When should I optimize the carburetor settings of the motorcycle for better performance, is it immediately after starting or after engine got heated?
Problem which I am facing is:
1. When I change the settings when engine is heated then it will turn off imminently in cold start while switching to first gear.
2. When I change the settings in cold start to avoid turning off on first gear, then the engine idling RPM will increase so much the it will cross 3K and will come down suddenly once I start releasing the clutch. This is affecting the gear shifting as I listen to the noise making by the engine to decide when to make upper shift.
Is this normal for motorcycles? Is there any fix for this?
I was initially using
15W50 engine oil and I changed it to
10W40 because of winter and the engine started to make more noise (higher RPM) because of previously tuned settings. Does engine oil types will affect the RPM?
