97 GP1200 No Oil on #2

[dsteinmann]

JUst bought this 97 GP1200 Compression in two outter cylinders is 110 middle was about 50.
Next i looked at the oil lines

Looks like two Are disconnected / Only the flywheel is hooked up I guess this is the only place it injects oil

So I Guess it suck it through the crabs only??
The two good clyinder look great can still see the Crosshatch. The MIddle one the rings are seized to the piston and a few groves in the wall not really bad? What do you think?

So It looks like the the Crank is dry on that cylinder also the bottom bearing seems fine no side to side play more than the rest

What you think I should do?????
Replace oil lines and longer
New #2 piston rings and bearings kit

What about the wall? Could i buy a used stock sleeve (no machineing

Could I just hone that cylinder, used stock piston and bearing and re ring all 3

Personally... I would buy a new piston, and rings, and just replace it. (hit the cyl with a quick hone) Then... verify that all the oil lines are hooked up, and working. I would also put a little oil in the fuel for a tank or two.

The reason I wouldn't do more than that... is you want to find out if the rod or crank bearings are going to give up. If they hold for a tank or two... you are OK. If they are damaged... they will give up quick. But, I have a feeling you found it before any real damage happened.

awesome thats what i was wanting to hear. I figured id be able to tell in 20 minutes or so if that crank is going to be ok.
Think I should do the other rings?

I was going to say no... but I just noticed that you were down to 110 psi. That engine should be around 125~130. So... sure... they aren't expensive, and they will bring back the compression.

Needless to say... put some oil down in the crank before putting it back together.
