Not too long ago, it seems, there were advertisements in the back of the snomo mags about an inexpensive device which attached to your existing thumb throttle and allowed it to be operated by two fingers. The thumb throttle remained operable, but you could also use your fingers.
I can find stuff about the patent online, but can't find the device for sale.
man i would love to find that also i thought i was just crazy i have a 98 fromula 670 and my hand makes about 50 miles and thats it i start to cramp and my buddy has a 99 mxz 670 ho and his is way worse than mine if you find on please post it thank
Got mine at sled show. Works great but be careful. Glove can get wedged between throttle and bar leaving throttle stuck open. Also mine had a small burr on it making the throttle idol a little higher which on my 4 stroke the computor would cut the engine out.
