You can also tap in swingarm spools (see them on several bikes like riverfever's) so you can use a paddock stand.

thats the idea! im looking at some pitbulls on craigslist

I run a pitbull with my cb's.  You can just use the flat arms on the stands to go under the swingarm too.  It's pretty sturdy.

I've done that on a few projects and it works rather well.

I like the swingarm spools on Godffery and riverfever's bikes.  I think having a more positive hook-up on a spool is safer than just using the flat portion of the swingarm resting against the stand.  I'm sure it works, but in California we have earthquakes.

I am also installing spools on my 550... and hopefully tonight.

The left side flat arm on my paddock stand is starting to bend downwards because of the added pressure on that side whilst standing the bike up. Will feel much more comfortable with spools installed.

I really like that new stand I picked up from Cycle Gear but supporting it from underneath the swingarm just isn't ideal (it's got both a swingarm mount and a spool mount). The spools end up in the perfect spot and it's so much more stable. I stole the idea from Dave Barbier but I did go with Woodcraft spools instead of less expensive eBay ones because they use an 8mm bolt but the spool is still the same diameter regardless if you get the 8mm or 6mm bolt. .

[BLAC]

Great info! I have my shopping list put together.  I'll check out you thread (or look up the person you got the idea from) to get pics of where you mounted the spools 

In other news I made a lot of progress on the motor last night.  Pics to come in the AM

[riverfever]

I should also add that the Woodcraft spools (in either 6 or 8mm) use the exact same spool itself which is very nice on our bikes because the spool diameter is the same and space is at a premium down there between the welds. If you would like any measurements let me know.

About that engine...

Cleaned and lubed:



Sealed up and shifter bits installed:


Pistons joining the party:


What a stud(s):


This is where things took a turn (briefly).... I was down to installing THE LAST case bolt.. the long one at the back left corner, but for some reason it wouldn't go all the way in and it wouldn't catch any threads.  It felt like the bottom half of the hole was filled with Hondabond.. i shined a light down into it, but it just looked like the whole ended before the threads started, but again, the bolt was hitting a rubbery surface, it wasn't hitting metal. 

Now I'm sure that I accidentally dropped a dowel, gasket of SOMETHING in there and I'm going  to have to pull the cases back apart to see what is going on. Before doing that and after scratching my head for an hour, I finally tracked down a long skinny screw.  Being low on patience and other options, I drove the screw into this mystery and once anchored, I used a claw hammer to pull it to the surface..

I'm just as confused as ever.. I have never seen this little bastard before in my life. I hope it wasn't supposed to be in there, because i destroyed it while removing it...




Anyway, that's where she sits!

[koendd]

funny #$%*!

looks like the cap of a hondabond/sealer tube

[BLAC]

That's what I thought when I pulled it out too, I pulled it out and immediately looked for my HondaBond to make sure I didn't do something stupid and put the cap in there haha.. but it is really rubbery and semi translucent..

[BLAC]

Dude! Now you're screwed... that cap is supposed to be in there  Stinking amateur wannabe motor builders! You could screw up a 2-car funeral or tear up an anvil with a rubber mallet. Start over please and put that back where it belongs, cemented in place with Permatex.

Geez my patience is wearing thin- 

  I do what I can! 

but... that isnt supposed to be in the motor at all.. is it? I have looked at 3.2 million engine schematics and forum threads and can not find a mention of this thing.

The only thing I can think of is maybe it is a cap used to protect threads when vapor blasting?

[BLAC]

It's from the uber-rare Sandcast 550 cases, made only 1 day in the month of April, and only 19 documented cases had it. You've just devalued that bike immensely. Please erase that post, put it back, and Trey pretend like it never came out. We won't tell when you go to sell it 


No, doesn't belong, and no, it's not from Vapor Blasting either.

 

[BLAC]

Mystery solved, it was a thread/hole protector from the vapor blasting process.

I might have blown it in farther down into the hole with my air compressor, but either way I should have chased the threads and found it earlier.

All good, mystery solved

Such a nice guy, right?!

Cylinder is on and pistons are sittin pretty!

Man, that engine looks good!  Great job on this bike, Bryan!

Thanks Ron!  I am about to put your valve cover to work once I need to degree the cam.  I will engrave "Restoration Ron's Good Karma Cam Cover" on it and over it up to other 550 owners once it is milled out =)

thanks again!

So you got yourself a Mega 126-00 cam?

[BLAC]

I think I'm going with the 126-20 

[Stev-o]

Nice job...no matter what Cal says!

[Camrector]

I'm pretty sure I've mentioned it before, just make sure those valve reliefs are big enough for the 126-20. They don't appear to be now.
