17 Tooth Front Sprocket Mod

[flyingbeagle71]

I finally have my 17 tooth front sprocket installed.  Initial observations:

1. Noticeably lower RPM's across the entire shift pattern
2. Acceleration about the same, didn't notice any difference
3. Not sure on gas mileage yet
4. Top end speed has increased, used to be 100 mph, now, 105 mph and I really haven't pushed it yet

I got my sprocket from Motorcycle Accessory Warehouse:
Part number: 44598
Price: $15.95
Description: JT Sprocket 520 Front 17 Teeth Mfg.#: JTF51217



Installation was pretty easy, I only ran into one issue.  The sprocket cover was glued closed from all the chain lube the previous owner used.  I don't think they ever cleaned the chain, just kept lubing it over and over again.  Once the cover was removed, I scraped tons of black nasty sticky stuff out.  Really gross.

For the record, I've got an '04 GS500F.

Did you need to buy a new chain or does your old one still fit? I am thinking about getting a bigger front sprocket.

dude this post is from 3 years ago. and no you shouldnt need a new chain for a 17 tooth. its only 1 tooth from stock

+1. Poor forum etiquette

I think you guys should cut the guy some slack!    he did exactly what we always tell people to do, and used the search.

and no, the stock chain will be just fine, as long as it is in good shape.

LOL I am going to find one from 4 years ago just for you dude!

[Toogoofy317]

Yama finds them from like EONS ago! LOL.

Guess we can like never be satisfied like you know post a new question and we like say "search" then someone like searches and post in like an old topic and people like say " Dude that's three years old"

It's like a Catch-22 you know!

Now I've got the blonde out of me yup it will fit just fine!

Well at least I answered him while bashing him... LOL

So do Ihave to get a front sprocket specially designed for a GS500F or is there a 17 tooth sprocket of another bike I can use?

[tt_four]

I don't know if anyone's ever looked into sprockets from other bikes, but in general I'd stick with a new one made for the GS. You don't know how used the one is you could find for another bike, and if you get one that's too worn it will just wear on your chain, and that will need replaced too, costing you way more than the $5-10 you saved on the sprocket, not to mention if it's half used, you'll only get half of the life out of it anyway.

On a side note. I thought the GS was geared pretty high, I'm surprised his top speed actually increased with a taller gearing. I wonder if the original poster was going from stock to the 17t, or if he had changed the rear in the past.

you could get a 17 tooth for a 95+ gs500e, I guarantee it will fit

About 2 weeks ago i commented on a GS Buggy post from like 2001 or something. haha

[galahs]

Im just wondering if any gixxer, sv, bandit etc front sprockets fit a 2005 gs500f


I tried my local dealer but they don't do 17 tooth front sprockets, and the places online I have found either don't wat to ship to Australia or want to charge $50 US dollars for shipping + the cost of the sprocket.

I did a search for JTF51217 and got

[gregvhen]

thanks for that.

[the mole]

Galahs, I got a 17 tooth for a GS from my local dealer (Mullumbimby) in a few days, love the gearing.

[BaltimoreGS]

thanks for that.

Please don't take this as being a jack ass cause I know it may come off this way but aren't you looking to mod for stunting?  You would want a smaller front sprocket (less teeth) to increase torque for wheelies.  Sorry if I missed the point of your post.

Do you know what brand sprocket it was?

[gsJack]

Sunstar 33317 sprocket also fits the GS500, costs a bit more than JT.

GS500/E/F sprockets all the same from 94 on.
