Installed new grips on a new bar today. The clutch side seemed pretty tight. I was up at the house,(not in the shop, really nasty weather here), so put the kettle on. Poured boiling hot water in a bowl and tossed the grip in. After a few minutes, pulled it out, shook off the excess water, and it slid on easily. In a few minutes, cooled down, totally dry and really on there!
Needed to trim and smooth the throttle tube (old single cable style). Just finished it up the same way and went on in seconds. The grips are very soft and expand when hot.....
