I was riding home last night and the throttle was ever so 'notchy' at opening. It wasn't stiff to turn (open or close) and the twistgrip closed of it's own free will. It's just the initial part of opening when it was a touch stiff. The cable free play is as per the manual (2mm)
I dismantled the handlebar assembly and everything seemed OK, no crud in there, the twistgrip moves freely (as it did when it was on. I did it all back up but still the same.
Any ideas?
