i have got a edlebrock fitted to my polaris predator with thumb throttle seems to be running fine with good throttle response but i need bigger throttle muscle for my thumb its bearable for motocross and short periods but whant to use the bike for endurance racing for a few hours or so it uses a suzuki thumb throttle and a bit to stiff for me does anyone no of a different thumb throttle to make the action lighter even it is a slower action it will be fine as you get more throttle response you dont need such a quick action.any suggestion would be helpfull.

 

I would like to know the same thing. My thumb kills after a long ride.

 

sounds like you guys sure could use the thumb throttle extender. you can use your whole thumb and even part of your palm. i have one on my scrambler, and it makes the long haul alot nicer. cheap comfort for 20 bucks. check it out. you can get em from just about anywhere.

I second that! Extenders are well worth the $$$.[img]i/expressions/face-icon-small-happy.gif[/img]
I got mine from Rocky Mountain ATV!

 

Take the return spring out of the thumb throttle....It will help alot!!! [img]i/expressions/face-icon-small-wink.gif[/img]
