    Measured it up as best I could and it is approx 25mm OD with a 21mm id which seems to match that Motion Pro tool.
    I can get one on eBay for $28 and some change... might just grab that and then I have one...

    Special socket arrived yesterday and made it super easy to get the Centrifugal filter off... clutch pack looks ok but I will need to measure it up. Interior looks to be nice and clean really.. hopefully all the gears and output shaft are fine.
    Hopefully I will be sand blasting bits like the bash plate and chain guards etc on the weekend.
    When does daylight saving start again??? Oct 4th cant come quick enough for me...

    Hmm seems that somebody has been in the engine before... there should have been a circlip holding the clutch pack onto the shaft... not there on this one, I wonder what else will be missing lol

    Frame was back from the blaster last week and immediately wiped down and then Etch Primed... the I dug out most of the bits that need to be blasted (forgot the air box though) and had a heap of fun (not) with the blast cabinet.
    So swing arm, bash plate, chain guides, side stand, footrest bracket and the top triple all had their turn on the blast cabinet today... I only have glass bead and it is pretty much past it now so it took quite a while..
    Happy with the results.. everything other that the top triple has been etch primed and will have a couple of coats of Eastwood Satin Chassis black (2K).

    This is how most of the bits started out...

    I also finished splitting the cases and the gears have all their own teeth plus the output shaft seems to be in pretty good condition as well... everything just needs a good clean (read time consuming), new bearings and seals in the gearbox and a rebore or even a new barrel and piston (probably cheaper than a rebore and new piston to be honest).
    I am surprised there wasnt more damage inside... what with the sloppy cam chain, no retaining circlip on the clutch and a bent nail to retain the chain tensioner guide in place of an E-clip. Obviously they lost the E-clip and it was easier to drill a hole and insert a bent nail... WTF.

    Don't forget to put those funny shaped washers back into the fork pinch bolts of the top fork clamp as without them there is a big chance of snapping the alloy casting.

    Yep... the D washers are put to one side... with all the bits for plating.
