Honda XR250 Exhaust & Airbox mod

Basic mods for the XR250 owner

[@TheTrapjaw]

Congratulations by the work and the way to show it, without secrets and of clear form. As this video is of year 2007 not if your account remains open, but Podrias to raise but videos like this. Greetings from Argentina.

All XR250's are single cylinder, this has two header pipes because it has two exhaust ports. And also by drilling into the spark arrestor plate it is just relieving back pressure.

[@dhensley316]

If you take out the baffle, it'll be really loud. I'd say drill the baffle like this guy, and grind welds. I've also seen people drill holes in the exhaust tip itself. Either way, jet that bike, and don't be afraid of jets, they're easy : )

[@888comms]

love the music ... love xr's !!

[@RideWithTheWolf]

This video doesn’t even have anyone talking and it was more clear on what to do.

[@dhensley316]

I think he meant the spark arrestor plate where he drilled the holes.

[@greenstreak750]

I agree with rejetting. That lean condition will burn up your motor fast.

[@williammayerhofer9887]

Holy crap 16 ys ogo!

[@SuperBikesince1977]

Thumbs up to you too!

[@123ewq]

by driling the baffle, is it still spark arrested. what does he mean by holes in end plate at 1:42 thanks a bunch

[@predxene]

@NAMTRAMP he is not taking out the air filter the air filter is lower down. he is pulling out the snorkel witch will help if you were going in deep water, and the exhuast mod will relive back pressure. and thease bikes come really plugged up . i know this from exp. i have one.

[@milodaman2]

@ollecarlsson Lots of people have good new bikes and then they have projects that they like to have. I want an older bike so I can learn how their engines work, etc. Plus, it gives me the chance to restore an old bike to new.

[@crf250xrips]

so when u pull off the airbox lid crap dosent get in there????

[@SkydiveHake]

- correct, but its a 4 valve engine. i got an 1986, these are great bikes

[@gmanpeterson381]

it will give you more power but you need to rejet after all of that

[@volatilefists]

i brought a xr250r had no airbox lid. went to go trail riding with the boss, just the splash from a short tractor track completely drowned the bike. Lets just say im in the market for one of those so hang on to it lol

[@DoverVintageRiderSBR]

@Xxslayer410xX I'm going to take a wild guess and say that this is free if you have the tools and an aftermarket silencer/exhaust is 200+

[@156TYSON]

so what you are saying is that the xr250 is made for driving in waist deep water?

[@frederickak]

If you don't rejet your carb, you are sure to fry your engine by taking the baffle out and opening up the air box.

[@modcit]

Yes, actually it is. Trust me, it can!

[@4wheeldrifting]

do you have any idea how many dollars and man hours honda spent during R&D of that bike to get the tune just right??? Neither do I but it sure was a lot damn longer than it took you to undo it.

[@leemartintaylor]

There are no twin cylinder XRs. You're probably looking at the exhaust, it just has two exhaust ports. All XRs are single cylinder

[@dylanrice7075]

How many chickens????? Xr does have 2 exhaust pipes it was for performance ya 🤡.

[@IHyRaXI]

Hi i just bought a 1995 xr250 r and it is all stock. I want to remove the baffle so do i just remove the baffle and start riding the bike and not put i t back in or do i need to drill holes like this guy and put in back in? thanks.

[@markreiber4457]

So after all these years did you ruin your bike if you did these modifications?

[@fladam1994]

are there two exhaust ports then for this bike? i though it was a single cylinder?

[@2strokesRuleeee]

It is🤦‍♂️

[@rduncan999]

1). Rejet... If your increasing your air flow increase your fuel... lots of help online. 2). When you take the snorkel out Insert a large oiled section of foam there so it prevents you from having to clean your air filter after every dusty/muddy ride. 3). If your going to do these mods for the reason of performance make sure you run 0% ethanol and the highest grade of octane. not doing so will result in over heating or bending valves...

[@heinrichvonkekelnazi393]

robert duncan Rejet properly, and overheating will not be an issue. Of course, you can always run a leaner mixture, and put an oil cooler on the bike -- or even a big oil reservoir. They help with heat a lot.

[@Superbeta74]

jajaja, competent mechanic?

[@oaioaii]

Dont forget to rejet the carb after those mods or you'll run lean.

[@brettkovak6344]

oaioaii what is the proper jetting after these mods?

[@Ringtail95]

Yeah take the lid off the air box so dirt mud & other shit can get in good idea I'm so gonna try that

[@brettkovak6344]

Ringtail95 he forgot to put screen over it! Ya can also seal from the fender to the top of the air box as well.

[@RideWithTheWolf]

what he said. make your own screen. i’m thinking of making a custom air cleaner too.

[@badgumby9544]

My "completely stock" 90 XR250R runs extremely well the way it was designed. Spend the time wasted doing this shit by riding more. That helps going faster than un-necessary modifications. Honda designs motorcycles for a living. You don't.

[@totto210]

xr250 1996---- aclarar yanque nerd. -1

[@natemercure1770]

totto210 same

[@braydenahl660]

I got more power on mine by removing the whole spark arrester.

[@emmabedell5717]

COOL

[@chadmalugin185]

Loud pipes save lives

[@markreiber4457]

Does your bike still run ? Did it ruin it?

[@diegomr6969]

step 1: please DONT STEP MORE
