Re: Motor studs?
50 mph difference Kim has done 238 at Bonneville and 188 here
but we have not run here for several yrs due to weather
my best is 229 on the 750 and 257 on the busa , Kim fits the 750 better than me and it shows in the speeds
a little richer, not enough to be an issue and much better than lean
you will be tuning on the rich side anyway to keep the piston temps down on hi boost levels
