Right now my blaster is stock. I dont really have the extra cash for modifications right now.. considering i shouldnt have even bought the 4 wheeler! lol So anyway my question is about gearing. Im looking for a simple improvement for now. The blaster in stock form with the rear tires I have on it (22 inch) just seems like it doesnt have enough balls to get through 5th or 6th. It takes way to long for me.. the tires wont even come up in 1st from a roll. I am hoping just doing the rear would be enough. how much bigger are you guys going in the back to beable to row through some gears!
