hello,
I searched through the forum, but couldnt find anything specific relating to using a new fron and rear sprocket. From what i read, using a 15T sprocket is better then the stock sproket. Now, tdan553527, you had said you got your sprocket JT sprockets. What i want to know using this has done for you. And my other question is what gains i would be getting form using a different rear sprocket for my 04 gs500f. Anyone could actually help me with this. Will these mods help my gs go up? let me know. Thanks
Hello, front sprocket change=quicker acceleration, have to shift a little sooner, lost some top end, easier to wheelie, revs about 200 rpms higher than before, with changing the front sprocket, no need to change the chain, if you change the rear sprocket then you will need to change the chain. 1 tooth down in the front=about 3 up in the rear.
Definitely worth it!
so are you telling me that if i change the front sprocket, i need to change the rear sprocket as well? or not. And changing the front sprocket will make it easier to do wheelies, but how about changing the rear, what gains do i get doing that.
THanks buddy.
You don't have to change both, 1 down in front or 3 up in the back should equal the same advantages.

hey,
do you know where i could get me a 15t fornt sprocket then? the interenet site of JT doesnt support online shopping. I live in Canada, so i dunno where i could get one. IF you could help me out i would appreciate it. Thanks.
See my GS500 Chains and Sprockets (http://www.bbburma.net/Documents/GS500_Chains&Sprockets.txt) listing. I couldn't say which (if any) of the vendors ship to Canada, but it's worth a look.
would it be possible to go to 14t sprocket? what gains would i get from doing that

thanks, your page is helpfull. I need your help. I would like to order this right away. I got a 2004 Gs500f. I was wondering if the 15t sprocket for the 2002 Suzuki GS500E. I figure that it might, since the bikes are practically all the same. Or if someone could help me out locating a 15t fron sprocket that would fit my model of bike, i would greatly appreciate it. Thanks so much guys.

it's not a bad idea to change both sprockets and the chain at the same time...sprockets aren't very expensive, and they are a wear item. I recently went to a 15 tooth front (kept the stock # of teeth on the rear), and I can definitely say the bike accelerates a little harder. not quite ready to take on the R1's and busas yet, but every little bit helps :mrgreen: the front sprocket is very easy to change, just remove the cover, use snap ring pliers to take the snap ring off, and slide the old one off and the new one on....
can you pop the bike up easier? and btw, what year/model bike you got.

I have a 13 on mine, big difference. I have a 49 tooth for the back but I can't put that on till I get a set of new lugs.

