thanks for the throttle tips guys, as of now i doubt it's the cold (bike is inside right now) I did drip a few drops of my chain lube into the tube (it's all I got) but right now i am glaring in an accusatory fashion at the grip handle itself. that handle barely fits together, lots of play. all plastic. i might just put a heaver spring inside the carb for now, but i have already put that twist-grip on the list of things i need to replace. probably worth mentioning that the carb is on that list as well.
