Hi Peoples I have been riding a little Kawasaki KH100 for over 2 years with a problem that no one knows the answer to. I have tried other forums but nothing has worked so I trying one last time. The bike starts first kick every time, will tick over lovely all day long and is as reliable as they come. The bikes engine sounds great no nasty noises. Now the problem once you get to 7000 revs it has no more power it still revs to 9000 but just has no guts and can only get 45 to 50mph. I have just built another bike with the same engine and this goes like stink in comparison. It seems and feels like the problem bike has no powerband. The bike has been re bored, up jetted, exhaust de coked, carb cleaned and new plug. I have changed the points and condenser to another used unit, changed the ignition coil. Its seems to me that since I tried the other bike that its the powerband area it just doesn't have one that's where my problem lies. Any ideas peoples
