Title: Fork Seal, to This? New member, Damn All of You.
Post by: Fry on April 22, 2008, 04:31:40 AM
I have a 1995 GS 500E with 6300+ miles on it thats been in storage for a couple of years. It used to be my Ex-Girlfriends bike however the bike remained long after she left. It's all stock except for the Carbs have been re-jetted along with a full Hindle Exhaust and Carbon Can along wuth a K+N Drop in filter.

With Gas prices the way they are, and not being able to afford the newest and greatest crotch rockets I decided to pull the bike out of storage.

Heres the Rub, the bike is the stock metalic Purple with White rims so in addition to detailing everything, I had planned on painting the Rims and Tank a Semi Flat Black along with removing the Chin and Headlight spoiler/bodywork.

I found GStwin.com looking for a "How To Article" on replacing a leaky fork seal, what a great resource, heck some of the members of the site even posted up pics and how to's that showed me the tool I needed to make to remove the damper rod, how cool is that. More on this in a seperate post. I made the tool, just havent tried it yet. The bottom allen bolt spins freely but won't come out of it's bore? Anyway think I just have to use the tool to get the inner portion out.


Anyway the site fortunatley or unfortunatley depending on how you look at it led me to  pictures of "cosmiccharlie" project GS, what a mind blowing bike. I plan on following his lead for most of the Mods.

What I'm really curious about is the Sub Frame/Seat Frame mod to fit the Ducati Monster seat. I have a Mig Welder, Chop Saw and all the needed tools and welding skills to complete the project however, I'd like to know if any of you have any detailed measurments of what to cut on the stock frame(Sub Frame Lugs) and measurments as to the new frame created?
Do you cut off the smaller rectangular bars and just repostion them? Or on the main frame do you cut the lugs off, that the seat frame bars weld to? If so do any of you have the measurments as to were you repositioned them to?
I suppose it would be easier to visualize what I need to make if I had the Ducati seat, I'm just hoping to get some insight beefore I take the cutting wheel to the frame/subframe.

Thank you for any info you can provide. I contacted cosmiccharlie and am waiting to hear from him.

P.S. any links to the "K+N Lunch Box Filters? With this proposed mod I'll be ditching the Stk. Airbox and repostioning the Battery Box so I need to get this so called "Lunch Box Filter" in addition to the Ducati Monster Seat(What year do I look for?)

P.S.S While searching the archieves someone mentioned DirtBike style bars wouldn't fit pre- '01 bikes? Whats the issue here, why won't a 7/8th's bar fit the 1995GS that I have?

P.S.S.S Really interested in the Plu and Play Swingarm swaps, so from what I gather early '90's Gixxer arms, wheels fit? Would I use my current shock or the GSXR one?, What about linkage if any? Bearings, Spacers? Shims? Also I gathered from reading, Katana forks fit right up as well? Are they really much better?

Anyway, Thanks to all that inspire and offer assistance, I'll keep updating the pics if any are interested.

Heres the bike pre-finding this site:

Heres the bike after viewing this site:

Heres where I'm at with the fork seal, need to finish disassembly.

Forget the cosmetic charlie's bike ... you need to check out Dgyver's bike  :bowdown:
Anyway. I'll sell you a whole Katana front end for $450 ready to bolt and run. Everythign you need, discs, brake system, clip on's headlight ears ... all the bits that are not GS500. PM for details.
Cool.

Same thing happened to me. I was able to resist for a year or so, but eventually I got sucked in and I've dropped more money than I want to think about in to my bike.

I would suggest at least doing something to the f/e, whether it's the kat swap or just stiffer springs, you really need to stiffen it up. Right now dgyver is working on my kat f/e and hopefully it will be on in the next few weeks, I can't wait.

check out the buell seat swap also.  I like those a lot better than the ducati seat.  Also check jim knopf's stuff if you think charlie has something.  Him, dgyver, and a few others are pieces of work to look up to  :cheers:

I'm well aware of this bikes short comings, heck when I ride it hard I swear I can feel the frame flexing, probably getting some feedback from the F/E as well however my initial plan for this bike was to make a plain, non PURPLE commuter bike to save gas and not be laughed at due to the color.

