I did not remove the original rubber Honda grips. I just clamped the ISO over the original set. I made sure the tapered end of the rubber sleeve faced inwards as per instructions.

After installation, I noticed that the throttle was 'sticking' and not returning to 'original' position. I thought this was rather strange and potentially dangerous! When I uninstall the ISO grips, the throttle action was back to normal.

i don't understand the reason why but it seems to me that once the throttle is clamped too tightly on the F6B, after twisting the throttle and letting go, the throttle doesn't want to close!

Please advise me on whether this is normal or not?
