Topic: Mayble's Tale......time for some upgrades

[Desert-SOHC]

I've gathered almost all the parts to do my dual disc using CB parts.  Today I scored a 76 Hondamatic aluminum rim wheel complete with axle, speedo drive, and rotor.  I still need to get some hardware and I want to send the rotors in for drilling, truing, and lightening first.       As soon as the matic wheel gets here I'll pull the rotor and send it out.  I also have new brass swingarm bushings and an all balls kit for the steering head.  Been trying to wait till the rainy season, but it looks like my rear tire is going to be bald before then so I'll do the swingarm bushings when I replace the rear tire.

Nice work...you going Shinko rout on tire?  Or Michelin, Bridgestone, Dunlop, Continental, or other?

[Desert-SOHC]

I have a Shinko on the front so I will go with it again on the rear and go higher end on the next go around.

I have now gathered enough parts to warrant downing her and wrenchin.  Just got another set of reproduction carb rubbers and OEM air horns and new SS clamps for all (eww...shiny).  Also have a set of brass swingarm bushings and an all-balls steering head kit to do along with a new rear tire and change out the front wheel for the aluminum one.

Ok, let's get started!  What first, front back or middle?!

Remember, when eating an elephant, one does it one bite at a time.
Are you going to weigh the bare rim to see how much weight you are shaving off with your change to the Aluminum rim?  Is it a GoldWing or aftermarket Excel, Borrani, Sun, etc?

Have you used the Vetter bags yet?

The wheel is from a 76 CB750A, not concerned with weight savings, just like the look of the aluminum wheels over the steel.  As for the bags...I use them all the time!  Being in southern Cal, she is pretty much my DD and this time of year it will go from 60* in the morning to 85* and back to 60* while riding.  If I decide to pop up to the mountains to see some friends it may be in the 40's before I leave, so I carry a WIDE variety of gear in them and I regularly go grocery shopping with her...she's good for about $120.00 worth of groceries in the bags...

She has been running horrible of late and has been pretty much unrideable so today I tore her apart and tackled the carbs and related rubber components.  I've been doing a lot of reading and research on the PD's and how they work and have come to the conclusion that my idle circuit is to lean causing most of my drive ability issues.



With them on the bench I went up to 38 idle jets from 35's, changed the needle clip to the center position (77 needles), and went with 118 mains.  I don't know how, but my floats were WAY OFF, so I readjusted them to 12.5 mm, verified my accel pump squirt was good, and reassembled them.  Next I replaced the manifold rubbers with aftermarket ones that I found from Japan, the ones I bought 2 years ago are pretty much junk with cracks showing on all of them in between the clamping wells, causing all sorts of issues.  The air cleaner horns were in worse shape than the manifold rubbers, almost to the point of starting to fall apart.



Replacing the manifold rubbers was straight forward and easy as was getting the carb rack to pop on to them.  The air horns were OEM's and fit like a champ.  The reassembly of the system went smooth overall with a bit of arguing from the air cleaner assembly.  Double checked EVERYTHING for fitment and seal and tightened the SS clamps on all.  Turned the fuel on and checked for leaks...none,  1 twist, full choke, and she burst to life again, sounding MUCH better than before.  Let her warm up and took her out for a small shake down.



I was nice to her for 10-15 miles, letting her warm up all the way with a leisurely buzz down the frontage roads.  Went back home and readjusted the mixtures from 1.25 turns to around 1.5, she seems to like it there and she idles smooth at 1100 rpm, I can get her down to 1000 rpm but that's a bit choppy, need to vacuum sync the carbs.  Went out on another test ride and rung her out, with good results.  I have no weird hesitations off idle anymore and she pulls like a freight train to redline...okay maybe not a freight train, but like a SOHC 750 should with the 4500 to redline surge intact.  Now that I have her running as she should again it's time to do the rest...

Off to a good start....

[Desert-SOHC]

After riding her for a year or so as a bagger its time to go back to stock, she's just to small to be a bagger.  Also now that I'm fully retired I don't need a beast of burden anymore.  So she will go back to stock for mostly around town running with occasional trips.

I will be stripping the fairing and bags off her soon........................

As she sits now...................
