Hello All,

Can someone tell me what the proper air/fuel ratio my 04 750 should run at?

Thanks,
Greg

around 14 to 1

Most motors run at full trottle should be around 12 :5 A/R some people tune alittle leaner some tune alittle richer. At idle around 14:1 and part throttle about 13 :1.....but there are many different factors that change these numbers up or down.

I would favour 12.5:1 at the top end for longevity. Leaner will make more power, but at what cost .....

Thanks for the replies.
