I have a 94 CR 500 that has a 90mm bore rather than the stock 89. Right now I just put in:
The following stock settings:
170 main
55 pilot
Stock Needle (1368) in the 3rd clip
And 1.5 turns on the air screw
I am also running the stock pipe and muffler on this 500
I mix my fuel 32 to 1 on pump 91 octane.
I guess technically the displacement is closer to a 502
Any ideas if I should adjust jetting based on this slight bump in displacement? I ride at 900 feet above sea level and it's been 50 to 60 degrees lately.
I did drop in a new 90 mm piston and thoroughly cleaned the carb. It just doesn't seem as responsive as my other 500 which is a 97 with a stock bore where I run the same settings except for a 2nd clip position on the needle because I have a Gnarly pipe and Turbine Core silencer.
I would appreciate any thoughts.
Thanks ,
Cody

The bore dosen't matter, its what the motor wants that matters and not so much the mix. Why not 50:1.
A 1468 needle / DGJ seems to be liked very much. Or try the 2nd clip with the stock needle.
