what is the best part in a jm 250 to increese performance???

 

What kind of performance?

 

idk just over all power/speed any thing just suggestions

 

Have you got the larger jets and smaller front sprocket yet?

 

no and i dought i will the jets i dont think i need because the plug is light tan..and the sproket well i dought i will get that because im under the age of 16 and live with my parents

 

If you doubt you need the jets, you need to change the sprocket. If you got it from Raceway, John will send you one for free! So call him and tell him you want a 15 tooth front sprocket. If you didn't get it from him, maybe he will sell you one. They really aren't that expensive. Maybe $20 shipped... I'm not sure.

You have no understanding of the principal/effects of gearing changes.

Replacing the stock front sprocket(17) with a 14 or 15 tooth will have about the same effect as doubling your HP/Power.

 

A smaller front gear will give you more torque over the entire powerband. That means you will change gears faster and pop wheelies without standing on the seat.
