RPMs?

(1/5) > >>

raredesign:
Anyone ever dyno or tach the KX5 to see what the top RPM is?

stewart:
yes peak horse power is between  6900 and 7100  but the moter  will turn to about 10200 rpm is the highest  iv seen on mine on dyno

raredesign:
Ok, thanks...
Reason I ask, is cause I saw this one that dyno'd at 13,800 but that seemed a little high. I didn't know if running a lighter piston etc makes the difference.

alan:
I'm not sure if I would want to sit on it at 13,800! You could get a rude surprise! :lol: :lol: :lol: :-o :-o

BigGreenMachine:
Just how high of RPM's can a KX500 survive? Reason I ask is because I want to get the Turbo crank mod which is just cutting the crank halves edge to look like a pinion gears teeth. Idea behind it is to create more turbulence inside to get a better mixture/burn therefore creating power. Don't want to do so if the motor won't last.
