That has to be the kookiest looking 400/4 around.

Or does anybody know different? 😄

Love it!  Can't wait to see the rest of the restoration!

Do you have specific parts vendors you like to use, or is it wherever you can find stuff?

Haha, thanks.  Inspired by this silly Rat Rod trend happening here now.  Plus I still get to ride while collecting clean parts.

As the weather is still pretty cold Ive only had the chance to take her out a couple short rides. 

I have restored several old Hondas now and this one was by far the most fun to do.

She has been nominated and currently in the running for Do The Ton, Bike of the Month contest.  haha

Thanks so much bud.  And I cant hardly wait to finish the proper restoration, next winter.

Most has come from David Silvers, these little machines are kinda, sort of rare here in the States.  (as Honda models go anyways.)

Most of the used parts for sale on Ebay here are for the most part junk and $$$.  So most has come from abroad.

Re: The Black Knight...Seat and Rack re-DO.

Tossed the chrome rack aside.
Made my own, then shortened seat and moved rack forward 7 inches.

Re: The Black Knight...Dialed in and ready to ride.

I started getting fast idle issues.   Sorta like a vacuum leak but not really like a vacuum leak.

Julie and I compiled a list of things to check.  Thanks Lady.   ;)

First was plugs and caps.  They were fine.

So I made a pair of more substantial links, as the originals were bent.

Installed and re-synced then tuned A/F mix.  I found it too lean.  So with 3/4 turn in...

Viola, The fast idle calmed right down, now holds a smooth and steady 1200.

For fun, I installed a Dyna DS1-1, got her dialed in w my stroboscopic light and just like that she's done and ready for summer adventures.

Still need to flip that pesky #1 header clamp.   ::)

So the bent links were the cause of your fast idle problem?  Do you know how they got bent (I don't recall that you dismantled your carb rack enough to remove those links)?

Yeah, sorry I ddnt bother to add the pics.

I took them completely down and changed all the o-rings on the fuel feed pipes.  Thank goodness, as I found the center T fitting still full of debris.   

Actually I bent them, being a brute during the first sync.   ::)

The fast idle problem was the combination of Lean A/F mix AND the sync.  But mostly A/F mixture.

the first one I turned in #4.  the idle really took off, faster. 

(Which is exactly what you want it to do.  As A/F mix is properly tuned in at fastest idle.)

So I knew I was onto something.  Cranked in the others.  Then went through and dialed them all in/out for fastest idle properly.

Afterwards, I re-adjusted idle speed for 1200rpm.  Running smooth as silk.   :)

Also mattsz, here's some pics I did take during.  Not the best as sometimes I get lazy about it.
 



Debris stuck in the T fitting, even after ultrasonic.




Rotten o-rings.




New on the left, old and flat on the right




Best to disassemble carbs as theres plenty of places for debris to get trapped in the fuel feed galleys.




I also found one float was a half gram heavier than the other three, so I replaced it w a spare that averaged same as the others.

Pulling and swapping that #1 clamp was a PITA!!!!    :P

Everything went back together as it should, but if theres any leaks I will probably have to drop that darned oil pan to get everything properly aligned and torqued.

Thanks for the details re. the carbs.  I'm going to do my best to clean mine "on the rack," then reassemble.  I haven't run the bike yet, so I still don't have a baseline performance.  The bowls and accessible bits within them are pretty clean, so I'm keeping my fingers crossed...

Ten 4 man.

If I hadn't had the leaks I wouldn't have torn mine completely apart.

Rach and I had our first sunny ride of the season.

It was almost a success.  The circlip popped off and my shifter was left dangling by the rearset linkage out on the breeze.

Got home, drilled a hole through the shaft and fixed that.

Looks like a nice sunny day where you are? Good to blow the winter cobwebs away. Shame about the circlip going AWOL, did you have the washer fitted between the circlip and the gear pedal?
It's been a great sunny day here as well, I'm just back from a 170mile ride out with the local institute of advanced motorcyclists. I've just joined them, a really great bunch.
That Hawk looks nice, imo they look so much better than a Superdream that followed it.
