This is the one I installed:Which one did you pick up?
Buy Motion Pro 01-0092 Throttle Sleeve: Throttles - Amazon.com ✓ FREE DELIVERY possible on eligible purchases
It took a little elbow grease to sand it down a smidge so the throttle returned properly. The one I had seemed to bind of a little inside the throttle cable housing. Once she returns just fine, I hit it with a light coat of flat black paint (since the actual product is white) and slapped on a new grip.
You'd never know I had a quick turn throttle just by looking at it.