Yes. As far as I know, the front sprocket hasn't changed since the 1994 model year.
hey,
are you sure about that?! as i will be ordering from the states. Thanks alot.
I just went out to BikeBandit and checked for ya. (I checked Ron Ayers too because they display Suzuki part numbers, but their data is ambiguous through the years for this particular part.)
The BikeBandit part numbers for the front sprocket are as follows:
1989 490551-001
1993 490551-001
1994 490543-001
2002 490543-001[/list:u]I don't know of any sprocket changes between the 2002 and 2004 model years.
I think you're safe. :thumb:
alright,
the bike bandit website i found the rear and fornt sprockets for the 2002 gs500e. So, now all i need to know is what you recommend me getting(14,15,16). Do i need to change to a new chain if i buy a front sprocket? and do you recommend changing both? or just one. Let m eknow. thanks.
I'm not sure ifyou're asking ME in particular, but
tdan553527 pretty much covered it above:
16 tooth = Stock
15 tooth = quicker acceleration, more frequent shifting, higher RPMs in a given gear at a given speed
14 tooth = more of the same![/list:u]You can drop one or 2 teeth in the front without replacing your chain. All you need to do in the back is loosen the axle bolt (and the adjusters in the swingarm) and pull the wheel rearward to take up the extra slack. If your axle is already near the end of its adjustment on the swingarm then you MAY need to replace the chain after all.
If you're looking to create a wheelie monster then you might consider dropping to a 14-toother in the front AND adding teeth in the back. Like
tdan said, 3 extra teeth in the back gives you roughly the same results as dropping a single tooth in the front.
It all depends on what you want....
thanks, i appreciate your help, i just have one more question for you.
If i go with a 15t in the front, AND get a 45t rear sprocket, would i need a new chain? and what if i decide to ONLY get a 45t rear sprocket like this one here. http://www.bikebandit.com/partsbandit/product.asp?pf_id=2745513&dept_id=927541 could i keep the stock chain then? sorry for all these questions, but i dont know much about sprockets.
If you add 6 teeth in the rear you will definitely need a longer chain, probably one extra link for each extra tooth (although I'm not sure about the math on that). It might be worthwhile to get a length of chain with a couple MORE teeth than that just in case, and then Dremel / cut off what you don't need.
i decided ill just replace the front sprocket for now. My one LAST question is this. What do YOU recommend i do to my bike. Change the front sprocket to a 15t or a 14t since i dont need to replace the chain for either one. I want your opinion. Thanks again.
Sorry - I stepped out for a few hours. :roll:
You're asking ME? Hmmm, that may not give the desired result. I still have a 16-tooth front sprocket because I use my GS more as a commuter / tourer than a hotrod.
But I guess you didn't really ask what _I_ would do; rather, what I would do in your shoes. When "reading between the lines" in some of your earlier posts in the thread, it sounded like you wanted some wheelie capability. If that's the case (you haven't explicitly stated WHAT you're really after :dunno: ) then I would spring for both a 15-tooth and a 14-tooth front sprocket. At about $12 US each you could save on shipping by getting both at once and experiment to your heart's content without "breaking the bank".
The front sprocket is easy to swap out, and moving the rear wheel back and forth is pretty easy too. And if you eventually get tired of higher revs, or shifting more often, or just want to take a long weekend trip, you can always put the stock sprocket back in there and move the wheel back up.
If you simply can't afford more than one front sprocket, then I would suggest the 15-toother. Unless, that is, you want a more abrupt transformation from commuter to wheelie bike ... in that case go with the 14-toother.
I don't know - does this help at all? :?
lol, yes you are helping alot thx, i want my bike to be able to make wheelies easier, thats my main gain i would like to be able to do. My main point is if i need to replace my chain if i go with a 14t sprocket. Thats my main concern. And going with a 14t will give me better low end, but less high end right? i understand quite alot about sprockets now. This post will help a few ppl out if they search it. Thanks.
You're right on with the lower end / higher end. As for replacing the chain, let's use the following photo as a discussion aid:
(http://www.bbburma.net/MiscFotos/100_1433_ChainAdjuster_RightSide.jpg)
When this picture was taken my D.I.D. 520V O-ring replacement chain had about ... 12,000 miles or so on it. The rear tire is a roughly stock-sized 130/70-17 Bridgestone BT45.
When the chain was new, the axle bolt would have been a bit forward of where it is in the photo. After thousands of miles of wear it has been moved back a time or two.
The shaft of the axle itself is about as thick as the flat-to-flat distance on the hex-shaped part of the bolt head. (See this photo (http://www.bbburma.net/MiscFotos/100_1443_RearAxleWithHardware.jpg).) So if/when the axle is moved back until one of the flats on the hex-head coincides with the rear-most edge of the oval slot in the swingarm, there will be no more room for adjusting the chain.
OK so far?
Now, what would happen if you added a link to the chain? (Actually, you have to add both an "inner link" and an "outer link" at the same time.) My intuition tells me that the axle would need to move back by just less than one pin-to-pin distance in order to take up the slack.
(http://www.bbburma.net/MiscFotos/100_1719_ChainSwap_NewChainReadyForMasterLinkCLip.jpg)
Instead of adding links, what if you installed a front sprocket with one tooth less than before? The circumference of the front sprocket would be smaller by one pin-to-pin distance, and the chain would meet the sprocket at a slightly smaller angle. If I'm thinking clearly, that means you would need to move the rear axle back by a little more than 1/2 of a pin-to-pin distance ... right? (In effect, you gained one link and a little extra because of the smaller sprocket diameter. Divide the total gain approx. in half to get the distance that the axle must be moved.)
Are you dizzy yet? :? I am!
So, for a 15-tooth front sprocket to fit you should have a little more than 1/2 of a pin-to-pin distance left for chain adjustment before you start. For a 14-toother to work you would need a little more than a whole pin-to-pin distance.
There! With a little bit of measuring you can determine for yourself what to buy. Good Luck! :thumb:
LOL, wow, that was something what you just wrote. But like you had said before, i think i will purchase both the 14t and the 15t, and play around with the axle everytime i switch sprocket. Its not hard to do, just takes a while, and must be precise. So pretty much, i understand right? just must change the distance to the axle with whichever front sprocket i use. But overall, with the 14t and the 15t, i can keep the stock chain. Just must change the distance.
Correct-o-mundo! :thumb:
man, i love you. You helped me so much. thanks for your patience. And the site you gave me bikebandit.com, i love it. and i matched up the 1994-2002 year gs500e sprocket part to the 2004 gs500f part off jtsprockets.com and they match with the same part number. And i also figured it out with the help of bikebandit.com. SO you were right, it will work. You are the man.

I'm not interested in wheelies, so I didn't even consider the 14T. I tried the 15T and, yes it did accelerate harder but at the expense of more fuel. I currently have a 17T which provides plenty of acceleration for what I like to do (that is, stay in front of the cars) and is a much better prospect on the highway. As far as I am aware, there are no alternative rear sprockets for the GS. At least, I couldn't find one for my '01 here in Oz.
