One of my hobbies is oil analysis, so I can speak to filter efficiency (ability to trap dirt). After looking at hundreds of oil analysis reports and experimenting with my own car and bike, I can say that oiled foam and paper both have excellent efficiency (if the foam is oiled correctly). Oiled gauze ranges from pretty good efficiency to awful depending on how much oil is used. Both my car and bike had paper filters OEM, and I had lots of good baseline oil analysis reports before switching to UNI oiled foam filters and BelRay foam filter oil. Silicon and wear metals were no better or worse than paper after switching to oiled foam.

The problem with oiled foam and gauze is that it's very important to use enough oil and distribute the oil evenly throughout the filter. Also, the oil has to be thick enough that gravity and air flow don't force the oil away from certain parts of the filter. I'm going back to the OEM paper filter in my car because I'm sick of cleaning and oiling the foam filter.

I don't have any experience with the "viscous" filter Honda is using in the CBR250R and CRF250L, but I suspect it's very efficient. In any case, I would not experiment with non-OEM air filters without having a good oil analysis baseline with stock so that I can verify that the new filter is working. Dirt is extremely abrasive stuff and it doesn't take much to do a lot of damage quickly.

I agree; I trust the OEM paper filter designed by Honda for the CRF250L. Uni foam filters are good, as are BelRay and No-Toil filter oils. However, Best Dual Sport Bikes has designed a new filter cage for their Uni foam filter, and I am not sure it will properly seal along its edges.



In contrast, you can see the edges of the OEM paper filter are lined with foam, and the inside of the filter has a square notch which inserts into the opening in the air box.



I would better trust a foam filter cage which is designed with the same base as the OEM CRF250L filter. Perhaps No-Toil, Uni, or another vendor will design such a filter cage in the future.

Hmmmm... what to do.

Now that I see a close up of the Uni prototype, it looks like a plate has been devised that it covers over theair box inlet and adapt an existing element that'll go in the box....so far not an optimized solution....Paper without the backfire screen seems a better intermediate solution

That's exactly my point, Ed.

Does anyone know the torque value for the 2 front sprocket bolts?

Thanks!

Is this the red gripper carbon?

I don't think this review has been mentioned in this thread. Motorcycle.com just posted a comparison between the Honda CRF250L and the Kawaski KLX250S. Here's the video summary of the comparsion.



Here's a link to the associated article at Motorcycle.com.

http://www.motorcycle.com/shoot-outs...ampaign=weekly

Motorcycle.com says the Honda suspension performs well enough compared to the Kawasaki. Therefore, the lower price of the Honda CRF250L, combined with its high tech, fuel injected engine, makes it the winner over the Kawasaki KLX250S.

They called it the Red Carbon, which is on the sides. The black gripper is on the top.

Question to any owners who have ridden the crf250L offroad in the desert, how does it handle whoops? Compared to lets say the drz400 or dr350's suspension. Im really looking to upgrade my old xl250 which is not in my eyes worth rebuilding the suspension and putting money in to when a brand new bikes is so cheap and most likely much much better.

I guess my main question is how fast can you comfortably go offroad on the crf250L on a not smooth road, I've seen some review videos posted hear riding in southern cali trails but the didn't comment enough on its limits and Big Bear, Johnson Valley, Red Mountain are the areas I want to take it.

should ask this in the owners thread might get a better response
