What premix ratio do you run?

<< < (2/8) > >>

tharden:
I run 50:1 with golden spectro.  Have not had a problem.  I do not desert race but under those condition I would think 40:1 would be more appropriate.

KXcam22:
I ran 60:1 Belray MC-1 in my 500.  Now I am runing 300:1 Belray MC-1 in my 450.  Cam.

im still tring to figure the sound out,i has pinging in my exhaust(the big bladder part) when i was racing in the high desert,almost 6500 feet at the top of the mountain(out side of fernley,NV).i rode the bike sunday here in Sac,CA and everything was cool so, i figured it must have been the altatude and the air/fuel mixxer. any ideas?

martinfan30:
It wouldn't be pinging up that high. Like already mentioned, it'd be real fat and running cool.

BTW, are you from Fernley? I live in Dayton.

turtle22:
no i live in Sacramento(citrus heights) but i have started racing in the MRANN. it races mostly around that area. abunch of my buddies went up and rode moonrock on sunday. i did not make the trip,next time.   
when i say "fat"what do u mean by that term?
