Bonjour dear Norton-owner colleagues
I tried to install a hard-anodised slide provided by B... F...

My intention was to use a 2.5 slide cutaway instead of the current 3.5 to cure her spit-back when opening the throttle, and also to install a more resistant slide than the original zinc one.
I have too to sort out my no-tickover-when-hot issue, and I'm considering moving to a MK2 or possibly a Mikuni VM (gives you an idea of how fed-up I am) because the MK1 are too prone to wear, problems etc...

Thanks & RegardsLaurent
