Does anyone else have problems with lots of dirt and sand getting through the gaps in the spur gear cover? If only it had an extra screw on the side closest to the shock tower. I really hope someone brings out an aftermarket motor plate and gear cover that is 100% sealed! I do alot of running in the sand and usually I have to use electrical tape to seal the gear cover or else I will end up grinding away the spur and pinion!
The cover on mine worked great for some months keeping dirt out, but lately it has started to let in small grains. So a quick fix I did was to loop a elastic band over the gearbox, and pull it over the gear cover. Not a 100% seal, but worked well enough for now.
