WeberKid's Build. CB450 project.

that appears to be a honda cb360

If you're building from the ground up, ditch the OEM frame. It's decent but a bit flexy for really bashing a canyon. If you do ANYTHING to that central upright your frame will go from flexible to wet noodle. A Seeley Mk.IV style frame with the engine slung under it would be seriously hot!

good luck getting it titled

my vote is to get a 450 frame and cut modify then reinforce and gusset the entire thing.....you shouldnt have any problems doing it that way.

I could easily do this. in fact, it was silly for me not to think of it from the get go anyway as the improved rigidity seems like a good idea. I'll be sure to add it to my list of things to do. Thanks a bunch!

Ok, here's a Seeley Mk2 chassis:

But the one I'm thinking of is the Mk3, like his Condor bikes had:

Notice no bottom cradle....engine is stressed member

Here's a Seeley Mk3 that's been modified a bit

Here's a Lister frame that is similar to the MK2 above

Here's an Egli frame, this one for a Vincent but the concept would work just fine...just a bit more conventional

Here's something fun!

....just a few things to think on.....

Updates!

My intake manifold I'll be modifying came in the mail today - thanks ebay! It's from an MG, which apparently has two intake ports much like my CB450. They are slightly farther apart, which will be remedied by cutting those flanges closer to the carb, not only making the appropriate distance apart, but making the assembly more compact as well. I'll end up losing the vacuum equalization line between the two, but that wont be necessary as I'll be filling and smoothing the vacuum port anyway. I bought a lovely chunk of aluminum to machine new flanges out of for a mere dollar at the local scrap yard.

I've also been polishing some things. I must say, I've polished a lot of aluminum in my life and every time I do it I tell myself I'll never do it again. I hope you like my rustic polishing table.

 

[Herm21]

Man I am very interested to see how you work this out! Great idea, good luck.

 

[panzaa]

Know the feeling about polishing..
Just as fun every time!

But you have to love the result

 

[WeberKid]

been making things shiny:

going well until...

NOOOOO! dimples in the flat face of the right cover!!! Damn you pits and damn my laziness for not block sanding like a me of the future would have done!
In other news, I'm going to the machine shop tomorrow to bring my intake manifold closer to reality. I filed off most of the castings and a giant purposeless block on the back of the right half of the carb flange. Here's a rough idea of what this might look like:

what are you having done at the machinists? Looks like a blast, sand and polish and you're dialed...

I have a retired machinist friend a few towns over who helps me out with anything I need machined in exchange for my young back (heavy lifting, replacing barn floors, shoveling, etc.) I made some intake flanges since the stock ones are a rubber coated steel and cant be welded to the aluminum manifold. Here's a picture!

If anyone wants to read about how I made them, I've started a blog about everything I dirty my hands with:

Sweet stuff! I love your blog, those BBS wheels look amazing!! Really nice to see something like that resurrected like that, what are they going on? I assume a VW by the adapter, but I would love to see some shots of those on a car if you have em.

 

[WeberKid]

Thanks! I've only had it up for a few days, but people are really interested in what I do with my spare time, so I thought I'd start putting it in one place. Not a lot of my friends know how to make stuff, or how much goes into some things. A lot of people here know the ins and outs of a machine shop, so I just posted the final product.
I'm glad you like the wheels. They're going on my 2005 golf. I'm getting tires with my tax return. If you follow my blog, you'll see pictures in no time. The adapter is only so I have a template to redrill the wheels since the offset is so low.

 

[dakine_surf]

Yeah i figured you were re drilling them with only one adapter... too bad you don't have any pictures of the machining, I would have like to see that. I have been contemplating doing this as well... anyway great stuff, keep it up, I as well love the violet color, it really pops on this wheels

 

[WeberKid]

I have a frame and title now. 1966 CB450. I figured it would be a wise investment to save myself the hassle of registering whatever amalgamation I end up with, AND i can take it to the local pre-67 shows when she is complete. I am giddy.

Wow you have a lot of work cut out for you! I just picked up a complete cb450 and it'll be interesting to see where you go with this! Good luck!

 

[WeberKid]

I plan on getting a complete bike without any papers for cheap and combining parts I have made, refurbished, or modified, and tossing them all on my new legal frame, and having a handsome result. that's the plan at this juncture.

hmm...i might have a line on an early cb450 for cheap. i'd have to find out if its still available tho. where r u located?

northeast massachusetts. CBs pop up all the time. I'm not too worried just yet - so long as I'm patient the right bike will surely find its way to me.
