250-500cc Exhaust problems

Hey I recently bought a 1992 360. when I tried to take the gas tank off, the petcock on the right side interferes with the exhaust, so I had to tediously remove the petcock. Does that mean the whole exhaust pipe has been tweaked? Also on the left there is a y joint in the radiator hose which rests on the exhaust.

Also, the o-ring gasket in the exhaust is broken, is there a specific replacement I need or can I just get an oring from ace hardware?

ya it's likely been bent good by now. take old O ring there to compare what's in stock.

the exhaust o-ring is a Husky part, heat type o-ring
the exhaust will need to be jigged and straightened, or take it to someone that can heat and reshape
the y should not be touching but one of mine is very close and never had an issue

A bearing service etc should be able to replace the O ring. You need a Viton for heat and oil etc resistance. I 'glued' mine back in the pipe recess with high temp silicone and works fine.

Ok so I bought a really thick O ring at the hardware store so maybe that will work, if it fails I will look into finding a good heat proof one. I'm not going to worry about reshaping the exhaust though, I'll find an fmf pipe for it sooner or later

if its a 92 it has an odd exhaust, there is no new replacement for it
the 92 was the first 360 and 93 the went to a different pipe configuration
is your head pipe over or in the exhaust port?

dynoport will sell you one. for sure the only option other than another stock unit

had one on a 92 360 great pipe
good to know that they still make them
