I'm thinking about going one tooth down in the front...I realize that can effect top speed, but (1) I don't race it, (2) the fastest I've ever got my 6R up to was 130 indicated.

So my question is...I know going one tooth down in the front can give my bike a little more tourque, but is it eventually wear my chain down unnessesarily fast?

What are ya'll thoughts on going 1 tooth down in the front...should I or shouldn't I?

Thanks!

I went one down in the front and the results were worth it, no significant chain wear to report.

Go green or go home...

Go down one in front, keep the old sprocket. If you don't like going -1T front, change the other back IF it's still good/straight/not too much wear.

I am -1T front, +1T back. I LOVE it. Super fast acceleration over stock plus my aluminum rear sprocket weighs a ton (okay around 4 lbs) less than the stock iron rear sprocket.

Be aware, if you do a lot of highway riding, it may irritate you -- it does for me when I do a lotta highway cruising between cities when I have to. It's like not having a 6th gear (RPMs high) Doh.

But yeah, more than a pipe, rejet, ignition advance etc, going down one in the front will make your acceleration stomp ass (vs stock). It's cheap too :D

Thanks bro, I was thinking of going up 1 or 2 in the rear, but if you say that your -1 in the front and +1 in the back and its like not having a 6th gear because the rpms are so high, I think I'll just stick with 1 down in front.

Thanks for all your input!

I went -1/+2. Believe me I can't even tell I've lost any top end but the acceleration is much better "read top speed post". Needed especially when the ol six just seems flat from getting used to it. Wasn't as dramatic as first thought. I put a new chain on when i re-geared put have noticed more binding at times when shifting. Checked for proper slack and such but it may take a bit of getting used to. Chain seems to make more noise around the front especially walking it out of the garage, don't remember stock doing that but it could be just the difference in the chain?

I just went down one in the front and the cahin seems to be making more noise. I don't know if it's just because I'm concentrating on the front of it. has anyone else had this problem?

na, i put my smaller front sprocket on about 10K ago, and my chain still looks brand new. however, if you're really crackin that throttle and bringin that front wheel up, then the chain will chatter from being stretched. my brother's GSXR600 has a 'flat spot' in it, where it's really loose, but then tight in other places. it could be that though; try putting the bike on a rear stand and feeling the slack in the chain.

mine looks and feels fine I have only rode it about 5 miles with the new sprocket. it's just when I put it on the rear stand and spin the wheel I can hear the chain but I think its just the plastic chain guard on the swing arm or the chain going around the front of the sprocket. At least I hope.

JoeyP, The old sprocket has rubber cushons to reduce noise and probably vibration to some extent. The chain rests on this cushon and makes less noise with the stock sprocket. Go see for yourself on the stock one. Aftermarket spkts don't have this usually. No need to worry though, less mass is better.

Marine, go for it. I went 1 down 2 up, and I love it! When it's time to replace the chain, I'll be gearing even lower.

Just swapped my front down 1 tooth, I noticed the noise too, but way easier throttle wheelies now, well worth it.

You'll love the change, marine! I'm one tooth down in front on my '97 and it make a tremendous difference :D

My chain makes a little more noise now, also guys. Like rdandy said, it's just because there isn't a rubber piece on the new sprocket - no big deal. I don't even notice it anymore.

tblumer,

I've got a red '97 with factory jet kit and one tooth down in front, but I have a jardine can.[:p] Tell me, did the ignition advancer make much of a difference for you?

I originally got the advancer because they recommended it in the documentation of the jet kit, but I could tell right after I installed it that the midrange gained a bit more snap to it. The advancer is supposed to help mid and top end. Between that and dropping a tooth in the front the bike is like a whole different animal, it lunges at the twist of the throttle.

I'm running about the same set up, Factory Pro 1.7 kit, Yoshimura can, Factory Pro +4 advancer. I did it all at the same time so I'm not sure which part did what. BTW, I am running a 15/39 set up and it will still power up in first.
