Thanks motorgeek. Your seeing the same thing then. I use the needle jet / main jet combo that flows correct and are happy. IMO, the problem with keeping the unhappy setup is your MJ adjustment isn't consistent anymore. Up to the range they fell out of love (500mj ?) your mj adjustment would flow just what your looking for.. 10% bigger main gave you 10% more fuel. With a unhappy setup that 10% more MJ may only give you 3% more fuel or less. That can be problematic when your looking to make a jet change and it's a crap shoot what your MJ may flow.

I use a "fit" needle setup on VM's to hold the needle in the center of the needle jet. That way they don't bounce and shake like factory fit. Helps smooths fuel flow through the range. Then cut needles as needed
