KTM 300 XC-W Top End Rebuild | Part 2: Power Valve Rebuild

[@williamdurr7792]

Two critical pieces of information missing in this video, in my opinion, that might make a difference for you: 1) on left PV flap, leave the middle (guide plate) screw alone and you don't have to reset the Z dimension. It it will remain locked in its current setting. If you're happy with how your bike runs this is one less thing to worry about. 2) I had to put the exhaust flange on first before I could put the geared guideplates back on. When I tried to do it without the front exhaust flange on, the plates would not go on properly. They should almost drop in. My PV was so tight I could not move it till I did the exhaust flange first. Slavens Racing has a video that complements this one very well. Thanks to RMATV for these resources!

[@crluke14]

So would that be to leave the centre Allen key one in situ ?

[@williamdurr7792]

@crluke14 Yes, the middle one, correct. The slavens power valve video describes it.

[@crluke14]

Thanks . Did this last night and it saved me the reset issue. Much appreciated

[@honsdaa3171]

geared guideplates what part are you referring to??? how they call this part you mean in the video... i am not understing what is this part are you explaining

[@myronstambaugh761]

Also, no need to put the o-rings in place until you are ready to put the exhaust flange back on. Thank you RMATVMC for the instructional videos. I have used them many times.

[@rmatvmc]

You're welcome. Glad to help!

[@rustyshackleford653]

So say you were to take apart your power valve and forget which gear plunger thingy goes on the left and which one goes on the right. ( Not that I would be careless enough to do such a thing of course) Does it actually make any difference which one goes where? They both look the same...

[@rmatvmc]

Hey Rusty, that's a great question that I didn't bring up in the video. On these models the left side (if sitting on the bike) plunger/gear will have a "L" stamped into the outside. The rights side will be blank. Hope this helps!! -Chance

[@MainJet158]

Can you make a video of the 2019-2020 power valve z adjustment. The newer power valve does not have a stop arm. Instead it has a screw and a jam nut.

[@clutchitsystems100]

I'm stunned. Great job, guys!!!

[@rmatvmc]

Glad you enjoyed it!

[@craydonrice5375]

Where can I get that power valve timing tool from? I live in the Uk

[@Leon-ht4hw]

Should you be able to move the power vavle freely when done?

[@willhernezemilysbro]

I am able to move mine by hand when done.

[@bizzidy]

Will the timing tool work for a 2003 KTM 300 exc?

[@carlossg4193]

Hola!Es igual el control clap de una exc 250 y una exc 300?Tengo un cilindro 300 y quiero ponerlo en mi KTM 250, ¿podré usar todas las piezas del exhaust control?Gracias.

[@SeparadoresAtecon]

Any other way to get the timing correct without the special tool?

[@hayes831]

you can use a set of calipers. spec is in the owner's manual.

[@klxklr]

Nice work. I wonder how much different the process is for a Beta 300 is?

[@rmatvmc]

klxklr, the KTM 300 and Beta 300 motor are very similar. This video should help for the majority of your rebuild, but I would definitely check with the Manufacture to get specific details, torque specs and procedures to verify it's done correct. - Chance

[@RC.56]

When deciding between a 23 300XC or 350 XCF, what are the maintenance differences between the two? Besides oil changes, is there one that’s more difficult to work on or maintain properly? Thanks

[@rmatvmc]

Most people find two strokes easier to maintain. The top ends are a little easier and no oil filter to swap. I would base it on what you are going to ride over maintenance. If you're doing mostly hard enduro, 300 for sure. If you're riding a good mix of everything, the 350 will be awesome! -Charles

[@kathrynmccoll-chute6795]

now I will go ahead and thank you for these videos! well go ahead and start our disassembly and well go ahead and get our parts on order!

[@robertrobson4306]

Hey mate, What’s the inside distance between two edges of the tool for tpi 250 2018?

[@duken4evr]

Nice detailed video, thank you!

[@seb42]

Is the xcw 200 (2014) the same motor layout/design?

[@k-dreezyl6050]

What are you using to scrub the parts?

[@rmatvmc]

Motorex Power Clean and a red Brillo pad 👍

[@Feragho9]

Do you have any tips or tricks on how to get the flange off? Mine is very very stuck on and I dont wanna hit it any harder than I already am. It hasnt even budged. And yes I did remove the 4 allan bolts before. Are there others that werent mentioned in the video? Thanks

[@rmatvmc]

The only things holding the flange on are the 4 bolts that you mentioned you removed and some silicone. Does it look like there is a lot of carbon buildup that's maybe making it stick?

