kx /kdx smooth out the power ?

[andy johnson]

hi folks , ive built a kx/kdx special and want to smooth out the power.
ive got an fmf fatty pipe(modified to fit) standard kx 125 silencer and a v force reed block.
im looking for ideas on how to stretch out and smooth the power, a few ideas , longer silencer ? reed block spacer ? would an frp torque ring help ?
thanks in advance

well, what do you mean exactly when you say KX/KDX special? What components are from which bike?

I will guess it's an 04 kx125 with an 89kdx engine. That's the common surgery, anyway.

The e series KDX is known for it's smooth powerband. I wonder what could be going on with yours? What exactly is it doing that you'd want to change?

 

[andy johnson]

id like to mellow out the powerband or stretch it so it builds more gradually and doesent hit as hard when it kicks in.
yes its a kx chassis and kdx motor.
cheers

A flywheel weight will certainly help with that. Torque ring will help a small amount for a lot less money.

jetting...maybe a throttle cam system...not really sure. I had to put a throttle cam on my 300MXC. It was just beastly and hit ridiculously hard at mid-throttle.

Is stock (KDX) exhaust a possibility for bolting up? Thats the one designed for a wide usable power band.

 

[andy johnson]

going to try a stock silencer today , see what that does.

Pretty sure 'cheep meant the stock expansion chamber and not the silencer- that'd be the route I'd try as well; I was *amazed* at the power delivery of my stock setup.
