Re: nc 30 carb balancing vacum points
The only one I had trouble locating was on cylinder #4 (front right) as it seems to be in a diff position but from memory it's the easiest to get to. To be safe I'd make sure you screw your adapters in when the engine is cold and let it cool thoroughly before you remove them or you can end up stripping the tread and then you'll be in a whole world of shite.

Re: nc 30 carb balancing vacum points
Agree with neosophist....it should be near/behind the thermostat unit (did my NC35 recently, I found it after a few minutes of searching
) PS: Have you got a haynes manual?

Re: nc 30 carb balancing vacum points
It will be best to balance the carbs in the setup that the bike will be run in (airbox on etc).big cheese wrote:nice one guys found it can get on with the balencing now thanks again ,does it matter weather the air box is on or off and the plate that holds the trumpets is there any tips as to how to get that on to the carbs nice and easy,
Getting the carb top plate on can be a pain. It helps to loosen the screws that hold the 4 carbs together (on the ends) so you can jiggle them a round a bit.

Re: nc 30 carb balancing vacum points
I did that too. Seemed logical to remove it... at the time...
