinker fluid

Your bike is fine. That happens to my friends r6 everytime he scrapes. The oil will burn up and the smoke will stop

 

That would happen to my fiddy also.. when i 12ed or wrecked reall hard the crankcase vent would dump oil in air box then smoke... Whoohooo its perty!

 

when you line it up, it should be 14 pins. its not that hard to set timing just a pain in the a$$. have to get it perfect.

 

I got a motor for sale in the classifieds here on stuntlife I will see ya for a special deal $200 plus shipping $50 off what I was originally asking for!!!
