Lowroll Posted June 28, 2016 Report Share Posted June 28, 2016 My bike currently has fmf sst's on it, I came across PC platinums at a really good price so I picked them up and they come in tomorrow. So tonight i'm going to pull my pipes, and carbs to do a leak down while i'm there. while I have the carbs off I was going to go over my jetting for the difference in pipes. I have a HJR ported 4 mil, 23cc domes. about 150 psi compression at sea level running 50/50 110 and 93 at 32:1 +4 timing, 35mm PWK's with CEL needles and K&Ns current jetting is 50 pilot and 152 mains with the needle clip on the 5th notch. I know my needle shouldn't be that rich but after all the carb tuning I did on this thing and I had a bog just off idle I could not get rid of without going farther on the needle. Anyways, any suggestions for main jets after the pipe swap? Quote Link to comment Share on other sites More sharing options...
sheerider11 Posted June 28, 2016 Report Share Posted June 28, 2016 Why are you running 50/50? Your main shouldn't really change between those pipes Quote Link to comment Share on other sites More sharing options...
Lowroll Posted June 28, 2016 Author Report Share Posted June 28, 2016 When I talked to kevin its what he recommended. we even spoke after the engine was together and he had my compression numbers. Its not truly 50/50 now that I think back. its 2 gallons 110 and 3 gallons 93 Quote Link to comment Share on other sites More sharing options...
