Hey guys about a week and a half ago I purchased a 1997 Honda xr650l, on the test ride I could definitely tell the carb/tank had bad gas in it because it would sputter a bit, however the price was right so it came home with me one a trailer. First thing I did was drain the tanks and put some 93 octane gas in it, it perked right up but from what I've read I just expect it to be faster than it is. I'm about 6 foot 140-150 lbs and I read about how it wants to wheelie all the time but when i have to try for the wheel to lift in first gear. The bike is de-smogged when I bought it and I just put a new spark plug in because the old one was toast. I fooled around with the tuning on the carb which helped some but I might be expecting too much. The bike still has a paper filter on it (not sure if that really makes that big of a difference) a fmf mega max slip-on on it. I had also looked into doing daves mods to the carb until I realized it's a mikuni, not a keihn or however it's spelled. Also the bike has been getting 33 give or take mpg on a tank which I feel is pretty bad, although I have been romping on it quite a bit. I appreciate it guys any help is better than none.
