First post. Second bike.

Okay so I sold my first project called Silvia the other day. She is a CB400N from 1981. Took 7 months, spent quite a lot of money but learned a great deal. I didn't plan on starting on a new project right away but I couldn't help myself when I saw this CX500C - 1981 for sale. I had to buy it. Building a cafe racer from a CX has been on my bucket list for years. Silvia was practice, and this is the bike I'm building to keep, for years to come. It's going to take the time it takes and I'm willing to spend the money to make everything just the way I want it.

Brought the bike home today and we started to take it apart right away. For a 36 year old bike it is in great condition but everything is gonna get cleaned, painted or polished in the following weeks/months. My plan is for it to look as nice as when it came out of the factory in -81 and run better than ever before.

When the donor was brought home I sat and looked at if for half an hour. Planning what to spend money on first. Bought a ton of things, I’m gonna keep it a secret for now but you’ll see. I’ll just say this, after a couple of hours of shopping online my bank gave me a personal call asking what the hell’s wrong with me basically. They saw an alarming amount of paypal expenditure in a short period of time haha. Anyhow, I’ll post what I bought as it shows up!

Everybody, meet Harper.

Welcome aboard, take a few minutes to update your profile Forum settings (link below). I see the bike is not a US version, but in pretty fine shape. I suggest you get all the kinks running wise first, and assuring what it is as was designed. They are a blast to ride as built. I don't quite get all this cafe' "racer" thing, and hate to see a very nice specimen torn up just for that. Better to wail away on a duffer project, IMHO.

With the caveat regarding the mayhem PhotoBucket has foisted upon the inteweb, many of my other helpful links below will likely have broken links to pics. However, glean what you can from the WIKI, it still has a ton of things to help, as well as a free FSM to download. Be sure to get the applicable addendums.

Look forward to seeing where you go from here.

Thanks for the tips!

that is a interesting repair it comes from the front cover being cracked at the oil drain plug

i wonder what the plan was to change the oil

or if they used a marine suction pump down the dipstick

or if they did this and sold you the bike?

Been a productive day today! Cut the shock mounts and cleaned up the frame a bit.

Wet sanded some parts. I want a mirror finish on the clutch cover. Any tips?

Started welding the battery box as well. This will fit under the frame, where the hbox used to mount.

Cut and tacked tubing for the frame. Ordered a Hookie seat hoop
with a integrated led light that I'm going to weld later. Should arrive in the next couple of weeks. My new shocks should come around that time also. When everything is welded and done the frame will be sent for powder coating!

Today I continued cleaning the engine. Should get my gasket set and new stainless bolts for the entire engine soon, looking forward to that!

My plan was to use the original front fender, just cut it from either ends making it shorter. Then i noticed that I could weld the end pieces together instead. Tried it out and it looks pretty cool. Ran out of argon when welding unfortunately so I'm gonna have to finish that up another day.

I would take a braided line straight from each caliper to the master cylinder. Done this on a couple of bikes and it makes for very easy air purge.

They're not going to reach all the way to my master cylinder. And I'm not planning on replacing the hoses. Otherwise that would be a good idea!

Okay, so a T-joint like the one you linked would work? It does not have any other function than splitting the fluid, like regulating the pressure or something? Also, it said M10x1.0. Pretty sure my bolts are M10x1.25. Would I have to buy new banjo bolts also?

The OEM botls are 10x1,25mm
If You buy a splitter with 10x1,0mm You will need three new bolts.
And check to buy shorter ones.
The OEM bolts will be to long.

Don't forget to buy new copper or aluminium sealing washers.

Degreased the engine and started preparing everything that's going to get powder coated. Will replace fork seals and in both wheels so took the old ones out. Got some stuff in the mail also! Bars, headlight bracket, speedo, tires, master brake cylinder and engine gaskets are some of the things I got.

Once I get my seat hoop in the mail I'll weld it together and send everything for powder coating!

That speedo only goes up to 140km/hr!! I am often over 160 on mine LOL. I should probably start acting my age!!!

I got a set of those Shinko's off a Harley mate real cheap who had ordered them online to realise he only had an 18" front wheel and would not fit. Mine will be fitted Friday before I take my bike home. My rear is the white wall version which could look a bit wierd on my GL mags!!! Guess I see how it looks and if necessary get out the tyre black
