My good friend asked me to give his C240 a service, so as the weather was good I did it today. (Got the parts over the weekend from those good people at GSF) Got to say changing the plugs was exhausting. 12 of the blighters! and 6 of them you can actually see. Tried a few combinations of wrenches and attachments until I found one that worked. Plug socket (3\8), 3" extension (3\8), adaptor 3\8 - 1\2, and a ratchet. Perfect. Had to remove all coils, and move away the washer tank and airfilter top. Managed without removing the intake ducting though. Along with some fresh oil and filters, nip up a wheel bearing, fix the squeaky sterring damper, replace 10w tail light bulbs with 5s (one socket was melting?) and all was well purring like a nice V6. :bannana: Thanks for the help (you know who you are) ps. gratuitous shot of the bike too.
