OP whereshaldo Hooked Stella 2T 150, Honda C70 Joined: UTC Posts: 423 Location: Seattle	UTC quote I ordered a 65 tooth primary drive to put in the VBA but it does not look like it will work. The 67t from the VBA has truncated "points" that mesh with the gear stack and the new one has pointy "point". Any advice other than that I have a nice paperweight? Hal

I think only DRT makes one for the older boxes… https://www.sip-scootershop.com/en/product/primary-driven-gear-65-teeth-drt-input-shaft-695_40436950

Welcome to the paperweight club!

I've got this 63 tooth paperweight. If you can make it work I can send it for $0 + shipping.

I need to count mt gear teeth and figure out my drive ratios I have a 4 speed box, but I don't know what the gears are. I don't know if a 63T primary drive will be too tall for the hills of Seattle. I also have an offer for a 65T.

I may turn my 65T into a Flavor Flav inspired scooter neckace.

I've purchased a DRT clutch gear and it didn't fit - too large. But the next time I open up the VNB2, I may try to change gearing since changing the 7spring clutch teeth didn't work... And If I start ordering, I may end up with a gear mobile hanging in the back yard!
