Hey all....

Now that i got my bike running again decently(clutch kept slipping....), I am able to work on the things that i have been putting off. My first problem is the chain.

Tonight, i went to adjust my chain. I had the manual and it said for there to be between .8 and 1.2 inches of slack (up and down) in the bottom run. Well, okay, i test it, and it is good. I spin the wheel and it gets hard to turn. I test the slack on a different part of the chain, and i can barely move it up and down. There is alot of resistance in turning the tire. So i adjust the chain so there is slack at that point of about 1 inch, and i turn the wheel again, and it is still hard to turn, and now in the section i first tested, there is a LOT of slack now. there are several links are rusted, and it seems like a bunch are frozen, or semi-frozen. It has been like this since i got the bike two years ago, and it isn't as bad as it was, but i know i should have replaced it then, but i didn't.


To make a long story a little shorter, i want to replace my chain and sprockets. I am assuming that there are kits with chains and sprockets sold together? I want a good chain, like DID, adn good sprockets, probably vortec. I might go up a few teeth in the back, or down in the front, i dunno, but i wanna know what you guys are running (brand and size) on your bikes. I have a 96 750.

Thanks!

i believe on you rbike its stock running a 16 front and 44 rear..i would either go up 2 in the rear (my choice) or go down 1 in the front. go with sprocket specialists titan tough sprockets..they kick ass. i would replace both front and rear at the same time as the chain. did gold x ring is what i would use...stick to the 525 chain. 520 conversion chain wears quicker and is pointless unless u plan on racing and want to replace chains and sprockets once a month. hope that info helped. www.sprocketspecialties.com

your bike has a stock configuration of 16(fr) and 43(rear)....the gixxer (750's at least) didnt change to a 44 tooth rear till 1998.....

i recommend getting the RK 'quick acceleration kit' for your bike....its affordable, and performance minded as well.....it includes a forged steel vortex fornt sprocket (-1 from stock), and a aluminum vortex rear sprocket (-1 again....thats right....-1), both with the 520 profile, and RK racing chain (gold is extra) for about 150 dollars. Ive used it for six months now, and havent a problem one with it.

to check out your application.....make sure to remind whomever when you are ordering that you have the 1997 gixxer7½, with the 43 tooth rear....if your not sure if yoiurs is stock now, just count the teeth to get the truth...

good luck, and post up some pix already!!

yeah, that sounds good to me too. I have had no problems with a 520. Although, generally 525 and 530 equipment is mostly available most often. The deal with me right now is I'm running a 15 tooth front with DID x ring 520 chain and a Sprocket Specialists alum. 44 tooth rear. This has netted me some bottom to mid range speed. Although I'm not nearly as fast on the top. It also set my speedo higher by 4-5mph at speeds around 35 to 50'ish. When I go higher at above freeway speeds I'm looking at reading 8-11mph higher than what I'm actually going. I was fairly accurate up to like maybe 90mph when I still had my stock 16 tooth front. So you may encounter this problem if you go down one in the front. My thing is though.... stay with a 16 front and go up two in the rear, or maybe three if you wish. Either that or keep it 43 rear and only go -1 in the front. That is indeed about the equivalent of doing +3 in the rear by itself! I can attest to that.

Thanks everyone and keep the replys coming!!!


I think im gonna make a few phone calls today to see what i can find out, price wise, etc, etc and then figure out what im gonna get from where!

Its not real hard to change the sprockets adn chain, right? Ive never done this, but my buddy did his back sprocket on his 12r in no time, but how easy is it to get the front sprocket off?

Also, what does 520, 525 or 530 stand for? Is that the difference in the size of the chain, not number of links, but the actual size of the chain? (if that makes any sense)

Thanks again!


John

p.s. Pics will come when i get my VERY CRANKY computer working right and when it will let me download the pics from my dig cam!

Well to tell you the truth... I would go with this setup...

RK or DID, Gold X-Ring chain 520 (the number is how wide each link is)

Renthal Ultralite front sprocket (stock size)

AFAM rear sprocket +3 (so a 46 tooth)

You will like the punch and accel is great.

I'm on the extreme side. I have a Regina chain and afam sprockets. But I'm 2 down up front and 4 up in the rear. Great for powering out of the twisties and blast off from traffic. Dispite what you might think I can keep up on the highway but you do lose top end.

I had my chain and sprockets changed today (couldn't do it myself as I don't have a garage and didn't want my neighbours to see my hands covered in the stickiest shit on the planet
) Well I have gone down one in front to keep it simple. I cranked it up and whoa! I was touching red line in fourth at about 120mph. Does it mean that i was actually doing about 110mph at the time? It did sound diferent though. I had always wanted to ride this bike at high rpms for a long distance, so easy to keep the revs 'up there' now. I am just worried about the accuracy of the speedo. We have Gatsos everywhere here and police are hard on "rogue bikers". On my way back, this **** in a blue cage pulled out in front of me on Lambeth Bridge, These bastards are allowed to park up on the bridge and look at the Thames and the Big Ben for some unknown reason (maybe because of the weekend) He almost spoiled my day, good stoppie though

I just put Sprocket Specialists (15/43) with DID ERV520 Gold chain on Friday night.I did notice a little more punch in the lower gears-not much difference higher though.Just remember a little change goes a long way.Oh yeah,be prepared to clean out a lot of crap if you do it yourself and are anal.Like me

Your bike came stock with 16/43. I agree with this recommendation from earlier reply:

RK or DID, Gold X-Ring chain 520 (the number is how wide each link is)

Renthal Ultralite front sprocket (stock size)

AFAM rear sprocket +3 (so a 46 t)

Make sure you get a rivet type link and a chain rivet tool is a big help. Don't neglect your chain. You should never let it get rusty. Lube it after it get wet if possible. I always run way more slack than Suzuki recommends. I make sure there is a slight visible sag when the bike is on the stand, believe that is abot 1.5 " movement. I got this tip a few years ago at the track from the Professor: Dave Sadowski.

definitely do it yourself, its pretty easy. there are some posts on here explaining how to do it, use the search function. (you should get a manual anyway). I would go 1 down in front, or up 3 in the back. you might want to consider the 520 conversion, since you should change your sprockets and chain at the same time.

also, search "chain deals" under group purchases/member discounts, there is a guy selling chains and sprockets cheep.

oh yeah, its usually better to go up 3 in the rear, (1 down in the front=about 2.5 up in the rear) because the chain doesnt have to turn quite as tight a radius in the fron with the larger sprocket.

and you will definitely feel a difference.

Thanks for all the responses everyone


I am hopefully going to call around tomorrow and get some prices adn order the stuff! I haven't decided which way to go yet, one down in the front or up in the rear. I mean the stock gearing is fine for me, but i figure while i am in there replacing stuff, i might as upgrade a little!

Thanks again everyone and keep the ideas flowing!
