The Odessey of Wilma

Wil-Mac wouldn't fit on the insurance card...So she's named Wilma...officially! I have a good friend with a BIG truck and a race car trailer who kindly took me to Pa. to bring her home. Bought her from a nice gent (70) who didn't think he could use it anymore. traileride.jpg Test rides on his street made me think I lost my shifting touch. Got her home and registered and still couldn't find second from first...something must be amiss. Put about 45 miles on in two rides and knew that longer h-bars were in order. I could lean back against the seat, or grab the bars and steer, but not both. So a trip to my friendly neighborhood cycle shop produced some 18" apes and a well-used shorty riser for mock-up. This is where stuff started to get interesting

To get to the wiring I realized the body had to come off. I don't know what it weighs but a Harbor Freight block and tackle hung from the shop ceiling did the trick.IMG_3270small.jpgAfter a couple of hours of staring, poking, unwrapping tape, and following wires to their source, (remember its 39 years old and there is no wiring diagram) I found at least two separate wiring harnesses. Many wires changes color several times from end to end and some just ended...a piece of electrical tape sealing off the dead wire! Found four brand new relays that sort of lead to the signal lights but not functional anymore because of clipped leads. So after ripping out all the wires not in use, and adding wires for the idiot lights, I got all the control wires to the bars extended a foot each with proper soldered splices and bullet connectors for the removable parts. Only took three evenings work!

Somewhere in there I got to looking at the shifter setup and realized the bracket was broken and the were no spacers to account for the vw tunnel metal it used to be bolted to. A little fabrication and welding repair along with some washers allowed the reverse lockout to function properly ( no more reverse for second gear!) Almost forgot, the plactic bushing was toast so the linkage was real sloppy...made a new bushing out of plastic electrical conduit with my trusty little lathe. Maybe I won't be spending $40 for the cool bronze bushing on the internet, we'll see. Sorry, no pics of that right now.

Sorry for the long post, but its exciting to have some success. The bars worked out perfect, the wiring all works, well... almost, and I can shift with abandon without grinding any teeth.

When the new longer brake lines get here I can get it inspected and figure out which white-face tach and speedo to put on to replace the current speedo which swings wildly or sits dormant. No, I couldn't find the loose wire that must be somewhere in the rats nest.

And so begins the journey that will be filled with discovery. What to do, what NOT to do (not too much gas on launch!) and how far I can get in a day on three wheels. Wish me luck, this should be fun.
 
seeking gauges opinions.

I want to put a separate Tachometer and speedo on Wilma to facilitate shifting and law abiding. I would welcome your comments on good brands or styles. My one requirement for now is that they be white-faced so I can see the needle! I hate a red needle on a black face, takes too long to find it.
 
Thanks vwbug, I think my current speedo is a "speedway" which is driven off four magnets glued to the axle next to the tranny. Works intermittently, not sure of the quality of these units but I was tempted to buy another one due to the low cost and lack of history on this one.

on another note, I got the carb adjusted so she will idle, but cannot get her to run at less than 22 degrees initial advance with a timing light. Total advance is up around 56 degrees and it runs good and pulls strong as far as I want to take it. My research shows initial advance should be 7+ degrees at idle. Any suggestions or comments welcome.
 
Well, I got my new chrome triple clamp and bars mounted, moved speedo to the dash (temporarily) and opened up the sight lines a little. Still debating whether to cut the windshield down a little so I can see over it.

Got to thinking about my distributor advance and began to wonder if the inability to run well at 7+ degrees advance at 800 rpm is an indication of hop-up parts in the motor, the free flowing intake and exhaust, or just lack of skill on my part? As always, your comments, suggestions, and snide remarks are welcome.

Hi Kerry. I'm not a VW guy, but is it possible that your distributer got installed a tooth off? I had something similar happen to me a looong time ago.

About your windshield, it looks like a Harley. You might be able to find a shorter one somewhere and save the taller one for Winter riding.

Just my :twocents:

Nice Ride

Hey good thought BillR, But a little research shows a single offset tooth on the distributor drive...you can put it in wrong (off by one cylinder in the firing order) but I don't thinkl it would run at all then. On the matter of the windshield, You're right I should experiment with something else and save that one for greater need. With my full face helmet, I don't need a windshield at all, but with a windshield, I don't need a face shield!

