Forgot to mention that I cooked the rubber carb boots in some wintergreen yesterday.  Turned out pretty well.  The boots from the engine to the carb got soft enough to mount, but I wouldn't say really pliable.  I used 1 gallon on water to 4-5 oz of wintergreen.  The trumpets however became very floppy.  I only had them in the solution for about 20 minutes.  I would not suggest doing the trumpets in the solution.   The rubber got very slimy and started to ball up.  I used some steel wool and an old tooth brush to knock down the lumps and smooth them back out.  The other parts spent a full hour in there.  After they were done cooking I dunked and scrubbed them in some warm water to try and release some of the wintergreen, but I don't think it did much good as my garage reeks of it.

I hunted my local area to no avail so I bought my stuff off of Amazon.  Buying it the way I did turned out to be much cheaper than the little bottles and I have enough left over in case I need to do it again or someone local needs to do there stuff.

After I was done cleaning and drying them they popped right onto the engine.  I aligned them with a straight edge then pushed on the cars.  It only took a little bit of umph to get them on and seated.




I also received my turn signals today.

Hey I ordered Hagon's today as well! In fact I just got a tracking number from them. What great customer service from them.

I have re-read through your thread but didn't see what size rims and tires you used. Can you post that info? I am going to be plunking down cash for rims and tires and looking at options now. I like yours.

Hmmm...I didn't get a tracking number.  But now that I think about it I didn't provide an email addy either.  About what time did you order and what is your expected delivery date?  Maybe you were the reason the phone was busy when I first tried calling this afternoon.

The rims were from a 75 GL1000.  19 x 1.85 front and 17 x 2.5 rear.  I went with a set of Avon Road Riders.  The front is a universal (can be used for either front or rear) 100/90 and the rear is a 130/90.  I liked the sportier tread pattern.

I called at about 9:30am pacific and I did provide an email. Expected delivery is next Tuesday via UPS ground.

GL rims huh? I never thought about that. They look great. Did you buy them used?
I have those Avon's on my 78F and love em. They handle great and look even better.

That was right at the time I was calling on the East coast.

I did buy them used.  I got a smoking deal from a local guy I found on the Naked Goldwing forum.  I bought the entire front end and the rear wheel for $150.  Check out that forum.  There are some pretty cool cats over there.

I can't wait to try the tires out.  I am pretty much over just pushing the bike in/out of the garage.

Just curious as to why you chose Hagon shocks.  I am trying to figure out which shocks to purchase for my next project.  Racetech and Works look great but will likely cost near $800.  I think (from memory) new IKONS are somewhere around $200-$300. 

I'd like something that offers good performance, but doesn't break the bank.

Very interesting build. Can't wait to see it all come together. I love the color scheme of the engine and especially the custom dial faces!
'73 CB750k engine, hubs, and a '76 tank, on 'a 78 frame. Go figure.

I chose the Hagons based on the good reviews here.  Like you, I wanted something that offered good performance that wouldn't break the bank.  While it would have been nice, I didn't need something with lots of adjustments.  I am not going to be racing the bike.  JUst some commuting and the occasional back road strafing.  I went with Dave Quinn because he offers two free spring changes if they aren't to your liking.

ARRGGGGHHHHHHHHHHHHH

I have just spent the last three hours trying to get the air cleaner on.  I absolutely can not get the rubber boots that mate to the carbs on.  I can get one side on, but when I tighten the clamp I can see the boot slipping off the the carb.  I leave it and try to get the center two all the way seated.  No dice.  I take the boots out of the air cleaner to attach them to the carbs...and they just slip off when the clamp is tightened.  I just don't know what else to do other than buying new boots and give them a try vice my wintergreened set.  The boots for the engine to carb went on great.  I have tried having the angled part on the top and bottom, but the result is always the same.

On a good note I received a lot of parts today.

When I failed I looked on the interwebs to see if there was some trick to getting them on.  Some suggested attaching the two center ones to the carbs and then trying to slide the top half of the airbox in and seat it that way.  Still no dice.  I think I may have gooned them up when I cooked them in the wintergreen.  They are really nice and supple but the ends that attach to the carbs just don't have the nice squared off edges anymore and the ridges don't have a lot of sharp definition to them.  It is almostlike they smelted together a little bit.  I remember when I took them out of the pot that they were slimy and some of the rubber kind of balled up and rubber off. 
 
