RK Tek 2 Stroke Performance Head Installation 2017 KTM 300 XC - Episode 191

[@flamesomething1]

Thank you Dirt Bike Channel for finding this! Ordered mine this week and took two days to receive it! The fit and finish of the head is amazing! They asked where I heard of them and let them know it was you. Just have to wait for the snow to melt. Thanks for what you do!

[@DasChristoff]

my rk tech head will be here tomarrow. they asked where I heard of them and I told them Kyle from DBC. thank you for posting this video. had I not seen this I would have settled for something far less. keep the videos coming!

[@bryanroberts]

I'm pumped to see and hear about this heads performance!....Those graphics are looking good btw!

[@petrikurronen7175]

Greetings from Finland! Thanks for making these vids! Very detailed, quality information packs. Keep it up!

[@brutalianali7439]

Terve

[@jeremy_moto_192]

just bought me 2017 ktm 300 xc, first ktm ever thanks to dirt bike channel they convinced me

[@DirtBikeChannel]

Have you had a chance to ride it?

[@jeremy_moto_192]

Dirt Bike Channel yeah for like 20 min it's a blast, I got figure out the suspension though since I'm heavy 280lbs and 6'3 But that 300 motor is a dream

[@jeremy_moto_192]

Dirt Bike Channel I'm use to the 450 yzf and this bike is awesome

[@jeremy_moto_192]

Dirt Bike Channel I need to figure out the suspension thought I'm 280lbs:( I just need to lose weight

[@jeremy_moto_192]

Dirt Bike Channel the 300 motor is a dream I love got to ride Sunday for a little

[@joztunes69]

I sent my yz125 head to Rk Tek, I'm excited to see the results and how it will turn out

[@nateemmett4485]

Are we going to get a comparison of your '15 with the S3 head and this bike, or at least some chat about it? Thanks Kyle keep it up!!!

[@motoman5304]

3rd!!! Hey Kyle your are the man!! You have a full time job, make KZbin videos, and have a family and still has fun ripping on dirt bikes. It's insane

[@DirtBikeChannel]

Takes some good time management. Thanks for noticing.

[@enduro-parts-aus]

so good seeing the top of your piston and finding out you got your jetting dialed :)

[@jc123stickler5]

Kyle. 1) Maybe I missed it. Are you going to review the performance of this head? 2) How does it compare to the Slavens S3 head? THX!!!

[@DirtBikeChannel]

Coming later....

[@mikedaley5031]

Ya, Somender Singh figured out that groove thing some time ago. Theory is that channels of cooler fuel coming from the center of the combustion chamber follow the grooves clashing with the hotter outside edge with the squish band creating turbulence. Think more violent combustion. Yes, I have experimented with it on a tip from Lonn Patterson from Thunder Products Racing back in '08. Works as advertised!..

[@mikelyons7511]

To get all the benefits out of a modified head you pretty much have to do porting not just polishing, but cylinder head Port timing as well to get a broad spectrum of usable power for your situation. Which also pipe silencer carb and reads coming to play. Have a happy day, 3rd gear pinned forever✊

[@frostcold81]

do you like the RK Tek head better than the slaves S3? how do they compare? I have a 2016 xc250. strictly trail riding up in the great state of Maine. little bit of single track but not much.

[@rhtrps]

Kyle this is excellent!! I am no mechanic but I am mechanically inclined like you and would love to see more how to videos on things a do it yourself person can tackle.

[@EdwardStorlien]

Man I want a dirt bike like that so badly!

[@zachterry9244]

Great video. Shows really how easy this is to install. I have the same head on my 3014 Husaberg 300 TE. I absolutely love the extra power and responsiveness and WOW is it noticeable. Really looking forward to your follow up review. Love your channel. Keep the reviews coming.

[@DirtBikeChannel]

Thanks Zach.

[@banaanipassifin4159]

I bought a BUD racing head for my ktm exc 125. My gosh did it change the whole experience, the sound and power got a huge upgrade.

[@DirtBikeChannel]

Very cool.

[@banaanipassifin4159]

Yep, I was surprised how much it changed the behavior. Definitely better spent money than a new pipe or silencer.

[@DirtBikeChannel]

That is what I'm hearing from others too.

[@mariomessinese9182]

trinity racing did this mod to the domes, Harry called it the turbo mod.. Ocean pro heads for jetskis had it too , most say it's a gimmick.. or will cause detonation .. but my 750sxi ski has it done and has no issues

[@PolskiMotoVlog]

I really like your videos, very professional! Good job!

