For many years now we have been racing and motorcycles have an easy tool a chassis dyno - in using it for 25 years you come to understand and see things that make power NOTE : ( In the speed that a unit will make power and having computors today laying them over each other ) Grafts are a neat tool --- making one change at a time using a MULE motor in a bike will show you things, before doing it you would not believe -

Syn oil not all but select product, can and does make power you can see live on a dyno -- if you need more into i can provide --

Mobil 1 Royal Purple Red Line are a few that do just that < jz
