Normally I finish the engine last put it in the motorcycle and go through the run-in stages. Between the time I finish the engine and get it running is usually less than a month. This time I got the engine done about 10 months ago and it probably won't see action until sometime this Summer. It's critical mating parts are coated with assembly lube. I set the left cylinder at TDC and rotate it about every 6 to 8 weeks 360 degrees. My thinking is that the valves in the cylinder at TDC are closed and, other than pre-load, the valve springs aren't bearing additional loads. The right cylinder is also at TDC having, technically, just finished, an exhaust stroke, so the exhaust should be closed while the intake has started to open. The engine has new springs, cam and new flat faces on the tappets. My concern is not so much about the valve springs as it is with wiping off the assembly lube on the cam. 'am I being overly concerned? is there a better crankshaft position to park the engine in? Your thoughts are encouraged and welcome.
