Got my 350x back but it smokes worse then a 2 stroke! HELP

**cragster** · 05-21-2006, 10:19 PM

Well i paid this guy 500 dollars to put on a new head and cam on me engine. he said he had a good used piston and rings he was puttin on it..blah blah. Anyways he gets it running and it runs good. Seems to be enough power..Wheelies easy but it smokes worse than any 2 stroke i guarentee it. I just went out and started it to show you guys a pic but the cam didnt pick up the smoke very well..also its 10 at night and i dont wanna wake the neighbors (anymore) lol. Ill get some pics tomorow. The guy said he honed it a bit but used them stock piston/rings. Is there a way to stop the intense smoking. Or do i have to put another couple hundred in it and buy a wiseco piston?

"he said he had a good used piston and rings he was puttin on it" A HUGE NO NO. If your lucky it might just be getting broke in after the "Used piston" was put in.

He put a 350 4by4 top end on it and he used the piston and rings off that one. Along with the cylinder..... But he honed it a bit.

give it a good ride tomorrow 4 strokes have a reputation of smokeing for a little wile after a rebuild like that, could be the asslembly lube burning off??

**cragster** · 05-21-2006, 10:29 PM

I already went thru over 2 tanks of gas. We went ridin yesterday on it and today lol!

**Bryan Raffa** · 05-21-2006, 10:33 PM

oh well then i would think that you have a problem. look into a new set of rings for that piston....LOL

**cragster** · 05-21-2006, 10:50 PM

yeah i think so......

**Yamaha Tri-Moto** · 05-21-2006, 10:57 PM

Probably would have been a good idea to just buy a new piston and rings, there not that expensive. Maby you could take it back to the guy, and tell him to do it right lol.

**cragster** · 05-21-2006, 11:08 PM

yeah. It was hard enough to come up with 500 bucks in 2 weeks with no job. Now another 2 or 3 hundred. I could have got me another engine or 2 already.
But i will say. this thing is fun 2 ride. Ill post some pics and vids if i can tomorow...

Never,never,never, use a Used Piston and Rings. Did he do the Valves too?

For $700 you could have got a New NOS 350X engine.

But if it runs fine, I would not worry about it, its just a bit of smoke.

I quote from bryan raffa " fix it right or not at all!"

I think that $500 for some guy to put a USED top end on your X was way over the odds. Did you supple the top end too? It probably only took him 3-4 hours of work, so thats about $150 an hour lmao.

What you should do is go back there ad make the guy fix it properly, for no extra money. Or pay for a wiseco piston and have him fit that.

Who knows what that used piston was like.

**team-red-rider** · 05-22-2006, 10:12 AM
