This quad has been sitting on the ranch for about 4 years, I decided to start messing with it and found the plug keeps getting fouled, it starts and runs for a day but I need to pull the plug and clean it or replace it the next day before it will run again. It sounds like it may have a leak in the exhaust and it was suggested that I need to replace a dougnut style seal??? I took the exhaust off and could not find any such part.

So my question is does anyone know what Im talking about or can anyone suggest where I can find a diagram of all the exhaust parts for a 91 TRX 350.

Thanks

 

Your Doughnut Gasket or seal should be on the end of the exhaust going into the head. Not sure if this is the answer your looking for though.
