GPX 125 with crower cam?

Is anybody out there running a GPX 125 in stock form with only a crower cam installed?

I have a cam for my X4 that I may install soon, but want to know what to expect.....

Will I see any benefit?

Reliability issues? (valve springs?)

Require jetting or carb replacement to keep up?

Any help would be appreciated.



It is a great cam and you should see an increase in mid to top end power. You wont be dissapointed.
