Maximum hp for a Scrambler 400

Hi guys,

My mods are RCR top-end pipe, PWK 39mm carb, v-force II reeds, open airbox with Uni filter. Does, anyone know at what rpm the motor should produce its maximum hp ?

Thanks !

I'll second that. Give Rick a call, super nice and very knowledgable. He'll get you some tips on the best operating rpm's for that particlular pipe.

Seems to me that Rick told me one time it was around 6600, but I'll agree that it's best to call him. He usually answers the phone himself.

400 2 stroke peak at 6500 rpm,this is where the engine built the most horsepower,but a higher revving pipe will get you a faster full shiftout at around 6800-7000 rpm without hurting top end too much.
