ON THE FREE HUB INJECTOR.....the FHB allows injecting a MINIMAL of real slippery stuff eg very light synthetic. IMHO never having used one hehehhehhe.

haven't done a VERY LIGHT SYNTHETIC search for years so get to it....an interesting cyberjourney from Galactic Sperm Oil to the top off Finish Line Red. Aircraft to drag racers to F1. The Wright Bro remeber ?

where is a small displacement hi output motor used in short duration lives? What could be used to thin Valvo or Castrol synthetic 2 stroke oil ? Gnaw not slippery enough...what does Yamaha use in 2F1 ? Or the Shrink Bro ?

Ibain blending gasoline with some success. No doubt possible here in oil...ask your friends. Tellum abt your your garage sale .....http://www.toonopedia.com/gyro.jpg

off course once the hub goes noisy then you need a new hub. a new set of Mil Spec G5's ?
