Hi y'all, again
The clacking can continue while the engine is running for up to 1.5 miles. Most annoying.
Now on the first start of the day leaning the bike to the right definately prevents the clacking.
Starting the bike upright gets the clack. Switching off and leaning it and restarting, no clack.
It doesn't need much of a lean so I'll live with it until it stops.
I might chat to Watsonians and see what they have to say.
Cheers, Shappers.
