Is it safe for these CB's to run on unleaded gas? OR should lead-additive be included on every fill up?
I had an old VW beetle had to do that with..

And if you use unleaded, which octane (87-89(ethl)-91)

If this has been covered, pointed to the topic thread would be appreciated.

relatively high compression ratios coupled with vintage head design require high test.. general consensus is the valves used are compatible with unleaded gas

I run regular unleaded in all of my bikes and havent had any issues. The high test surely wouldnt hurt though and the unleaded seems to be fine.
