    Hmmm... the scary part is that you and @Linkin might be right :oops:. I did have red coolant leaking from the front of the head gasket though. I have read that that red coolant can cause corrosion in head gaskets on engines which are not all alloy (such as the triple engine). Anyway, after this job, I can do anything! :drinks:

    Well, waiting on a couple of shims for this head, should have them Monday. Replaced all the rubbers on the idle control air hoses. Hoses were still very good, but the end bits of hoses where all kaput. I blew into one of the hoses, and what do you know, it made lovely whistling sound, very much like the noise I was hearing before :mad::headbang:. Anyway, hoping all will be running on Monday....

    Replaced head, head gasket, did complete valve clearances with revised shims, and fixed air leaks (as shown above) - verdict? IT LIVES!!

    And now, it feels like a new bike... never gone so good, it flies like the wind, and no niggly grumbles below 3,000 rpm - just smooth power all the way!!! Yee Haa :minigun:. You can hear how the idle is consistent and smooth - never did that before!
