I'm running 111 oct. klotz and 4oz. to a gallon mix.
Motor
392 cub. 39 pwk's, vforce 3 reeds, 1-4 5/6 m duneable tranny, lock up with soft springs, shearer's oof pipes, stock cdi, coil, stator and flywheel.
Cranking comp. new is 160, Present comp. haven't checked it yet.
I used to run high 11's at 103 mph, now 12 flat or 11.9 at 100 mph. Which is why I'm thinking I should just tear in there and change out the seals. I've got more then at least 160 runs on this motor.
sorry i don't know what rpm's I'm at going through the traps, I'm the only one on this side of the pacific ocean that races a quad on the 1/4 mile.
Thanks a bunch for the replies.