I said to hell with it and just ordered a new set from a guy in Germany.  I found his ebay page through the Honda Chopper site.  They seem to be impressed with the quality and his cost is cheaper than anywhere else I have seen including shipping.

It is the old crappy rubbers

I tried to bring life back in to them and the airbox ones just don't work like the carb manifolds. Mine got slightly slimy and discolored too. They were nice and soft but they don't fit right, they shrink up in size. If you compare your new ones to the old you will see what I mean. The diff is pretty surprising

I  heared of cooking the boots before but never tried it. I soak anything rubber in a zip lock freezer bag with a bit of simple green in it, and that has always worked for me without adding any heat to the rubber until I install it ,then it is only a hairdryer, haven't ruined a piece this way yet.

Well it has been a while since I updated anything.  I have been getting beat up with the wiring.  Trying to adapt the Triumph hand controls to the CB is a bit of a pain.  I think I may have a pretty good handle on it now, but I still have some small issues.

When I flip the switch for the hi/lo beam the dash light and headlight flash, but they revert back to lo beam.  Not sure what would cause that yet.  Not sure if it a wiring issue since it does attempt to change, but I will look into the schematics again and see if I missed something.  I did wire in a rocker switch to be able to turn the headlight on/off just like the stock hand controls had since that option is not available on the Triumph controls.  Before I put in the rocker switch I just jumpered the wires and it seemed to work.  The light output was very dim since I was only running it off of the battery charger, but at least the dash light stayed on then.  I will go back to the beginning on that and find out what is causing it.

I did prime the oil pump and get it installed.  Filled the tank with oil and put a little in the 1&4 tappet holes.  Used the kickstart between 80 and 100 times then went to the electric starter.  Pressed it for 5 seconds and released it then waited 30 seconds before doing it again.  On the third try I noticed the oil light go off on the dash and when I looked down I had 65-70 psi on the gauge.  I did this a few more times and was very happy.

Fast forward two days and I go to the garage last night only to find a nice puddle of oil under the bike.  It was leaking from the connection at the supply line and oil tank.  I used all new OEM crush washers.  So I have a bit of troubleshooting to do to find out why.  I hope the flange on the oil line isn't cracked.

I also had an issue with the turn signals not flashing.  That ended up being a bad thermal flasher unit.  It was internally shorted.  A trip to Autozone, $13, and a new EP35 electronic flasher and they flash as advertised.  I am not running LED turn signals so that was not the issue.  Hooked up the brake light and it works as advertised.

I have installed new rear shocks, rebuilt the front end with new springs, routed all new cables, replaced the brake pads, and have a new exhaust slipon on order from Cone Eng.  I had to swap out the gauge mount from the 750 one to the GL one because it caused the sppedo and tach cables to be put in a bad bend.  That meant re-doing some brackets to adapt the gauges to the mount.

I received the new airbox rubber and installed them.  They slipped onto the carbs with ease.   I did have to pull the carbs and adjust the boots there to allow the airbox to mate with the tabs on the frame.

I am getting close, but need to figure out the headlight and obviously the oil leak.

A couple of pics of my gheto rig to suspend the front end while I replaced the springs.  My front lift stand isn't tall enough to lift the front end off the ground so I had to improvise.  My garage is framed with steel beams so I just lashed a ratchet strap to them and then to the bike and up she went.

I am kind of still undecided on paint.  I know the colors (same as the blue and grey powder coat), but not sure on how I want to apply them.  I was thinking a blue tank with a wide grey stripe down the center the same width as the dash panel with two thin grey stripes on each side.  Or I might reverse the colors.  The side panels will be whatever main color I go with on the tank with the same accent colors.  I have something planned for the center of the panels that I don't want to disclose yet.

Oh trust me I wish it was rideable.  Hoefully I am not too far away from that.  I just booked my cabin for Deals Gap in June and I would really like to take it up there.

If you're thinking stripes, here's the way I went... silver tank, off white HONDA badge, black/ off white (same shade as badge) stripes.  I'm still not sure about the chrome trim around the tank.  I'm not even sure where I'd find the stuff.  I may just reupholster the seat without the chrome.

Maybe these will give you an idea wether or not you want to go in this direction (with your colors of course)...
