Which rear sprocket?
I've searched this one but not sure from what I read. Is the stock chain on the '06 long enough to fit a 42 tooth [+2] rear sprocket ? I'm leaving the stocker up front as I still do the high speed cruise thing. I'd go 1 maybe 2 teeth at most and where is the best place to order a new sprocket from?

I went 1 down in the front and up 3 in the rear and I had to buy a new chain

That adds up to +2= new chain. Thanks, cptcrunch

OK ... I have a ZX10r 06 and a CBR1000RR 06.
Smart Smart man !!!! I have had all of the super bikes and they are all geared plenty low enough.
I currently own a cbr1000rr 06 and a zx10r 06 and they are geared completely different. The CBR will run 5k on the tach while speed is 35 at most. However my zx10r along with the 06 GSXR1000 run 5K on the tach while speed is at 50 mph .... now that is a HUGE Difference.
Now back to the point .... when u go down 1 in the front you run the risk of laying the chain on the chain guard .... I know ... I did it and it sucked !! Now ... 1 down in the front is like 2.5 up in the back. However, that will cause the bike to buzz around and make you shift like a mad man. Further, it will make it hard to find the balance point when wheeling. Now ... if you just go up 1 on the back for the ZX10R or the new GSXR1000 that will only up your RPM around 500 .... which brings the Hit from 50MPH to around 45 MPH ... not bad.
I have swapped gearing out on R1's CBRs', and ZXs. I have owned them all and going anymore than 1 to 2 teeth up on the ZX10R will make it into a buzz saw. My current CBR1000RR 06 is 1 tooth from the factory of last year and it is a wheelie machine/ buzz saw.
Now there will be many many follow ons to say the opposite along with the Quick Kit (1 down in front) but try it for yourself. You can pick up a front sprocket for around $50 (1 tooth down) along with a rear sprocket for $75 (1 or 2 teeth up). You can swap them out and test out my input. You will find .... if you know how to ride and that's not a jab ......that 1 tooth up in the back with be the most you will want if any.
Give it a shot for yourself ..... you have to swap it out and give it at least 2 weeks to get use to the change. The guys in love with the 1 down front and 2 up back are the Stunt Only guys. Others stating these kinds of numbers just don't know any better and Im not trying to be mean. They typically read it or swap out the gearing before they ever get their skills up to make use to the stock gearing.
One last note .... given I also have a cbr1000rr 06, I spend time on the cbr1000rr site. And its very very sad to see so many young guys getting the same old bad advice to go one down in the front. That is completely foolish on the CBR do to its current low low gearing. I just sold a 02 R1, 04 GSXR750, 00 R1 and a 98 CBR900RR ( I buy/pile on some miles 10K then sell). None of them are geared as low as the new CBR but its the heard mentality at work. Now ... shared that because Gearing is the "Sacred Cow" for motorcycles so the heard mentality usual wins out over actual knowledge/experience.
Good luck

well with all that said I guess I really dont know much or have much experience, However it sounds to me like brobin01 likes to ride on one tire more than on two, and i know alittle about that I can ride wheelies as good as the next guy, but if I dont want to ride one then I just dont ride one, no matter what the gearing is on my bike. I have two 06zx10s and one 636 all three of them are down one in the front and up three in the back, and I dont know of any drag at all on any of my bikes. but i guess every bike is different, ( if you want to stunt ride then try going up 6 or 7 in the back, thats what the the stunt guys are running) I know a few of them and I dont think they would be happy with just two up and one down.

Thank You for your gracious response .... it was apreciated.
Can you do the forum a favor .... can you take either 06 ZX10R and run it at 50MPH and let us know what the tack is (In 1st gear of course). This is huge in the way of measuring the increase. See ... when you go down 1 in front (kind of like 2.5 in the rear) then up 3 in the back you end up with around 5.5 up. So .... that brings the Hit Down in the MPH but also Shortens the Duration of the Power Band. Meaning .... the bike will hit earlier (im betting 5K on the tach will be under 40 on the speedo) but the engine will spin up to quickly along with spinning to high before hitting the next gear so it Shortens the real power band duration.
I thank you ahead of time .... most of the folks treat gearing as a Sacred Cow so we typically (I own a small super bike buisness) get statements that are based on feeling or emotion insead of science.
One last note ..... you have 1 down in the front and 3 up in the back with No Drag. The reason you dont have any drag is because the 1 Down in the front Dropped your Chain a 1/4 inch ..... but you also have 3 up in the back which not Only Shortens your Chain needs but it also raised your chain back up over 3/8 of an inch. See ... your gearing is now up roughly 5.5 but given u went down one way and up the other you lucked out 
Thanks again,
Brian

