Hi to all! I just picked up a 2001 blaster for the my daughter. It has a K&N filter with 2 big holes in the airbox lid a FMF gold pipe and silencer combo. I'm not sure what size jets the carb have but assume they have to be larger wiht the mods already done on the machine. It seems like a fst machine but not sure how fast compared to a stock one. I was also told that you only need to use the clutch for starting and not for the rest of the time is this true?? I had 2stroke when I was younger but have always used the clutch through all the gears. Will not using the clutch be easier on the machine or harder? She really like the bike and would like to get interested in taking it to the track someday. Thanks for any advice and this seems like a great forum! I have had polaris 4x4 quads but not race type 2 strokes.
