Has anyone heard of a 440EX needing as high as a dynojet 180 main jet?
The reason I ask is because I did another plug check after a 10 second long 5th gear run at wide open throttle.
This time a had the dynojet 175 main in and when I pulled the plug, it looked like I could go richer yet.
Also for the first time today, I got a little backfire after playing around at part throttle for about 2-3 minutes. This means I need a richer part throttle setting right?
I'm at sea level and I run 100 octane race gas.
Thanks, Steve.
