    Look at the crankcase segment in the fiche. There are four plugs, one for each cylinder, all identical, cost $4 each from Yamaha Sports Plaza:

    part is 90338-11152-00

    These plugs usually start weeping after a couple of years. I've made it a point to get new ones whenever I change out the coolant. However, I've never seen one do more than weep a few drops at a time, so it is something that can be lived with eternally, if necessary.

    I have this same leak at the bottom bolt of the fake fins and will try to get a replacement plug tomorrow. How does the old plug come out - just pull it out? Also, will coolant come flowing out while I'm trying to get the new plug in? Any helpful hints?

    Go to this article in the tech section,
    Some Tips on Changing the 2nd Gen Coolant
    You can thread an old spark plug into the threaded insert and pull the plugs out, yes coolant will come in rapid fashion when you pull the plugs.
