Sticking throttle

[Bixxer Bob]

Got round to sorting the sticky throttle yesterday.  First observation: the throttle cable is not PTFE lined, nor is the genuine Triumph replacement, so oiling it is a good idea.  You do not oil lined cables.

Next, once oiled, there was nothing wrong with the cable so I have a brand new spare on the shelf.  The biggest issue was the twist grip itself.  It's funny how you don't notice gradual deterioration until something brings it to your attention.  Until I had problems with tickover I hadn't really noticed the twistgrip action was a bit rough.  If you are doing yours, just be careful with the heated grip cable; it would be easy to damage it as you take the grip off.  Once off, it was a matter of cleaning the bar and the inside of the twistgrip tube.  White spirit or a bit of petrol (BE CAREFUL, petrol and electrics are not good partners) will do.   Once clean, lubricate the tube and the collar where the twistgrip fits in the switch / cable housing.  I used red rubber grease.  It only needs a light smear, don't go daft.  Too much will only gather dirt.  Finally, re-assemble.  Test to make sure nothing is sticking and you're done.
