1974 Honda CB550. Monoshock. Engine Build. "BLAC"

[japstar]

just found a big box of seals at my doorstep!

There goes the money
It always hurts me when you have to pay a lot of money for seals. But hey, at least you are sure your bike won't be dripping for the coming years.

 

[BLAC]

That was only some of the money

more old OEM:

What's the best way of getting OEM oil seals? I notice the kits on eBay but prefer the security of OEM.

Do you just order the individual part numbers or can you get an official engine kit?

 

[BLAC]

I could not find a kit of OEM seals, so I ordered them all individually though Partzilla.

Not too spendy... here is the list I put together for my 550k0

If I want some OEM parts, I order from www.cmsnl.com. Although it is a site from the netherlands, they ship to the USA too I think. (I am located in Belgium)
They have the parts lists shown for every bike, en you can just order by following the references on the parts list.

 

[coyote13]

If you have a local Honda powersports dealer you can order most OEM seals and parts through their website and have the parts shipped to the dealer free of charge!

 

[BLAC]

Yes, but Partzilla had free shipping on my order and their prices are very reasonable. I live in LA so I get in the car and drive as little as I can

 

[BLAC]

Progress! (kinda)

I got my crank back from APE! I didn't have it fully lightened, but I did have it 'race balanced'. I also for some other bits and pieces to help me get this thing put back together!

Now I just need my rods, cylinder, pistons, and head then I will be rollin!

pretty

 

[BLAC]

Got some pretty parts in the mail.. ;D

Monoshock came in from Racetech. I couldnt be happier with it! I havent ridden on it obviously but it sure does look the part until then..

They weren't sure if they could put ride height adjustability on it because of how short it is, but they made it work and it looks great!

Of course I had to bolt it up.. ;D

 

[BLAC]

More goods! It's go time!

Stage 3+ JMR Head w/oversized valves

Intake Port

Exhaust port:

Vapor blasted, decked and bored cylinder:

Polished, peen'd and balanced rods (with late model 750 hardware). I had a gram scale out and each one is 301 on the dot! (not to second guess JMR's work, more to appreciate it ;D)

Wiseco forged aluminum pistons:

Now it is time to start the assembly! (don't worry, y'all wont miss out on the build... I will have tons of questions as I second guess myself throughout the entire process) ;D

 

[BLAC]

About that engine...

Cleaned and lubed:

Sealed up and shifter bits installed:

Pistons joining the party:

What a stud(s):

Anyway, that's where she sits!

That mystery plastic piece looks like the tip of a caulking gun...

Looks awesome. How much did it cost? Maybe I missed it, but where did you send it?

Bryan, you made me snarf my coffee! The bike is looking incredible.

redwillissuperman, ping me anytime, happy to give you a quote on a project and by the way, return shipping is free. I'm also happy to send you inbound labels that cut that cost about in half.

Thank you guys for the good words, that is greatly appreciated!
