Hello to all. Just hooked up on this site and looking for some info. About a month ago just picked up an 07 XR650L after being out of riding for about 10 years. Now I feel stupid for waiting so long. I love this bike. The way it pulls on the low end, I think John Deere must have had something to do with this engine. But then in turn the way it comes alive at 4500 rmp still shocks me at times. That brings me to my frist question. Does anyone know what the RPM redline is on this motor is. I did install a tach. I'm a geek like that and like to keep track of these things. That too I feel this bike has way to tall of a 1st and 2nd gear. Would like some info on sprocket changes. Would like to try a 48 tooth rear at frist and see how it works out. Any input from someone who has changed the gearing whould be great. I do ride this on the street time to time and it will still have to be able to run down the highway at 70 mph now and again. The only other short comings I have found so far outside of this are the bars. Tossed the stock steel ones for a set of Fly CR bars. That and just swapped the rear tire for a Dunlop D606. Seems a little out of balance now, may have to swap the front also, after I play around with the shock settings some more we'll see what happens. Outside of this...... Hell of a bike !! Thanks for any help, look forward to talking with you.
