Intake valve, specifically? Anyone know of any good videos showing how to detect a sticking valve?
I still have the odd cough coming through the RH carburetor at idle when the engine is fully warm.
When riding at any reasonable speed (so 2000rpm and above) there's no cough or misfire, and I've checked the vacuum on both carbs, they are equal - 12in max at idle speed of 1200rpm (vac gauge pointer wavers between 8-12in).
If a valve is sticking at idle speed, will it worsen as the engine speed increases? If so then I probably don't have a sticking valve....
