SNIP Arden, what jet size do you run ? I put in the 140 to go with my Big Gun pipe, but since I canned that thing and went with the Laser, I'm thinking I may be jetted a bit rich? Maybe I should use the 136?

Also too, the K&N WILL clog and choke out your engine under the right conditions. I got off track a bit on a dual sport ride and ended up buried up to my frame in sand in a wash south of Ocotillo Wells, and all the dust I kicked up trying to get out of the wash went straight into my airbox, where it eventually completely clogged my air filter and caused my KLR to shit it's pants. I had to yank out the filter, scrape it with a swiss army knife, and beat it on a telephone pole just to get it to flow enough air so I could limp back to camp. Since then, I have taken to running filterskins (a pre-filter type of "sock") on the K&N to prevent that from happening. In conclusion, for a dualsport bike that sees lots of miles, I like the K&N filter, but for pure dirt riding (on an XR-R), I prefer a UNI filter. CA Stu PS I have seen clogged K&N's 3 times, so I know it's not just me, because I'm so special.

Gun pipe, but since I canned that thing and went with the Laser, I'm thinking I may be jetted a bit rich? Maybe I should use the 136? Stu, I'd have to check. If I changed the main, it was to whichever size came with the kit. Mostly it was a needle change and I had to drill a hole in the slide. If you changed to a less restrictive exhaust, you may well be running rich. I still get low 50's gas mileage with the stock exhaust.

>>> Also too, the K&N WILL clog and choke out your engine under the

right conditions. I haven't had that problem, but the filter skins sound like a good idea. Wouldn't hurt to have one handy. K&N claims their filters work better when dirty, but I guess you kinda took that to extremes. __Arden

140 main? The stock main jet is a 148 according to the manual. I saw on this persons site where he suggested a 160 main and a 42 pilot along with a backward L shaped hole cut on top of the air box. The hole diameter was 1" and the length was 3". This along with a Big Gun pipe. He commented if this mod is done, to hold on! I know when I did similar mods to my DRZ400s, it really woke it up. Stay tuned, because just as soon as I reach 1000 miles, I'm trying it! Ed A15

K&N filters suck, well... the problem is they don't suck. Air, that is. The only reason I stayed with them is their durable construction (and I stupidly knocked out the screen in my Tengai's airbox). The stock filter flows WAY better. Mark B2 (K&N) A2 (K&N.... some people never learn) A3 (stock filter)

Not to sound like a broken record about my friggin oil analysis, but silicon levels were well within acceptable limits. My oil filter? Stock, with Bel-Ray's blue filter oil. I ate a lot of dust that month, too.

My kit came with 3 jets: 136, 140, and 150 Stu

The biggest advantage to a KN filter is their life. You can clean and reuse them as long as you own your bike. If you trade bikes every few years, it probably won't be feasible. The KN also does a better job when they are dirty than a foam filter. Most stock foam filters can start to seperate at the seams in a short time after a few cleanings. I do not think you will notice a "seat of the pants" improvement. That being said, I have one in my truck and in two of my bikes... Bert Fox Elko, NV --- wilbur_lakeland_fl wrote:

There is no performance increase to be had unless your stock filter element isn't flowing enough air to feed your motor. I don't think that is the case with a KLR 650 motor. However, the positive side of a K&N is less maintenance. Also, a foam filter that is full of dirt will still allow dirt and air to pass through it, a K&N will not. Hence, your KLR will not run. That's why dirt racers run foam filters. Their motor will be rebuilt frequently, and it's more important to them to finish a race than protect their motor.

If you don't like cleaning your foam filter all the time, you're not planning to ride in horrendous dustbowl conditions for 500 miles in 2 days, and $45 fits in your budget, get the K&N.

SNIP Ouch! Could it be the owner is a lazy bastard and can throw a rock across the freeway and hit the K&N plant from his office? Stu
