Good work Jason! Last spring I was putting my Goldwing back together to take a spin on it from the winter maintenance I had done. And the last seat bolt I sheared it off putting it in. The bolts for the seats on the Wing are about 5 inches long and quite frankly a #$%* to get started correctly. So I take the seat off and basically do the same thing you just did but the bolt wouldn't come out! So I gradually increase the drill bit size to the point the bolt was just shavings. Tapped it out with the original size tap and installed hardened seat bolt's with quite a bit of anti-seize on the threads. Glad yours came out easily for you. I've yet to drop my oil pan on my K3 but am thinking this year might be the year.  ;)

Thanks Brian!

I guess I am going to order this petcock unless there are any objections?

Seems like he has sold a bunch.  Mine is totally shot.

I am waiting for a day where I know I will have the time and some warmer weather to tackle sealing the tank.  Thinking about using prep and etch from HD before doing the formal sealing process.  Just want to get as much rust out as I can before beginning the sealing process.

In the mean time, I am going to do some soda blastig on the motor to clean some stuff up.  It really needs to be pulled and put on a stand to be cleaned properly, but I will wait to do that until after we hear it run ;)

Alright guys, a little update.

I got the POR-15 kit in and went through the whole process yesterday afternoon.  As far as I can tell, it all went pretty smooth.

I do have one question though.  Even after having the radiator shop braze the pin holes shut, after using the metal etch to remove the rust, a couple more opened up.  I know POR-15 is know to be able to seal those pin holes and I taped them up during the sealer process, but I wondering if I can put in a second coat of POR-15 tank sealer?

Another can is $20 shipped and I would wait at least 5 days before going in with it.  I am confident the whole tank is coated, but it just looks kind of thin and I am just wanting some extra peace of mind before putting in all the labor of painting just to have it ruined by leaky pin holes.

Can POR-15 take a second coat over the first?

Thanks!

So just an update.

I called POR-15 and they said not to attempt a 2nd coating because it will not bond to itself well at all. 

He said if I was worried about the pinholes, I could reenforce them by painting a little POR-15 on the outside of the tank over the pinholes.  (Remember my tank is stripped of paint.)

The problem is, I don't have any left over and I really don't want to spend another $20 for more POR-15 just to use a tiny bit on the outside of the tank. 

If the tank is now water tight due to the first coat of POR-15, which it should be but I'll test it, could I just skim some JB weld over those areas to reenforce them before starting the bondo/filler work?

Thanks!
Jason

Spend the $20 to protect your paint. You need to double check that JB Weld is fuel tolerant. Painting holes with it may not last as gas eats thru then spoils your paint.

1 oz. of prevention...

True. The more I think about it though, the more I just want to test it with gas, and if good, just trust the liner and go strait to body filler.

Maybe still JB weld but only to reenforce the metal. Not to act as a sealer.

I'll see how it does with a gas test then decide.

Use water, not gas. If it does leak, then cleaning the gas from your tank is yet another step! Liquid is liquid. Save the $ and use tap water. Then pour into the drain or garden  :)

So I'm working through the 3K tune up and so far everything is checking out. 

1. I gaped and installed new plugs.
2. Checked the points gap - they checked out and looked good and clean.
3. Checked the cam chain tension - the screw didn't move. Safe to assume it was fine and didn't need to move?
4. Started on checking valve clearances and cylinder 1 seemed fine with the feeler gauges. Will check the rest tonight.

This thing ran 3 years ago so I guess its possible that a lot of things are setup properly already? I'm just not finding things I need to adjust. At least not yet ;)

Still need to check the timing (which I'm not sure how to do, or if I really need to since it WAS running), check/adjust the clutch, mount the carbs, cable up the new throttle and clutch cables, wire for spark, fill with oil and gas and give her a shot!

Getting excited to try to start it up!

Re: Working Toward First Start 78 CB550 Update: She's alive!

Well... SHE'S ALIVE!!!

I adjusted the built out a new set of bars (new throttle, and clutch lever, as well as new cables), mounted the carbs, wired up the ignition and starter, filled with oil and gas.

Looks like at least the lower portion of the tank is sealed! No leaks so far but I only put about a 1/4 tank worth of gas in.

Turned the petcock on to my newly rebuilt carbs for the first time, the bowls filled up, AND crap! There comes gas out the #3 overflow tube. A couple taps on the bowl with a screwdriver handle... All is good.  No leaks since.

Took the tappet covers off #1 and #4 and ran the starter with no spark to make sure oil was getting to the head. Everything was wet with oil. All looked good. OK, ignition on. Hit the starter for a few seconds, nothing. Hit it again - heard it sputter. OK, thats promising. Repeat this a few times with a buddy giving a little throttle and holding the choke closed (choke able rusted and won't pull) and finally it started up!!!

Let it run a bit, and dialed up the idle screw so we could let go of the throttle. And there it was, purring away. 

Killed it and started it a few more times and after the first start it fires off FAST with no issue.  Also kicked it with ease.

So two initial questions.

1. The kick start would not catch with the clutch pulled in.  Only with the lever out. Thoughts on this? Is that normal? Doesn't seem super safe to me.

2. This is less comforting.  As we back down the idle screw to see if if would hold a nice 1200 RPM idle (which it did very well), it got quite enough for us to hear a rattle coming from the transmission area inside the crank case.  I need to do some more trouble shooting but any thoughts on this? What to check and in what order?

I will try to get the noise on video and post it.


Overall I am thrilled! First bike first project and its running!!  Can't thank everyone enough for all the help and support!

Jason

Here are a couple videos.

This one is starting it once it was warmed up.

This one is just it running. Not sure if you can pick out the rattle noise or not. I will try to do another video focusing on that sound.
