Got a nice lightly used Pitster Pro 125 HO with the V2 head. I have a Mikuni VM 26 606 that came with another quad I picked up. What is a good jetting starting point for the midwest. I live around St Louis Mo. Right now it has a 145 main and 15 pilot. Terry says to start at 150 main and 20 pilot. Also running 110 octane. Ordered some unifilters but would like to run the airbox if possible.

You're wasting money by running race fuel. Use 93 and see how the bike performs with what you have. You're not far off from what Terry recommended.
