Starting to make some progress on my GSXR project. Little back ground on the bike. This was once a local drag bike. It changed hands a number of times over the years and turned into the A typical ghetto cruiser. Lots of chrome and rigged engineering. When I took possesion of it the bike was in pretty dier shape. The head was removed, cams and cam caps missing and pistons rusted to the cylinders. The wiring has been hacked and tied back together, bolts rusted and galled in place, chrome chipped and polish oxidised. Basicly a propper mess. Once I got into things I found a neat suprise. The engine has been taken to out to 907cc. This being a 91 750M model I got one of the better motors to work with. The original head was worthless without the cam towers so I sourced a big valve head from the 90 750L. I managed to save the pistons and rehoned the cylinders. I'll have new cams by the weekend and the rebuild can begin.

The starting point:

Starting the tear down

Pile of parts

Motor out and rear end being removed. Also, the lovley rats nest of wiring.

the lovley one off lowering links, haha

Swingarm out and down to bare bones

The swingarm is being replaced with one from an '05 R1. Personaly, I thought it would just look right with the shape of the frame. Also it's got a little length to it over the newer GSXR swingers. So not only will it add a little wheel base to it, but it wont look like the rear wheel is stuffed against the frame.

New swinger

The R1 arm is a lot wider then the GSXR frame. Ended up having to narrow it by almost 1.5 inches. The rear wheel is from a SRAD. New spacers well need to be made along with a new caliper bracket.

The swingarm in place for mock up. Need to also make some spacers to position the dogbones and get new bearings throughout the rear end. The shock sits very close to the arm. I may need to notch the swingarm a bit to clear the spring.

But for now it's a roller

Enjoy the wiring yet?

that is, i think, one of THE largest subframes EVER!

 

[dogbreath]

Yeah dude it's as long as the frame, that's ridiculous, hah hah.

 

[endo]

I've always loved that swingarm...sexy...looks good on there!

 

[Scrapyard]

Yeah the subframe is huge. deffinatly gota wack that down.

BTW, just moving my post into the new section to help get it going.

 

[dogbreath]

Your personal domain at this point

:muah:

 

[Bad Habit]

Not just the subframe, but the tank looks long as hell, too. That's a fun project you got goin on there, fo sho!

 

[PsychoDad]

If I stretch I think i can touch that sub frame from here.

Cool project bike - Looking good.

 

[spyder]

post some pix of the machining you dod to the swinger if you can.. I gotta take almost that much out of the 04 R6 swingarm to get it to fit, aswell as 1/2" total out of the inside of my frame just to get chain alignment

 

[Scrapyard]

..., but the tank looks long as hell, too.

You're the second person to say that today. I may have to start looking into the fiberglass tank idea I've been thinking of.

All that machine equipment and you can't make a metal gas tank?

All that machine equipment and you can't make a metal gas tank?

What machine equipment? Man I work with hand tools, an old ass drill press, a sawsall and a crappy 110v mig welder. I'm still in the dark ages over here till I make some decent money to afford a machine. Besides, you ever picked up a glass tank compared to a steel one? You'll shave 5lbs with a full tank of gas.

 

[dogbreath]

Sounds like machine equipment to me!

Sounds like my garage...minus the welder! My dad just gave me his old Lincoln stick...I haven't used it since I was 15 or so...and I definatly don't have anywhere to hook up the 220 I need. I will have to wait until I get the new place, no sense in do that much work to a rental!

And nice gixxer...a friend of mine had one (last I heard, he still has it, but blew the motor years ago and never put it back together...shame...) that was bad ass. He had sent the motor off to yosh and could pass everything but a gas station! He always talked about the big bore kit, but never did it. He had also drilled holes in everything to make it lighter, and polished everything. You could comb your hair in the frame, but he wasn't afraid to ride it!

 

[Scrapyard]

That sounds pretty cool. I got an idea to do some old school styling with this one. Kinda like a retro cafe. Lots of polishing and maybe some flake. What all did your buddy have done at Yosh? You remember?

I dont think there is anything wrong with the tank.
You should get yourself a 11 Engine tho. Or at leats a ste of Cyl/pistons. Keep the 750 head. works great!

This guy Steve I know built a 7-11, 'bout a 90, 92 era. The thing's a monster ~ 160 rear wheel HP! Has to run twin oil coolers with fans, but it rocks! I'll see if I can get a pic or two.

Make it looks like a cube-tanked, clip-ons attached the the wheel, spoked wheel fucken OLD OLD OLD school cafe