Well, I'm off to the workshop to see if I can figure out microswitches to provide gear indicator lighting on the dash.

Yes, they told me that too. I consider myself lucky, I found a vintage vw guru to coach me.

Just for grins when you get your vacuum and timing issues sorted out, put a vacuum gauge on your engine

With good steady vacuum you can be safe in knowing your valve train is not broken;)

Back in the old days we set timing with a vacuum gauge when a timing light was not available

Looking for 16-18 in of steady vacuum and NO run on when shutting down

Thanks jack, thats news to me. Any idea where I could read about that relationship between timing and vacuum
 
Kerry read here, but there are a lot of variables to deal with including camshaft, compression ratio, carbon deposits and leaky gaskets rings and worn valve train

Poor castings, doomed pistons, burned valves the list goes on

Including vacuum advance units leaking, poor centrifugal advance weights

To name a few

Think of the engine as a giant air pump, air in air out

good article...several times, swapping around timing covers and vibration dampers we ended up with no timing marks or marks that were misslocated. I read somewhere, yrs ago, how to set ign timing with no timing marks available......at idle, advance distributor untill max steady vacuum is reached, then retard timing to take 1 in. of vacuum of the gage. I believe the vacuum advance diaphram was disconnected during the procedure. Over the yrs I have found many old vacuum advance diaphrams to be leaky, so always test with a vacuum pump tool!

;) Larry, I still believe in Old School ways like in your post

I would add a healthy test ride and pull the plugs and read them

I know a lot of folks are gona say you cant read plugs with this crappy gas, Yeah you can, it is a bit tricky but can be done;) If you pay attention you can see the timing on the plug

Thanks Jack, this furthers my knowledge quite a bit. I'm looking forward to my parts arriving and this engine running properly again. Just wish it didn't take 5 days to get something. I'm even buying spares I don't need yet, just in case because I hate "downtime "
 
Well, 500 miles later and I'm putting a new end on my "new" accelerator cable! Made the cable from tandem bicycle brake cable. Cable frayed and broke about 1/8" from the grip tube, guess I need a stronger/more flexible cable. Will look into that.

Found a tach/speedo combo on amazon for $35.00. https://www.amazon.com/Motorcycle-12000RPM-Speedometer-Tachometer-Cylinders/dp/B01LZKPEDL

Had to use the magnets and pick up from the old speedo cause the new one was faulty! Gotta love the new tech, umpteen different funtions and the pickup coil is faulty!

Made a trailer hitch to replace the wheelie bars, so I'm having a counterweight fabricated ( steel plate) to try holding the front down. Wish me luck, pics to follow...
 
Hey, nice ride. I got myself a gps speedometer white face on eBay for just little over 50 bucks. Works great and even had an odometer and has a red backlight on it.
 
For cables I have liked the Venhill cables and kits.

Real motorcycle sized cables in lined sleeves and an assortment of ends.

Very nice. UK based, but are on ebay.

You know...... I have been looking at sports watches like the fit bit thing. The ones for bicycling has MPH and distance traveled.

So.....speedo on your wrist.

But do they go up high enough in mph for you and your trike Rex ? If for the wrist they may have a speed limit they go to, and after that you are in the dark about your true speed.

Great idea if they have a range that goes up to plus miles per hour.
 
Wow!, that's what the trike feels like on some roads!

Thanks for the venhill link. I will get some parts from them. My minimum cable length is 118"
 
OK...here's the pics I promised. made the trailer hitch to fit the wheelie bar brackets, wiring the speedo was an exercise in perseverance, and the only problem with my trailer setup is I can't see the trailer in my mirrors unless I wiggle the handlebars!

It's brake time!

I had an eye-opening experience... make that scphincter-puckering...on the expressway with my trailer in tow. At 65 mph I was leaving extra room in front for safety, but when traffic came to a halt I was literally standing on the brake pedal wondering if I'd make it! Good thing I had extra room, I needed all of it!

so.......Wilma is getting disc brakes in the rear. I have a few questions to answer and the opinions of others would be valuable to help me answer them.

I see many suppliers of disc brake kits, ls one better than others for some reason?

Is a hydraulic line-loc a suitable replacement for a cable parking brake? I miss having a parking brake, so I need to add something.

Thanks in advance?
