Thank you for all that answered. I think I am right there. I looked into it and I am on a 168 main, the JD red top needle in the middle position, and I have a 58 pilot. My fuel screw is 1.5 turns out. I took off the plug after some shredding of the yard and it looks right. Slightly tan, not wet and no dark spots. It idles nice and makes the power. I was just expecting the 250 chrisp-ness, but I guess these aren't that way.
I have this in a 2001 RM250 steel frame chassis and I am using a CR500 DEP pipe. The pipe might throw things off a bit. I have a Wiseco in it, and Eric Gorr ported and epoxy pored my ports. It seems nice and smooth. I guess I have to check it out some more after a day of riding.
Thank you.
