Hi gang, new to the board... I've heard so much about changing the cdi, removing the oil injection and changing the pipe... What I want is more speed. 15 mph does not do it anymore... My boy has had this thing for 2 month's and he has outgrown the performance... what do you suggest.

2003 scrambler 50..

 

First thing change the pipe. It's the best bang for the buck!

 

or you could just upgrade to the next biggest size 90??

 

Did you remove the exhaust restrictor yet?

 

theres so many things you can so removing the restrictors will help but i suspect you wanting more than that
a pipe rejet and air filter would be your 1st option
70cc cylinder kit could be your next hop up and theres alot of clutch mods you can do to get the RPMs up
