Anyone running a setup like this on their YZ450F: +3mm 13:1 compression taller (more lift) cams ??? I just got mine (YFZ450 - quad) back together and I can't kick start it. It will pull/push start just fine, but I just can't get it spinning fast enough (by kicking) to have it catch. Bear in mind that my quad is not the typical YFZ quad. I converted to kickstart-only last August and have done everything I could to make it as close to the YZ450F as possible with the exception of lights (dune riding at night). Dry, it's damn close to 300lbs and runs methanol with a touch of nitro too. Is there a trick to kicking the higher pressure machines???? Anyone with experince in starting a similary large/built 4-stroke????
