Re: 1972 CB450 "Supersport" Disaster has struck!!!!!

After a beautiful weekend here in the Northeast, I not only got in a copious amount of riding, but a lot work done in the garage.
I ordered the combo Regulator/Rectifier from Oregon Motorcycle Parts.  It’s a nice unit, but large, and I needed a place to mount it. 
I had decided to use Velocity Stacks from Steel Dragon Performance.  Great guys to deal with, and make very nice units.  They come with fine brass screen.  I could not be happier with their quality.












I will be using a Shorai Lithium Ion Battery here, but to check for fitment of the stacks, I have a dead Yuasa in the battery tray.  It’s a close fit, but it works just fine.  Once the Shorai is in there, there will be no clearance/rubbing issues at all.

Since the Velocity Stacks work, I did not need to keep the crossover tube for the airbox which is located under the battery box.  I drilled the spot welds and removed the tube.  However, the attachment for the U-Shaped collar that installs around the frame blocked a good fit for the REG/REC unit, so that had to go as well.  I then drilled and tapped an M6 X 1.00 pitch through the battery box and attached the REG/REC unit.  I only did one side, as the other end was Swiss-Cheese after drilling the spot welds out.  I used copious amount of Thread lock and I am happy with the install.  I will keep an eye on it to make sure it doesn’t loosen up.









Now it was time to move on to the rear fender.  Originally I was going to use an SL fender mated to the Stock CB450 Inner Fender.  I may go back to that in the future, but it would require a good knowledge of TIG welding, which I do not have…  For security, I wanted to retain the mounting points of the stock fender, with a line that flowed with the tank and seat.  It would have required separating the stock fender in to 3 parts – the inner, the Turnsignal/Frame connection point and the inner wire tunnels, and then incorporating the SL Fender.
So, I put on the stock rear fender and decided that I would Bob it.  It worked out much easier, and I think it looks awesome.




The blue section will be cut away




Following the line of the attachment points for the cut





Cutting – I used pinstripe tape to mark where the cut line would be and traced in with black marker so that I could easily see it through the sparks.  I made sure to err towards the scrap section, which could be later trimmed and then finished out.










Stock lined up with the new Bobbed fender.  In the lower picture it looks like one, but the cut fender is on the bike…







Drilling for the Spartco Sausage Taillight




Tailight on, but I needed to cut a block out of the wire tunnel in order to secure the upper taillight mount.





You can see where the hole was made, coming through the channel, but inorder to get a nut on, I had to cut out a section around the hole.  Easily done with the cut-off wheel and the taillight was done.












Me likey!!!!!


The next morning, it was close to 80 degrees and gorgeous out.  I had yet to see the bike off the lift and in the sun, so I put everything on and rolled her out of the shop….













Proud Pappa!










Next week, button up the electrics, send out the speedo for restoration, measure for cables and seal the tank with POR 15.  Getting close!

Anyone know why the pics keep getting messed up?  When I went back to modify, the [img] code had gotten mixed in with an [url] code, and the web address of the photos were duplicated.

Weird...  is it a Facebook thing?

I will be keen to hear from you on how the stock bike performs with those stacks fitted - are you upping the jet sizes?

Thanks Guys!

Unc - I have a CB450 Jet kit from SCI with different jets and such.  With the BCR pipes and SDP stacks I will definitely have to rejet the carbs.

I think she will start OK, and then I will tune her from there,,,

Another major step –

I was able to seal the tank with POR15 and get the bike pretty much wired up.
The POR15 was somewhat easy, but for future reference – do not do this after you have painted your tank!!!!  Fortunately, I did no damage to the finish, but I was sweating the entire time.
To start, I wrapped the tank in saran wrap thoroughly, however no matter how well I sealed up everything, I had leaks all over the place.  What a PITA.  Fortunately, the POR15 Marine Clean and Metal Prep did not mar the paint.  Whew…  I may have slightly etched the chrome on the tank’s side covers, but I think it will polish out – if not, it is not visible unless you are looking for it.
Here are some pics – I was so crazy about protecting from damage, I did not take as many shots of the project as I should have.  I should add that my tank was free of varnish, and only showed some flash rust, but I wanted to go soup to nuts on the POR15 process.


