I slightly modded the KLX PICS ADDED!
 

I'll take pics tonight or tomorrow, I did not have any time yesterday. I also owe you all pics of the new little trailer, again no time yet...

In prepping the KLX for a big upcoming dual sport ride and some light adventure touring this summer I fitted a very nice rear rack and a very heavy duty skid plate.

Somewhere down the road I think it will receive a pipe and jet kit. I've seen real dyno numbers for a HP increase from around 20 to around 25 with those mods. 5 HP may not sound like a lot until you think of it as a 25% increase AND a weight loss of a few pounds, maybe enough to offset the increase from the skid plate and rack I just fitted.

Andy ordered us Two Brother's pipes and Dynojet kits. It's gonna be Rock and rollin' soon! :P

The pipe, and jet kit is well worth it. I would also recommend getting rid of the backfire screen, and airbox lid while you already have the carb out.

I was planning on keeping the lid but removing the snorkel. I've heard it's kinda loud without the lid.

A 5hp increase is a considerable amount for a 250. I'm surprised that there's that much power hiding in the muffler.

Does Uni make a filter to fit the stock airbox?

They do but the popular opinion on the various forums is that it is not needed.

I've seen dynos that the jetting and the pipe each add 2-2 1/2 HP individually or 4-5 in combination. In stock form the bike is so heavily restricted. I've heard ceiling fans that make more noise than my KLX :? .

Wait to you hear my "Q" With the NEW Pro Circuit Pipe. Loud and Proud. LOL - Well shouldn't say that becuase I really don't know yet but will tommorrow. Put the EW Battery in her today and she's been on the battery tender most of today. As long as it's not raining tomorrow's the day. Definately will have video for ya soon. It will be posted in my Pipe install thread. Can't wait to see the Kawasaki Pitures. We all like pictures and videos.

I'm glad your Q is ready to rock! I hope the weather cooperates, be careful out there I bet ther's going to be a lot of sand, salt, gravel etc to slip on. 8O

I currently for the first time in years have no Q in my life. :(

My buddy Roger sold his today for more than he paid for it new! 8O

He bought a 2005 KLX300. :D

Thats good - That means they hold value. I fOUND ONE ONE ON eBAY TODAY - It's an XF Model - They want $2799.00 Plus sshipping dealer feees, prep, etc....I paid $1395.00 for mine and that was total with FREE Shipping right to my store. I am very happy I bought when I did. I think all bike prices will once again go on the rise since the price of gas is rising. There will be alot of bike purchases this summer I believe. It's proabably a sellers market right now.

We eagerly await further updates, and photographs, Doc! :D

Spud :)

Sorry about the quality of the pics and the fact they were flash at night. I've been working so hard I've not had hardly any free time.

Here's the rack and the skidplate on the KLX. They are very strong, were easy to mount, and look like they will serve me well:

I mounted a new tire on The Dirt Rat. Andy suggested and ordered me a Bridgestone motocross tire for soft/intermediate terrain. Since this tire will never see pavement it seemed like it was worth a try:

I have acquired yet another perpetual loan KLR650.

I will be taking The Dirt Rat to the Juniper WInlderness Sand Dunes on Saturday and this tire looks like it will do well out there. The only thing that is more aggressive I can think of would be a sand paddle. Roger will be taking his new KLX300 so we will be breaking in my 'new' trailer.

Each time I mount a tire I swear I won't do another one. This one was not too bad though. About an hour from starting to take the wheel off to the test ride. The tube was a Dunlop so I reused it after a thorough inspection.

The rails on the trailer can be placed in any of the three positions. I have one in the middle because I will be towing The Dirt Rat solo to Rogers. Then we will move the rails to the outsides to mount his KLX300 for the rest of the ride to the sand dunes. I hope to fabricate a third rail soon so I don't have to be moving one back and forth.

Holy Kawi stable! 8O You must be living well.

Maybe you could find another XR rim for cheap on eBay and mount a paddle on it. I see good used paddles on CL often.

The trailer looks good! Bonus that you can move the rails around for now.

Thanks for posting the photos, Doc! :) The new rack and skid plate look great. Is that a Ricochet skid plate?

After I stopped changing tires on my knees, I actually enjoy changing them! I strongly encourage you to get a Moose Racing Tire Changing Stand, or its equivalent. ;)

Spud :)

The idea for an extra rim is excellent. I'll see how it does on this tire but will consider a sand paddle. I've never ridden a bike with a paddle. I don't know if my OHC 200cc Lifan has the power for one though :? .

The deal on the KLR's is that if I store and maintain them, and Rand can take them at his convience, I can ride them all I want. Rand is the president of the hospital I'm affiliated with, and is very good at physician relations!

It looks like a good investment. It would save my knees and my back... Andy is a dealer for Moose products so maybe I can have him order me one. :D

do not remove the screen in the new pipe, if you do it will not be park approved and you could be fined for riding it in a public park..

on a better note, that new pipe is going to really really clean the look of the bike up.. that stock muffler is like well a stock muffler, its restrictive, heavy and ugly

I plan to leave the spark arrestor in. It would not take much to set dry sage, bentgrass and tumbleweed alight 8O .

