Is that with a speedo corrected or GPS verification? This is sounding promising. Does the 13.42 set up improve bogging in 2nd gear?

13/42 is buzzy at 70mph per the GPS, but not going to hurt anything. 60-65mph is great.

It really improves the low end. If you care more about dirt performance than highway, it's a great setup.

That's it then- I'm going to go with a 14/45 set up asap. I will keep a 13t handy if the ride is looking tough. I have read that a 13t sprocket will increase wear on the chain/front sprocket, but by how much? So I'll play it safe and go back to the 14. Now....how many extra links am I going to need? I have access to a OEM CRF250L chain so I can get extra links, now I just need to get two master links....

I have a properly calibrated speedoDRD. I also agree a little with your comments on a 14 .... my next set will be 14/48
I do not use my bike for commuting so If I can cruise at 60 that's fast enough for me.

We have a CRF250 L at work that is set up with 13/48 sprockets; man this bike is insane! I have climbed wet muddy/grassy hills that I would never try with our other work bikes (crf230L's). VERY buzzy on road, I think I will swap out the 13 front sprocket (on our work bike) for the oem 14 and see how that goes on the road...hmmm...ahh yes, the eternal sprocket set up question. Almost as exiting as the "what oil do I use..." !! Well, at least I get exited about the whole sprocket thang. Not so much for the oil thang anymore....As long as my personal CRF250L can cruise at 90KPH and handle the occasional car passing speeds of up to 110kph, then I will go with the gruntiest sprocket set up possible. I am not blessed with a trailer (or vehicle to tow the trailer) so I have to ride to my adventure sites!

Just one extra link. For every 4 teeth you add to the sprocket combo, you need to add one full link to the chain.

That assumes the same size rear tire. Often the rear tire is changed in conjunction with the rear sprocket. I went from 100 to 106 links when I changed the rear sprocket from 39 to 48 teeth, and, changed the rear tire to a Dunlop 606 120/90 from the previous Pirelli 21 120/80.

That was on a CRF230L; your mileage may vary.

To be safe, I bought a 120 link chain and cut it down once I found what I needed. With another master link I used 5 more links to turn my old chain into an emergency spare chain for the new configuration.

Well this explains why some people say you can put 13/43's on with the stock chain.
I put on 13/42's and I know I could not have gone with a 43 but, I also put on a IRC TR8 Battle Rally 4.50x18 tire on there wich is a lot bigger than stock. Next time I will get either 4.00x18 or 100/100-18.

Right - 4 teeth per link is what you need to keep the axle at the same position. If you want to move the axle back to make room for a bigger tire, that'll require more links - and adjustment room in the slider mechanism, brake caliper, etc.

FWIW my KLX250 subframe looked just like that. Bikes and parts here in Malaysia are big bucks but welding is good and cheap. They ended up taking about 3" of rolled steel that was slightly larger inner diameter than the subframe and grinding it down till it just barely fit and welded it back with that reinforcement in the center. Then they added cantilever type flat pieces of steel under the frame.
I've almost always got a heavy Givi box on the back of my bike and that weld job held up for thousands of miles. Going thru Thailand, Myanmar, Laos on a 6K KM trip that was at least 25% washboardy type off road I weighed the box and it was 17 kg or 37 lbs!

My guess is at most it only added 3 lbs to the subframe... probably less.

My bike experience has been street bikes only, crotch rockets. I realize dirt is different, but i felt like an ass dumping the bike all day.
It does look like you had lots of fun though! Thanks for being willing to share your stories for our entertainment! :)

The series of DVD's here is really, really good for learning to ride in the dirt:

Ned has a way of making his points simple, easy to remember. It's short but you should watch it several times; watch the whole thing once then re watch the first section then go out and practice it for several hours.
