i had my motor done about 2 months ago. the works.its an 88 twin cam in an 03 electra glide. turned it into a q106. did everything except lifters. even did a s/e oil pump. my problem is im getting to much pressure in the oil system and my dip stick keeps getting ejected from the bike. ive gone thru four of em now. i talked to godspeed ( who built the motor ) and he sais this has never happened to a 106 he has built. he thinks it might be the crank case breather or something to do with rsd air cleaner i have on the bike. every time i jump on it i lose the dip stick. please help!!!!!!!!!!!!!!!!!!!
Have you checked CCP, is it what it should be for the build? How 'bout a a leakdown test?

The reason I ask those questions is that if you do not have properly seated rings and/or a good piston/cylinder fit, then you can have excessive blow-by which creates very high crankcase pressure and that can cause the problem you are having.

Are you getting much oil blowing out the crank breathers (on the heads)?
Fully agree that \\;it is excessive crankcase pressure. \\; It it is either the inability for it to exhale or you have an abundance of blow by.

Something is wrong.
Either there is huge blow by pressurizing the crankcase, or the breather is plugged.
checking the breather is the easiest thing to do so start there.
If that looks OK then I'd go for a leak down test of the cylinders and see if there was something amiss in the rings or machining of the jugs,
