Sorry ,I wasn't clear. What I,'m thinking of doing is to swap pistons and barrels with new rings today, run it in with the holes coverd ,Then put a pair of Swarbrick cans & open the holes at the dyno.Then go to Brands
One more question ,how is it best to run a set if rings in ?
Sorry about these questions but I realy don't want to sieze the thing again.
Many thanks