I have had Giixxers in the past (95 1100 and a 96 750) and have resisted the urge (Empty Wallet) to go out and get another Race rep. So here I am just planning on Spray Bombing the thing and fixing a leaking fork seal  moving all the way to stripping the bike to the frame, throwing a Ducati Monster seat on, cutting the frame and thinking about all the other possibilities shown here.

Argh.

Oh yeah, the K&N lunchbox.

Part number RU-2970

Here's a place to get one online

http://www.ajusa.com/details/index/2/KNF/0/0/0/0/KNF%20RU-2970 (http://www.ajusa.com/details/index/2/KNF/0/0/0/0/KNF%20RU-2970)

You'll probably want to rejet again after installing this.

Post by: Fry on April 22, 2008, 07:33:05 AM
Bucks, thank you so much for the link to the lunch box, ordering that now.

When I put the Hindle full exhaust on and slip in K+N I re-jetted, think I'll need to again with the Lunch Box fitting?

Thanks again guys, I appreciate the willingness to help. This forum is the bomb, when I was into 5.0 Stangs, Corral.com was invaluable. When I got into KTM's , ktmtalk.com was also invaluable, I've made good friends on both sites and learned a ton, hope to continue that trend with this forum.

Hey ... dont blame us, we just want you to have a safe bike so you kids dont get hurt  :cookoo: ... just safety modifications we are making mind you. Yea right safety ...
BTW that GS FE doesn't belong in a ball point pen.
Couple years ago, someone said they put it in a ball point pen and it bottomed out when they dotted their i's.  :laugh:.
Now here is another kicker ... you swap the rear shock and it will in 1 instant tell you how awful that FE is. Now if you swap the FE will you see how bad the rear shock is ??? and which is more important ??? I dunno, I swapped the rear 10 years ago and loved it, and am impressed with the kat FE so far but I have a GSXR shock on the rear ... but someone else can try a Kat FE with stock rear shock and post back here.

Yes K&N lunch box is a huge step up cos you're removing the airbox.  I'd go 150 mains and of course 40 pilots, 3 turns on mix screws and 1 washer under needle.
Cool.

Hi there,
Just a few thoughts...
You found this free bike (sort of) in your garage and you want to use it to SAV money and here you are talking about front end swaps, swing arm swaps, this swap and that swap?
Forget it all. :)
Just fix the fork seal and clean the carbs and ride the gas saving GS500.
What are you thinking man?
You're not looking for a racebike. You want a bike to save on gas. It will still be plenty of fun. And it works acceptably well as it is. You're not planning on riding the wheels off of it, I imagine, and I have the feeling it will suit all of your needs as it is.
Oh, and if you want to sell the chin fairing, I'd be interested if it's cheap enough.
Just replace the fork seal, go through everything, adjust away and ride it.
That's cheap transportation.

Best wishes,
Todd

To get the fork apart (I just went through this with one of my forks) clamp the upper tube.  Pull on the lower (Hell, I put my foot up on the table so I could use it to help with the pulling) and zap the bolt with an impact gun.  Pulling on the lower will put force on the damping rod, preventing it from spinning so freely.  A couple zaps with the impact gun should release the bolt.  Us as short a bit as you can to prevent torque loss along the bit's length.
Title: Re: Fork Seal, to This? New member, Damn All of You.
Post by: The Buddha on April 22, 2008, 08:39:46 AM
Kurlon ... well obviously no one ever told you to take off the bottom bolt or atleast loosen it with it still on the bike ... like take off wheel and loosen the bolt, the spring does the pulling for you.
Anyway if that dont work I guess we put in a vice and pull away etc etc.

And Fry - rear shock - also katana 89-98 I think, an easy and much cheaper swap than FE. $30-50 for 1 prolly. BTW that will really tell you how awful your FE is. Been there, done that, lived wiht it for 7- 8 years, had several others do it and say the same ... but I guess we all have to start somewhere. There is a few better shocks before stepping up to the remote reservoir range - sling shot GSXR, RF6/900, B12.
Anyway making mods is really going to add up ... and twrhouse is right, start upgrading stuff and its gonna cost you plenty.
Cool.

