It's listed above. Snail adjuster on position 1.5.

On the street, I can take off in third with the low gearing.

 

It depends on the kind of riding you're doing. If I were doing lots of street riding, maybe some gravel roads, I'd either leave it stock or go 15T front. I do primarily tight single-track woods and have a 13T/47T combination that works very well. You'd probably burn up your clutch with a 15T/42T combination in most of this stuff:

 

Nice trail and great start! Watched a few minutes. Looks like there's places where you can even get into 2nd gear!

What's with your dash?

 

Just depends on your riding. I creep up and down steep, narrow, twisting, rocky trails going around and between trees and cacti. 90% of my riding time is in first or second gear. Wouldn't mind even lower gearing.

 

Looks like a mount for an LED array or something like that. I have one of those: "36 watt" (not really), 12 LEDs.

 

My dirt excursion was really tight trails. Imagine the trails in the video except not maintained so a bunch of ferns and face slappers all over. I'll admit that for the super tight-make your own trail that we have in the Pacific Northwest, the stock gearing was better as you could let the clutch out in first and not even have to worry about applying throttle. It just seems to me like folks are doing themselves a disservice by gearing so low. But the whole dual sport thing is about compromise, that is for sure.

 

I got the 13/49 sprockets installed, I think its going to be good on the trails, I'll hopefully find out next week. What did you guys do with the lower chain guard with the larger rear sprocket? The stock one wont work anymore.

 

With the 351 and the rest of the engine work i've done it will pull the stock 14/42 gearing but the problem I sometimes run into is that with that setup the rpm drop on upshifts when going up some of the terrain I encounter requires covering the clutch to make sure it would make it. I'm talking about slopes greater then 45 deg with some switchbacks thrown in for good measure.
I have ended up with a 14/45 combo(works out about the same as the 13/42) and it lets me grunt up hills with no problem and still lets me travel at 60mph when connecting trails over the road. If I stayed completely offroad I wouldn't hesitate to add 3 or 4 teeth on the rear. The other advantage of running steeper gearing offroad is that you have better control on downhill descents due to more engine braking.

 

I redid the 'number plate' area with sheet metal so I could mount 6 4.5W LED's - and on the top are 2 switches - one for 2 of the LED's and one for the other 4 (it's really nice when we stop in the middle of the woods in the pitch black to have just 2 LED's on to light up the area, without having the ignition on and wearing down the battery - the LEDs use so little power): short video here: I do quite a bit of night riding on those trails, and the LED's really fill in the dark areas. I ended up using the stock plastic number plate when I put 4 LED's on m son's KLX. I didn't want to drill 6 holes in my number plate plastic, but his was pretty beat up already, so I had no problems drilling holes in it.

With the 13/47 gearing, I'm usually in 2nd or third on these trails, unless it's a really steep hill (the one at the start is pretty steep, but doesn't look as steep in the video.)

 

We put a 13/49 combination on my son's 2009 KLX250s and didn't have a problem with the stock chain guide/guard. I have a Moose racing (stronger than stock) lower chain guide on mine and had to dremel out a little slot (about 1/4" deep) in the upper plastic guide for the sprocket, otherwise the sprocket hit it.
