Hi Guys,

so i've done a total strip down and rebuild of my K100 LT engine. As i went along i lubed up various bits and pieces with engine oil, however, i'm concerned i haven't saturated it enough with oil. I'm close to the point of first fire up now and i'm just wondering what to do to best protect the engine and ease it into the running? 

Once i've filled it with oil, should i let it stand for a few days to let the oil work its way in? or should i put it in a high gear and try pushing it should so the oil pump moves the stuff around the innards? or do i just hit the starter and let it idle for a while?

Also, once it is fired up, what is the running in times/ distances for the engine?

cheers muchly

Should be all you need to know for that little confidence boost.

Well done on getting to the starting phase.

Letting it sit won't do a thing as the oil is below almost anything that is lubed by the pump.  I usually use engine assembly paste on the cam shaft and followers and start it and let it idle till oil pressure comes up which should only be about as long as when you do an oil change maybe a few seconds longer.
As for running it in just take it easy don't rev the shit out of it and vary the revs and load while running.

JMHO as a shade-tree mechanic, but it wouldn't hurt to pull the plugs and spray in some fogging oil.  Of course fogging oil is designed for a different purpose (off-season storage) but is convenient for for pre-lubing cylinders as it comes in an aerosol can.  Can't hurt, eh?

Edit: I've also read in numerous places that it's also a good idea with older engines (like K bikes) to run them on dino oil for the first 20k miles to let the rings seat properly as supposedly synth oil is too "good" to allow that to occur.

I always spin a newly built engine up on the starter with the spark plugs removed to get the oil around it. Keep an eye on the oil pressure light to make sure it goes out, and crank it for a minute or two after this.  On a K bike I would disconnect power from the fuel pump to prevent flooding.
