Well the mad dash seems to have paid off in some nice looking bits!

Stopped by a cerakote shop today.  He wants $70 to do the headers.  I think that is fair.  I was also able to look at some of his powder coat chips and I think the color I was looking at to do the frame in will work nicely.

Spent a little time this afternoon putting the lower half of the engine together.

With the guts in it.




Case halves assembled.

I received some confirmation that the missing piece on the right outer engine stud as viewed in the 3rd picture above is only there to quell some vibrations.  So I set forth last night to assemble more of the engine.  I am changing out the stock cam chain tensioner wheels for a set of picked up from a guy in Poland.  He makes a metal gear wheel to replace the stock smaller rubber wheel.  Somehow when I was futilely attempting to drive out the center rivet I managed to bugger up the whole thing.  So now I am in the hunt for a replacement.  I can still continue to assemble all the stuff that goes on the sides of the engine, but what a disappointment.

I thought for a bit that I may have kept the tensioner from the wife's bike when I installed a KA slipper, but I guess I threw it away.  I have sourced a replacement though.

Figured I would install the clutch basket, primary drive gears, and oil pump.  Well that came to a screeching halt due to the incomplete gasket kit.  It is missing the oil pump gasket.  So the engine is officially done until I get some parts in.

Since I was at a stopping point I decided to do some cleaning of parts that way when I am ready for them I can just install them and go.  Well the hits keep coming.  I think I figured out why the PO could never get the bike to run.

Well now I am not sure mine is bad.  I was looking last night and found this NOS.  The wire not being connected looks a lot like mine.  I did some quick measurements this morning before heading to work.  A-B=.7 ohms  B-C= 1.1 ohms  A-C=1.7 ohms.

The good and the bad tonight.  Checked the stator when I got home and it is indeed good.  Well at least it ohms out good.  My local dealership had a oil pump gasket in stock.   They actually had three and the last time they sold one was 1987.  They have done their annual inventory every year since then and accounted for them.  A whopping $1.01 a piece.

Managed to get the clutch basket, oil pump, oil slinger, and stator installed (in the cover).  However, when I went to put the cap on the oil slinger I couldn't get the snap ring to seat fully.  Then I took a good look at it.  Sometimes I will never understand people.  Whoever was in the engine before decided it would be better to grind down a snap ring vice getting the correct one.  So another part I have to go get.

Received my replacement cam chain tensioner wheel and was able to remove the rivet without boogering it up this time.  A co-worked made the mandrel last night for me so I can set the rivet.  Tonight I should be able to assemble the tensioner which will allow me to finish assembling the engine.  Tracking shows the snap ring is at the post office so hopefully it will arrive today.

All the parts I needed finally came in so I was able to finish assembling the engine today.  As expected getting the rocker boxes on gave me fits, but I managed to get them on.  It took a few tries though.  The first two times I couldn't rotate the engine through two complete revolutions.  It kept locking up for some reason.  The third time was the charm though.  To make sure I must have rotated the engine half a dozen times to make sure it wasn't a fluke.  All that is left is to set the cam chain tensioner and adjust the valves.

Set the CCT and adjusted the valves today.  The engine is now complete except for installing the electronic ignition, but that has to be done after the engine is installed in the frame.  The engine is now in a lawn bag and put away in the corner.

So I am not much for sitting around.  Ordered the gauge overlays then proceeded to tear open the gauges.  The tach gauge was in fantastic condition.  The speedo...not so much.  This is going to take a lot of work to get usable.

I got the speedo gauge all cleaned up last night.  After I removed the corrosion with the brass wheel I applied a light coating of phosphoric acid to the metal surfaces and let it do its thing for a little bit to help seal the metal.  Lubed all the gears with some white lithium grease.  Not sure if the damper needs the RC car silicone grease yet or not.  Tonight I will hook up the drill (in reverse) and see how she functions as well as get some pics.  Still gotta see what I can do about brightening up the tenth mile wheels since they are a bit yellow.

Tested the gauges tonight and they work flawlessly.  The damping rate is excellent so no need to go any further with the dissection to put some silicone grease in the pots.  I ran them for about a mile varying the input speed.  That takes a surprisingly long time with a cordless drill.

The gauge overlays were delivered today and I was excited to get home and put them on.  They aren't the correct ones.  They are for a CB350F not a CB350K.
