The 426 came with a 14 standard, so things are a little different than you imagine. A 16 is a little tight, though, and sometimes the slider needs to be notched for it.

Oh, I guess I should know my facts a little better. I figured they ha a 13 just like everything else.

Yeah, the case has been ground down for it, but no chain guard and it is to high geared for trails, so 15 tooth has been ordered

I'd probably go back to the stock 14 if i was you...

I use a 13-51 with a heavy GYTR FW and Rekluse pro and love it.

I'm not a fan of gearing down a bike even for tight woods. Unless you are always riding in first gear I guess, but other than that it just never made sense to me.

Gearing down (and this is all in my own opinion) makes the bike to jumpy/jerky and overly sensitive to slight variations of throttle.

It also causes the need to shift more often since the effective range of each gear is reduced. These motors have a wide RPM range of useability...why take that away?

This advice is worth exactly what you paid for it by the way. :ride:

u can check out my bike in my garage, it works extremely well for me in the trails and is on the lower cost of mods.
Things that I would add to it would be for sure a flywheel weight, and the most important thing suspension valving for trails.

When you gear a bike down, it usually let's it lug better. This allows you to use the clutch less usually and results in less wheel spin. The less wheel spin, the more traction and the better the bike works in the woods.
