thats what I used, spray on glue. I've heard you could use hair spray also, but my wife doesn't use the "Aqua Net" aerosol type so I found a can of spray glue. works great, i'll just never be able to swap out the grip on the throttle. though most of the time you have to buy the whole throttle assembly together, grip and all so,!!! I couldn't take the way the grip would slip when trying to ride. bad enough having to fight the governor, but fighting the grip also, losing battle so I glued the thing on. now when I floor it, the throttle doesn't slip back against the sleeve!
