jammin crt.5 motor suggestions

temps were still great @ 18/46

anyone have a suggestion on how to get rid of the cogging i get when i start(only when i go full throttle)

i tried to adjust different things and didnt seem to help much

seems to be faster now though, it will wheelie and such, probably about 27-30 id guess, goes good though the front tires balloon like crazy

i think a 3s pack would be perfect
