Are the carburetors on 01-02 gs500's different then previous years?   I though so.  And if they are will a jet kit for and earlier year work on the 01-02 model?

I was wondering because factory pro web sit list a different jet kit for 01-02 models but on eBay there are 2 jet kits that read different.

00 and previous years have smaller carbs than the 01+...

The '01 and newer carbs are different, and there aren't any jet kits available for them currently (at least one with needles).  Factory Pro lists a part number, but shows the kit as backordered, but the guy in their shop said it was never develped.

just spend 20 bucks and order the jets from your shop.  Do a search on 01 and jetting and your bound to find the sizes and types.

Talk to your Suzuki parts guy.  I had Suzuki  put in a jet kit on my 2002 and it runs great.  Don't go the cheap route.  Life is too short.  I think it cost about $85.  I had  them put it in.  No rough spots no loss in mileage.  Can run 500 rpm lower and fast warm up.

they are different and take different jets.
factroy Pro has developed a kit from what I heard and I thought someone here bought one. No needles though.

also, some info here:

Also, this was PM'd to me a while ago about the 01 jetting with pod filters and full exhaust:

2001 GS500K1-K3 stage 3 jetting

Okay I am finished, and not changing it anymore. I have tested many many times and this is the set-up that I get the smoothest and strongest pull with.

Pilot #20 bleed type
Small Main #67.5 round slotted
Large Main #147.5 round slotted
Uni pod filters
Vance & Hines Super Sport Exhaust
V&H timing advancer

I use the Dyno Jet needles from the 89-00 kit, but shimming the stock needle with #4 washers will work too. I'm guessing 2-3 washers will do it on the stock needles. The Dyno Jet needles are set at the third clip from the top with one #4 washer underneath. I went to the #20 pilot jet and found a little more power at the bottom end. Fuel screws are set at 3.5 turns out. I don't think I can get it any better than it is right now. A 150 main runs a little bit rich for my taste.

I think it's funny that you call it the "cheap route"... Suzuki is going to put the exact same parts in that you would order for the cheap route:   MIKUNI Jets.  Hell, when you order off factorypro, they give you the option of ordering MIKUNI JETS.  I recommend using MIKUNI jets because they are the standard for the bike and if you ever sell or need to play with the jetting you won't have to do any guess work.

So you spend 85 on the "jet kit" and another 120 on labor.  The bike runs smooth... you have learned nothing and spent alot of money doing it.  Then when you decide to rejet again because you add a pipe or change a filter or the temperature changes you have to take the bike back to Suzuki...

There is nothing black magic about rejetting- it takes a little time and little practice and for those that have the mechanical ability to do it themselves, should.  

I had all the same junk as Piper but found that mine ran faster with a 20 pilot, 65 mid, and 150 main.  No rough spots, no loss in milage and fast warm up.

So what's different about the "Cheap Route" versus the "Expensive Route?"  Besides the fact that I saved $150, learned how to take my bike apart, rebuild my carbs, and fine tune my jetting.

The 150 mains... oddly enough I think Piper's 147.5 is just about right for the warmer CA weather... When I did mine in winter in Canada... I had to use 150, but comming back to warmer weather the 150's seemed just a shade rich. I stayed with it, and lowered my floats a hair (they were a shade too high anyway) and it helped. Anyway... 147.5 to 150 is the warmer - colder weather. And the DIY jetting is honestly superior ... if for nothing else... the fact that you know your carbs now... you have problem you'll know exactly what it looked like when it was good, and what is different now...
Cool.

To each his own.  Even if you do your own labor get something that you know will work.  I rather have limited time to work on my bike.  In the past I did all my own repairs.  Now money is less important thatn time. About the black magic, tell that to the poor souls that seem to constantly be taking their carbs apart.

You're right- It's all about the time and money.  I seem to have more time than money- so I try to make my buck go as far as possible...

I might get some heat for this but- I think that most of the problems that people post about are their own doing.  Alot of people here jump in before learning how to swim.  They don't read up and they don't have the tools- and if they're not willing to learn or spend the time prepping, then they should take it to the dealer- that's why they're there.

