yeah I figured that was a heck of a handicap so I was trying to make up for that in gearing, well at first we ran 13/65 and had 5170 rpms, then we went to 12/60 and got 5170 rpms, then to a 12/62 and got 5250 rpms, then to a 12/63 and turned 5500 rpms now we are at the 12/64 and got the 5630 rpms and with all this he still runs 3 or 4 th. been experimenting with tire pressure also run 4 1/2 pnds on the L side, and 5 1/2 pnds on the R side. was thinking of going up alittle on the tire pressure to get roll speed from it.
