thanks for the info on gear ratios.i think since im running stock for now im gonna just go with a 12 tooth on the front,from all the feedback ive gotten it seems like my best choice but who knows

 

Intead of dropping to a 12, try a 39 in the back. It will be easier to find, but more money. It will give you more pull, but you will keep topspeed, compared to just going to the 12.

 

very smart move I drag race 400's with exhaust on mine and win most of the time I have tried gearing up but then it lacks low end power so I set up for out the hole instead of wining top end. Go to rocky mountain for your sprokets and go with the primary drive brand they are good gears and RM is good on prices and shipping. Good luck with that 300 they are very fun bikes once some mods are done. I just wanted more so i just got the 700r and I will start moding it soon.
