Slow rev decrease

Food for thought isn`t it . I have left mine alone on purpose , when I fit the clamp and it cures/doesn`t cure it ...... we`ll know if I`m barking up the wrong tree

ahhh ha.

The pilot jet is sometimes changed when a more free flowing can is added, maybe your jet is the wrong size now 5short5, check they are all standard sizes.

Anyone know what the default number of turns out it is for pilot screws on the carbs? Is it 2.5?

ignore that - found it at the front of the chapter in haynes

Rarely. I have not heard of anyone changing pilot to anything but 17.5 (mikuni size) which is the stock size for UK bikes. Some US ones get 15 size.

Pilot screws between 2.5-3 turns but these will just do some crazy stuff if you have an air leak

we i had time today to have another look and after taking the carbs off and refitting them they had the same issue so I dusted of the 5 quid fleebay set and stuck them on, interesting they work rather well. I just reset the pilot screws and set the balance screw to the same as the other carbs and it's not perfect but close and a load better than the ones I had so I'll stick with these now
