Strange spark plug wear?
Replaced my spark plug today. I also checked the tightness of the exhaust fittings (headers and clip connecting downpipes to exhaust ) - these were very loose, which would explain some difficulty I have been having with starting it without full choke, even in summer .
The condition of the spark plug seems rather strange to me. I last changed it between 5-8,000 km ago - can't remember for sure. What do you think from these photos?
