I have a 1VJ XT600,unfortunatly it's developed a few cracks in the R/H crank case - in behind and around two of the bearings and one fairly long crack that runs from where the crankshaft is to the outside just beside the engine mounts for the frame.

Now I'm going to do some ringing around tomorrow to see if anyone has a complete bottom end,if so I'll just swap the R/H case over onto my bike,or use the whole thing depending on condition.
Now knowing XT600s seem to be like rocking horse poo here and TTs probably not much better....Would a TT case fit my existing L/H case? Or even a later "normal" XT600 casing?

I knew a 600 was going to be hard to find!
Everyone had XT400 or 550 parts,but no 600s.
Ended up getting a 550 casing and it'll need 4mm machined out of the top where the sleeve for the barrell comes into it.
So for $95NZ and probably $100ish for machining,I think I've come out of this alright! So here's hoping I don't find something else major in a month or so time.
