Post by JAC3 »

goal 90mph plus highway

just cant decide what gear to run i have
8.4-1
8.0-1
6.8-1
6.5-1
5.5-1

was running 6.5-1 but it feels like something is holding it back motor wants to go more..i think belt slippage.

What tires are you running going that speed. Too long on a wrong rates tire can be trouble. Get a pic of that bad boy doing 90 on the speedo. I'm planning on running 6.8s on my w/c 121cc. I run Pirelli diablos on my 91 mph Zx. But those are 12" wheels and I need a killer set of 10s for the elite.

I have some 6.3:1 gears that would be perfect for your goal.

Any gears over 7.5:1 will be to short to go 90mph :imo:


Is that the big PG for strokers?
