Having an issue with my AR, it runs fine apart from when I'm slowing down with the throttle closed, the bike surges as if I'm slightly blipping the throttle. It also does this on tick over, it doesn't stall but the revs rise and fall slightly as if it's hunting.
Not sure if it's carb related or if it's more of an electrical issue? Any advise would be appreciated.

Sounds more like a carb issue. Strip and clean every bit. ARs are buggers for these kind of small problems when something gets part blocked or a sensor goes a little off.

A Mk1 or Mk3 every time ................

mine hunts all the time at idle too
always has

Stripped the carb down, checked and cleaned the jets, all ok. Found a pipe not connected on the far side of the carb which goes to an electrical connection with a dark red spigot, reconnected and it wont start at all now !
Took carb off again checked everything, put back on and still won't fire, what have I done ??!!!

Now sorted, left it overnight (possibly flooded) checked everything and it's now started ok. Runs a bit better as well so panic over!
