Just a hello PICS!

[3imo]

Suzuki did that years ago. GSXR600. 

I agree with you, but I'm not in the market for a new bike.  Maybe you could organize a mass email protest to Suzuki. 

I would think Suzuki's thinkers will do away with the GS for good. Beginner sport bikes are loosing ground to cheaper 600's. from what I see anyway.
Look at the Gs500's direct competition.  Of course I may be wrong, I stopped reading sportbike magazines a couple years ago.

the GS has been around since 89' with essentially no changes. I wouldn't be surprised if they had a new design already thought up, if they are considering keeping a GS like bike around.

then again I don't know when to stop typing, I am sooooo bored and there arent many other thread I feel a need to reply too.  Oh well lemm see if I can find another.  Getting paid to sit around is boring work.

This it whats under the seat:

If your pretty handy with a welder and a bender you could do this with ease. I'm trying to keep the bike on a budget but i think it looks wicked good. Can't wait to finish.

My design is almost exactly that. I just picked up the frame I intend to cut up. (THanks Chuck)

I only have access to a press, not a bender. I was gonna take the piece to a shop to get pressed. But to the backburner it goes, I have a new V8 to install.   

does that tail come from a monster also?  You have any other tail plastics lying around the shop (cracked/broken) you could donate to a guy whose wife won't let him spend another dime until his truck gets running?

...
Does anybody have a running motor running larger than 555cc's?

Others have done it in the past. Enlarging the cases for bigger sleeves...then you will start breaking cranks. Lee (onefastgs) has a 627 (IIRC).

I am working on building a 650, but using a GR650 motor and a 4-valve GSXR head. No problem with the crank breaking, the GR's is a lot bigger. May keep the stock bore if my pistons fit properly. If not, then I will bore it to the max. Got bored with building the basic 500, 541, 555.

Nice work. Great to have access to a variety of parts.

Hahaha, don't i know it. I have a Volvo 850 turbo that i thought it would be a good idea to build a 400hp motor for. Well i thought it was a good idea. I'm not really "allowed" to start any projects until i can actually drive the volvo.

I have another monster seat (shorter people buy new bikes and buy the "low" seat for them and don't want the originals) but, i can't let it go just yet. The bike in the picture of the wheels could go any direction at this point of developement. I was thinking DESMOSEDICI but thats another story.

i think the difference between ours and cheaper 600s is the air-cooler vs water-cooled argument.  i like things simpler, hence i like my air-cooled bike.  yes, there are limitations, but it's easier to trouble shoot.

400HP! What do you plan to with it? Is it a T5 now?

Yeah, its a T5 with TD04-18t turbo, custom manifold, blue top injectors, 3" downpipe, venolia pistons, pauter rods blah blah blah. Money pit to say the least. Its all in and done now. The day i added coolant it started pooring out somewhere on the rear of the engine. i slammed to hood and havent looked at it in almost two months. I hate Cars!

[baco99]

sounds like a beast!

[T-Bone]

wow nice job.

[dubkeith]

So as i expected, i'm far too bust to put any time on the project for a bit. Whilst i await my swingarm, i put the bike together enough to ride. It's been nice enough this week that with the daylight savings this weekend we should be able to ride after work! Woohoo!
This is how she sits for now:


Sorry for the big pic, i don't know how to shrink it.

Hey, Dub, again I hope you don't mind. 
I took the liberty of using your pic to tweek my design, since yours is the only one to date to come close to what I am shooting for. 
I used the "paint" to change your pic to reflect my project Ideas.
I plan on moving the lower subframe junction point up.  here is what I came up with.

viewed side to side with yours you can see the difference.

I aim to use a different seat and tail, but don't know what just yet. Chances are I will use whatever I can get my hands on. I am shooting for something more along the lines of the pics I posted below.



My concern is the structural integrity of moving the lower subframe junction point up. My friends tend to think it will not support my weight. I think it will do just fine. It is steel after all.

Since you have first hand experience fabricating a new one-off subframe, I'd like your opinion on that, as well as anyone elses.

You guys are insane. that doesn't even look like a GS... wow.

Y'know i almost feel bad about changing the old girl too much. There is so much i respect about the simplicity and functionality of the gs, it seems a shame to ignore that. I'm just one of those people that thinks i can do it better my way. Heck, my wife is a 3D graphic designer but i choose to use "paint" to make my prototype pic of the GS.

If you look at my design, the subframe is different then how i ended up building it. The design was not strong enough for my 320 lb wife. Just kidding, it was probably strong enough for her (115 lb) but it flexxed enough to notice with (185 lb) me on it. That ruled out any chance of emergency two up or set of bags. The top portion is aluminum on mine while i used chromemoly on the lower section. Mainly because i am cheap and had the steel lying around and no aluminum. left. It works well, i might change it but for now i'm fine with it. Good luck with your project, anything i can do to help, let me know.

dubkeith, that is the exact look I am going for with the bike I just purchased!  Glad to see the monstor seat fit so well.  Now I am on the hunt for one!

[common sense]

When I saw those progress pics, all I could think was "this better not be an april fools joke"

that's one sick bike, how much to get mine done?

[baco99]

looks great!
