98 600f3 runs but very poorly, speedo said i was going 110mph when i was going about 40mph and the tach just jumps around all crazy, bike will rev up halfway alright if i slowly give it gas, i am not a mechanic but would like to fix the bike myself, didnt know if it would be like a spedo sensor or smething electrical like that or if it would be something to do with the gas and air mix, if someone has advice please e mail me at derekdaniel08@yahoo.com
