I question this pass because of the short times thoes are drag bike short times & the end result should have been in the high 11's the other guy was just running to the 1/8 on a sled a buddy of mine also had this w/his stock v max a 1.337 & the other guy had a 1.311 looks good on time slip but no way computer glitch???

Yes you are right,if you acutally ran the 1.3 60 footers,which means you gained 4/10 s on your old time,you now should of been in 11.8's somewhere,so there lights made a mistake,on either the short times or it did not calculate properly on the long end,either way you have been very consistant all summer,and i cant see why you would of just magicly would jump out 4/10s quicker with out doing something major to your bike other than tire pressure. But what its worth,i enjoy reading when ever any of you guys make these runs and show us all of your gains to date,it shows this bike is still preety darn quick for a big cruiser,keep up the good work.. :bigthumbsup: :doorag: :super:

I am not a drag racer so, don't fry my chicken, but why are you running only 34 psi, you ran faster with 35, have you run with 42 in the rear? Again, forgive, because if I was racing it would be "really fat guy racing", and the leathers would wieght as much as my wife.

Trying to learn.

you may run faster top end with more tire pressure, but in Drag racing Traction is the name of the game, the race is won or lost in the first 60ft. lowering the PSI gives the tire a bigger contact patch, hence better traction. with factory rated tire psi, you wil just sit and spin at the green light. also is why a very good and smokey burnout is best for traction along with lower tire pressure.

stock rear tire ran 31 psi yesterday & the bike hooked even better 60' went down looks like that will be the psi for now waiting on the big air from hal to see if that improves the bike or just lose 30 lbs to put it in the 11's
