hi there, like the title says i am not a motercross man (though i like them just dont have the money for them
)
anyway ill get to the piont
i will be soon getting an aprillia RS barrell (wich wont be going on an aprillia) to do some porting with (have done this many times so this is not a problem).
but the problem is tuning for a wide powerband. never had to do this before. there are some obvious stuff that i will be looking at
-Exhaust builts for a wide powerband
-flowing of all ports
-checking the reed area
- a less obv one is staggering the transfer ports.
i thought this right be the place were people have experience in tuning for wide powerbands. what extra things could i do to give me a wide powerband? (any case mods would be most welcome too)
cheers, a fellow two stroke moter enthusiast looking for a bit of a hand, charliec

You mean the RS 125? With the Rotax engine?

yes thats the one, sorry for not saying

Disabling the powervalve and positioning it in the closed position will certainly soften the hit.
