TECHNICAL MOTOBRICK WRENCHING In Remembrance of Inge K. => Project Custom Motobricks => Topic started by: Froader4life on September 28, 2013, 02:18:18 AM

So I decided I'm finally going to start a thread on my build. I have mixed feelings on build threads and I'm not sure I'm motivated enough to continue adding stuff but here it goes.
Got it 5 months ago. Apparently it's from Japan where a US military guy had it. Once it was shipped here at some point it was parked for no apparent reason. It had been not running for 11 years when I got it. The odo has 27,000 km on it. It was un molested and in decent shape for its age.
When I got it the only real issue I found was a hole in the tank from corrosion. I patched it but it's still seeping a little. I'm open to and fixes you guys know of. Anyways, I got it running after the usual fluid change and spline lube. I finally road it around the block (sitting on the battery and no front brakes). So now it's build time.
Now for some pictures. What I started with, an example of the direction I'm going, and a rough mock up.
-
I just started the fab and here's what I have so far. I made this new tail hoop section and cut off the passenger foot pegs and exhaust mounts from the foot pegs. I also have an example of how the new tail hoop is going to be angled. I just did a couple pie cuts on the stock frame.
-
Now for some questions. Anyone know any replacement foot pegs? It seems like there would an easy swap for the anvil style stock pegs. Also, anyone know where this intake tube came from?

Sweet!
I'd love to build a prerunner like that. I drool over the TC and JD long travel parts for my 86 Runner. Unfortunately about worthless in GA. :(
What the other truck in the first pic a FSB? The little bit of cage I can see looks pretty slick. You build it?
PBB= Pirate4x4 bulletin board
-
I actually use to work at JD Fabrication. The other truck is my buddies bronco we built together.
I only go on pirate 4x4 when I need something from the Toyota library.
-
So I was able to work on my bike today and order some new parts. Taillight and muffler are on their way. I got the new rear hoop mounted today. Also below is how I hid my ecu.
-
You cut the shock mount? I see this ending badly, even if the welds are good. Too many variables. :falldown:
-

Of course I cut the shock mount off. I showed other things that I built, I think I should be able to handle this. Too many variables? Are you kidding me bro? :hehehe
-
Are you moving the location of the top shock mount?
By design, the two shock mounts and the swing arm pivot point probably form an equilateral triangle.
If you move the top shock mount forward you'll be stressing things. I bet the mounting screw on the rear drive breaks off after a few good bumps in the road. Or maybe the shock will fail.

I have heard of the shock stud failing on a stock bike. Watch out if you change the geometry.
-
Thanks guys for the shock input. It is going back in the same place and the only real think I'm worried about is the lower stud. I'm sure it will be fine though.
As far as the budget so far I'm in it less than $500. That includes the cost of the bike, getting it running and all parts purchased so far. The big plan is to get it completely rideable and functional and reliable, and then when I save up a little, strip it down and paint/powder coat everything. But it's going to look like a rat bike for a while first.
Next on the to do list is mount the battery, upper shock mount, and then start working on the seat/cowl. I have a pretty good idea I'm excited about for the handlebars instead of clip ons. I should be getting to that in a couple weeks or so.
-
I would mount that shock with a u bolt... that way you could slide it around on the frame rail to dial it in...

Pegs. Some ideas for you off this Wulf.

-
Thanks grim. Those look good. I will look into buying a set if I can track one down. Just looking for a possible alternative to $350 rear sets.
-
You will probably have better luck getting K1 Pegs that are in a similar position. I more wanted you to look at that to see how they made it because chances are if you want to move the pegs back you are going to have to modify a rear set for another bike.
Some good shots of a K1 in this thread. They put the linkage under the peg.

