I have three other bikes and don't have half the trouble from them all together as I get with this one and none of them are what you would call "young" nor were any of them half as expensive to buy, in fact the G12 cost more than the other three put together with change.
I was not intending to rebuild the bike for a few years but it looks like I may have to just to get it to run properly.
I am interested in your comment about the clutch, I noticed when I took off the chaincase inspection plugs while it was running that the clutch is running a bit out of true, did the clutch coming off cause any other damage at the time?
