"Test Mule" '74 850 Monoshock build

Finally got the rear brake pedal sorted; it took cutting off the clevis tab from the botom side of the shifter shaft body and re-welding it about 90 degrees counter-clockwise to orient it for vertical motion, then fabricated a bracket to mount it to, painted it and installed it all. Works a treat!

Also just received the peashooters and installed them. The seat is almost done, so I'll get much better pix tomorrow with it installed.

Now THAT is more like it...

Here are the first decent shots of the substantially complete bike. It is now officially for sale...

Just a few details to sort out, and a few more bits to install (custom brake hoses, speedo cable, tail light, air filters). Also need to source
a front fender that looks "correct" for the overall look; at present I'm trying to find a TL1000 piece to see what it looks like on the bike.
The seat is installed loosely, it actually sits right down on the rear frame loop when it's snugged up.

Like I said in the last paragraph, the seat knobs need spacers where the shocks used to be; the brackets tighten down and the entire seat base sits solid on the frame. Go back a page or so of posts, take a look at the seat before it was upholstered, in the pix with the upswept pipes...
 
I just got the custom brake hose for the rear brake; local test ride after lunch, after I bleed the brakes.

I won't be able to get it on track for extreme testing 'till at least Willow Springs (if they even let me) at the end of the month, if it's not sold by then.

As it is, I am NOT selling it as a race bike; I will push it well beyond "typical" street riding conditions up in the Texas hill country, close to track conditions in many sections.

C'mon GrandPaul - that was Friday, stop holding out on us! How'd it go?
 
I got sidetracked by paying work!

Took a short test ride with no brakes, inconclusive although the engine is strong and suspension feels great at slow speeds.

Don't ya just hate it when that happens.

Well that's very promising anyway.
Hope the paying work winds up soon and you can get back to the more interesting stuff.


Errrr... that's not exactly right. I think you know what I'm trying to say...
 
I've got to finish a client's 75 Mark III monoshock project before April 19th when I head west to deliver it.

I've got the engine in the rolling chassis; just starting to terminate the installed wiring harness, and run the oil lines.

I hope to fire up the engine in the next week or so.

The '74 really needs to be de-bugged by that time, in case a buyer desires a similar delivery time frame west of I-35.
 
I never was able to get a satisfactorily firm rear brake pedal, so I scrapped the entire hybrid rear brake setup and installed a completely new UJM setup. It did require building a caliper bracket adapter which is obviously not "factory" in appearance, but it WORKS!

This master cylinder is virtually the same, but uses a remote reservoir-

Now that I have proper brakes, I took it out for a rip and found out it will loft the front wheel without too much effort. DEFINITELY has to do with the cam!

I'm not thrilled about the 19" fender on an 18" front end, but I had to have SOMETHING. Haven't been able to source a usable TL1000 fender, and pretty much the only NEGATIVE comments I've gotten on the "Blue" bike have been about the modern fender. So...

Got all of the electrical wiring done except the flasher unit for the turn signals, and the main horn wiring...

I just might ride it to our CMA meeting in about an hour; what the heck, we don't need no steenkin' license plate!

Now that you pointed out the front fender it's bugging the crap out of me.

Otherwise looks good!

It was being baptised. It's a "Born Again Bike", after all...

OK Paul, well if you're going to do that, doesn't it only count if it goes in totally submerged? :mrgreen:

So...

1. Just a connector?
2. What is this?
3. Podtronic
 
1. Sparx ignition box connector

2. Tympanium solid state regulator/rectifier module

The little relay is for the horn.