-
So here's a quick update. I got to spend a little time working on it today. I was excited to see how the new taillight looked on the new tail hoop. Fits perfect. It's an smoked led unit with integrated turn signals and plate light. I also got my stainless glass pack muffler. It's going to look and sound sweet. I will probably be working on it some more tomorrow, possibly making new set of handlebars.
-
What I did today.
-
So not sure if anyone here cares but I thought I would try doing another update. I have been steadily making progress on my bike. The rear cowl is very rough right now. Not exactly how I wanted but it was the best I could do with the Harley tank I started with. Also pictured is my handlebar flip.
-
Nice solution with the handlebars, interested in seeing what you come up with for instruments.
-
Looking very good so far! :2thumbup:
-
Here is another little taste. I have put about 4 miles on it so far. Still need to make a seat and the exhaust and I'm going to swap the kick stand to the other side of the bike so I don't leave a cloud of smoke every time I start it. Just needs a little bondo, paint and powder coat and she'll be good to go...except for the hundred other little things I want to do to it.
-
Keep going, always interested in bike mods.
Just wondering, I guess your state does not require DOT lights? That rear light does not look DOT approved. My state does require it which restricts my choices on my project bike quite a bit. Wish I had the welding talents you have, I am still trying to find someone to weld up my shortened tail section.
-
Nice build man!
-
Nice build so far!
-
So I'm super happy with what I have just done. Two major things that I have wanted to do for a really long time. Build my own exhaust and swap over the side stand.

So I'm sure you are correct about my tail light. Is some china light and I don't really like it because it's not very big or bright. I will probably end up throwing one of my stock buell tail lights that I know will fix both problems. I'm also going to move the license plate to the ecu box right behind the rear tire.
I wish you were closer to me so I could weld that tail up for you. I love working on my k bike.
-
Nice build man!
Thank you. I just wish I knew how to rotate pictures.
-
I like it so far,especially the exhaust. That looks tuff! Take a peek at the moto instrumentation Dakota Digital has just for giggles. Al

I have checked them out and I think I want to stay away from too modern gauges. I have my heart set on speedhut gps gauges now.
-
Get somebody to take a vid of you passing by so we can hear that!
Looks cool like how it cleans up the rear.
-
So I'm still slowly making progress on my brick. Just finished my rearsets. I'm super happy with them! They still need to be finished and put the proper stainless button heads in place. Huge improvement visually over the stock ones I modified (last picture). I also remounted the plate. The cops might not like it but it's much cleaner. I'm still just doing the little nickel and dime stuff until I can drop some big coin and get it all set up with new suspension, gauges, custom seat, powder coat and paint. Oh ya, and the title would be nice too. Still trying to get it registered so I can cruise it on the street.
-
Nice job on those rear sets.
-
Nice work!
Any chance to get a weight on it at some point. Curious to see just how much weight you jettisoned.
-
462 pounds as pictured with maybe a half tank of fuel. Just weighed it today. I didn't weigh it when I first got it but I'm sure I have lost close to 80 pounds maybe. It's got a perfect 50/50 distribution though.
-
RS is listed as 548 with a full tank. A straight 100 is 527 so it's shed a good bit.
So now it's 5.1 lb per horse. Verses 6.1 per horse. Should feel like a rocket.
Throw a k1200 on it for a 3.6/1 ratio!
-
our 96 k1100 rs rolls across the semi scales at 680 pounds with full fuel tank + full tankbag + full sidebags + full 22 liter...

I went and checked out those speed hut GPS gauges. What a neat idea and they'll look good. I'm even thinking about the CJ Jeep version for my other obsession. A 4bt powered Jeep that I have several sets of different sized tires. My only concern is I wonder if those same satellites can track your vehicle? I could be in trouble if thats the case. :mm
-
If I ran a Speedhut GPS Speedometer I'd be damned sure to clear the data on a regular basis.
Paranoid the gauge would possibly do double duty as 'exhibit A' in court... :dunno
-
i hope you gotts the 10k shift light... cause 8k is just wrong...
j o
-
Totally awesome build. I'm impressed and envious.
-
Still making progress. The budget thing went out the window. Sold my other bike so I had some extra cash to drop. More updates coming soon.
-
To get the sidestand on the right it looks to me as if you've just turned the mounting bracket round so it fold up forwards?
Personally, bad idea - bank it over on a nice fast right hand corner, hit a little bump, sidestand catches and you've suddenly got no rubber on the road.......
Jus' sayin' like.
Putting the stand on the right in itself isn't bad, just that particular execution of it.
Apart from that, quite liking it - especially the exhaust. Well done on that.
-
Nice work . Just spotted this one.
So much cobblers aired about shocks [ generally ]and their mounting points !!!!!!!!!!!!!!!!
I'd be more concerned that BMW use a THREADED top mount bolt for the bush to rotate on. What school of engineering did THAT designer [? ] come from.
Sometimes you just have to think [ design ] out of the box ..................... BMW Oilhead based trike we [ RAM ]designed and built.

