    Picked up the frame bits from Linkin yesterday and home to block up all the important holes. Took to blasters today for a clean up.

    With Linkin away learning how to be a real motorcycle mechanic, I have picked up the reins on this one. Frame has been blasted and painted in two pack silver and I am now working on the engine. Valve and seats have been cut and new seals on order, ports de-burred and waiting on supplies of sanding disc to finish polishing.
    The bores are all scratched and worn at the top of the piston stroke, and new O/S piston kits on way, along with new timing chain and gasket sets. These verticle scratchings are what happens to bores when incorrect or no air filters are used.

    To get the last three bolts out so I could get the cases apart I needed to remove the rotor. An incorrect threaded bolt had been tried before and had stripped the thread. I ground the end of a tap flat so I could clean up the thread and get the rotor off (some heat from a gas bottle torch helped)

    At last they are out.

    Cases split and bearings are reasonable, but will be replaced to do the job properly.

    A lot more difficult than the CBR.

    The cases are a pain on these. Head and barrels off required to split them. Are the MC19/22 different in that regard?

    I only have the 19's, but head off, bottom case off and undo rods and push out through bores. Less tricky bolts you have to find when splitting cases too (particulary when you've not done one before and cannot read Japanese in manual).

    Thanks Kiff, I don't think it will be necessary.
    Doing a bit more on the head today. This is why you DON'T put silastic (or other silicone type sealers) into water fittings (or intake manifolds either). These fittings need O rings for seals, and I can understand using the silicone as a tempory/get home measure, but more is not better.

    Imagine if this big lump of blue poo came loose and went into your radiator, how many cooling tubes would it block? Cooked engine anybody?
    Riskys 2KR 004.JPG
    This is what it should look like. A bit of rubber grease on the seals to help them slide in and all will be good.

    Some people should not be allowed to buy tools. :lolsign:
    But I guess if they didn't then they wouldn't stuff anything up and we wouldn't have any cheap bikes to restore. :D

    Who would have thought that silicone sealer would come in so many different colours?
    The Intakes had red and blue on them. Will need some proper gaskets when I put it back together.
