I will add one other place the gs500 won't be much good. Across Siberia...the roads are bloody aweful and even modded the GS suspension ain't up to it. The word "roads" is used with a touch of sarcasm when refering to the aforementioned ...

This isn't a 10year old design it is a motor designed in the mid eighties. Now before you go jumping to conclusions, the mid eighties was towards the end of performance AIR cooled motors. Although this bike was never meant to be a supersports ( at the stage this bike actually came out, the NSR and RGV 250's made it look like a lump), It does have quite a solid performance/reliability profile for an aircooled 500. The cams are quite spritely, decent sized valves, 34mm "flat slide" CV carbs on a a 250cc fourstroke cyl. TYher IS stuff you can do to get more HP out of it but you are going to run into reliablity problems that will remove the MOST important point of this bike. I have seen just under 70HP gs500's that weighed less than 140kg, but you couldn't ride them on the street ( and certainly not for long).
Having said that two places where you can get more "performance" besides cleaning up the through flow. One is weight. The GS500 is full of heavy 80's designed stuff ( footpeg assemblies weigh kilograms) that can be lightened which is the basis of my project. The other is suspension. Almost every bike will increase it useable performance envelope by refining the shocks and forks especially the GS500. Decent suspension will allow you to ride faster AND safer. Won't help your straight line accelleration, but if yoiu want that, buy a megabike.
Despite the mega-cc-aphiles the gs500 will take you across any continent reasonable comfortably,  reliable, and with equal performance MINIMIUM to the vast majority of cars with the possible exception of Germany's Autobahns.

I thought for a half a minute about a chopped down GSX 1000 head...

And I thought a whole minute about microsquirt.

Then I thought much more seriously about a different bike with more power and FI and 70+ hp.

Then I decided the GS500 is really fast enough and it gets the job done.

Now I'm in a loop between different bike and GS500 is good enough.
General GS500 Discussion / Regular Forks [1990] vs Spanish forks [2007]
« Last post by J_Walker on March 21, 2018, 06:54:22 PM »
I have set out to find out the differences [besides one being a real PITA to get apart] along other things. Trying to put the 2007 tubes into the 1990 body, finding out there are some differences along trying to combine them. Mainly the piston being slightly different sizes [off by 1mm actually] the inner tubes has two different sets of plastic rings that make up the differences. I have been stumped trying to figure out how to remove these rings in a non-destructive manner. is the whole thing press fit in there? hidden threading I don't know about? it's just in there and the end of the fork tube is crimped over, no way of getting them out. the plastic ring has plenty of free play how ever and I tried pushing it out with a screw driver, isn't gonna work. now I'm trying to figure out what the purpose of this plastic ring is and whether or not it being slightly larger is gonna make a difference at all on how the forks are suppose to behave.

Not crying from sorrow - I think I was crying for the total emotion.
Or to put it in man terms - Crying cos that sports achievement was so beautiful ...

IMHO, slip on if you get one cheap enough and a rejet as spec-ed in the manual for non epa countries gets you the best bang for the $$$ without losing much in terms of longevity or much of anything else.
After 17 GS'es and countless hand made parts that have either ended in the trash pile or been used to a "meeeh" effect, I now have a bike with more suspension and cosmetic and tank coating etc etc mods than performance.
I have a 95 (weirdo me I like naked 89-00 style) with yosh Tri oval slip on (hey I am not above the cool sheite) with stock airbox and correct jetting (non epa spec as laid out in suzuki manual). Its a great bike to ride, reliable and will be till it wears the duck out (anticipated @ 40-50K miles)
It also has Bandit 400 rear wheel, Kat 600 suspencion RF600 shock, corbin seat etc etc.
For fun factor, improve the suspension and "correct" the jetting.
To waste $$$ chasing an elusive horse power number - yea do mods out the wazoo.
Seriously. lots of people think I conjured up a jetting formula out of thin air, with an OR sensor screwed to the exhaust and running down an empty highway @ full throttle.
OK OK I did that, but only for K&N and pipe.
The correct jetting is listed in the manual under "Canada".
For Sale / For Trade / Wanted / Hot Deals / 1991 GS500E - Chicago

Not mine, but found it on Craigslist around Chicago somewhere.  Looks nice so I wanted to put it out here in case anyone is in the area and looking for one.  Looks like it was posted 3/13.

I totally agree with all the above.  Hard to squeeze more horsepower out of a 10+ yo bike, though rejetting and air filter are simple enough.

As mr72 said, the cheapest and easiest way to change your exhaust note is to drill out the baffle.
My first bike was a Yamaha R3 and this is what I did (check halfway down)

Though to tweak the equation a bit, it's more about power to weight ratio.   I did a lot of changes to my bike, and think I may have shaved off 30lbs or so.   I don't have another stock GS500 to compare directly, but I do love how mine rides.  An extra 25hp and 20ftlb torque would make it the perfect bike...

To derail the conversation, I wonder how removing the fairings would help.  You would shave off a few pounds for low speed riding, but wonder at what speed aerodynamics would kick in and make the fairings worthwhile?
