Idle speed

Good day all Bike is running well but just lately it's been a bit cough stall in tricky slow sections fitted a new plug not sure it's helped I'm thinking it may help if I could raise the tickover but not sure how anyone have any ideas?..my ktm has adjustment on the cold start but obviously there is not one on the yam

There is one. It's on the left front of the throttle body. A plastic Philips head screw. Turn it anti-clockwise to increase idle speed.
Be careful not to turn it too far. I did, and the screw fell out. Another visit to the spares counter!

Ah thanks I will get in there & have a look..
