I've completely torn down my motor in the process of converting the tranny. I'm concerned that the oil pump will be empty and will not pump anything due to lack of "prime".....It's gonna have to suck oil out of the resivor before it gets to any moving parts. How long is that gonna take ??

Is there a procedure to put oil in the case prior to start-up ?? I'm concerned it might take a while- even though I've used assembly lube, etc...

What did you other guys do ?

Thanks, Eric

 

take out the spark plug and crank it over until oil comes out the gallery by the cam.

 

CTRaptor,
Will I be able to get enough speed up to actually get the pump working? I'm not second-guessing you, but have ya had sucess doing it this way? If so - sounds like an easy solution !

Thanks, Eric

 

Before you put the head on, pour maybe a half quart in the bottom end.

 

After my rebuild my bike took almost two minutes of cranking before it got oil presure all through the system. I disabled the coil(tether switch) and left the valve adjusting cap off nearest to the oil line feeding the head and waited for it to begin pumping before I let it have juice. I used plenty of assy lube so I wasn't worried about it spinning at the low speeds however if the bike had fired it would have spun much faster(maybe engine damage, maybe oil pressure sooner). I also had to "blow" the oil down into the motor with a SMALL amount of compressed air. Another trick would be to let your oil set in the sun to make it flow easier.

 

I'm all finished with the motor and fired it up - here's what I found:

I attempted to hand-crank it around to see if any oil would come out of the head galley - nuthin, cranked it quite a bit and as fast as I could. The level in the tank didnt drop either.

I already buttoned up the motor so adding oil the the crankcase was not an attractive option.

Loosened the galley nut and fired it up - seemed to run about 30 seconds before oil came out. Seemed just fine, but good thing I used assy lube !!

Seems like adding oil to the crankcase prior to final assembly would be the best way to go to minimize the run time without oil.