You can see a small rubber “foot” cap I found at the local ACE sealing off the petcock bung.  This worked great, not everything else did…


Green Painter’s Tape for additional protection around the Filler


The PITA rear Crossover spouts.  If the POR15 seals these up, I will lose no sleep


The Marine Clean will be diluted 1:1 with hot water – warm should be fine, I think mine was too hot and messed the tape’s glue…


A rubber chair foot I found at the local ACE with Duct tape attempting to close off the two rectangular “wing” openings for the fuel cap

Anyway, I followed the POR15 directions and in between products I thoroughly rinsed the painted surfaces of any chemicals from the kit.  After the Metal Prep, I took the tank to my kitchen sink and rinsed out all the chemical with hotter than warm water.  I then used a hairdryer to evaporate the water from the tank and let it sit in a warm room overnight.  Not too much flash rust occurred in that time.I then mixed the Sealer, and poured it in.  I spent the best part of an hour rolling the tank around and peeking in the tank with a flashlight and dental mirror to gauge my progress.  Once I had a nice even coat inside, I drained the excess sealer from the petcock bung and rear crossover tubes.  It was a messy process, but I made out OK, and the coating looks good.


Bob’s your uncle…

Onto the wiring:
I used the included connectors with the Oregon Cycle Reg/Rec – a nice kit, BTW.  I cut the four-way connector from the main wiring harness as my plastic was looking pretty manky.  I put the male end water tight rubbers on the main harness followed by the brass connectors.  The females I put on the OCP unit.  For the female connectors, first install the brass connectors on the wires and then install the rubber sleeves – it is much easier.


Nice and neat…


From there, using a wiring harness as a guide, I hooked up each circuit, testing for power and ground where necessary.  Everything went together fine.  The harness has some crappy splices, but almost (I will get to that…) everything works as it should.  I will clean up the splices and replace the15A glass fuse with a modern unit and holder.


Let there be light!!!!!


Tail.  I did have to supply a ground to the fender, and just went off one of the stock taillight mounts

OK, here is the problem.  My Brake light is always on, if I actuate the brake lever on the foot – the light turns off.  Now, the brake system is not set up with fluid yet, so I don’t know how the front brake switch works, and if this is problem.  The Sparco light has only 2 wires, each will light the low beam, but when both have juice, the high beam lights.  What am I missing?

Next week – hooking up the Pamco Ignition, oil gas and light a fire!   Hopefully…

Glad you're back at it, Gersh! She is looking really nice.

Refresh my lazy memory....did you do the Henning big bore kit? Also, did you re-surface your rockers or cams, or did you just go for it?

I'm going to show my "client" (really just a buddy) your build thread as a way to ask permission to go over his budget.  ;D

Thanks Doc!

Yes, I went with the THR Overbore and gasket.  I also tightened up the torsion bars as per Hondaman.

AS for the rockers, I just went with OEM.  However, Cycle Exhange has a great coating that will refurbish your existing.  I woudll have done that had I known about it.  As it is, I will have them do my old ones as spares for this bike and my other 450's.

Hopefully I will have her started this weekend...

Still waiting on my front fender from BCR - but I may try the OEM for stability until then.  The problem is that the fork shrouds may be too wide to allow suspension travel without scratching...

GK,

All that was done was to file everything smooth after the cutoff wheel.  The fender will eventually be sent for fresh chrome plating.  If you are worried about rust, try some of Eastwood's Diamond Clear.  I have not used it myself, but have heard good things.

What are you working on?

Thank Immortal - I am a huge fan of your build.  It came out beautiful!!!!!

So - my electrics are sorted and working - save the neutral light, but I can't really check that until the bike is off the stand and I can check the alignment - hopefully it will work once I get the engine spinning (the bike is definitely in neutral now...)

