front sprocket

So I'm putting a -1 sprocket on my 99' 7r this weekend. See how it goes. If I donít get the torque I want Iím going to put a +2 on the back. Anyone have any words of wisdom for me? Anything special I need to do to? I have the service manual and it look pretty straightforward.

Edit: - != +

Well, I assume you mean that your going -1 tooth on the front ?!? Your going to decrease your acceleration if you go +1 on the front and/or -2 on the back. I think you have it backwards if you're trying to get more oomph out of her. -1/+2 is a big jump though, so be prepared to be cruising down the freeway at close to redline!

Should be straight forward. To get mine off though, I had to break the drive chain. There wasn't enough room/slack in the chain to get the front sprocket off with the chain on it. Even with the rear wheel all the way forward! You may need to do the same thing if you still have the stock endless chain on it.

I had my '02 -1 and +2 for a while. I ended up putting the stock front back on to get better mileage and less RPM's at hiway speeds. You should have enough room to change the front without breaking the chain but you should probably change your chain when you change the sprocket anyway. You will like the extra power on the bottom end. Good luck!!

I thought of one more thing you might watch out for while doing this. When you remove the clutch slave cylinder from the sprocket cover, the cutch actuation pushrod is free to be removed. You shouldn't need to take it out, but if it does come out a little bit or is removed completely, it can go back into the housing cocked and then jam up your clutch lever. I've heard of a couple incidences of this.

It's no big deal as it won't hurt anyting, but its kinda crappy to do the job, put it all back together and have to tear it apart again to fix this. Just keep you eye on it as you disassemble everything.

I have -1 in the front and stock in the rear. It's should be enough torque for, it was for me.

I am running 15/47 on my 03 and love it. It does run about 8k rpm on highway at 80mph no big deal to me. It pulls like crazy and you will loose top speed. Mine tops out at about 140.

2003 zx7r, 520 conversion,+4 advancer, factory jet kit, hindle bolt on. GP shifting.

i'm running the 15/45, 520 conversion, and it is freaking awesome, i will never go back to stock, the difference in rpm's on the highway is not all that bad, but the difference in acceleration is awesome, this thing is so happy to pull up in third when power shifting!

to be old and wise, you must first be young and stupid
