I have a 2000 zx9r mostly stock with Yosh. slip on exaust bike runs great and doesnt smell rich or leak gas, has an unbelievable 2800 mi. and I got this bike about a month ago. The first time I rode it I easily got over 100 mi. and was curious to see how many I would be averaging so I set the trip after filling the tank each time. I ran about 80mi. the first time, and filled all the way up again and hit 70mi. before having to kick the reserve on. Does anyone no why I am not reaching 120-130 miles per tank? I dont run the bike hard a whole lot and dont get on the highway much either, mostly back roads to school. Also is the reserve 1 gallon?
