CB500 K1 Rebuild
Charlie J:
So, following some gratefully received advice from BryanJ, I’m going with a 550 cylinder block with a 0.5mm oversize rebore. Not only did Bryan help me out with his expertise, he also offered to do the rebore for me. How good is that!
Whilst waiting for the rebore to be done, I took the sump cover off to have a look at the primary drive chain. As can be seen from the photo, any hopes of good news soon disappeared.

The chain has a huge amount of free play and has been chewing its way through the crankcase.
Just got the cases split after whacking with a rubber mallet for 10 minutes before I discovered the ‘secret’ bolt in the sump area! Next job is to take a look at the crank bearings, but following my discoveries so far, I’m not too optimistic about them being in good shape. Oh well, all part of the fun as they say.
Charlie J:
I’ve also learned how to nail a cup of coffee to the ceiling :)

That looks quie clean in there so bearings could well be OK. Remember to keep the shells where they came from as you will not be able to identify the size if you mix them up
Charlie J:
Thanks Bryan
Will do.
