So my issue I'm having with my Tomos (99 TTLX, with the A35, 70cc Alukit, Techno Estoril, stock carb with high flow filter, 71 jet) is it runs perfect all through the rpm range, shifts fine with only a little 4 stroking (break in period), but as soon as it winds up in second gear and reaches about 45, it bucks and feels like it simply cuts out. It starts slowing down, and no matter what throttle position I move it to, I may only get a few pops out of it until it slows to about 35-40. It did this before with stock everything, biturbo and a 54 jet. Ideas?
I'm not sure if this thing is restricted in some way, but it's kinda annoying. Thanks for the advice.
