"gas"


          

I need to know if I can run unleaded in my old bike. It is a 1972 Norton combat. What can I do to get it to run with this type of gas?

You should definitely run 91+ octane. The 850's can run 89.
All nortons have excellent original valve seats.
The ignition curve is the hardest thing to satisfy even with 91 octane. I run a RITA for my combat and have never looked back.....it has better curve for the combat. They are no longer made but old ones are always showing up. I fix them, so even bad ones... can soon get you going.
I've not tested the newer stuff being offered.
