bigboybanshee Posted May 24, 2005 Report Posted May 24, 2005 How clean is your air filter(s)? If changing your pilot jet didn't help, and adjusting your idle/air screws didn't help either, I'm not sure where to point you....Have you advanced your timing? If not, that "could" help eliminate your problem. What kind of porting did you have done? Quote

What kind of porting did you have done? 373234[/snapback] I clean the air filter every ride dirty or not.No,I have not advanced the timing,But I do have an adjustable timimg plate.I have it at 0 because I'm not sure if it will handle +4 with pump fuel.I ride trails and carry fuel,but sometimes need to stop and get pump gas which is 92 or 93.I'm at 150 lbs with porting.Kinda on the edge. The porting was done a few years ago from PSI in Wisconsin.It's a mx/trail porting.They call it stage 5 which is at the max.... I'm going up to the trailer this weekend and most likely try and richen up the needle and see what happens.I'm a little shun about trying to advance the timing right now.Other than this any other ideas????

If you were at 160, I'd recommend maybe running a 50/50 mix (race/pump gas) with +4 timing. But with you at 150, +4 would be ideal for you...especially with the porting. I ran +4 timing at 150 psi on 93 octane with no problems at all; no pinging, no detonation. If you have the adjustable plate, try bumping up the timing to +2, see how it runs. If better, go ahead and put it on +4. Quote
