Yet another mikuni carb question

[tonytiger]

What is the best groove setting on the needle, my steamer idles at 3000rpm

[tonytiger]

Or could it be the k&n filter I've fitted do I need to rejet it.?

 Someone intelligent will be along to help shortly.

The only thing I know is the best groove setting on a needle is 33 1/3 rpm.

Won't make a huge difference, just make sure all the intake joints are as tight as a duck's 

[tonytiger]

Thanks, when it was running I sprayed some brake cleaner on the rubbers, it made
no difference to the engine speed. I'll look again at the weekend.

[tonytiger]

Thanks nick took a while to sink in

[JayDub]

are the carbs balanced?
is the throttle cable seated and adjusted correctly at the carbs?

[Sin_Tiger]

One last thing to check, however unlikely it might seem, is that all the choke mechanisms are properly seated. It's not difficult to nudge one out of alignment so that you have permanent choke.

[tonytiger]

Thanks JD & sin I'll check this weekend and let you know.

Just took carbs of again, checked carbs by eye 1 carb was out of sync.
Adjusted put back on bike runs fine.
must buy new gauges and then seal tank - then job done

Nope, it'll be replaced by Scottish Whisky at exorbitant prices since our EU sales will suffer
