    A few have asked me how to tell the difference.

    We know that the early bikes up to 2010 sometimes had leaky valve cover gaskets. The new style gaskets seemed to have cured the problem. For the DIY'rs checking their valves and wondering whether to spend $75 on a new one, here's how you tell:

    Old style on the left-just a bolt and rubber gasket. New style on right-bolt, concave washer and rubber gasket. The bolt remains unchanged but the added washer gives another .5mm of "crush" and helps prevent the gasket squishing out sideways to better seal things up. As far as I know, the actual gasket remained unchanged as well. Just remember to put a dab of silicone in the corners of the half moons for added luck.

    My 08's is leaking so I cheated. Tossed the old bolts and installed the new style without removing the valve cover. Meh, we'll see what happens.

    I've seen just those bolts listed on Ebay. I buy the Wunderlich gaskets by Athena and they don't have the bolts. Only the Stealer gives you the whole kit. Keep the bolts, replace the gasket I'm thinking. However, I reuse my gaskets and with the silicone in the corners, our bikes have never leaked.

    Reaver, thanks for the tip! I just noticed my 2010 valve cover was weeping on the left side (never been disassembled), and was wondering what was going on with it. Now I have a clue.

    Found while removing the side plastic, for reasons already discussed . . .

    OK so I'll finally update this failed attempt at cheating.

    Just did the 20K km valve check (at 30K). This valve cover with the new style bolts leaked all the way from Canada so obviously there's more to it. The original 2008 gasket was full of sealant from the factory so not for the lack of trying. The spark plug recesses had maybe 10 drops of oil in there each, (anti-seize!) so the middle gasket was leaking also. Not bad for 30K kms tho.

    So just installing new style bolts with the old gasket won't solve this leaky situation entirely.

    I'm in the jungle so lots of silicone on the old gasket was used.

    Mañana, mañana.

    :rofl

    when I ordered the gasket it was only sold as a kit with the bolts and vice versa, how did you manage to get them individually you cheap fuck?
