GS1000 streetfighter idea w/ picture

[80GS1000]

Carbs and airbox - who needs 'em?

Gotta now get these items fitted:

Going to pods should be worth the price of admission if only because the airbox will never ever have to be removed again. Giant PITA for sure.

Tomorrow's garage session will be entitled- Introduction to Front Sprocket Area Sludge Cleaning, The Intersection and Effects of 27 Years of Road Grime and Chain Lube. :lol:

A bottle of Simple Green and putty knife are standing by.

Last but not least, check out the width difference between a 130 rim/tire (stock GS1000) and a 180 (stock GSXR 1000) rim/tire:

Carbs are being jetted by a long-time NHRA drag racer who's been building out racing GS engines since they were new. \\/

Any tips on front sprocket removal? The nut that holds on the front sprocket won't budge a mm. First attempts at getting it to move just turned the engine over. So, I put the chain back on the front sprocket, had my wife stand on the chain (about where the swingarm would normally be) to keep the sprocket from turning toward the engine, and leaned into the 18" ratchet as hard as possible. Wouldn't budge. Is an impact wrench in the cards?

 

[Mike_H]

is it reverse threaded? I have a shaft drive, so have never had to change a sprocket and I am just throwing a WAG out there

 

[first timer]

check the direction of threads, make sure the locking tab is is not folded over and locking the nut, hook the back tire and rear break and chain back up, have a friend/wife stand on the break and give it a try with the impact wrench, just go easy, don't get carried away with the impact wrench it should break loose sooner or later, you can also try adding a little heat to the nut to see if that helps.

Damn that thing looks great with that big back wheel and swingarm. Nicely done!

Yeah, man... your project is coming along nicely! Major kudos.
BTW, I love my pods. I can't imagine trying to jet and tune carbs with some kind of airbox on it.

Thanks guys. Although we're just getting started on what will probably be the hardest part of this whole project thus far - getting the monoshock mounts right.

YoshiJohnny did it right. Major respect for that.

They determine a bunch of important stuff, like rake/trail, ground clearance, chain clearance, ride height, sufficient travel for the rear tire, stability, overall safety etc etc. Gotta get it right. So ya gotta take it slow, take lots of measurements, engineer things carefully etc.

The upside of this complete suspension change will be a bike that handles vastly better than stock. Planted, very stable high speed/angle cornering. And much better braking. And a 180 Michelin hanging out back looks pretty cool too.

I'll bring the bike to the Yosemite GSR get-together.

Cool! I hope my project is done by then. It's been going s l o w the last few weeks.

Same here! Big incentive for me right now to get the suspension mods done is the fact that spring is rapidly approaching - I want to ride the thing! :-D

 

[jonesti]

Wow, your project is flying right along! Looking good. Sorry about the rear wheel. Same thing happened with my radial front master. "Perfect condition. Won't be disappointed!" Yeah, perfect minus the fact the reservior is rashed and the juntion for the line to the reservior is crushed.

Take pics of everything. Most of us on here are guys=VISUAL!!!!

It's a 2004 GSXR 1000 front end. You're right on the money in terms of the Spiegler handlebar/mount kit. Very nice CNC machining on that kit, and as a bonus, it came with braided steel brake lines for the front end.

The riding position is great - about the same as with the old bars as seen in the pic on page 1 of this thread.

That settles it then. I have a friend who deals Speigler stuff, and said he can gimme a solid discount. Speigler here I come! \\/

Getting burned sucks, doesn't it? Here's a pic of that "straight, no damage rim"
:shock: :^o

It's about as straight as Elton John. Huge flat spot in the lip.

Guy says he'll refund my money once it shows up back at his place. We'll see....I left a nastygram in the box with the rim when I shipped it back to him today....and filed a Paypal dispute.

 

[jonesti]

Holy sh/t! Perfectly straight....with the help of a 5lbs hammer and dolly!

 

[beergood]

It's been a while since I was last e-screwed. What sucks the most is that the guy doing the screwing is almost always on the other side of the country, so you can't show up at his door and smack him a good one.

It would be terrible if you accidentally packed a hornets nest with it when you sent it back. Or I could give you a couple of these little things my dogs make. They can be pretty unpleasant.

It's nice to dream, isn't it?

 

[80GS1000]

I set the pre-sag trail at a preliminary 3.75" with the floor jack and mocked up the GSXR monoshock. The rear shock and forks should sag about 1 to 1.5" with the weight of the bike and me on it, getting the total trail to about 3.9-4.0". To put this into perspective, a current spec GSXR 1000 has a trail of about 3.9". It'll steer a LOT quicker than the GS1000 stock geometry did, but still not be twitchy, and will be stable at high speed. It should feel more planted in the corners with the front tire weight bias and the wide radial tires. And there should be plenty of ground clearance for the exhaust and for cornering. Ground clearance at the lowest part of the front of the frame is sitting at a pre-sag figure of 10" in the front. Sitting on the bike with the seat on, I'm on my tip-toes to reach the ground, which is about the same as before. I may cut down the seat in front so I can reach the ground better, and to create more of a step in the seat to lean into when accelerating.

Anyways, enough tech/mechanical engineering stuff, onto the pics! \\/

Mocked up with that steering geometry (and a stand-in Katana 600 rim with 160 tire while we wait for a new GSXR 1000 rim to arrive):

Without bodywork:

With tank and seat:

Seat, tank, and side panel:

I'm kinda leaning now toward leaving the side panels off now. It just makes the bike look harder, and the Yoshimura GS1000 didn't have side panels anyway.

 

[beergood]

Day-um, for being one hell of a project, it is really turning out nice. Quite a feat of engineering.

I agree that you should lose the side panels. Once you lift a bike like that I think they ruin the line. I would either fab something that looks more in line with the new profile, or lose them entirely.

Lookin good.

Looking really nice - except for that mattress of a seat ya got there :lol: trim it down for sure!!! I'd make it stepped, with the top of the back part being level with the top of your tail.

Love seeing the progess - inspires me to try and find time to do more on mine - most of the time I can only find time to keep buying more stuff for it on E'sgay (just bought 36mm GSXR flatslides). Keep it up!

Great idea on the stepped seat with the back level to the tail- I'll have to Photoshop it and see how it looks. 36 mm GSXR rattlers? Nice!

 

[beergood]

You could chop your frame a little. You already lost the passenger pegs, so you probably don't need all that seat (or do you have plans for riders?). Just a thought, and you obviously have the skills to do it.

My girlfriend lamented that when I chopped mine she wouldn't be able to ride on the back (I never rode with her, so I don't know how serious she was). I countered with the offer to help find a bike of her own, or to teach her to ride the 500. I'm not going to hold my breathe on that one.

I love the aggressive stance these mods have given your bike.

 

[solo suzuki]

the angle may be close enough that you can photoshop/cut and paste this seat on for size! :?

great project by the way, been watching a couple on the site with interest...
