09 250 low altitude jetting

[yz dude]

no squish yet...i'll prob have that done when the snow gets here toward the end of the month.

have any of you gone ahead and had the cylinder ported as well?  if so, is it worth doing?

There are a few on here who have. I have not. But those who have generally report better overall power, extending it throughout the full RPM range. We seem to be able to do the same thing with proper jetting, but maybe have overall less power. I don't know enough about this to really say one way or the other.

Thanks so much for the jetting suggestions, 45pj & 170mj was the ticket!!! Ran Super M 40:1 w/race fuel. Bike ran like a scalded dog, i didnt do quite as well;((

Glad the bike ran well. The Zink Ranch enduro is on my list of races I really want to try.

i highly recommend it, it was a great time and the course was a lot of fun!  the rain we got the night before didn't help much but at least it wasn't dusty:))
