I really like my BUSA grips. I didn't use the alcohol like the directions said to. The left one was easy, I cleaned the bar off really good and then sprayed hair spray onto the bar. Then slid the grip right on. The throttle was a little more involved. I removed the old grip and then trimmed the outer ring on the throttle. Once I had that trimmed up and even, I sprayed that with hair spray and then I tapped it on with a dead blow mallet. Took about 4 taps and it was all the way on. I tapped that one on because I was not going to be able to twist and move that one around if it wasn't straight. That is my .02. Hope it helps.
