about 3 months ago i rebuilt an 87 warrior. Everything was done. Durring the breack in prosses it would run fine and clean. after a week i bumped it above 1/2 throttle a little. It was smoking a little. When i got back to the truck the air box was melting where the pipe was rubbing...... ok, it smoked a little at the start, it was from a little burning oil and a rick condition. Well, now that winter has set in, it smokes much untill hot. I had to fill it up with oil after 2 weeks of riding. I belive when the air box melted some of the plastic was sucked into the cylinder and melted and fried on the the oil ring. Is This possible. I have stong compression and also it has had no loss in power. What do you think?

 

yeah that happens it shouldn't be your air filter. my warrior which is an 1988 smokes when it is cold until it warms up too. mine starting doin it after we overhauled it. it not the air box because mine is fine. but mine smokes too, we think it is something to do with the jug.

 

Just rest assured it ain't healthy. You won't like the remedy for this problem.

 

Health? Who's watchin? I was wondering if It could be a bad gasket? I am going to re-torque the head bolts some time.

 

What colored smoke is it blue black?

 

Did you break the glaze in the cylinder before re-assembly? Maybe the rings on the piston aren't seating well against the cylinder walls.

 

Did you re check the valves after the first few hours? Do you have any problems starting it, or noise that you never heard before?
Are you sure it is timed correctly?

You also mentioned a melted airbox. I'm guessing from the pipe being so close? That would tell me there is a lean condition. If you ran it lean for a long period of time, then your rings could be feeling the pain too.

 

It still has solid strong compression. So i belive the rigs are fine exept the oil ring. Rechecked the timming and it is still aligned. Have not rechecked the valves, but off set valves would casue loss of power and i still have strong power. IT has nver ran lean. Always rich. The airbox melted because the pipe was "rubbing it" stupid me! We have played with the jetting and it is running a little rich. The smoke is dark blue, but it smells like an extreamly rich condition. Have leaned it out but it did not help. When we took it to colorado (3 wks after brake in) IT did not smoke at all. It is not making any new sounds, but i do not know what a stock warrior sounds like, (we purchased this one in non-running conditon) but compaired to our wolvy, no. The only problem i have starting it is the procedure. The relay witch got pulled out and lost by the chain. got a new one and it still wont start. I have to turn the ley, pull in the clutch lever, press start and slid it into reves for it to turn over. Then it will fire right oup on the first try.
