hey ive got a question since your messing around the motor. ive got a 1999 gz 250 myself and i bought it used with only 6000 miles and since ive rode it ive noticed that i seem to run thru all the gears quick and i can only top out at 50 maybe 55 and thats really pushing it to the limit and i dont understand whats going on with it. i thot maybe it needs a tune up or timing needs to be reset or valves need to be really cleaned and reset but i honnestly dont know and im getting fustrated trying to figure out whats going on and how to fix it. so could you or anybody elts give me some ideas on this, it would really help. thanks

Just like goose said check the jetting or maybe a exhaust system and a re jetting on the carb.
