77 750f cafe project, chop cut rebuild
« on: November 19, 2008, 02:50:18 pm »
So I finally got around to taking my '77 750f to my friends shop. Rode it there and generally I would consider my self to make intelligent moves. It was FREEZING!! on the ride over.
Once getting there and needing to thaw out for 15 minutes got to work on the bike.
Pulled the rear brakes, oem foot pegs, and peg holders (big ass metal pieces), marked up the front fender for cutting. Pulled the rear grab bar, turn signals, and seat. Cut the lower motor mount bolt and the swing arm bolt. Bike looks great so far and I am getting excited.
Next to do, mock up the rear sets, mount the cafe seat, finish off new front hand controls, send parts to the powder coater, paint the tank and seat, have the seat appolstered. and some minor touch ups.
Also need to tackle the wiring harness and remove all unecessary wires.
As for the color of the bike. Satin black with gold leafing design (not sure yet), powdercoat all chrome black and spray the wheels gold.



more pics to come

The shop is a friend of mine. They build anything and everything high performance. The tires belong to a high HP evo. The RR is the shop owners bike and the guy who is going to guide me through this project.
I will snap some other pics of the crazy ass things in that shop. Mostly vw and import cars with high HP.

As for th harness, I have it out of the bike and its time to unwrap, remove and put back together. Not running any accessories. Plan to use Kingofcustoms wiring diagram to guide me. Just plan to run a horn, on/off ignition, start button, headlight and tailight.
The goal is to get the bike and clean and minimal as possible.

FINALLY got the seat in the mail today after waiting over 2 months to get it.

So what is the best way to mount the seat to the frame with the intention of possible removing it from time to time. Also the seat pan to the base? I have read lots and lots of industrial velcro. True?

chopping the brackets was a dumb move this early in the game.

With any custom bike you build it twice (sometimes 3 times). the first time is a mockup, you get all your pieces on it and make sure everything works right, then you disassemble and prep for cosmetics. This is how the pros do it, amatures who do crappy work cut first and ask questions later.

Usually, when the bike is finished the first time, I mark everything I need to remove with red paint and then I disassmeble the bike and begin to cut.

and did you get the bike and all its systems working before you cut into it? if not it will make your life miserable on the back end.

Hello again Geeto.
The bike was working great before taking it apart.
As for the brackets that were chopped off. They belong to oil tank which I am not using and to the battery tray which I am not using. I looked carefully to see what I chopped off and ran through it several times before going nuts with the sawzall. And indeed if I cut too much, my buddy is a welder. I understand I am rookie with bike building. I have built and modified cars before. I know there not the same.

For the wiring harness now. I want to clean it up and remove as much wiring as possible. I plan to run only the following.
ON/OFF ignition switch
Starter button
Headlight and Tailight
Oil pressure light
Neutral Light
I am following the Kings Custom wiring diagram. Does anyone have actual pictures of the harness after modding? If so can you post a picture.

Again, I know I am a rookie. This is a learning experience for me. I appreciate your guidance and help.
I like things to have the bare minimum and still work as they are supposed to.

for the wiring harness, start fresh. Either keep the stock one intact and patch up any issues or start with new wires, solder, and crimps. Cutting the harness apart is just more work than needed and will make a mess, not exactly get you what you need.

Well got more accomplished today. Ground and sanded all of the brackets and their according welds off the bike today. Mounted the rearset brakets for the '04 gsxr rearsets. Fabbed up an oil tank that will be mounted directly under the pod filters. Measures about 10"L and 4"Diam. Made out of alum and will be using new -10 fittings.
Soon everything will come off and go out to the powdercoater. Will post pics soon.
Also shaved off the front turn signal arms off the headlight brackets.

Will be working on the harness while everything is getting painted.

The seat arrived and will be getting apolstered by a local guy with Diamond stitching pattern.

So everything is pretty stripped and ready to go off to the powdercoater. Any suggestions on pre prep before sending off to the powdercoater?

If you run into any wiring problems call me or email leasurem@purdue.edu You are getting a bunch of whining from people that don't have the intelligence or balls to do a project like yours, F'em, you are building a custom bike and it looks like you are doing a great job to me.  Building a bike 3 times?  Full custom frame, yes, cafe an old Honda, no.  Keep at it, Spring is only 2 months away.

len,  bought the mini supertrapp from ebay. I know summit and jegs carry it too. The muffler was $130 shipped to me. Just cut the flange off and had my friend weld it onto the oem header.

King, I have your wiring diagram. I must have looked at it 100 times. I bought the 30 amp fuse and a new ign switch (on, off, and start) similar to a car. No need for a start button. I started going throuh the harness and removing everything I think I dont need. I agree with not building the bike 3 to 4 times. If I dont like it now, I will wait till next off season to rebuild again. Thanks for all of the positive support!

here are a couple shots of the tank and seat. still not done. Added a red pinstripe so I will need yo update again. Also need to figure out how to clear the tank without disturbing the gold.
Paint is Satin black with a 14k gold stripe.



prep work for the tank to lay gold:

   Ya know I really like the gold stripe on the black.  Kinda has a John Player Special feel to it.  But after seeing your question about how to not disturb the leaf...that stuff is real delicate right?  How does it attach to the paint below?  I'm thinking the adhesive isn't real strong.  Good thinking out of the box, but I think good old fashioned paint might have been the way to go.
  But hey, I'm not a painter.

I am a painter and am intrigued by the gold leaf idea.  Please keep us posted.  You have a killer build going there.

The gold leaf attaches to metal or any surface at that with a adhesive called "size".
http://www.misterart.com/store/view/003/group_id/152/Rolco-Quick-Dry-Gilding-Size.htm

You have to sand down the applied area with 600 grit. They suggest to apply the gold over red paint or primer to really make the gold "pop". I said the hell with it and just went over the black. So with that said. I taped off the area that I wanted with painters tape. Sand with 600. Wiped surface down. Tack clothed it. applied the size with a brush. Light coats!!!! this stuff spreads out. Wait about an hour of so until it becomes tacky apply the gold, light brush on with a soft cloth, finger, cotton ball what have you. Let sit for a couple hours and then use a VERY VERY soft brush to remove excess gold leaf. Easier than I thought it was. Also grew up with my mom being a calligrapher, so I have seen it done a couple times.

I just added on a red pinstripe on both sides of the gold. I think it looks great! I will take pics today.

The suprising thing is that the whole job cost me about $125. Rattle cans and about 20-30 hours in time. Just need to figure out the whole clear coat thing and I am set.
