Shindaiwa/Tanaka Throttle Lever

It should work fine....you mount it on the handlebar, inboard of the brake lever if your using one on the right-hand side. That would be before the brake, next to your grip.

I'm not familiar with that particular lever, but the levers that came on the BladeZ scooters that had Tanakas on them, had a bit smaller end on them than a standard brake cable. Nothing that couldn't be remedied with a file and/or a Dremel tool, and a steady hand.

im sure it will work fine a atv thumb throttle could work also
