What is the stock front and rear sprocket on a 06 Z400? Also can I go down a tooth in the front and up a tooth in the rear and still use the stock chain? Or maybe down 2 in the front and up one in the rear? I want to get alittle lower gear ratio for more woods riding that stock. I don't want to change the chain if I can help it. It only has about 5 hours on it so far.

Thanks

I answered my own question with the search feature. I never thought of search for gearing. Anyway its 14/40 and from what I have seen if I go to a 13/40 should be just what I want.

You kinda answered your ? in the first post when you asked if you could use the same chain yes you can because if you eliminate one from the front and add one to the rear its the same difference.

 

you have this backwards, if you loose 1 in the rear its top end speed and if you gain 1 then its torque as long as you didnt change the front sprocket
the rear is more for fine tuning, when im running the dunes I go to a 13/39 or 13/40 depending on how much torque you want

 

I ordered a 13 for now, I am going to try that, then if I need lower I will get a 41 rear, if its to low I will get a 39. I think the stock chain should fit for either, might have to take a link out after it stretches some.

you should be happy with 1 tooth down(front).youm will still use stock chain ,no links out.

 

 

I have a 2004 Kawasaki KFX400 and I changed to a 12 tooth on the front and a 44 tooth on the rear. The original was 14 on the front and 40 on the rear. I really like this change since I ride both mountain roads and trails and sand dunes. In the dunes I use paddle tires. Oh Yea, I know most of you think I am nuts for going so low, but for me I love it. Sure I lost top end speed but I am not a speed nut. I want to be able to really gear down in 1st for rough trail riding.

I works perfect in the dunes since I mainly use 3rd, with very little 2nd, and some 4th. I essentially never use 1st in the dunes.

Oh, I did have to put a longer chain on, and space down my rear rock guard a small amount.

My wife is going to get a yellow LTZ 400 and I will put 12 on the front and 44 on the rear of it.

Where did you find a 12 tooth front at? All I could find is a 13,14 and 15.

I purchased the 12 tooth sprocket for Sidewinder sprockets, 630-513-1000. They are not cheap. I was about $65.00. The 44 tooth I got from a local dealer for under $25.00.

As I said, when my wife gets a LTZ 400, I will again do the 12/44.
