Reply To: Valve clearance, camshaft, camshaft tensioner – a problem or a serious fault?
Hi, I received a 13T sprocket, so I will be experimenting with gear ratios to find the optimum one for me. The rear sprocket has 52 teeth, supposedly for the 428 kit.
I sealed the entire system step by step, just as you described. I used new clamps everywhere, which were narrower than the standard ones (they did not push out the carburettors or stick into the intake manifolds).
The previous clamps were wider and I couldn’t fit the carburettors precisely onto the intake manifolds, and ultimately the carburettors popped out of the rubber.
I encountered a problem after the last carburettor adjustment.
Namely, regardless of whether the motorbike is warm or cold, it chokes when starting in first gear and in every other gear if I am at low revs (below 3k rpm).
And now I don’t know what to do, because when I rev it up, I can smell unburned petrol in the exhaust fumes. Could this be a further problem with the carburettor adjustment? It turned out that the jets are set to 90 and 92.5. But I don’t know if they are mixed up? I don’t know if I should take the carburettors apart and check what’s going on inside them? Could it be that the needles are set incorrectly?
There are a lot of guesses and I don’t know what to do at the moment.