[@Feragho9]

@@rmatvmc The power valve flap looks a bit gummed up hence why I want to get to it so thats perhaps why its stuck. Would heat or some sort of homemade tool help to get it off?

[@rmatvmc]

You can definitely try penetrating oil or some heat and tapping around the flange. Also, if you aren't already using a synthetic premix (something like Maxima K-2) that will really help reduce that kind of build up in the future.

[@larrytucker1945]

Are you using the Belray waterproof grease for the power valve reassembly? I’ve never been sure if it is appropriate for such applications. Thanks! Love the videos.

[@coryperemsky]

Are the Tusk parts any better quality these days? Last time I used one of their clutch levers and a clutch pack (5 years ago) it was sort of horrible... I only ask since I see RMATV pushes them pretty hard. Nice video.

[@rmatvmc]

We're constantly looking to better any product we sell, this bike has 400+ hours on all Tusk gasket kits and other test products. You should definitely give them another shot, you won't be disappointed! Thanks for watching! - Chance

[@dawidwacuu]

Whats the Z-DISTANCE for KTM XC-W 300 2018? :)

[@Temppaa98]

What did you use to clean the power valve?

[@rmatvmc]

It looks like we used Motorex Power Clean and some contact cleaner for the cleaning of the power valve.

[@Jess-db3yf]

Love these vids!

[@rmatvmc]

Thanks for watching Jesse! - Chance

[@davidsugitanoto4708]

Is it support for emission euro 4???

[@adambatchelder4121]

For 2012 to 2016 the Z dimension for a 250 is 48mm, for a 300 its 48.5mm

[@zachthompson5670]

How do you take apout the power valve?

[@rmatvmc]

That is what we show in the beginning of this video.

[@scoptimusprime7382]

Great vid! I got a lot out of it!

[@Temppaa98]

where can I grab one of those timing tools?

[@rmatvmc]

The first link in the description will take you to a page with all the tools and parts used in this video. You can also check out the Nihilo Concepts Deck/Timing Tool here: www.rockymountainatvmc.com/parts/nihilo-concepts-deck-timing-tool-p

[@TSOLification]

do you have to do the exhaust value ? like everytime you do a top end?

[@rmatvmc]

It's definitely safer to check it out and clean any carbon deposits or anything like that. You wouldn't want to do all that work just to put it back together and wonder if you should've cleaned it up better. Thanks for watching!

[@Mike-or7xv]

Rocky Mountain ATV MC how would I set the power valve “z” measurement without one of those tools?

[@MrQueLastima]

What method do you use to clean the carbon build-up off the power valve? That stuff is stubborn.

[@6cooks68]

how can you stand to use that Craftsmen ratchet?

[@balslammerracing14balser95]

Got a link to the tool ?

[@rmatvmc]

The first link in the description will take you to a page with most of the parts and tools used in this video!

[@balslammerracing14balser95]

Doesn’t show a listing for a 250 or 300 only goes to 150

[@balslammerracing14balser95]

Don’t list the decking tool for the 17 250xc eirher🤷‍♂️

[@riadv88]

Awesome 📹 thanks a lot . Where can I get the timing tool that you used 🤔?

[@riadv88]

To measure to power valve height?

[@TheDylantaylor08]

Just tried to order the Nihilo Concepts deck/timing took that YOU used in your video and you don’t carry it for a 300 KTM motor! 🤣🤣

[@chrisgall4664]

Yeah same with me! WTF!

[@NirHason]

You can get it from here: nihiloconcepts.com/products/timing-deck-tool-ktm-husky-250-300-stainless-steel-09-19

How many time do you say “go ahead and”? Many.

[@sidecarbod1441]

28 times, you're welcome!

[@oliver5872]

Hi, Great video! Got a question regarding the boost port valves. Is it normal that they don’t work the same on both sides? Or did i do something wrong when reassembling it? Made a video: kzbin.info/www/bejne/bprPkISngqyoh6c One is open when flap is open, but one not. Thanks for help!

[@anunentitledmotivatedmille7731]

Yes

Chance is cooler..

[@Jay58649]

Does the timing tool work for 2015 300s?
