i would try retarding the timming back to 32-34.put a white stripe on 1 tire and have someone watch the stripe on take off to see if you have a lot or a little tire spin. my 2 cents

This....but instead, get someone to video the tire with the stripe. that way, you can go back and slow it down so you can really see the tire spin.
