I broke 4th gear on my yz450f and am trying to fix it myself so I dont have to spend a lot of money. I took apart my bike and now have the engine out...does anyone know how to fix this??? Or do you know where I can find instructions on how to fix it? I have to get into the engine and pull the gear out but im not sure how to take it all apart???

Thanks for any help you can give me...

read the manual and be prepared to totally tear down the engine, and split the cases. Once the cases are split, you'll pull the tranny and replace what you need. Take lots of digital pictures as you tear everything down and you can reference these with the manual when you put it back together.
