The bike lost the ability to shift into fourth gear. I opened up the gearbox, and the double gear G11 won't slide off the G4 final drive shaft. I see 5 cracks.

When I assemble a motor or gearbox I use a product called Xcel plus. https://xcelplus.com.au/products.htm
It seems to do the job it is supposed to. Over thirty years ago it was called something different and then there was a big corporate bunfight over the formula. Basically SUPER slippery dipper product that puts a microfilm on surfaces. I know a lot of professional racers use it and are not allowed to say so due to advertising, sponsorship etc. Check it out for yourself.
