Hi

The restriction is in the exhaust. The ATAC chamber (on the side of the barrel) on full power bikes opens and closes depending on rpm. At high rpm it would be closed and open at low rpm.

All the best

Hi

Have you got the right mix of water and anti freeze? Does the water pump work? Are the radiator fins in reasonable condition? Is it using coolant? Has the ignition timing slipped?

All the best