[@BlackHawk070]

:)

[@gearguy7877]

thats a awesome graphics kit u got it looks good

[@shadetreesurgeon]

Ah what a tease! Looking forward to the test ride man

[@DirtBikeChannel]

I just got to ride it on Sat. It was really good.

[@OffroadEffex]

Those graphics are on point!

[@DirtBikeChannel]

Thank you.

[@brimatum]

awesome! I live right up the road from there. its an awesome place to ride

[@jhutch1470]

They also ask what fuel you use. I just had a 110 octane blue one made for my 2018 Husqvarna TC250.

[@stumpinater]

@J Hutch, hows' the new RK TEK top end working for yu? I just put 5hrs on my new 18 tc250. i'm thinking about the RK TEK head. thanks!

[@jhutch1470]

I use Speedway "Cam 2" for the minimum 110 octane so far. I have yet to have the weather break for my riding season to start. I have ridden it down the street and have so far jetted it up 2 on the main and 1 on the pilot. I will see from there. The hit is hard and the power is awesome so far. I can't wait to see how it runs on the track.

[@jhutch1470]

It also does seem to have a lot of lower power and the power band is wider so I'm excited. for the money, try it out. Just be willing to use the race fuel for the biggest gains. I love the head to death so far and would buy another one in an instant.

[@racerx9223]

I could see the crosshatching in the bore of your bike still, it's fairly fresh!! All the bikes I've ever had were pretty wore in the bore, never got to see that before, funny I finally seen it on video where alot of detail is lost, good stuff though, I'll have a young cylinder someday!!!

[@SwabianBiker]

your workbench is great, which wood do you use for it? thanks for the great Video!

[@harm97]

Got to ride it last sunday and was realy happy with it,strong bottom end and midrange,engine response was fast and the jetting was improved.i had a weird knock in lower rpm when i closed the throttle after high rpm,Its gone now.Btw i have a 38 keihin wich also helps.

[@DirtBikeChannel]

Cool.

[@frostcold81]

Harm van de Bunte I get that knock sound too. I've had it since day one. do you know what it is?

[@harm97]

Ryan Frost,no not really,with the 38 keihin and the the rk head its gone now. Ik think it was compression/jetting problem..now the bike is a bit to strong for trails but good in the sand!

[@Whistlerzmother]

I would say the surface finish is like that from machining with a bullnose type cutter so he can machine multi surface angles. Looks pretty cool like that. Id be interested if there is any other reason why its been milled apposed to turning like most other inserts. A rough surface is good for mixing the fuel and air and helps atomise. Although with a 2t the case is where that all happens. Mmm thats going to have me thinking to hard. If you find out then let me know 🤘🏻nice video squire

[@TheOfficialKC]

Adam Grant they have a patent on it, though I don't know the number.

[@KurumaDesigns]

Great video! Looking forward to the review on the head!

[@Cooldibs]

Love your hat! Great brand and quality

[@coloradodirtbike5930]

That is very nice quality looking piece, is it similar to a cool head?

[@Mutiny-5050]

just ordered one. Kelsey had the same beta 300 as mine. looking forward to it to come next week. Super helpful and a pool of knowledge. gave a shot out to you and he was impressed with your following. maybe you can borrow his beta and get off that band wagon lol

[@DirtBikeChannel]

I'm going to review a Beta later this year.

[@Mutiny-5050]

Dirt Bike Channel nice. let me know if it falls through you can ride mine. just need to show me those killer trails

[@bignose140]

Quality video and info as usual. Keep it up! Love this channel

[@DirtBikeChannel]

Thanks for your support.

[@redeemedbob]

Please do a video on what you thought of the head, what difference it made to your performance. Thanks for all you do..love your channel!

[@DirtBikeChannel]

I need to ride it a few more times. Have only been able to put one ride on the bike and then I got snow :(

[@redeemedbob]

thanks. I ordered one anyway after talking with Kelsey at RK Tek 2. I am going to put it in tonight. Thanks again for your videos they are excellent!

[@harm97]

redeemedbob how does it run now?

[@redeemedbob]

I haven't ridden it yet. I'll let you know in a few days

[@redeemedbob]

I rode it tonight after I finished putting the head in. I love it! Lots of torque in the low end. Steady consistent power release. Substantially more powerful. I am really happy that I went with the RK Tek head.

[@ioanarusu6763]

Hello Dirt Bike Channel what difference is between this two pieces? The combustion chamber to the new piece is bigger or it's smaller? Thank you and have a nice day.

[@tmlpony]

Plz let us know how the new head performs,at low end threw midrange, thanks! your vids are very helpful.

