Just now starting to set up my new/old 1980 G5 for daily riding. It was suppozed to be a display unit with 10, yes 10 miles on it! I haven't looked into the engine of this time machine yet but some things are kinda intreresting.

Everything on this bike seems to be unmolested for 30 years. I'm hesitatnt to be the one to molest it but I sure don't wanna destroy it by starting it up and having a 30 year old bearing sieze...

One is the battery. It's dry but not corodded. hmmm The plugs looked like the bike ran a little so maybe the battery IS original.
Kinda cool in a museum sorta way... if you like that sorta thing.

My guess is that this thing is gunna require every seal, and most bearings.
 
Other will chime in that will know, but if it has chrome cylinder bores then Don't even consider starting it up. I still would like to be in your situation, nice find !!!!!!!!

Ditch the battery, did the motor have oil in it and how does it look ?
Seals for sure but still don't see a reason to consider the bearings as in need of replacement. Does it turn over freely by hand with the plugs out ?
 
G5s never had chrome bores. Iron, and maybe nikasil at the end of the run.
 
My experience with a little-used 25k mile bike is that every rubber component and seal will probably need replacing, and probably the shift return spring once you get to about 30k. And if it's got iron bores and not been turned over there could be a line of corrosion where the rings were sitting so it'd probably pay to pull the heads to check that and the valve seats. Maybe Pete Roper can do the PD while he's over there? ;)

I'm also wondering how the main bearings liked the crank siting in one spot for 30 years.

What's a PD?

I love finding old timey stuff like this. When I was restoring this '46 Commonwealth Skyranger, I took off some upholstery panels and found where someone had decided that this door fit better on serial number 29.. :lol: Needless to say, I left it there.

Wow Chuck a '46 SkyRanger. That makes our '56 Cessna 172 look absolutely modern in comparison!

:D

But we didn't do any of the actual work on it ourselves. After trying for far too long to buff out the original unpainted aluminum, we had it painted.

I'm just happy I can fly it.
