When adjusting the valves on a friend's 1100GS, I noticed that the two lower rocker cover bolts on the left hand cover offered little or no resistance when being removed. When we removed the cover, I found this. This is the bottom right hand corner of the cylinder head - the aluminium casting has broken off (possibly due to an over-zealous previous owner).
I have removed the head, with a view to getting the offending area 'built up' with aluminium weld and then re-tapped.
The bottom left hand casting is stripped of all thread, so I am guessing that maybe a heli-coil will fix this ? - or am I wrong ?
Main question is - Does anyone know if it possible to repair the head as suggested above, or will it need replacing ?. I really don't want to have to replace the head and transfer over al the valves, rockers, cam etc if at all avoidable.
Any advice would be greatly appreciated.
Thanks
