Thanks for the info, I am planning on setting from the plug color, just wanted to make sure I am starting from a safe point, didn't want to rebuild a new motor that I am just putting in.
THE LADY FROM CRANK SHOP WAS NOT MUCH HELP, THIS IS WHAT SHE SAID, (What I have is for twin pipes at 6000' to start with a 440 main jet on the 800 rmk/xc Usually with our pipes we suggest jetting up 2 sizes from stock and test from there). MY ELEVATION IS 2175, THERE IS A HOLTZMAN ON IT...
