I have the stock gearing in my 98 xc700, and 2 years ago i installed a 136" track. I've tuned the clutch and it rips and roars the way it is, but i was looking for a little more punch on the low end. Does anyone know what type of gearing set up would work? I ride mostly trails, but rarely go over 90mph, so top end isn't a factor for me. Any help would be appreciated.
