    GS1000G locked up engine

    My current build is a 1980 1000G shafty, The engine was locked up sometime between the beginning of the build where it spun freely to the now, so I squirted PB blaster in cylinder and let it set eventually breaking it free. Now I am worried that the engine may need new rings due to a low compression. That being said I have not done an official compression test because the battery in the bike died. I can however push the bike down the driveway while in gear. The bike will pull itself under its own power but wasn't able to check the real acceleration due to no brakes installed yet


    so my questions are as follows

    1. Will the rings re-seat after a little running?

    2. Is there something I can do to help the process?

    3. How long does this take to re seat if it does free the rings up?.

    4. The engine starts and runs, idles well but I didn't let it run too long because the oil leak where I had the engine welded, but did check and it pulls itself under its own power.

    just looking for guidance on what to do.

    I'd focus on getting the bike running first. Be sure to adjust the valves and properly rebuild the carbs. Then go put some miles on the bike and see how it runs. After a couple hundred miles then perform a compression check if you want to know how well the engine is sealing.

    To measure is to know.

      Thanks Ed, the carbs have been completely rebuilt and bench synced new o-rings plus sealed the intake, replaced the boots O rings. the Bike overall seems to run pretty smooth and revs just fine, will sit there and idle just fine. I just wondered what the possibility of the rings sealing back up were.
      Also on a different note I didn't find that carb choke bracket you messaged me about for the bs34 carbs

      here is a video of the first start up



      ps i know its smoking there was oil that was soaked up by the header wrap, which will be coming off shortly
