Title: Warrior 350 help
Post by: Vumad on November 26, 2009, 03:14:17 PM
I'm having engine troubles. I think it's a valve problem but I have not got that far as of yet. I need a better set of allen's before I can get the covers off.

Meanwhile I had a question about the exhaust. The exhaust where it connects to the head has a phlange on it. On my bike the phlange does not rest smooth with the head. It is about 1/8"-1/4" off the head. The bolts don't tighten down any more. Is there something that is supposed to sit between these parts? Is it suppose to be flush to the head? I know there is a gasket but the gap is pretty big to be a gasket. I figured the gasket is probably at the tip of the pipe.

Sounds like you need the head pipe gasket.

Thanks for the reply. I'm going to look into that just because it doesn't look right.

I can't find my 3/8" drive allen sockets but I did get the covers off. The adjustment nut came off the exhaust valve. Doesn't look like there was any damage to the engine. I should be back at Croom by next weekend!
