It is usually the check ball. Maybe dirt, maybe ring groove on ball or valve-replace or reface radius on valve, or maybe needs lapped. I use the method described in, I think, the original Easyriders tech tips where you arch weld a rod to a 3/8 ball and use this to relap the ball seat. I just drain the oil out of the cavity enough to get to the seat and use a small amount of fine compound and lap, clean, and lap several times. Clean cavity well with Q-tips. I'm sure some will disagree but I feel that if a small amount of lapping compound does go in the oil it is no big deal, to me a comparasion is a oil tanker spilling in the ocean, spill vrs volume. Anyhow, good luck.

Sorry to get into this so late Folks,

But let us consider a few things about our H-D ball checks.
First, those of us who cut motorvalve seats know that a thinner seat seals better than a wide one;
Lapping and cutters widen the seat, and leave a finish that is either the grit of the compound, or toolmarked with 'chatter'.

An effective seal against oil must have a finish of mating parts that is smaller than oil molecules.

Burnishing is a technique where a hardened polished surface is pressed upon the seat to smooth it, without removing metal. Thus no abrasives are needed, and no chips from a cutter are produced.
It can even be performed with the OHV pump installed, and full of oil.

But the tool is not cheap, and demand has me in the middle of producing yet another small batch.
Interested folks should email me direct at liberty@npoint.net.

Thanks,

My suggestion has always worked for me, but this sounds like a preferred method. I'll be contacting Cotten. Thanks.
