[mali]

This must have been asked a million times, but i cant find any threads.

I need a selection of pinions for......

For a B4 with 81 spur

Oh its a 7.5 turn speed passion ultra sportsman 2 motor.

was thinking around 22t or 23t?

Hello mate

It really depends on the track...

Is it low traction or high traction? Are there any really big straights or is it small and technical???

I would start of with a 23 as I have found to be a good starting point for a 7.5 motor...of course that applies to previous generation motors

Hope this helps...

Regards
Argi

I run 81/24 on a Ballistic 7.5. This is spot on for a large track like my local at Southport.
