You need ALL the gears the two shafts shift forks 3 of them shift drum all the gaskets your bike is new the seals should still be good :) about $800.00 give or take and your yz manual is worthless you will need a wr shop manual I looked at the microfinch for were the gears go :)

Yeah youc an do it, but it will cost you ALOT of money, more than $1,000 thats for sure.

Yeah, but why would you want do do it anyway? If you are having gearing problems just do some experimenting with different sprocket sizes.

I was thinking about doing the same mod. I just purchased a one tooth smaller counter shaft sprocket to see if that will work for a little wile. I also do trail riding\hill climbing\open desert,so I'm not thrilled about loseing top end speed.

Sprockets can only do so much. I have an 01 426yz that I dual sported and 1st gear is way too high on rough stuff or change sprockets and no top end. I am thinking recluse. :)
