Max power is quoted at 6,000 rpm so don't see any reason to exceed this.  My Silk feels very "busy" much over 4000 rpm but this may be me as I am more use to 4 stroke singles! The porting on mine gives a definite surge in power  about 4500 rpm which is slightly variable with ignition timing.  I rarely go much over 5000 rpm. I have a 17 tooth gearbox sprocket fitted which results in 4000 rpm giving a speed of just over 60mph.  The small sprocket helps with pulling away from standstill but not very relaxed cruising.  In my opinion I'm not sure why anyone would want to thrash a 40 plus year old bike with limited spares availability - there are other bikes with good spares availabilty for that.  I just enjoy the light weight, good handling and riding something a bit special but not especially fast.
