Hello,
I just finished installing new cams and lifter's in my 2010 Twin Cam. Is there a way to prime the oil system prior to the first start up?

 

I use lots of oil on the gyrotors on install and call that good. Let it sit overnight with the feed line hooked up or pressurize the oil tank slightly and turn the engine over untill you have pressure.

 

If you lubed the crap out of the oil pump, you can turn the rear wheel in 5th/6th with plugs removed. I did that to verify pump was working after installing cams and prior to putting push rods back in, then rocker covers back on. Anyway, could see oil going where it should

Another thing - you probably changed oil and filter, it helps to poor oil directly into the oil filter saturating the filter pleats prior to installing it. Oil pressure will build up quicker this way...

 

also,make sure you put about 1/4 quart of oil down one lifter block hole after youve got the cam cover back on
