Ive got a 2000 XR650R with stock 14/48 gearing.. uncorked/jetted... I have it tagged and curious about running some slab.. Wheels are stock size... can I run this bike at 60 mph for extended periods? (10-50 miles)what is a good RPM to shoot for on runs like this? I have a 15cs I could put on but, hate to loose any of the torque. As it is now my Vapor reads 5600/5800 @ 60mph I think but, not sure on this.. what a sweet ass bike.. just dont want to trash it... thanks all..
