I need gearing and chain help!

[Justinhenry]

I have a 2002 mxz 600. I bought some 21/45 gears off ebay. I know my stock gears are 24/43. Not sure about chain length an splines, but these sprockets I got off ebay look to be 15 plate, 15 spline. The ones on the sled look to be 13 plate, 15 spline. Will this chaincase work with the 15 plate, 15 spline?

What do you mean (plate)?

Here is a gear and chain chart. I don’t think that a 15 wide chain will fit on my summit. But, I haven’t tried either.
From what I could find the top shaft is 15 spline by 25mm and the bottom is 17 spline by 27mm.
All of the after market companies that I could find only sell 13 wide parts for zx chassis.
Also, dootalk.com has a lot of information on it about these machines.

I ran 15 wide chains,15 wide top steel sprockets & 13 wide bottom aluminum sprockets on zx & rev chassis for years. Worked great.

Yep, same here.
OK, well, not the "alum" part, but a 13w on bottom anyhow.
I think that I flipped the 13 over the other way tho?

Yup. I just parted out two 2007 Summits, they came with 15 wide chains and top sprockets, 13 bottom. Pretty standard.
