Engine with 41,000 miles

[Guest]

So the bike I picked up, a 78 GS1000 has 41,000 miles on it. Runs pretty well. Not exactly sure what the previous owner had done. He had someone install an electric ignition but I'm not sure what else they did. I'm guessing I should start with the valves to see if they need adjustment?

Any other recommendations? Should I just leave it as is? I'm thinking I should check the compression on the cylinders as well.

welcome to the site. I'd recommend going through the MegaWelcome BassCliff included in his post on your other thread, you'll find his "little" website VERY useful.

He has a checklist of probably neglected maintenance that would need to be addressed ASAp. You should start there, good luck!

North of Boston?? Are you following the World Series? Keep your fingers crossed for tonight!

41k is considered "just broken in" on these engines, as long as they've seen at least some semi-regular maintenance.

Yes, checking and adjusting the valves is very important. Compression test is optional unless you suspect a problem. (Although if you already have a tester, no reason you can't check it to satisfy any lingering curiosity.)

Many of us start with a full tear-down, cleaning, and rebuild of the carbs and go from there. Seal up the airbox and replace carb boots as necessary. Rebuild the brakes. These are just a few examples, there's a whole lot of maintenance to do catch up on and the whole shebang can be found in the Mega Welcome that you received from BassCliff in your other thread.

Welcome!

41,000? Might be 141,000. Doesn't really matter if the rest of the bike is good.

If it's running ok- don't bother it.

Valve adjustment is critical. I'd also torque the cylinder head. If it hasn't been torqued in some time the nuts will likely be stuck. Hit them with PB Blaster or similar and let them soak for a while. You need to back the nuts off about 1/8th of a turn before making them up to the specified torque (check your service manual).

My 79 GS1000 just rolled 41,xxxx and I have been wondering the same thing. The bike runs great. It looks like it's leaking a little oil around the head gasket. I am hoping I can get away with a new gasket and valve adjustment. It does seem to make alittle mechanical noise. But all the other GS's I have heard don't sound any different. I wear ear plugs 99% of the time so when i don't i swear i hear things

I am hoping to do a few track days at Mid Ohio next year. IF I can get the suspension swap done this winter.
