Thanks Dave and Simon,
It starts first kick, idles fine and runs nicely so I will leave alone for the moment. Is the 276 a bigger bore?
As I get to know the bike a little better I will find out more. You never know it might have a different cam in it already.
Only thing that requires attention at the moment is the charging. I have been told it was fine but on the test run it wasn't charging. The regulator is supposed to be an electronic one but I have yet to check that out. I will check the Dynamo output...........................what is the best way?
Battery is past its best so will replace that to.
