best gearing for my strokah..

[JAC3]

52.6
54mm
2000 grab
2000 torque
pg long
30mm carb

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
zx trans 54grams

was running 6.5-1 but it feels like something is holding it back motor wants to go more..i think belt slippage.
havent clock with gps yet but i bury 90mph on the pg speedo dont know if its accurate what do you guys think?..
now im running 6.8 sounds and feels better..
what can i don to improve my setup maybe hit 100mph..hehe

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.

Bump anyone ?..

Bump anyone ?..

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


Is that the big PG for strokers?

Hi.. my tach wasn't installed at that time I will install and find out today.. To get higher rev go down on the weights right? I had 3 8g and 3 9grams..i marked the vara and belt goes all the way up.. Thanks

Here is the official trafficjamz "speed chart"

10000 rpms + 6.3 gears + maxed out variator(0.8:1 ratio) + 90/90 rear tire = 90.8 mph
