I just got a new quad and it has a twist throttle with a Keihen 34mm carb on it. Does anybody know what I would have to do to switch this from a twist throttle back to a thumb throttle. I was just out riding at the track and I dont really like the feel of the twist throttle and I want a thumb one again. Any ideas on how much this would cost. I gotta figure the only difference is the cable and the assembly at the handlebars. So can I just put the old one back on even though it is a different carb(if it helps it came stock with a mikuni 26mm). Oh and also the TORS has been disconnected and removed.
