Powervalve timing

Next time I will.... I need to start verifying these folks actually have parts in hand in stock in their store/warehouse....

eric,

If you did the mod to the '00, and it had an old FMF Gnarly pipe, I suspect the pipe had a lot to do with it, and perhaps the older ignition. They put everything on the bottom. From what is reported the head mod is great on the new 300s, and I can say for sure on the 250s. The new bikes rev out more than the old XCs.

A few mm of slop should be adjusted out.

So it sounds like you lost some of that sewing machine smoothness of the motor? That is what I bought the GG for, the KTM 300 is just raw grunt!

I have gone the route of the head mod on my 300 and, frankly, it seems to make the bike a bit "chuggy" like the KTM. He does not want that. Does anyone know if that lack of resistance would make the bottom soft just off of idle? Thanks for your help!

Too bad widebear got banned, he ws working on raising the cyl for more mid/top port timing in conjunction with a squish/compression correction. Seems like this may end up like a big bad 250.

Send me a PM with what gaskets you need - I stock multiples for just this very reason.

Will do next time.
I should be riding today and I'm not, because of gaskets.
That's just wrong.
