    Piston rings?

    I am in the process of redoing the motor on my 1978 Gs750 and want hone the cylinders and install new rings while in the process, are there brands that are better or one to stay away from. Any info would be great. Also does anyone know what size tap I would need to get to chase the threads in one of the sparkplug holes? Thanks in advance!

    OEM rings are tried and true. There is some guy selling aftermarket rings on ebay, but in all my years here they is the only aftermarket rings I've ever seen for GS's.

        Thanks, I will go with oem, wasn't sure about after market, had no issues with the rings or cylinders just thought since it has 56000 on it and I was doing some work it would be the right thing to do. Hopefully with a light hone and new rings it will be good for another 56k. Thanks for all the info

          Probably be good for 56,000 more with the rings that are in it. How is the compression and does it smoke?

            Not sure on the compression but was running when I tore it apart and no it wasn't smoking. I want to freshen up the motor while I have everything apart. Plans are to wrinkl black the motor and chrome all the side covers before the motor goes back in. Valve seals and lapping are on the agenda as well.
