Spur and pinion gear teeth?

[Jayjay]

So did a lot of work on my Baja motor 36cc bore / port and polish changed everything in the car except the factory spur and pinion gear and I have to upgrade to metal because I keep shredding the plastic ones . Factory is 57/17 . Would 18/56 be best if I’m on mostly loose dirt and sand ? Or what would be a better setup ?

19/55 has always been the sweet spot for my bajas,
8k clutch spring to go with it, always worked well for me

Will try it out . Running 10k spring on an FS clutch currently

Tbh I'd probably go to an 8k spring, that 10k spring isn't helping you with shock loading your driveline. I run 8k springs in my 5ives and it's plenty to launch the truck, I have an 8k fiber clutch in my baja and it lifts the wheels with no issue on a 30.5

Only using 10k because it was what Taylor recommended with their parts and motor .
