Took my banshee out the other day to the dunes, its a 4 mill bike with a lock up, the tranny is stock, it shifts just fine cruisin around, but if i try to drag race, it will not shift, it does not shift out of first gear under a load i guess, it wont shift 1-2, 2-3, 3-4 and so on, but it does shift fine if i am not trying to race it. Does anyone know what exactly that is and how to fix it? I dont really want to put an override in it, the bike makes about 75hp to the tires, any help would greatly be appreciated, thanks.
