I've been running my bike with Gunk Lead Substitute since I got it running..... Just wondering if anyone else does? Does it really need it? I know back when these bikes were manufactured most gas was leaded. The owners manual states use 91 octaine leaded gas. Newer engines have valves that are made of different medals and some have soft seals that are designed to be used with unleaded gas. Would running unleaded gas with no substitute cause premature valve damage?
What's ya'lls input on this?
