My CB200 Build - AKA "Incognito" - UPDATE MARCH 21 - VIDEO PROOF THAT IT LIVES

Re: My CB200 BUILD - THE END IS NEAR - PROJECTED DRIVE DATE JUNE 3

Hey, thanks for the heads up, do you have any pics of the carb insulators I am looking for, so I have a baseline. Or know of any mods that could be performed? I do have longer studs already. So that shouldn't be a problem. Did this bikes originally come with insulators on them?

Well Slokrt, that definitely gives you more time!
 
Re: My CB200 BUILD - THE END IS NEAR - PROJECTED DRIVE DATE JUNE 3

I stole these photos from eBay listings.

Here are the original CB200 manifolds:

What's nice about them is that the center section is rubber so there is no thermal bridging between the head and carb. They also have vacuum taps for syncing the carbs which is nice. If you search 'CL200 manifold' on eBay there are a couple sets for like $60.

Here are the CB175 insulators:

You will also need the gaskets that seal them to the head. I traced the outline of the insulator on some gasket material [from AutoZone] and cut it out with an Exacto. With these you still get thermal bridging through the studs but it must be negligible since that's how the 175s came from the factory. I was able to drill my set of CB175 manifolds and install vacuum taps.

Hey, thanks a ton for that information! I will be picking up a set and hopefully have it sometime this week!
 
Re: My CB200 BUILD - THE END IS NEAR - PROJECTED DRIVE DATE JUNE 3

For cutting the gasket, do I cut it so that the oring still has contact with the engine? or do I cover the oring with the gasket?

next project......


Converting this 1916 harley replica into a bordtrack racer!

Well here are pics of my seat, temporarily upholstered. It is upholstered with an old set of jeans for now. Going to go to leather or vinyl when I break the bike down for powder this winter.

I also made my own LED static timing light. I'll let you guys know how it works.
 
Re: My CB200 BUILD - THE END IS NEAR...... DRIVE DATE DELAYED

dig the bugle boy seat. I need to make a light like that seems simple enough. I did my timing with an ohmeter was a real pain
 
Re: My CB200 BUILD - THE END IS NEAR...... DRIVE DATE DELAYED

Oh yea, I bet that was a pain! Making the light was really easy, just bought some alligator clips and cut the pos and neg wires in the flash light after the switch and hooked it all up!

Click to expand...

This is the order of assembly:

HEAD - FLAT GASKET [that you cut] - PLASTIC INSULATOR - O-RING [sits in manifold groove] - MANIFOLD - O-RING [sits in carb groove] - CARB

If you haven't already come across this - you can access the old Honda parts microfische on websites like BikeBandit.com and www.cmsnl.com among others. It's been hugely helpful to me when I'm trying to cross-reference parts between bikes or figure out what parts I'm missing.
 
Re: My CB200 BUILD - THE END IS NEAR...... DRIVE DATE DELAYED

Well for anyone else who has the same issue as me.... lack of insulators... there is good news! You can make your own. After looking around the internet for "how to make your own carb insulators" and coming up with nothing, I decided to give it a shot myself.

Materials I used

High temp silicone gasket - melting temperature over 1000 degrees
Pvc plastic - Melting Temperature 450 degrees - ignition point over 500 degrees

Highest safe operating temp on any engine should not be more than 350 degrees


So I used my carb boot to trace an outline of what I needed onto my pvc.
I used 1/4" pvc plastic and used a ban saw to cut out the outer shape, which was drawn with sharpie.
I then used a drill press to drill all the holes I needed in my plastic insulator
I then used my carb boot to trace out my shape on high temp silicone gasket material.
I cut out my gasket (2) for each boot, using a razor blade.
Then I used a hole punch to make my holes in my gaskets where I needed them.
I put on my longer engine stud bolts
slid on one rubber gasket, followed by pvc, followed by another gasket
Then I put on my carb boot
Followed by one locking washer and finally the nut.

I will report back as to how it works, however it should be sufficient!

Thanks to copperlite for the useful information!
 
Re: My CB200 BUILD - THE END IS NEAR...... DRIVE DATE DELAYED

Well after rummaging through the box of old parts that the PO had given me.... I found.... The original cb200 carb boots! I will probably fix those onto my bike if my mod gives me some problems.
 
Re: My CB200 BUILD - THE END IS NEAR...... DRIVE DATE DELAYED

Nice build and keep it up. Small world I guess since I saw you talking about where you live and I went to Dordt and all. I know a lot of people around there.
 
Re: My CB200 BUILD - THE END IS NEAR...... DRIVE DATE DELAYED

Wow this is a small world! I am redoing the roof on the alumni house of Dordt starting June 12th!
 
Re: My CB200 BUILD - THE END IS NEAR...... DRIVE DATE DELAYED

If you end up not using the stock controls, let me know. I'm trying to track down the right side controls for my girlfriend's 200.
 
Re: My CB200 BUILD - THE END IS NEAR...... DRIVE DATE DELAYED

Will do, but I believe my controls are from a cb175.


UPDATE: Piston Rings Should be in sometime this week. My new goal is to have it running by June 9th.
 
Re: My CB200 BUILD - THE END IS NEAR...... NEW DRIVE DATE June 9th

Okay! So I have my motor put back together, and have almost everything done.... But can somebody draw me a labeled diagram of where the two coil wires go to... One goes to the spark advance... and the other one I do not know. This is causing me some frustration as I am getting now spark. Any help would be great!
 
Re: My CB200 BUILD - ENGINE BACK IN FRAME - COIL QUESTION

Okay, so I have spark now! Hooray.... But I sitll can't get my bike to turn over... Does anybody have any methodical tips for getting it to turn over after a top end rebuild. Thanks
 
Re: My CB200 BUILD - END OF BUILD PICTURES

I got the engine to fire up! Now just to tune it and I will be able to ride!
 
Re: My CB200 BUILD - END OF BUILD PICTURES

That things look clean! Did you clear coat all those little engine bits after you painted them?
 
Re: My CB200 BUILD - END OF BUILD PICTURES

Yes, I used high temp clear coat.... But ideally I will break it down this winter for powdercoat.
