Helping The Gen3 KLR 650 Breathe! (De-Snorkle & Slip-On Pipe)

The KLR 650 wasn't design to win any races. But that doesn't mean we can't get a little more wheelie popping power out of it! In this video I help my Gen3 KLR breath in and out a little easier. I also compare the results against a previous control test to see just how much of an improvement the changes made! (Check all your local laws before making any modifications to your motorcycle!)

After removing the snorkel and adding the Lexx slip on, I installed the Power Surge from JD Jetting- to add some more fuel- and what a difference that made. Finally, I used a hole saw to install two nice holes in the top of the air box for good measure. It’s definitely made the KLR more fun on my freeway commute. It’s still not fast, but it’s not such a turd on the highway. Totally worth it.

I like your videos. I've had a Himalayan for about 5 years and I've ridden it all over, but just yesterday I got my new Gen3 KLR. I have about 90 miles on it so I'm not hotdogging, but boy howdy does it like to go. I can tell it's so much more powerful and capable than the Himmy. After a few thousand miles to get acclimated, I might even try parts of the TAT.

Watch your head pipe now Swank! Without a tune and more fuel, she'll glow red hot and melt your coolant over flow tank--nipple for the line in particular. I'm running a JDJetting PS6X on my 22 klr with petty good results so far.

Thank you for conducting this highly scientific study. I see people in the FB pages remove the snorkel and was skeptical.

[CrackedTth]

The biggest thing you can do for your 3rd gen KLR is modifying the flow rate for your fuel injectors on your bike's computer. Even if you don't modify anything else it can still increase performance.

After 1400 miles on my 22, something was just to vanilla about the bike. I bought a Delkavic 9in. Carbon, WOW!! total game changer. It just makes the bike so much better. I admit it's on the louder side of life, mainly on start up until it settles. You can't beat a Japanese single with a pipe, sorry KTM. thanks

[bricetetrick]

Good stuff as always!
I love my old klr, I bought it new in 09 and have done crap loads of upgrades to it, I also own a T7 and believe it or not I prefer the klr.

[StandFast]

Thanks for providing links to your gear, your outfit along with the helmet look really nice. Keep riding friend!

[Bugoutnow]

So what was the result of these modifications..power gains? Better/worst fuel mileage? Annoying residence or frequencies well driving ? Would you do it again or spend the money on suspension and rider comfort?

[johncoleman]

Gen 1 here, nice to know of any mods that might help. For the $, just about do anything, hard to beat the "cockroach" of motorcycles. Good one, thank you, 😅

It's about time someone runs an article about their engine mods to the 650 that will really "Hot Rod" this KLR 650 engine half way to Europe . I have read over 6 or 8 articles regarding accessories etc for the KLR . Now, lets have some engine mods to increase power . We need the expertise from some of the "Prostock Drag Race Guys" for some really good ideas with engine mod's to increase power .

[berttompkins]

Those a common mods to any bike. But I repeat myself (SORRY) but the "torque" header pipe was drastically reduced in diameter on the gen.3 F.I. manifold. I believe it was really reduced to increase velocity and heat on the 02 sensor. The 2018 header pipe is massive in comparison but has no 02 sensor.
I was hoping you would have done this simple mod as it dramatically makes incredible change to this engine . It is a short stroke, 4 valve twin balancer engine . You must only drill a hole and weld a matching thread metric nut on top of the pipe and put the 01 in. Only loosen the right side fairing bolts up near the radiator to wiggle the fat pipe in. I spent 50 bucks on ebay f or a used pipe..
This whole system w Lexx pipe and your intake mods will double your fun. Then the 16 t primary gear makes this bike a F LYING PIG. NO illegal reflash required.

Thank u sir. Very good information, and that countryside is bee-u-tee-ful! Hello Wisconsin!! 😂

[Havocs]

Thank you fellow Wisconsinite! I had an older KLR650 with the carb. I bought a uni Two Brothers muffler for it. Would you say that the Fuel injected version is better, same or maybe worse than the old?

I have a simple and cheap mod to share, primarily for KLR's up to 2018 model year with out EFI, and likely would also help newer bikes with EFI to some extent. I almost always use REC 90 fuel in my 2015 KLR down here in South Florida but in hot weather and sitting in heavy traffic the bike started to misfire upon acceleration until it cooled down while riding. (I am an ASE certified auto tech). It drove me nuts at first, I replaced the ign coil, crank position sensor, to no avail. I finally surmised that it was getting vapor lock and the exhaust pipe runs real close to the carb (and the heat shield only protects your leg from excess heat) so as a "test" I decided to wrap the front exhaust pipe (along with the heat shield) with heavy duty aluminum foil from just behind where the front end of the heat shield, gave it 2 wraps with "shiny" side against the pipe and secured it with some stainless steel fishing wire in 4 places. And low and behold it cured the problem, and the bike even seemed to have more power and throttle response! This makes sense since heat in the air intake system (and fuel) is the enemy of horsepower, the cooler the intake air and fuel is the denser it is causing a more powerful combustion. to keep it from looking crummy I masked it off and painted the foil with high heat black paint, I purchased some exhaust pipe heat insulation "wrap" to replace the foil with but it's been 3 years and the foil has worked so well I still haven't removed it to use the exh. wrap instead. I am not sure but it looks like the exh. pipe on the EFI bikes is not as close to the throttle body as the carb is on the older bikes but anything to keep excess heat out of the intake air is a good thing and requires no other mods.

I want the 3rd gen, really like the green this year, but not available in Kanukistan😭

[crash]

For under $500 the KLR can be a dirt road monster!

[alexmaccity]

Mines straight piped. I'm running the stock airbox

[MrPepper]

Whith the Lexx slip on and snorkel removed have you looked at the spark plug to see if it running lean or rich ?