Post by: bucks1605 on April 22, 2008, 09:07:59 AM
That's true, but for under $100 you can completely upgrade your suspension, front and rear. Progressive springs up front and a kat 600 shock in the rear. I got my shock for $25 shipped, seems to be the common rate, although there was one recently on katriders.com that went for free. Progressive springs are around $60. I would look in to those two mods at the very least.
Title: Re: Fork Seal, to This? New member, Damn All of You.
Post by: Trwhouse on April 22, 2008, 09:22:02 AM
I agree with Bucks.
I'd at least do the Progressive fork springs, which I have on my GS500. I haven't yet installed the Katana rear shock I bought because I don't want to raise the back end of my bike (short legs, sigh...). I keep thinking I'll find a way to resolve that issue.
But new springs and fork oil are a WHOLE lot easier and cheaper than swapping front ends, which is NOT easy due to the steering stem issues, etc. It's a lot of work, and I'm sure it is better, but is it worth all of that to you for what you want this bike for?
I'd say no, and go with the Progressive springs and new oil, and a Katana rear shock if you want to.
Best of luck,
Todd

No, once you get the whole kit and kaboodle setup for a GS a Kat FE swap will be easier than a fork seal and spring job on a GS stock FE. I'd compare them as 1/4th the work for the FE.
I can swap the FE in 15-20 mins. A spring swap and seal job on a GS FE will be atleast 2 hours. Not including the time spent in these things getting soaked to be cleaned and assuming the platisc PVC pipe etc is all at hand. More stuff to get into place for the seal and spring job as well as more work. The Kat FE swap literally is just grease for the neck bearings. Also the kat 600 top plate is 1 piece instead of 2 piece like the GS so future removal is easier. The Kat also has a better fork design that you dont have to make that funky ass tool to take off the damping rod bolt.
A Buddha modded kat FE is on and off in 1/4th the time of a stock GS seal and spring job.
Cool.

When I swapped the Gix front end onto my old GS it only took about 45 minutes and I had no clue what I was doing, twas back in the days of noobhood.  Of course, the FE I bought had already been modded to fit the GS..........
Title: Re: Fork Seal, to This? New member, Damn All of You.
Post by: The Buddha on April 22, 2008, 10:33:43 AM
Right. Werase can convert them to the GS in 1 hour, when he did mine though last year I did a whole bunch of new stuff and it took longer.
My new set of instructions for my machinist also look like a 1 hour job to convert.
A swap from the stock into one that is converted though is literally 15 mins and much easier than fork seals on the stock one.
Literally the job of opening up the stock one and the springs and seals and what not and cleaniing them, installing seals and dust covers and replacing the springs and filling and measuring the oil and pumping it and measuring and putting the caps back on is all replaced by, removing the dash and moving it forward 1 inch, removing the headlight ear carrierss and swapping with the ones I modded, removing the handle bar and the fittings on it, removing the top triple plate bolt, then removing the top plates, the removing the bearing, the collar and removing bottomg triple. Then you fit the kat lower triple, put the bearing and collar back on. and put the kat top plate back on, then fit the dash on ... oh yea forgot, remove lock and swap that to kat triple. Anyway its simple and easier than installing fork seals.
Cool.
Buddha.

That was my first try, I had to resort to the vice and pulling after that and a few other methods failed me on that leg.  The other leg came apart and went together beautifully.  The problem leg fought me the whole way.  When it was apart I wire brushed the bolt, and couldn't find any bad threads, debris jamming the works, etc.  I used a small round wire brush to clean out the threads on the damping rod, and even after a few times threading the bolt in and out and cleaning up anything that came out, it was still always a very dry fit.  It was almost like the hole in the damping rod was undersized.

