I'll have to give this a try.
As for adjustments et'c. It's new Clutch Cable, was working fine after it was replaced approx 5000+ miles back.
New Chain and sprockets so all adjusted to book specs.
Might try an oil swap but it's the same oil I use in all my bikes Halfrauds 10W/40 4/stroke bike oil.
all in all this is a new development. It used to do this once in a blue moon but now it seems every time I ride I need to beat it into gear. I really need to take more notice if it eases once the engine is warm.
thanks for the suggestions.
