hi guys.
i own a KTM 125 exc 04' and i want mostly to deal with motocross.I need some help with the conversions that i have to do.
i've set my suspensions for MX use. I've changed my exhaust with the SX exhaust.Except the electric ,stants ,lights ,rear wheel ,fuel tank and jetting settings what else do i have to do?

please help.

The stator does not matter much. The EXC should have the 2k3 stator/flywheel that is heavier that will help with stalling. If you desire a lighter flywheel you can change it out to the 2k2 or 2k1.

The transmission is going to be the biggest job. The EXC tranny is not ideal for motocross. You chould be able to buy an sx tranny for about 100 bucks US. This is a bit of a big job and will require the cases to be split apart.

The SX CDI module will give you a better timing curve for MX.
