BCR's "Trixie Special"
« on: June 26, 2009, 02:39:47 AM »
Greetings to all! Thought i'd share one of our project bikes with you guys, "Trixie Special". We've been working on this bike for over 2 years now. Just been so busy lately with customer orders, product development and other project bikes that we haven't had anytime to finish this project. The bike started of as a 76 CB750F2 SOHC. All the mods on the frame are all done. We even got the frame powder coat in black last year, but recently decided to change the color to dark bronze. We already made the dual cap tank and single seat for it. Just need to bring it to the painter to get the Norton Manx stripes treatment and get the seat upholstered. We finished the engine rebuild last year, but a couple of weeks ago decided to open up the top end and  punched it out close to 850cc. Well now the engine is back on the frame, front end is in place and even mounted our 4 into 4 stainless exhaust to maybe push us to finish this project.

Here are more info bout the build: www.benjiescaferacer.com/trixiespecial.html

This is what what we did to the frame. Didnt really do any major mods to it. Just cleaned it up, and made a whole new tail for it.

     

And for some teaser pics, here's what the bike currently look like

   

Here are some of the do to list:

- Norton Manx stripes for the tank and seat
- get the seat upholstered
- mount the aluminum oil tank inside the gas tank
- find a nice spot for the oil cooler
- rebuild oil pump
- run copper lines for the oil tank and cooler
- run wires for the electrical
- make aluminum fenders
- run the lines for the brakes and hydraulic clutch
- mount swing arm and rear shocks,
- fabricate stainless rear sets and linkages
- reverse the brake master and use it as a clutch master
      ** i know it's easier to just get an after market clutch master, but i want that
          old CB look with the aluminum reservoir as if it came from Honda factory**
- install clutch
- offset the sprockets
- polish the calipers
- make a new housing for the tachometer


Hopefully before summer ends, this project will be all done.

Look'n blardy fantastic mate, whose writing the cheques to cover all of this? Don't answer if your boss or wife can see. :D
I think the thing I most like about motorcycling is the speed at which my brain must process information at to avoid the numb skulls who are eating pies, playing the ukulele, applying make-up etc in the comfort of their airconditioned armchairs as they make random attempts to kill me!!!!!!!

This is going to be very interesting to see finished! And curious to know how it handles with rear shocks moved and that excellent front end...but who cares really when you have that very very cool exhaust!!!

good luck!
Andy

yeah... it was those teaser pics that caused me to open up my wallet and order a set of those pipes. MAN they are cool. I can't wait to get my bike running to see if they sound just as cool (I'm sure they will.  ;D )

That's a bit self-contradictory :)

I'm trying to wrap my brain around how one would even make this work.  Sounds well-nigh impossible, at first thought, short of re-casting the whole thing fron scratch.  What are your plans?

Been waiting on you guys to finish that bike for a while now.  Fantastics looking pipes & I think you really hit the nail on the head with that frame color.  Subtle. Beautiful.
Yep, I'm the kid that figured out how to put things back together...eventually.

I like the frame mods. :) One question, though, about the rear shock relocation... With the shock mounted further forward and down, wouldn't it be extremely advantageous to add some gussets to the frame?

Seems like it wouldn't be all that tough, just cut up a few original M/C's and piece them back together in the right configuration, then weld, file, sand and polish.

It's the "in the right configuration" part that's tricky, not the raw materials.  I've been running it through in my head, assuming cutting and welding the only way short of re-casting, and I still can't come up with a sequence that results in a mirror image.  You'd almost have to cut the resevoir off of the cylinder bore, cut the lever mount tabs off of the cylinder, flip the cylinder over, possibly fabricate new lever mount tabs and weld them onto the cylinder, then weld the resevoir portion back onto the cylinder, drill new passages between the resevoir and the cylinder, and re-bore/hone the cylinder to clean it up.

Then file, sand and polish :)