[@stevehanson9917]

Great video. Did you use the same number plug? Any hotter ?

[@petrikurronen7175]

And those tyre shelfs are awesome! :)

[@DirtBikeChannel]

Thank you.

[@gsxrstyle]

Why do they have a money back guarantee on the 250 and 300 models but you didn’t mention 125s or 150s ...maybe a silly question but Im curious

[@DasChristoff]

can you tell me where you got the torque #s that you used on the head? I noticed you started at 14lbs and finished with 21lbs of torque. thank you for you're help and keep these videos coming!

[@calebnewton4347]

You should do a video on Christmas gift ideas for dirtbikers ;)

[@gmx0413]

I think he has🤔

[@blessedhellride2615]

hello kyle, just installed a rk tek head on my 300xc, ive been running premium fuel, do both trail and high speed riding, and plug looks very dark but is dry not oily, this observation was made BEFORE head install, what heat range should i move to with compression increase? thank you. mike

[@MrHiroboman]

What's the go with the crap machining? Everything with engine building is flow and smoothing things out. Any dyno sheets for this mod?

[@chriskosin472]

Is it worth getting one of these heads?? Is there a major difference over the stock head or is it subtle? Thank you for the response!

[@jasonsoutdoorsports8632]

Hey Kyle I'm getting the head for my bike do you think I should re jet my bike my jetting is spot on now

[@ArkansaDave1]

Love the graphics! Thanks for the video.

[@DirtBikeChannel]

Thanks Dave.

[@TheDirtbikeRider]

You have amazing videos !

[@DirtBikeChannel]

Thanks dude.

[@broncosfan-dk1uj]

I normally ride tight woods trails but I occasionally ride mx tracks because they are a lot closer to where I live. Out of all the two strokes you have ridden which one would in you opinion be best for me?

[@brettd8297]

With your experimenting over the years, any preference between RK Tek and the Slavens S3 high compression head, performance wise? Running 2019 300 XC, 1000ft elev.

[@dirtbikedudeministry6430]

Like the BCM hat! 👍

[@Goshary]

Cool! Looking forward to know how gas consumption has changed

[@DirtBikeChannel]

I don't know if there will be any noticeable difference there.

[@kinglouis6974]

Surely just skimming your head is the same ?? I’ve got a kdx220, I’m gonna rebuild the top end and skimming the head is on the list of things to do

[@seanjohnston848]

Any noticeable differences so far? Power, fuel economy etc?

[@kevinstearns4198]

i think its a waste i would shave the head and call it a day theres a video on that i never did it.

[@woodsrider117]

You didn't try one though did you..

[@kevinstearns4198]

wouldnt bother porting shave the head pipe silencer other performance mods you can do.

[@kevinstearns4198]

yes i didnt notice a difference.

[@SmallShopConcepts]

that's a pretty trick head! sounds like you are enjoying some benefits from it so far. I'm sure you're making us wait for the review video for specifics, but I am curious about the areas of the rpm range it changed most. I recently purchased a YZ250X and like you found the low end was a little lacking. wondering if a head like this might be a solution?

[@DirtBikeChannel]

Low end and mid range were the gains for me. It's almost scary now :)

[@TheDarios1988]

Are all heads torqued to 21 ft lbs ? I want to open up my head on my 2011 Husqvarna wr150 and check the cylinder head. Can’t find any torque rating on my bike

[@JMcP231992]

Good install! Will you be doing a review on this fully at some point in the future? Not much info online but would be really keen to hear back

[@DirtBikeChannel]

yes, I plan on reviewing it when I get some more time on the bike.

[@fantaseditings3017]

Can you tell me what's better to increase performance and engine reactivity between S3, VHM, HTM etc etc...

[@sleder22]

is the a review on the preformance?

[@turbo800rev]

Hey Kyle, I'm also from Utah (Logan) and ride the same altitude. I'm curious what grade fuel you specified and what ratio Kelsey engraved on the dome insert? Didn't see that mentioned in the video. I got mine installed last night on my '20 Husqvarna TE300i. Thx, Shaun.

[@Mutiny-5050]

Great review. I looked them up and they make one for the Beta. Might have to upgrade. Would love to see the riding footage. Did it make a big difference?

[@DirtBikeChannel]

Yes.

[@Nate2k14]

awesome video!

[@sidecarbod1441]

It is truly amazing that the bloke that is making these heads thinks that it is a waste of money to change the carb or the pipe and you would be better off buying one of his heads! Doh!

[@DirtBikeChannel]

He doesn't only make these heads. He has a 2 stroke performance shop and does all kinds of mods. He's a smart guy. trust me.

