I doubt my vette takes a quart of fuel when i nail it, maybe a pint, but i do understand what you're saying. I've learned this from having the accellerator pump go out on the carb in the vette and I was about 20 miles from home. Had to take off very very slow to keep it running...and damn did it suck getting passed by escorts and pinto's at red lights...ha ha. I spose I'm just used to the power the ped has already and I just want more. I doubt most people have hills like are here and I wanna be able to climb those and still hit 40+ mph dowhill. I may go for a 60 cc kit, I duno yet.
