It has been some time since Randy's GTG, and I hope some of you have had the opportunity to put some time on your Asian 660s. So, how are they holding up??? My Flying Tiger needed a piston pin bearing after about 10 tanks, so it got the Big Bore treatment from Dr Al, but the bottom end (main bearings, crank, seals, etc) all still seem fine. I'm in the process of building 2 more. Actually, both are running, but one needs work on the chain adjuster and the other is not oiling, so I ordered a new oiler. Merry Christmas to all, and tell us how your 660s are doing.