OK Time??? The last I checked... The ride to the shop (~ 9 miles in my case - Lees Performance featured in Cycle world where they built a 250mph hayabusa is 3 miles,but they wont touch a 89 and definetely wont touch a GS or any of myother bikes ) and the return in the truck with wife and baby usually takes ~ 1 hour for 3 people )... aka 3 man hours. I can jet, do a valve adjustment, and oil and filter change all in under an hour. OK The first time I did it, just a rejet took a hour... but its still a drop in the bucket... compared to 3 man hours... BTW the Baby's hour doesn't come cheap... it takes the wife a good 1/2 hour to get it ready for a hour outside, and then another 1/2 hour coaxing him back in the house. If you dont have time... do it yourself. If the bike is broken and needs to be trucked out there... double the reason to do it yourself.
Cool.

the mechanic rate at my dealership is $60/hr. I make twice that and then some. If I do it myself it might take longer than an hour and I gain the $60. If I take it in I pay $60 and I can work, thereby still coming out ahead. Its a very individual thing.

Half your luck Pantablo,I make $16.25 an hour,usally only get about 30 odd hours a week,my dealer charges $55 an hour but as Im not very macinaclly minded I also took the easy option and sent  my 2002 GS to the Suzuki dealer,unfortunatly he stuffed it up,damaged the diaphram,so then I had to wait for a new diaphram but that never showed up in over a week and X-mass was approaching so was even more unlikly to show up so he fixed the diaphram best he could so atleast I could have my bike back,the jets still not installed as he said there was no point doing them till the diapram arrived.He also inffered that it's near impossible to get the needles out without breaking this part on the diaphram,which I take to mean "sure I broke it but you still have to pay for it "an argument Im yet to have :x  so in my case all the easy way accomplished was a week of being bikeless,a broken diaphram,no new jet's,a bike not running as well as when it went in and I'm pretty sure he intend's to bill me for all this  :?  I'm certain I could have done a better job of it myself ,couldnt have done much worse could I ?Sure wished I lived closer to seshdri srinath so he could make all my problems go away, $40,to $55 to rejet,hell I'd gladly pay you $200 to get the job done right,it's going to cost me more than that and I'm doughting this guy can even get it right,For an autherised Suzuki dealer he doesnt seem to be up on rejetting  :dunno:

WTF ... impossible to take out the needles wihtout breaking the diaphragm ... woweee I must be god himself then cos I remember taking out over 20 of these ... wait a min its 20 carbs so 40 of these ... dear lord my power is doubling right as I type this ... oh wait I also yanked it out of atleast 6 4 cyl carbs - my GSXR, the 4 eli's, the concourse, the 2 nighthawks ... make it 4 cos I yanked them twice ... wowee that's 40 and I did some more than just 1-2 times ... He's a moron ... and a lying cheat ...

I'd like to know what I got , then.  I have a Factory Pro jet kit for my '01, that says it's for an '01, that made my bike go heaps better, and it came with pilots, mains AND needles.  It has been in now for over 12 months.  Someone is not telling you the truth, and I don't believe it's me.

hmmm...i'll need a calculator for this...$60x2+then some = $150/hour...calculating...x40x52 = $312,000/year  :o

i just have one question...what are you doing with 600rr?!?! :? get a ducati 999r or something!  :roll:

Pilots ... or Mid's ... AFAIK ... no one sells pilots and in fact aussie bikes had the right pilots in it ... but that's the 89-00 ...

Nope, definitely pilots.  The stock ones in my bike were 17.5, the ones in the kit were 22.5.  There were no jets in the kit to replace the mid jets, so I'm still running stock on that.  I'm not even sure what those ones do.

OK then ... the aftermarket is coying me ...  :lol: ...
See mids and mains are also controlled by the needle ... you cut it to a different taper and its like you put in a larger main or mid I'd think ... pilots are not ... they are getting smarter by fitting larger pilots ... now did they have air jets also included ... did you swap those out ...
Cool.
