go to z400central 13/41 is the combo to have. no you do not have to change chain legnth. the stock 03 gears are 14/40 and the chain is 96 links.

Thanks man, I was looking for the right combo, I was thinking 13/ 42, but thta migth be too much, 13/41 sounds abotu rigth.

how do you know what sprocket to run, without knowing what size tires he has. if your running stock tires . and stock gearing you should have 14 40 gearing wich gives you a 286 gear if you go to a 13 41 you will have 315 gear which is a drastic change unless your running 24 inch tires on the back. try 14 41 and you should be happy.

how would i gear a yfz 450 with 18s on the back with stock gearing? i want more low end. a lot more.

svtbolt04 · August 21, 2006, 11:31:36 AM

go down a tooth in the front

Fox17 · August 21, 2006, 11:41:19 AM

the stock chain will fit right? well i may just get new sprockets and chain. we'll see.

svtbolt04 · August 21, 2006, 11:45:30 AM

With one tooth, you dont need to worry about length.

Well I need more bottom end for the track, Never really topend for it.
I run 18's btw.
I had a 14 41 set up once on my z400, I didnt really like it, I felt VERY sluggish.

brokenbackt12 · August 21, 2006, 04:22:43 PM

If you are running 18s and your quad is sluggish with 14 41 gearing, then you need to check you motor and carb. My wife's bike is running that gearing with 20x11x9 Razr2 and it will spin them very easy. Here is a pic of her pulling the holeshot on her Z400 at one of the FTR Quad Scrambles last year.

rider skill has alot to do with also not just the bike.

klutchbuster400 · August 21, 2006, 09:54:24 PM

that was the time she ever raced. I have changed every sprocket size there is believe me there is something wrong with your zuki and buy the way she now runs 14 39 wiyh a 440 kit and it pulls even harder.

Oh crap my bad, I read that wrong, I thought you said she ran 14/ 39, which is my old set up haha. I mean tmy bike felt sluggish with the 39 rear, I would go 41 in the rear, but a front sprocket is much cheaper and Funds are low

tony pitts · August 21, 2006, 10:53:16 PM

I understand but changing the front sprocket 1 tooth is like changing 3 and a half teeth on the rear you will get lot of rev out of the bottom but less speed overall not to mention over reving your quad at top speed.I have done a lot of gear changing I have three quads yfz450 trail and mx, my sons trx 513 mx, and my wifes 440 zuki.
