Because these bikes used leaded fuel,can you burn a valve if you dont use some sort of additive.And what do most folks do. Thanks mike

Unleaded fuel.

I've been running a CL77 for around eight years and CB77 for a year, both on unleaded fuel as it's hard to find leaded fuel here in the UK

No problems with either. Early engines ran a slightly higher Comp ratio which might be more of a problem but I'm sure you'll be OK. (My CB has the 'high' comp pistons fitted.

Just keep an eye on exh. valve clearances and investigate any rapid changes.