Brakes are bled and 3 QTS of 15W 40 are in the crankcase.  i will be dry starting her to prime the oil pump and get the oil moving through the engine.

Easy does her, 15 to 20 cranks and then let the starter rest.  Its warm, but not hot at all, so I want to keep it that way.

Updates later on - and hopefully some sweet noise to go with it.   The engine sounds really good on cranking!!!!

Can you tell I am a little ecstatic????

Re: 1972 CB450 "Supersport" Help.... and cross your fingers...
« Reply #318 on: April 01, 2012, 09:03:57 am »
So,

It seems I have hit a major snag last night.  I was turning the engine over using the starter and verifying oil flow via the oil spray on the dip stick.  I would take out the stick, clean it, re-dip and verify that the oil level was remaining OK.  I assume from the fact that oil would then be all over the shaft above the check line, that oil was indeed coming down from the upper engine.

After about 2 hours of this, I hooked up the throttle cable and then my auxiliary fuel tank to the carbs.  My left side bowl was leaking at the screw - so I will need a new o-ring there, no problem.  I replaces it with on off my '69, and no further leaks.

I then tried to get her started.  No go, no sign of life.  She was getting fuel and air, so it must be spark.  It was, I had a bad connection which was not supplying power to the PAMCO ignition.  I remedied the connection, and made sure there was spark at the plugs, and that they were indeed gapped correctly.

I then tried to start her again - keeping a low amp 12V battery charger to keep the power strong, and making sure nothing was getting too warm. 

Cranking, I heard signs of life, but no go.  I would let her crank for a bit and then back off to let the starter cool down.

All of a sudden, the starter and K/S are not turning the engine anymore.  Before I lost my mind, I walked away, as we had a dinner date with friends.  This has been bothering me all night.  Did the CAM chain snap?  I am headed down to see what is going on, but any insight/advice is greatly appreciated.

Keep your fingers crossed....

Ugh - I am going to be ill.

The CAM Chain has somehow come off the lower crankcase (I think).

I removed the chain tensioner and rotated the engine via the crank bolt on the alternater.  The lower spins fine, but the cam chain is not engaged, so the upper cams are not spinning with the pistons.

Looks like the engine has to come out and the top end checked and rebuilt.

I am sick to my stomache.

Any advice?  Potential nightmares to be encountered?

Ugh - I am going to be ill.

The CAM Chain has somehow come off the lower crankcase (I think).

I removed the chain tensioner and rotated the engine via the crank bolt on the alternater.  The lower spins fine, but the cam chain is not engaged, so the upper cams are not spinning with the pistons.

Looks like the engine has to come out and the top end checked and rebuilt.

I am sick to my stomache.

Any advice?  Potential nightmares to be encountered?

Oh man that sucks , havent seen this build before , it looks absolutely fantastic , really one that will stand out fom the crowd , you should be able to take the topend off without taking the engine out (i think ) .
Fingers crossed it will turn out easier than you fear .

Thanks Emo,

I have been watching yours as well.  Looking killer!

I don;t know about getting the top end off in the frame, but I am ready to pull the engine for inspection as to what happened. 

I don't think I can go back to NYC for the week with this gnawing at me....

I feel for you. My 350K just blew up for the second time after a professional rebuild. Don't know what happened this time and I don't care. It hasn't given me a thing back and I'm done with it.
I do sincerely hope for the best for you though!
If it's worth doing at all it's worth over-doing.

Aw man that sucks. I know his careful and methodical you are with your work so I figure it must be a parts failure rather than build error.

Try and get through the week and you will back to solving the snafu in no time.

Do you get four days off over Easter to work on it?

Thanks Guys.

Unc - I would not bet on parts failure - I must have missed something.  I don;t get the time off, and I have my Mom, Brother, Sister-In-Law and Nephews up all next weekend.  I am hoping to get some answers tonight.

I will keep posting, and enduring....
