Hi all.
I have a '74 MK 11 A 850 Commando. Noticed it getting bit harder to start recently .
Until the other day had no spark at all and wouldnt start.
Pulled out plugs and replaced with new.
Started fine.
The plugs were only in the bike a few months and are now useless.
The electrodes are black in colour and are what i would describe as 'sooty'.
What is the cause of this and how do i prevent it happening .
I run a single mikuni carb .
