So, as some of you may know I recently revived a m600 after 6 years hibernation for a friend of mine. He says it's running 'strange and revs keep dropping' my guess is dodgy fuel from the bottom of tank or spark plugs(ones I ordered for first time rounddidn't fit). Question is if it's plugs where do I get them on a Sunday. I'm in Southampton if anyone knows somewhere close. I'm taking it for a good blast in morning to see if it clears.
