I have had two separate problems with the grips. The first was on the VFR on the left side and it started to peel up and I could never get it to stick again so I talked with some in the pits during a track day and I was informed that once that happens the piece is done, just put on a new one. So that’s what I did and problem solved.
Kruzin, silicone does not have the sticking power to hold the grip and that crap is really hard to get off if you ever go to put a new grip on.
On the TZ the problem was on the left side again but the grip was separating from the adhesive piece that sticks to the tank. The black grip part is glued to a clear piece that has the adhesive on the one side to stick to the tank. It separated about a half inch and was going to keep separating if I didn’t do something. I re-attached the black grip to the clear piece with superglue and it hasn’t separated since.
I made damn sure all the superglue was wiped off the tank and the top of the grip.
So if the grip is separating from the tank you will have to put on a new piece. I buy the blank sheets and cut my own grips. It was a few dollars less and myself and others seem to have good luck with that method. Also, make damn sure the tank is clean were the grips go down. I cleaned mine with some soap and water first, dried it then wiped it down with rubbing alcohol a few times then took a micro fiber cloth and windex wiped the tank off again. Squeaky clean and the grips hang on!
Also, remember, it helps if the tank is warm so I put them on in the sun and let the grips get warm and the tank get warm. Let it the bike sit in the sun for a bit then put it away and didnt use the grips for 24 hours. I want to say that is part of the directions if memory serves.
