Motor studs?

[Maj750]

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

What would be better suited do you think, with my current knowledge id be aiming for around the 12.5/1

[Maj750]

try 11.5 on boost, 12-12.5 off boost

Will keep that in mind when tuning, just had everything shipped from orient, should be here close to the new year so I can finally start the assembly.