Oh ... OK that free spinning damping rod design is a special torture suzuki has reserved for beginner bikes ... which will more than likely be bought by broke young un's who also will be beginner mechanics. Lovely design feature dumbasses  :2guns:

Boys, boys, boys,
Yes, all of that makes sense.
But you are forgetting all the time and MONEY spent locating parts, finding a machinist, finding the associated Katana wheel, brake discs, master cylinder, brake calipers, brake lines, and all the myriad other expected and unexpected issues and parts he will then have to resolve.
Remember, this fellow started out telling us he wants to use this bike to save gas. He has it and wants to get it running.
At no point did I hear him tell us that he wants to invest a lot of money or turn it into a GS500-engined superbike. If that's what he wants, maybe he should just save his money and buy a used high-performance bike, but that's not what he told us. :) 
Yes, with a Kat front end and swingarm and various other parts it would be a much better GS500. But does it need all of that? No. It is fine for what he needs it most likely just as it is and he can do some minor mods and still have a cheap, reliable, fun and gas-saving bike.
It's all up to him of course, but I think you guys are going a bit overboard.
Best wishes,
Todd

Post by: Fry on April 22, 2008, 11:53:23 AM
Wow, two very distinct sides here. I go out to the garage to pull the motor and come back to 2 pages of replies, WOW.

The bike has been babied since new, within the 1st year the Chin Spoiler, Belly Fairing, Hindle Exhaust, Carb Re-Jet and K+N Filter were all added. Since then it has only racked up 6K+ miles. and has sat dormant for the last 2 years.

I've had Race Rep's and a few of my Old Riding Buddies have recently left the Dirt and gotten back into street bikes, one buying a 2004 R1, another with a stunted out GSXR600.

The pressure they leveled at me to get back onto the street has been tremendous yet I have been resisting the urge to buy something new, or slightly used. All that will lead to is Debt, Increased Insurance Points and Premiums and pains in my neck and back as the body has taken a pounding while off roading.

So combine the above with rising gas prices and I thought to myself, Hey I got a bike stuffed away, it's relatively quick around town is great on gas and only needs a fork seal and a color change for me to be seen on it. I know it will never keep up with most of the bikes out there(It wasn't suppose to when new) and I am not willing to spend much money making it faster, that's not where I am in my riding life right now but it can be a nice, creative bike. Seeing the current trends in custom building and some of the Mfct.'s using matte or flat colors I figured a blacked out tank and tail section would look good and not be much trouble to Rattle Can.

Yes, originally thats all I planned, re-spray and a leaky seal fix, then I found this site.

As mentioned in the original post I saw a project here that got my blood flowing, especially seeing the Duc seat fitted, the motor sparyaed in my color choice and the quality of work on that project. After seeing that my mind was made up that I was tearing the bike down to the frame and doing similar mods.

Buddha was nice enough to provide some info on the Fork Swap and a set up he sells but honestly right now it's only a marginal thought of mine.

My main priority right now is to fix the leaky seal (Everything is disassembled, cleaned, inspected and ready to go on that) make the sub frame mods to fit the Ducati Seat, Clean and spray the motor a semi flat black and detail it, strip the frame and swing arm and repaint them a dull aluminum as well as getting the rims stripped and painted something other than white. This is in addition to cleaning and refurbishing / repainting all the little incidentals and such, but basically at this point thats all I'm down for. That still is a tremendous amount of work but relatively cheap mostly my labor to clean, prep and paint everything. All I'm buying at this point is Ducati Seat, Fork Dust and Oil Seals, Fork Oil, K+N LunchBox, the required jets, Piant and Painting Prep materials. I have tons of metal lying around so what ever I need to fab up I should have the materials on hand for that.

In conclusion, thats it. I'm sure I'll have to buy more things  and do more fabbing than I have planned right now but I'm not going to try making a 2008 Haybusa out of a 1995 GS500E.

Thanks for all the advice, opinions and assurances, looks like I found a good site.

Yea that cosmetic charlie upgrade is the last thing I'd do ... and for your comparison I coated a GS frame on the inside - yes inside the frame section and powdercoated shiny black on the outside. Yea, I still sont do a drastic seat swap.
WHY ??? cos most seats look too fat for the GS. The R6 and the myriad of other seats are wide, as is a duc (monster right ??)... but atleast its not as bad as the R6. They all look great form the side, from the front or back they just look like Queen Latifah's ass on Paris Hilton.
Start spraying sheite ... and you'd find out double quick how shitty the paint you buy these days is. Really, factory paint is without a doubt better, as is their prep and the fact that they are working with clean metal.
Cool.
