My iso's tab for the throttle cable broke the 1st season I had them. I ended up turning my idle all the way up and limped along in 1st gear about 5 miles. I stopped at a yamaha shop and they gave me a used one off a warrior. I replaced them with more iso's because they match my pegs. No problem so far with the new one. I think i'd pack a spare of some sort if I planned a long trip tho
