Finalized mounting of bobber mount to swingarm and rear bracket for the Bonneville chain guard.
Still need to trim rearmost end somehow that looks nice. :-\

Also began install of GSX-R carbs. Due to horizontal spacing issues, I need to fabricate some isolators.
Tried the 1-1-4-4 stock but that is not correct for these carbs.
So, I'm following the install I found on the cb1100 forum
http://www.cb1100f.net/modules.php?name=Forums&file=viewtopic&t=41909&highlight=gsxr+carbs

I'm going to finish the carb install before I rebuild them and paint the diaphragm tops a nice black.

That is it for now.

Nice

I'm going to have to do something similar with mine.

Got my custom velocity stacks from www.steeldragonperformance.com this morning.
Damn things are very nice and will look perfect on my GSX-R carb install.

This is what they call "semi-polished" and I think the finish is spot on to match the rest of my aluminum work on the bike.

Can't say enough about these. Really well made.

Been methodically working on my project, but not much to shoot pictures of until today.
Finished complete rebuild and refinish of Suzuki GSX-R BST34SS carbs.
This is a major upgrade for DOHC 750s. Lighter weight, faster response, ability to to run without an airbox.
Made new insulators, installed Steel Dragon velocity stacks, added crankcase breathers.

Next I begin building a completely new wiring harness.

wow. they look nice

FWIW, you can use the standard carb boots for this conversion, but you need 2x#1, and 2x#4 boots in the order 1-1-4-4.

I was about to try this, but I think I've got the wrong carbs? They look a little different to yours?

Ian, thanks for the reply.

These 86-89 BST34SS carbs would not work with the 1-1-4-4 boot trick... I tried them.
The later GSXR carbs have a different spacing than these (mine are equal spaced), maybe that is what you have.
I found this idea from an 1100 forum and it worked fine.

If you need some decent stock boots, I have some I bought on ebay that I can send you, PM me if you need them.
You can warm them in an oven to flex them some.

cheers,
brad

Great looking build keep up the good work!!

 

[Reinhard]

Agreed. Sweet ride and nice work.

 

[hedrives]

For the rectifier/regulator and the igniters I made a rubber isolated bracket that mounts under the seat.
The rectifer/regulator is spaced off the bracket, too, so there is a bit of airflow behind it.
Should be plenty of airflow around these components.

Now, the only thing in the tail will be the battery, new mini-fuse block and starter relay.

 

[hedrives]

Got this great small Lithium battery from Shorai.
210 cca should start this thing just fine.

So, I built a Bonneville legal battery tie down from scratch that mounts behind the rear seat.
This also has a bracket to rubber mount the starter relay.
It is bolted to the chassis plate and spaced off the bottom wit nylon spacers.

While I was sat it this weekend I made a mount for my GM coils.
I decided to mount the longitudinally leaving room for the wiring harness and carb/clutch cables on the left side.
The GM coils have a rubber insulator around the plugs, so I made a cutout in the steel to use them.
This will eliminate any possible shorts.

That's it for now.
More wiring harness work to come.

So clean....

 

[Slice]

Yeah, im with swagger on this one... thats looking really clean.

 

[RustyOlive]

those Velocity stacks are sexy!! i ordered some for my cb550 as well.. can't wait for them to arrive, I might stick my ______ in them, their so hot!! BAHAHAHAHA

Real nice bike you have there. You wouldn't happen to have another set of gsxr carbs laying around ? I'm looking to do the same set up. Keep up the good work!

thirsty1, thanks for the kind words.

No carbs, I stalked mine on ebay and they needed a total rebuild.
Just soak each one in carb cleaner.

Look for BST34SS carbs off an 87-88 GSXR 750 or 1100.
They will say "06B10" on the side of the body.

Got lots of rebuild parts from Dillon Brothers Motorsports http://www.powersportspro.com/pages/parts/viewbybrand/1/Suzuki.aspx

Here is how I built insulators for mine:

Here are all the specs for GSXR carbs in the THIRD message:

Also, thank you Rusty, Slice & Swagger. I really appreciate the input.

Really great build! The bike is coming together quite nicely. I wish i had half the amount of patience you do. Your attention to detail is insane. One thing i am going to "borrow" from your build though, is your very tasteful use of "steam punk" cooling/speed holes. Love all of the offset and different size holes. Keep up the good work and i look forward to coming back to your thread over and over.

P.S. Is there anyway to subscribe to threads so i dont have to keep finding the ones i like every time?

Man, thanks for the comments. They help me keep going.

Gotta be frank, much of my patience comes from budget issues.

If you do a full reply, not a quick reply, there is a subscription option at the bottom (or there was in the old format).

hey.. fyi..
A guy from another forum saw that I'm running stacks on my 550 as well. email me and in formed me that he was running the same ones as I. he proceed to tell me that stretching pantie hoes over the screens helped alot. and when their dirty or wet from the rain and wether.. throw out and stretch over a new one. quick and easy way to keep the crap out better.

just thought I would pass along.

cheers.

 

[hedrives]

RustyOlive, that is a good old racer's trick.
My stacks have screens in them already, though.
Don't want to stifle airflow too much.

 

[Slice]

Rusty - Thats a really interesting method...

Reminds me of when in rural south america surfing we used to take pantie hoes from the girls we met and use them to make coffe....
You take a wire to make a circle at the mouth of the stocking, then put grinds in the sock and run hot water through it, Really its a pretty good idea though!
Worked really nice when you have no coffee machines and are a 12 hour flight from the nearest Tim Hortons.

Point being - if it works for me to filter coffee should be good for the carb too...