I've read and seen dyno reports that a pipe and jet kit cause measurable and felt horsepower gains. To be honest though I will miss the stealth of the original pipe. This bike is as quiet as a ceoiling fan in stock form. :D

Git 'er done! :P

70 bucks seems kinda pricey to me. If it were me, I would get some C-channel and cut a "V" notch on the sides and bend up. Weld the notch back up and anchor the same as the store bought rail.

I thought $70 seemed OK. :cry:

I figure the steel would be pricey to make my own, and add in time, travel to the store and to my friend's, and getting him to do the welding, tax on materials and gas for the pickup this was a good way to go. Plus being ready made it will save me a few hours, including painting, travel, and construction. :wink:

hey doc have you check rocky mountain for that rail ? they might have one slightly cheaper then that

Factoring in labour and time, that's a cheap solution. :D

Painted trailer, turned out good. It should be able to resist the sun and elements for another 20 years now. :D

My Two Brother's Racing exhaust and Dynojet kit should be here today or next week. This should really wake the KLX up. And my neighbors too, I'm afraid... :roll:

My Two Brothers Racing exhaust and ynojet kit are in. Andy already installed it on his KLX and said it is LOUD. If he's a racer and says its loud I bet it's loud. Not sure how I'll feel abotu that... 8O

im sure two brothers racing has a quit core inscert or something like that for it...

Quiet mufflers are greatly underrated, Doc. ;) Perhaps you should listen to Andy's exhaust system before you open the packages for yours. ;)

Spud :)

If the performance increase is worth it, you could try a DB dawg. http://www.dnamufflers.com/Ignition/mufflers.html

Andy's bike sounds great! :P

I might be able to tiptoe out of the neighborhood without waking anyone up...

There are tips I can add for less than $40 that will lower the sound up to 8db with no loss of power, I may get one. I'll see.

I dropped the KLX off at his shop and we will kit mine after work tomorrow. I'll be sure to bring my camera id you all want pics.

His bike does rock now though. The power difference is very obvious.

Lacking a dyno I will compare top speeds and 40-60 top gear full throttle pulls on the same section of road on windless days.

Top-gear roll-on 40-60 mph before mods: 7.4 sec
GPS top speed in a tuck before mods: 87 MPH

Not bad for a little 250! :P

We'll see what she does after the mods.

BTW the TBR is 9 pounds lighter than stock with no catalyst. :D

If? Are you new here? Yes, we want pics! :D

I'll bet the elimination of the cat is the biggest reason for the power increase.

Duh! :roll: What do you think? :lol:
Holy cow; 9 pounds! That is a terrific weight loss! :D

Spud :)

It's a heavy stock muffler to be sure. I added a few pounds with the rack and skidplate but I bet I still have a decent net weight loss.

I wonder how much I'd lose trading the stock rear fender and light for an Edge II...

I was very pleased to lose 9 pounds from my XR650L by relocating the battery, and eliminating the battery box. :) XR650L owners who replace the entire exhaust system only drop 3-4 pounds from the bike. ;)

Spud :)

Does the BRP have a cat in the exhaust? The TBR is aluminum and magnesium. It is pretty light. Andy bought the carbon fiber one which is very cool looking, and I'm sure a little lighter still.

I don't think the BRP has a catalytic converter in the exhaust, but I don't know for sure, Doc. I must admit, I don't know much about catalytic converters. ;) The stock, XR650L muffler is supposed to weigh 7 pounds. The FMF, Powercore 4 weighs 5 pounds, and the FMF, Q4 weighs about 5.5 pounds. I think the difference between the FMF, Hi-Flo header, and the stock header is about 1-1.5 pounds. If you can drop 9 pounds off the KLX with an aftermarket exhaust system, I say go for it! I wouldn't care how loud it sounded! :D

Spud :)

I am probably getting old, but I would rather it just came with quiet insert if no power loss.

Andy weighed the stock exhaust and he said it was almost 15 pounds!

Now that I think about it my weight savings may be less. I ordered the aluminum can and Andy paid the extra cash for carbon fiber which is likely a little lighter. Either way I'm ahead in terms of weight. :D

I may add the quieting piece...

I do quite a bit of 'mild' trespassing (railroad property, Irrigation District property) where I ride and I don't need the attention... :wink:

With that said, people have been hunting, riding bikes horses and 4 wheelers on these trails for decades and I've never heard of anyone getting in trouble...

I just got a new muffler on the ranger. Sure nice not having the drone and the leaking exhaust under the cab.

I had a crf150r exhaust on my lifan. It was loud. Great for performance, but commuting got old.

The elite is nice and quiet.

I like nice and quiet also. Maybe the tip will be a perfect comprimise.

Glad the Ranger is fixed too. :D

I agree with both you gentlemen; I prefer quiet exhaust systems. :) However, I think losing 9 pounds off the KLX250S will make a big difference in handling. I think adding a quiet insert is an excellent compromise. ;) I am still amazed that the KLX exhaust system weighs 15 pounds! 8O The entire Honda, XR650L exhaust system weighs about 9 pounds. My Zongshen exhaust system weighed 12.5 pounds. 8O Do catalytic converters really weigh that much! :?:

Spud :)
