So I need pull the pump off and work over the check ball seat. This didn't go very smoothly, but I have to post it so someone else can learn.
Rear pipe has to come off.
Pinch off the gravity feed line.
Unpinch and dump the oil, because it needed to be changed.
Two hex bolts hold the inner housing and four socket heads hold the outer and inner housing to the crankcase.
Some bolts are in tight quarters.

This tiny circlip holds the drive gear to the shaft. It's tough to get off, and will give me more problems later on.
Clip's off and the housing will slide off now. There's a woodruff key with gear so don't loose it.
With a little a tap housing comes off.

Another drive gear and another woodruff key.
I pulled the cap, spring, and ball. Here's the seat and I don't really see any problems.
I should have gotten more pictures of all the red silicon in the oil passages. Don't use silicon in a motor. This might be what was hanging open the valve.
I had Rusty at Okie City Customs work over my valve seat. He had a special tool for cutting and I believe he lapped with a Evo pushrod, too.
You can't really screw up putting in the gears. The the wide ones go the crankcase side and the drive gears have the slot for the woodruff key.
Key goes on the shaft.
Gear on the shaft and key. It's a bit tricky to get the gear on there and not knock the key out of place.
Ooops! Put the gasket on first. The bolts are just holding the gasket while I put the key and gear back on the shaft.
Inner housing with idler gear goes into place.
Bottom bolts put in temporary to align everything for the outer gears to go on.
Key and gear go on and it's tighter and tricker than the last one.
