Working on getting a 350f on the road. Top end is done, honed, new rings, valves lapped, no problems with spinning it over. I used pre-assembly grease on all moving surfaces I could access journals, lobes, tappets etc. Have not put oil in yet, nor connected a battery, just hand cranking it.
I have started adjusting the valves, and it seems like once some of the pistons are set at TDC and stopped, the motor becomes hard to turn with the kick start, almost as if it's locked up.
Put it in [5th] gear, roll it backwards, roll it fowards, seems fine.
The bike sat for an unknown time period before I worked on it, appears to have been inside storage.
Is there a situation where the kickstart locks up/ or maybe the cam lobes and springs create a TDC 'notch' that it likes to settle in where it is hard to spin out of? Like if there is enough inertia it just rolls over and if it settles between valve compressions it becomes harder to roll over?
Someone said pull it back apart- perhaps, but no thanks?
Also- what type of feeler guage do people use to snake down into the tappets??
Is it an obvious thing that the exhaust tappets further down in the hole and are less accessible than intake on this motor?