Thanks for the feedback guys. I'm going to bolt on the +1 rear Vortex as soon as it gets here. That will shorten the wheelbase a hair and allow use of the stock chain.. The bike pulls way hard anyway with stock gearing - esp. after losing the extra throttle plates. I wanted just a little shorter gearing for easier wheelies and doing the tight mountain turns but no big sacrifice at 90-100. Have an '06 with no cats/single pipe/PC

That was a good choice based on our experience. You probably order an aluminum sprocket. If so you might get 4k miles out of it at most given the ZX10R torque. Make sure to watch the teeth ... If one goes the other tend to follow fairly quickly.
Let us know how it goes.... Im betting you will love the little moving the hit from 50 MPH down to 45 MPH .... that will still leave a pretty broad power duration.

Yeah I'm looking forward to it but only 4K max on the aluminum Vortex? Thats about as much as I expect to get from the PP going on the rear wheel at the same time. Doesnt seem worth the weight savings of aluminum or is it? I mean should I have gotten a harder material sprocket and prolong the chain life too?

If you know enough to maintain your chain and swap the chain and sprockets as a set, sprocket wear is not an issue. Aluminum will outlast the chain.

I'm here to learn. I take care of the chain but with only 3000 miles didnt want to replace it just try another gear ratio. My aim is to get 10K out of a chain and pair of sprockets - but I see your point about wearing a set in together.

hmm.... we typically see chains lasting around 10K at most even with good care. Now there are exceptions when it comes to 750 and 600's. Now the Sprockets are no more than a reflections of the Torque and Use. See ... the 1000's are torque monsters and when ridden hard with wheelies, stop light ball busting, and general on/off banging .... the sprockets will round off then one will tooth will break off and there goes the neighborhood. Given they are relatively inexpensive this should not be a concern. 10K on most bikes is roughly 2-3 season of use.
Regarding swapping out with Matched Pair. Yes, Yes and Yes again. We have more than once had to replace a single sprocket and/or chain with a kit. The More Mileage on the set the more synchronized wear is placed on the set. So ... if you have 7K on the set (1000 cc bike with hard use) and the Rear Sprocket is missing a tooth here and there and you try and just Swap out the Rear Sprocket, the New one will have a Good Chance vibration and/or excessive chain noise do to the improper match. However, if you have few miles on the set then you have a good chance of swapping out with no issues.
Of course we have the cases where a chain last 18K on a 900 along with aluminum sprockets lasting 10K on 1000. but those are far and few between.

Thanks much for the experienced observations. Great thing about this bike is you hardly have to kick it to get a mean rush!

I have 13.6k on my chain right now. I clean and lubricate my chain every 2 tank full. So far so good the chain still looks good to me. I hope I can brake 16k so I can time it and spend my money all at once including the valve adjust. lol

You need to learn what constitutes good maintenance. I can put 10k track miles on an aluminum sprocket and have trouble telling it from new.

Do you use an alignment tool?

For once I agree with Bovine, I use an aluminum sprocket from Sprocket Specialties, it was cheap and available when I needed it. My ZX10R has been primarily a track/race bike now ofor the better part of a year. The bike has almost 13k on it with atleast half of it on the track. I have just replaced the sprockets and chain. I replaced the sprockets because the chain was worn out, not because the sprockets were worn, and I wanted to try a new gearing. I Currently run -1 and +1. this gearing works great for getting the bike off the line, and for getting me out of first gear on our tight track. I tried -1 and +3 but it was just to deep of gearing, the bike felt like a 2 stoke all I did was shift it all the time....that didnt last but for 1 track day.
Typically I run the bike -1 for the street. but as the bike has become more a trackbike than a street bike, I added the 1 to the rear and love it. Gearing all has to do with what type of riding you are doing. if you do lots of highway, straightline riding...sport touring if you will, the stock gearing is fine. For curves and mountain riding I went down 1 in the front. For the track is hard to say, have to find what works the best for you.
I have dropped a tooth on my 03 ZX6RR, my 01 ZX6R, my 02 ZX12R(which had 20k on it when it got totalled, and 18k of it was on the stock rear sprocket and chain, with 180hp at the wheel.) and on my 04 ZX10R.....and none of them ever gave me issues with clearances.
I woudl recommend that if you think the stock gearing is too tall, to either add 2 teeth to the rear, or drop 1 in the front, you cant go wrong either way...

When in doubt, lean farther and go faster....

I use 2 gearing combos. California speedway gets 15-38 and willow gets 15-39. I use these gearing combos more for rear axle placement. Cal is smooth and technical, so I like a shorter wheelbase. While Willow is wide open and bumpy. I can use the long wheelbase at california but I have to raise the rear 4mm or else the front wants to tuck.