[@howarddavisIII]

hey kyle,another great video...! do you know if they make this design head for a 2000 exc 300? also when do you tentatively expect to make a video of the advancements of this head?

[@DirtBikeChannel]

You'd need to call them and ask. I have the link in video description. I don't know how long it will be before I do a results video on this. I have only ridden it once and it's snowing now :( I would like to get a couple more rides on it before giving a full opinion.

[@DasChristoff]

Hey Kyle. great video. I have the same bike. would you recommend this over a slavens mule? seems like more thought went into this product. im anxious to hear how it performs.

[@DirtBikeChannel]

I think I like this head more than the other. I'm not sure we need more power on these bikes, but this is a well made product that does a good job.

[@mikerasmussen7367]

What about bleeding the air out of the coolant at the compression head? Small bolt for bleeding?

[@DETAILDENNIS]

I want to give a shout out for the great down to earth reviews and opinions. With that said comes a question. You have reviewed two products the Slavens S3 head. And the RK Tek . Both seem a good choice but the RK seams to have slight advantages. In your specific general riding areas , elevations, and abilities .... what would be your choice head on your 300 Ktm? I realize your 250 May have a different opinion. I am considering one of these on my 2016 Husky TE300 Your impute would be helpful !

[@poorwhiteboy6521]

What should compression be with stock head and with rk tek ? I just installed a rk tek on my 2018 300xc only got 180 psi guessing I do for a new top end ?

[@ynot6369]

is there a full review of this head coming soon .

[@chuffingstuff]

I’ve fitted a lectron carbs to my ktm exc 300 2017 I’m also running a RK-tek performance head and a vforce 4 reed valve. The Bike isn’t too good. It’s seams to be lean, over running when shutting off and sounds like some knocking. I’ve tried to adjust the air mixture screw and got it a bit better. I know you can adjust the metering rod but I’ve not tried that yet. The bike was running ok on the original head but want to try and get the performance head to work with your carb. I live in the uk and ride under 1000 metres altitude. Have you any settings or advice on the matter.

[@jimineutron259]

That last small bolt was to bleed the air out so the coolant area doesn't have air pockets. Get a nice air pocket and you'll overheat.

[@harisdanela290]

What torque wrench were you using in the video? Cheers👍

[@wrenchg3954]

I gotta point out that he has seriously got his carb DIALED! I mean God damn the piston and combustion chamber is beautiful!

[@DirtBikeChannel]

Thanks Richard.

[@wrenchg3954]

Dirt Bike Channel. That carb tune is NUTTY! God i really got to work on getting my bike dialed. I've never had any problems getting an engine tuned well but i didn't know that is was even possible to get it that dialed in. And by the way love the channel. I really like your approach to many of the topics that you touch on. Can't wait to see what i can learn next! Thanks

[@chrisnielsen5287]

The thing looks sick

[@DirtBikeChannel]

This bike has scary power now.

[@krazed0451]

+Dirt Bike Channel Rough eta on a head review (giggle)? Bike looks great, who did your graphics?

[@DirtBikeChannel]

Going to be a bit. Need to ride it more for a full review.

[@wojciech8881]

Could you share vid with review? It will be very helpful!

[@ynot6369]

just ordered mine.Rk Tek wanted to know how I heard of themwhen I called , made sure to let them know "Kyle from dirtbike Chanel" can't wait to get mine .

[@DirtBikeChannel]

Thanks Jaime.

[@ynot6369]

was wondering if you run gas from the pump ?

[@riptripper1627]

whats best slavens or this?

[@DonHartSC]

One more @superdavemich. Interested to find out if you saw an increase is fuel economy and performance. Great job on your channel Kyle, love your perspective as a regular guy who loves to ride. I'm considering the RK Tech or Slavens S3 for my Husqvarna TX300 (Lectron Carb installed). Video comparison between two?

[@superdavemich]

DON HART ADDED RK TEK HEAD W/air box mods tons of power smooth have not been able to ride normal trails michigan winter to see mpg seems good on short runs

[@superdavemich]

don hart as per rk tek advertising bump up a gear no problem

[@adamteng343]

Thanks for sharing this video is awesome I learn a lot from you. Thanks!

[@DirtBikeChannel]

Thanks for watching.

[@jasonsoutdoorsports8632]

How long did it take you to get your head in? I've ordered the same one 6 weeks ago and still have not received it

[@davidruth1]

Hey, have you had any detonation problems with your RK Tech HV Lectron carb combo. I have the same head as you on my 17 with this combo and cant get the detonation tuned out. I am also running Saber oil, premium pump gas, which I think you are as well.

