1971 CB500: Project "Yokai" - Lots of Pics
« on: November 22, 2010, 09:14:52 PM »
Hey everyone,

I have been working on this CB500 for a few months and have been lurking this website for a while now.  I picked up this CB500 from a guy that has about 200 old bikes that are just waiting to be restored.  A bunch of old Suzukis, Kawasakis, and a lonely 1971 CB500.  I picked up the bike for $300 bucks.  The cylinders turned freely but there was no kickstart and the electric was a mess so I was not sure if it ran.  It literally sat in a field for years so there was plenty of rust and things to be replaced.  I was trying to think of a name for it and came up with "Yokai."  I'm half Japanese and since Honda is from Japan I thought it would fit to give it a name to match.  Yokai means monster in Japanese.  





The teardown went pretty slow since this is my first bike.  I have never really worked on a motorcycle before so am having to figure things out as I go and learn from this forum.  I'll be asking a lot of questions along the way so be prepared to help me out!







The first mistake that I will never make again was not powerwashing the bike before I started.  I should have sprayed everything down to make my life easier later.  The second big mistake that I made was tearing everything apart before I found out if it ran.  Rookie mistakes.  I'll just have to get everything back together and pray that it starts.  


Frame totally stripped down.

Next, I ripped the carbs apart.  I cleaned the hell out of these and it took me way longer than it probably should have but they are looking good now.  


Nasty!




All 4 carbs look like this now.  I got them cleaned up and painted them flat black.  

I got all the parts back from the powdercoater and they turned out great!  I had everything done in textured flat black.  The overall vision for the bike is flat black with 2 high gloss racing stripes and a gloss Honda logo on the tank.  




Swingarm is back on the frame with new bearings.  I also got some new rear shocks.  Starting to look more like a bike.  


The powdercoater had a great idea.  He taped off the numbers on the frame and after he put a clear coat over them.  They look great!  I don't think there are many bikes that have that feature.


Both kickstands.  We'll see if I end up using both.  


Rims were done in the same flat black.  Spokes are on their way so hopefully I'll have some finished wheels by next week.  

I had the fork lowers done as well.  Same color.  I think they turned out great with the brakes and the polished adaptor.  



Also, shout out to member Pampadori at Slingshot-cycles for the new brake lines and pipe.


I want to drill the rotor.  I have some patterns but am open to suggestions if anyone has any.  

New rear brake shoes to replace the nasty rusted ones that were one the bike.  The mechanism that expands the brakes was really rusted so it took some work but everything is working now.




Last but not least for tonight I got part of the triple tree back together.  I put in new bearings from All Balls.

Fork tube question
« Reply #1 on: November 22, 2010, 10:35:53 PM »
I do have one question.  I need to get some new fork tubes as mine were pitted and rusted beyond belief.  Do I have to get original CB500 fork tubes or will other models fit as well.  Where can I get new tubes at all? I heard Honda doesn't make them anymore.

The folks that run the place must be at least 100 years old (or so it seems when talking to them) but you will love the quality and you can even order custom lengths with only a slight up-charge.

Batman's 500 !! Looks good so far!


The 500 tubes are different then the 550 tubes (internals and length) so you will have to track down a set from another 500.

You can get new 500 forks made by these guys if you're looking to go that route, I just got a set and am very happy with them.

What did you do to get the interior passageways of your carbs as clean as the exterior?

What did you use?

Nice looking build

Yokai is looking great. You've made lots of progress in only a few months. Keep up that pace, and you'll be riding his spring!

I think Im actually going to get it chromed.  I just wanted to put it on as a mock up so I could see what it looked like.  So much to chrome, so little money...

I stripped everything off the carbs then soaked them in a carb cleaner bucket.  After a long soak I used an air compressor to blow out all the holes.  I used a spray carb cleaner after that with the smallest pipe cleaners that I could find till everything was looking good.  Good luck!

Yeah the tubes were like 259 or something plus about 25 for shipping.  They are way old school and have you pay the UPS or FedEx driver when they are delivered with a money order or a cashiers check.  The total will be a little under 300 I think.

Yeah, most of my projects end up wearing Frank's tubes:

Also, There MUCH stronger then stock forks.

BTW; I think the brake junction looks fine as is.

Alright so I'm trying to figure out what to do with the engine.  Should I go flat black or silver?  Also, has anyone powder coated the engine or do most people use the high temp rattle cans?

I'm a fan of the stock silver but that's just me.

General concenses is powder coating is too thick and may affect cooling. I've rattle canned two and the first after 7000 miles has held up really well. The paint could have kept going but the rings couldn't :)

Any color you want..!  Me... I like the classic Silver but if you asked Spiky bike, he'd say Bright Freeking RED!

Whet ever you decide, I suggest using this stuff:

A lot of members have had very good sucess with either the Duplicolour, or VHT engine paints.  The key, as with any paint job is in the prep.
