As it happens, not too much has happened so far, since I´ve been spending my time on the downdraught heads for the HYM1100 motor. Right now, that project is at a point where some investigation is needed to decide where to go, so I´ve decided to tear down the M800 motor and start with an external clean-up. Since it will be a complete overhaulc with bearings etc, I want the motor to look pretty on the outside as well.

Also. the cylinder heads will need some attenton, since some of the plastic filler has started to lift at the edges, not sure what to do there, but some porting work will certainly be needed. It may not show too well in this pic, but it´s there ....

So, that´s it for now. Not too exciting :-)
