Final note on my end. Basically this got a complete rebuild. New crank, bore and pistons (left cyl was to rusted for just a hone ) All new seals.
He brought over some parts to install, chain and sprockets, pro-flo filter/adapter, case saver. Worked out well as the bottom end was together waiting on cylinders. Only road block was the water pump. Manual recommends replacing bearing when replacing seal. Bearing felt "notchy" when inspecting it, and took a couple extra days to get one.
I regret not having been able to do anything more with it. My back blew out Fri morning after I did second heat cycle and was waiting for it to cool to retorque the head. You know, final test and tune. Hell, wasn't even 100% on clutch adjustment, only took it once down the driveway. IMO thought it had a bog down low, but he also geared up because he was changing tires. Glad the default settings for the carb work !!
So basically any break in procedure is all on him.
Another shout out to Lakes Motorsports in Waterford, 4 days after dropping cylinders off and picking up crank, gaskets, and a few other things, the cylinders were here via Brown !!
