okay so i just got back from the dunes and this was the first time on the dunes with my banshee. Everything was great with it except for shifting. It would shift through 1-4 gears no problem but when i wanted to go into 5th and 6th it wouldnt shift when i was in high rpms i had to let them get low. This only happens on the sand dunes when i trail ride and everything it will go through all the gears with no issue. Could it be the shift star needs adjusting? Btw i have a banshee with fmf fattys powercore 2 silencers and skat track hauler paddles and a boost bottle (and i know boost bottles can crack intakes and everything just waiting for jets to come in that i purchased online so i can switch back to a stock crossover). Any help will be appreciated.
