I bought a 1979 GS 1000 that, when the title arrived, said "NOT ACTUAL MILEAGE". It currently shows marginal compression in all cylinders, so I think it probably has a lot of miles on it. Can anyone here recommend a way to check on what shape the crank roller-bearings are in without splitting the cases?

GS 1000 crank

It's one of the things I love about old GSes...

... the roller-bearing crank. I just don't want to do the bore, rings, oversize pistons, and then find out the crank bearings are going, but what you say makes perfect sense. Thanks!

Before you rush to rebuild this thing. Make sure everything is in spec. In other words adjust/measure the valves etc. Many of these bikes get neglected. Simple adjustment goes a long way. I'm not saying that it doesen't need a ring job, but other factors will give low compression readings. This is especially true for valves that are out of adjustment. You might be pleasantly surprised.
I hope you're right!

I'm fussing with valve shims now, just need to get a list of what I need. The valves were all tight, so I'm hoping you right be right. The engine has a lot of rough spots; the spark plug holes could be better on some cylinders, someone broke off one of the valve cover bolts, and the electrical harness is dodgy. I think this one was not taken care of very well.
