oh, in my post about carbs i forgot to mention i can do twist throttle set ups for aftermarket or non-tors stock carbs too. its dirt cheap, like 30 or 40 with the twist grip i think. let me do some checking on that, i do not use twist throttles on ATV's but again i come up with them a bunch do to the side work i do.
actually if you would test one of the twist throttle cables on a blaster for me i might send you the cable for free.... let me see what i have on hand.
