1) Throttle cable snagging somewhere, or, more likely
2) air leak when warm (inlet manifold; exhaust gasket; head gasket; crank seals)

Hi Bofs, I had used the wrong gasket sealant, i used the red hermatite stuff and not the Blue high temp silicone sealant.

All i know is that it's done the trick, although the cylinder bolts could have been a bit tighter!
