Oil Light
I took off the oil tank and cleaned it in kerosene. I also connected a new line for the drive chain luber. In the process, I disconnected at the pump, the tank drain line and the return line from the cooler. Now, the oil light is on. I drained out a little oil and it went off. Now it's back on. Any suggestions or ideas?

Do you have an oil pressure guage? It may be dirt in it, or it may be due to low oil psi, for some reason or another.....
Are you sure the lines are back on correctly?

I just printed your picture and will double check my setup. I'm pretty sure it's correct. Thanks Dave.

Hoses are correct. There's also a small puddle of oil coming out of the crankcase vent hose too. I'm suspecting the oil tank drain to the pump feed hose. When I disconnected it and pour a little oil into the tank, it drains very slowly. Is that normal? I'm beginning to not like this.

In that picture, there's a brown circle around a large headed screw. You don't want that one, rather the smaller lower one to the left if it. Take it out and remove the spring and a check ball. Clean the opening out and make sure the check ball doesn't have any dibris stuck to it. If there is, it'll cause oil puking out the vent....

Well I took the tank back off and checked the drain to hose and it was clear. I don't understand what I could have done to cause this. Yesterday the light was on and I took some oil out of the tank so it could breathe and the light went off. I went for a ride and 20 minutes later, the light came back on.
I can't see any connection, but I also replaced the drive chain oiler hose, which had a leak and sealed up the primary case again. Someone closed it off so it is self-contained. I put on a new gasket, tightened up the primary chain, and poured in a half qt. of oil.
Any other ideas on this? Is there some way you're supposed to prime the pump?

You could simply have a sending unit that went south, Chris.... a pressure test would onfirm this. If the sending unit wire is grounding anywhere (rubbed through) it will also make the light come on.

Well, once again you have fixed my problem. I'm sure glad you're here.  The oil lines on the bike are all braided. The former owner had zip tied a piece of plastic wire loom one hose so it wouldn't touch the pressure sending unit. The piece of plastic slipped down and I didn't notice it. Problem solved, thanks to you.
But don't I feel foolish. I spent the better part of 4 hours trying to figure this out. Me, my tools and my garage floor are covered with oil. But hey, the bike is back on the road.
Thanks Dave.
