Just bought my son an '03 YZ85 in super mint condition. I bought it from a guy who bought it as a first bike for his 10yr old. Needless to say it was waaaaay too much bike for an inexperienced 10yr old. My son's 11 and went to the YZ85 from an XR100....anyway I'm rambling.. The bike was hardly ridden and well maintaned so I can't think of any reason I can't hit 5th gear. It runs excellent, it's just only giving me 4 gears. Any ideas ??? :blah:
