Thought i would throw my 2 cents here.. I am running a TVI 720 big bore with twin 39's. I have 22" extreme's with 15 / 42 gears.. This combo seems to work real well for me up here on the Oregon dunes. I am around 200 lbs. I tried the 14 tooth thing.. All i can say is if you go that way HOLD ON and velcro your butt to the seat and get at least a 6 over swing arm.. even with that your front end will still be real light

 

yah those twins put up some great power with those 720's if tuned right....i didnt know u got the 720, did u get the race head also....if not wiat untill u do, very explosive power when tuned right..[img]i/expressions/face-icon-small-wink.gif[/img]
