I already ordered my bolt on kit from Max Power its the 480 kit for my YFZ. It should be here Tuesday. I was wondering what gearing you all think would be best to run with it i do some trail riding but mostly wide open roads and some drag races on the weekend with people who come over my way.. But everything that is done to it is posted below in my sig. I'm using stock gearing now..

 

Any help would be greatly apreciated

 

It would probably be best to wait until you've got the engine dialed in to make gear changes. If it turns out to be a torque monster, you can gear lower (numerically). If it likes to rev, gear it a little higher. Tough to guess on better gearing without knowing how it acts with stock gearing.