I see that the 2 mounting holes in the sides of the tank were bugging you even more then they bug me... Lol
-
Yes! I can't stand when people leave those holes and get a nice paint job on their tank!
Also here are some more pictures after I put the first round of powder coated parts on. The tail section is getting body work done at the moment and I'm also mounting a custom gauge. I'm also trying to get a rear shock from beachcomber at the moment.
-
For me, the parting lines on the wheels bugged me more... Which is how this happened:

Two birds with one stone Froader ! ................... Here's a pic of the 1" lower RAM shocker - and MY solution to "not" leaving the hole ".
BTW - springs only available in Red or Black - apparantly I was the only one who wanted Yellow ! :dunno2:

Fun looking build man- only input I can offer is the gas tank leak. I used some alumna weld from harbor freight- as the gauge was too thin for my welding gear/experience. Worked great- just hear the area- lower seam I presume- with acetylene or some other canned heat then swipe the rod over the hot metal and presto- it wicks right into the pin holes and your set- oh yeah- sand the area down first to her the oxide off.
-
Alright so it turned into a pretty high budget project after all but I built it exactly how I wanted to. And now it's done...for the most part. I have put about 12 miles on it at this point and I'm very pleased. It's freaking loud but fun and awesome. Here she sits. It's probably going on eBay soon so let me know if you know anyone interested.
-
Jeez Froader, that's a nice looking bike!
Not a big fan of the Café Racer theme done to the K's, but yours is one of the best I've seen. :2thumbup:
blakey.
-
I like it a lot.
That exhaust must be freakin' loud!

Hi there and greetings from Germany!
Hey Froader, i've been looking for a while for K100-Cafe-Racers, cause I also bought one of the early Ks and started with a CR-project. And I have to say, that besides the one from V-Custom Cycles (see attachment or here http://www.retrowriteup.com/flying-brick/ (http://www.retrowriteup.com/flying-brick/)), yours is by far the best one in terms of elegance and cleanliness (is that a known english word???) that i stumbled over until now. I like the complete package, although I have to admit, that there are some details that would make it a bit ambitious to pass the TÜV (german technical inspection authority) acceptance over here, to say the least :-)
Usually the K-frame somehow is not CR-compatible with the different angles that the gas tank, frame and bench provide, once they are visible when you strip the bike. But somehow in your case there is something that distracts the eye from this fact. Maybe its the complete package, maybe it is the combination of colours, i am not quite sure. Whatever it is, it brings the K close to the best CR it might become (from my point of view). The view from above with the rounded heck is simply beautiful. The only thing I have to criticize is may be the engine block, that I would polish a bit more so that it stands out more in contrast to the dark colours. And one thing that I am missing here are the signal lights or have I simply overseen them???
And I have two more questions:
1) Can you provide me with details of your tachometer? What make is it and is the mount self made or can you buy it that way?
2) Why are you selling such a beauty after you invested so much work and money in it?
TIA and keep up the great work!

Hey everyone,
as Froader4Life is obviously busy, does someone else have a clue about make and model of the speedometer he used on his bike (as shown above)
TIA

I hope it is okay that I post a picture in your post regarding the above question.
The make is Speedhut and it is very nice!
Model is: GR4-DUALGPS-ST-03T

Thanks guys!

Really love this build, halfway through the thread i realized this is the same bike that i found at bikeexif when i was looking for inspiration on what to do with my K100.
Cool stuff!
-
Does anybody know where I can get a tail fender like that, or cowl
-
Bravo,
Spectacular in a field filled with mediocre.

You get it from your mind and build it with sheet metal like he did, Devil.
-
Wow. Beautfful build. Where did you hide the battery, overfill, and abs from beneath the seat? Very clean, minimal designs like these really accenuate the lines of the k series. Well done.
-
.....
-
26-27 inches with the typical cafe seat would require a lowering of around 3-4 inches which is pretty much what you have for rear wheel travel before the tire starts hitting stuff. Might be a bit tough to get that low.
