For some reason my stock 13T sprocket is showing some wear and needs to be replaced. Chain and rear sprocket still look in good shape. I was thinking about just getting a 12T front to try it. I want to be able to pull 3rd gear better in the tighter trails. I have a couple concerns though for those that have tried it maybe you can answer them. My bike already has the airbox mod and the FMF rev pipe. (KDX220) I think I can get the rest of the season out of the chain/sprockets if I change the front. 1 tooth off front is like 3 more on the rear right?
1. Will I have anyproblems losing a lot of top speed in 6th gear?
2. Will I end up needing to shorten the chain to avoid going out all the way on chain adjustment?
3. Will this longer chain adjustment make the wheel base too long?
4. Has anyone taken 2 links out of their chain to compensate.
