2010 ktm 250sx feels too tame

Recommended Posts

Hey i recently bought a ktm 250sx and I have noticed it doesnt have the crazy hit i feel when ive ridden 125s and im wondering if it could be that it has a platinum 2 pipe, or if it needs a powervalve cleaning, if its the ladder.  How the heck do you get to this powervalve, im used to snowmobile ones that you just pop out with two bolts.

The power valve tuning may be really soft. There is lots of info both here and elsewhere on how to tune it. I run the red spring, 2 turns in from flush for a truly healthy hit.

Also clogged/impacted pipe and silencer...

Turn the powervalve preload spring all of the way out, the colored spring IMO doesn't have as much affect as the preload spring.

Also, pull the head and check the x-dim.  It is likely that a previous owner put a piston in it and didn't take care to set it correctly resulting in low compression.
