Thanks Al and Monte. If you guys don't mind, I would appreciate opinions on where to start. I can lower the rear tire pressure if it is the way to go first. I have 15x 33 x15 Goodyear stiff sidewall rears, no tubes. I have been running 9 3/4 psi. Front shocks are full soft on extension, wheelie bars can go down as far as is needed, they are 66 inch long and solid, not sprung. At the moment the front has 54 percent weight on it,46 percent rear. I have about 2.5 inch of travel before the limiters hit, rubber bushings to cushion the stop.
I will have to wait a while on loosening the converter, but will get it changed now that I know for sure the true stall.
