REV-XP/XS Chassis: Renegades/Freeride/Backcountry
Thinking about doing a big bore to my 800r in the near future. Just wondering if anyone is running any 860's at low elevation. I mainly ride in Wisconsin and the UP of Michigan. We do a bit of trail riding, with a decent amount of boondocking. Just wondering what heads make the best hp with BJ's...
