lol

Yea I instant cringed on that one when I saw it.  But yep good opportunity to drop a big bore kit and performance cam in there.

[gnarlycharlie4u]

got the cases split just now and this song came on:
Skatalites - Split Personality

I'll get pics up tomorrow.
The gear faces look immaculate. Good news except that I just bought a backup transmission for $10 just in case.
I'm still debating on polishing them as per Hondaman's writeup.

One primary chain looks a little more stretched than the other so those are gonna get replaced.the primary tensioner looks like it's in good shape but I might as well replace that while I'm in there... or at least the roller.

Speaking of which... where the heck do I get a set of primary chains and a tensioner?

Also... I know it's a way off but would anyone recommend using gasket sealer when putting the cases back together?

[gnarlycharlie4u]

whoops I almost forgot about pics.

Pistons off


Cases split



Clink... plunk "wtf where did this fall from?


oh!


Also while I'm in there I think I'll polish the gear faces.


I ordered all but one case bearing from Manassas Honda (thanks again Drew).
The one they couldn't source I got from Motion Industries which is just down the street from where I work.
I managed to get a blind hole bearing puller on loan from Autozone instead of spending $170 on a new one.

Just thought I'd take a moment to update you guys.

Being broke and having way too many projects is killing me at the moment. I planned on getting this motor back together early last month but one thing after another has prevented me so far.

I got the primary chains, rollers, etc... all done (a WHILE ago.)





I'm now planning on painting the cases black and using stainless hardware to put it all back together. I'll be taking all of the lower end back out once the 76 GL1000 gets back up and running. Then it's time for paint!

Next on the list is of course all new gaskets, piston rings, and cam chain.
I don't suppose anyone has a hook up on a good set of +1mm over pistons? I'm not looking to go big bore on this motor, but a little extra oomph would be nice.

build is looking good!  how are you planning on polishing the gear faces?  i've considered doing Hondaman's method in his book as it's apparently quite worth it, but it's quite a bit of work!

I've considered it, but I'm still on the face about it. It's going to happen to the 72 but I'm going to test it on a spare 77 tranny gears I have first and see how it comes out.
My main concern is having them polish unevenly and thereby causing more problems than they'd fix.

[wannabridin]

so what method are you going to use?

[gnarlycharlie4u]

so what method are you going to use?

lapping compound + rotation.
I want to do it in the case but I have to be careful to not get the compound in any of the bearings or on any roller surfaces while I do it.

Also I need to figure out something that will turn the gears for me since I don't really want to sit there for hours turning them by hand.

[wannabridin]

ya, i was considering doing it this way too, but i have all new bearings, so i figured that would work out a little better with unfinished cases, ie still need a good going through!  let us know how it turns out on your spare trans!  i'd like to see someone do it first, haha!

[gnarlycharlie4u]

^^ #1 reason why I have yet to do it.

looks like I'll be the guinea pig. I mean I don't have all THAT much to lose since I have a spare trans and a couple extra motors.

This looks like its going to be amazing! Get yourself a slow speed drill and make some sort of linkage. Also, I love the black case stainless hardware look. Get it powder-coated... you may as well! I have a guy over here in NJ that has about 15 different blacks from mirror gloss to flattest flat, and then another 10 black textured finishes. He did all the wrinkle black on my Buell. He also does gun coating and piston / anti-friction coating. He used the flat black gun coating on my yz250f fork tubes because its thin and stong so you can clamp them. I abuse the piss out of my yz and thats held up really well too. I could give you the website if you want to check it out.

Very nice looking project and great pictures too!

please do share.

I just bought some paint for the motor and some other stuff for Joe's K3 (20'sNaRanger) He really needs to stop being so effing lazy and start a build thread.

Here's my reciept:


Cast Iron for the motor
Olds Gold for the jugs or head... or both and I think I'm going to sand them down so they're bare metal at the tips of the fins.

I really wanted bronze but I couldn't find a good metallic engine enamel ANYWHERE!

I've never painted anything before so things should get pretty interesting, o.0

and while i'm at it... here's a couple more pics of my workshop.

OH MAN, it USED to be soooooo clean and empty. You guys should see a recent picture...man o man.....

dude... you should have seen it when I only had 1 bike.

actually it was a #$%*hole then too.
after I got my 2nd bike I commandeered the whole garage, cleaned out the piles of #$%*, built the shelves you see there, bought that massive workbench by the door ($20), hauled those white cabinets home from the dump, moved EVERY shelf and cabinet in the garage at least twice trying to get it set up, piled all the tools in the middle of the garage and sorted them,  and started stockpiling parts. LOTS AND LOTS OF PARTS.

I went from one bike to 7 in about 9-10 months. In the last 4 months I've started 4 other project bikes for other people and rebuilt about a dozen sets of carbs when I was too tired to do any REAL work 

[gnarlycharlie4u]

Hey sorry for the lack of updates i've had a few other bikes distracting me:
3 gl1000's
my buddy's K3 build; http://forums.sohc4.net/index.php?topic=92891.0
and a cb400

Incidentally I'm looking into mounting dual discs on the front of the 400 and trying to figure out how to lace a rear F1 hub to a 19" or  18" front rim.
