First round of the VMX yesterday. The Bighorn foot peg broke off in the practice, lucky I found a farmer down the road with a welder. So a DNS for the first race. I've been having a lot of trouble with the off idle to approx 1/8 ish throttle. I made some last minute change's to the program the night before ( not tested ). What a difference! Easily the fastest in a straight line in pre 75, and pulls so much better than it ever has from the bottom of the rev's through to 8600. Still might need a little more advance down low or perhaps a little more compression or perhaps just some new rings. Gearbox is standard F9, so having a wide power spread is a good thing. F81M close ratio gearbox would be nice to have but they are almost unobtainium now. I will look at making some gears up, is anyone else interested in an F81M gearbox? If I find some pictures of the racing I'll post them.
