Im a bit lost, Ive just finished rebuilding my carbs, I balanced them and have been trying to fine tune a good idle with the mixture screw. I put the airbox back on to do this and all was fine until I realise I hadn't connected the crankcase breather onto the right side of the airbox. As soon as I did the engine died and wouldnt start again. I unplugged it and the bike ran again, plugged back on and it died again within about 3 seconds.
Does anyone have any ideas Im a little lost.
