I may just put new gaskets in everything and re-seal the crap out of the exhaust. I put some copper RTV on it the other day but it didn't seem to help. I did get anxious and fire it up before it was cured though.

I would check the o-rings first. My Saito 1.25 never had an issue with the stock pipe.

My diaphram was OK, but the there was crap in the screen and I had to clean the needle seat.
