Probably not a bad idea to drain the oil tank and refill but there's no oil "pooled in the lowest point in each part of the bike". This is dry sump engine, i.e. all the oil is in the oil tank when the engine isn't running. If the check valve in the oil pump has failed and allowed oil to run from the tank down into the case, you'll find this out the first time you kick it through when oil comes out the breather. actually, after 15 years if the pump's check valve has leaked, the oil may have already flowed out the breather.

Personally, I'd buy it, part it out, double or triple my money, and then buy a nice low mile EVO....There are tons of them to be had for cheap. I have a buddy that just picked up a 2000 883 with 8k miles on it for 2800 bucks.

Pardon me, but Pyro knows what he is talking about and what he is talking about is the check valve has certainly leaked and filled the crankcase with oil. If you fire up the bike, some of this oil will be expelled thru the breather but most will end up going through the bearings of the engine.
So like he says, better to tear it down and check the condition of the engine. The alternative is to try to start it and that will do it no good at all.
So, if it starts, so what? You gonna ride around on a rusty piece of crap? Not me.
I say do the engine check out first, then if no big problems are found start with the massive clean up on the frame and other stuff......pg

I beg your pardon, but I know what I'm talking about too. When my '59 sat for 2 years in my dad's garage, the oil leaked past the check valve and out onto my dad's garage floor through the breather. Another time after it had sat over a winter's storage, some oil had leaked past the check valve and into the case but not enough to flow out the breather. When I kicked it in the spring, it blew some oil out the breather. At that point I removed and cleaned up the oil pump check valve. If he wants to be sure, he can remove the drain plug from the case and drain whatever is in there. He's talking about buying a bike for $650 that has been sitting for 15 years and according to his post he's not looking to build a show bike like yours but something to ride around on locally. If he can get it to run, then he can do that and if it smokes, rattles, etc then he can tear the motor down. These ironhead motors can take quite bit of junk internally and still run. I rode mine a thousand miles or so with a broken off chunk of lifter guide as big as a finger nail rattling around in the gear case. I rode it 10 miles to the nearest town once with all the needle bearings gone from one tappet. Outside of eating up the surface on that cam, it did no other damage to the motor and still had compression and ran 60mph though with a helluva clanking! After I put in a new tappet wheel and a new (used) cam, I rode it a few more years. I'm not disagreeing that a "proper" rebuild would start with a motor overhaul, I'm just saying there are faster and cheaper ways to get back on the road and probably not causing any more damage than is already there.

Is that why I had to clean up oil off the floor when I removed the cam cover to replace some tappet guides and shim the cams? Or perhaps that's why I have to wipe up oil off the case when I take the rocker boxes off?

The point is that once the engine was shut off for the last time, the oil pump also stopped pumping. The oil that was currently being circulated in the engine doesn't just magically return to the tank. It pools to where ever gravity will take it. You may not have a problem just adding oil to a bike that's been sitting for two years, but I have a big problem with taking a risk that feed and return lines in a 15 year neglected motor will get blocked and cause a situation where the pistons are running dry. Show bike, daily driver, whatever, a siezed engine is a bit more of an issue. One that can be avoided.

I hope you're not talking about the plug that has caused so many headachs and inspired countless threads and posts of warning, because it's not really a drain plug.

It sounds like a great project, and that's the right price. Pull the top end off, check out the motor, and if the bottom end is shot, hawk the parts on ebay and you'll come out quite a bit ahead. If the motor looks good, put it back together and get it on the road. I've seen a lot of guys on these forums asking if they should pay twice that much or more for a non-runner.

Worst case scenario, you tie up your dough for the winter, learn a bunch about Ironheads, and have to part it out.

Best case, you get on the road on a bike you resuscitated yourself for under two grand (maybe less).

Yes, the "drain plug" that is not a drain plug.
Don't make that mistake of even trying to loosen it. Leave it alone!
That plug is anything but a drain. It was put in there to plug a hole required for machining the engine. It should have had the hole welded up, but HD decided to install a one time use plug instead.........pg

All I know is it's a hole that goes into the crank case and if you remove the plug any oil in the case will drain out. I've removed it and no oil came out, i.e. the sump was dry.