[@KTM753]

David , I am struggling with detonation on stock head milled 0.020". I am running 50/50 mix of 91 and 110. Still have detonation. Did you have it before with your stock head? or just now with new head?

[@johnlittle4508]

Kyle. Did you have to mess with your jetting at all?? Or are you going to leave it?? Love the channel

[@DirtBikeChannel]

No, I didn't touch my carb after doing this. I think this would solve some of the jetting issues guys are having though.

[@chrispederson4157]

Where did you get that Ktm 990 clock on the wall. Looks like my 990 guages.

[@steveyurko2581]

Hey Kyle - just subscribed and signed up for monthly donation too. Awesome videos, big help as tinker around with new '17 sixdays 300 xc-w. Having a blast on this bike on trails. This RKTek2 working well for you still? Getting the improved gas range they advertise? Thanks much

[@DirtBikeChannel]

yes, the RK Tek head is pretty cool. Thanks for all your support. Hit me up on patreon with any questions, I don't see most of the stuff that gets posted to KZbin.

[@moshpitcircles6345]

Your graphics kit looks nice!

[@DirtBikeChannel]

Thank you.

[@jianoconnor8414]

absolutely Fresh "O"rings is better. Also apply antiseize to the bolt threads :)

[@user-zx1ir7jt4c]

"I'm going to twerk all these bolts down" lol

[@ethanperalta9346]

Hey Kyle I'm a new subscriber and love your videos. I wanted to know where you ride mainly. Thanks!

[@DirtBikeChannel]

Utah for the most part.

[@jasonwier9802]

Love the videos!! How has the head performed?

[@DirtBikeChannel]

Great. Only been able to ride it once since installing, but it ran like a champ.

[@jasonwier9802]

Dirt Bike Channel Can't wait to see a review! I just picked up a 17 300 and am considering this mod.

[@superdavemich]

Kyle any more info on how this worked for you??

[@snakeriverroofing7445]

I have the same bike and just ordered this head and let them know I found it from dirt bike channel. my altitude is from 2800 to 6000 feet. I really would like to know what jetting you are running, as mine is not working well at all which sucks on a brand new bike. thanks kyle

[@superdavemich]

did you have trouble before or after you put rk tek head on??

[@snakeriverroofing7445]

stock head. I have not received my head yet

[@superdavemich]

air box mod helped mine alot

[@redeemedbob]

I put the RK tek on my 17' 300. It was a little mushy in the bottom end then I adjusted the carb to richen it a bit and it was magic. tons of power at my fingertips.

[@snakeriverroofing7445]

redeemedbob what jetting and elevation are you running

[@mikeanderson5100]

What oil are you running in your gas? Pump gas or are you mixing race gas? Thx

[@DirtBikeChannel]

Amsoil Saber. Pump gas.

[@Broadysword]

Hey mate. Quick question. I seem to remember you mentioning on a previous video that you have an item you use in your car to strengthen your clutch finger. I like to slip the clutch with 1 finger not 2 but I've not got the strength to keep doing that for very long. Can you let me know what device this is and were I can get one? Cheers!

[@DirtBikeChannel]

That thing gave me tennis elbow! I need to issue a PSA against it.

[@Broadysword]

Dirt Bike Channel oh alright haha. I'll just keep practising! 😊

[@z28fast1]

Is re-jetting required? Thanks

[@Bloodfang152]

z28fast1 Pretty much yeah

[@michaelbielaski3543]

I might guess that the design is to maybe add cylinder volume and improve combustion as well as cooling...

[@DirtBikeChannel]

The head was pretty scary on the power side :)

[@aussiebriza6170]

Can you do that to the ktm tpi bike and can you do to in prove performance on the tpi bikes a video talking about it would great

[@zegast]

This episode i liked :)

[@emmettcampbell4293]

Do they make these for the 2004 KTM 300EXC? My dad has one and he loves that bike and I wanted to get it for him for Christmas

[@DirtBikeChannel]

I don't know. I put the link in the description. You should give them a call.

[@kenfarnsworth5239]

MoparOrNoCar 82 you could buy him a new bike instead .lol

[@emmettcampbell4293]

Ken Farnsworth I'm only 14 I would definitely if I could

[@sethcooney602]

I clicked on the link and the website has been removed!!! Is there anywhere else I can get a custom head?

[@maggieconnors7241]

You using amsoil for premix?

[@subrbanwater822]

Hey dirtbike channel do you think he would or they would do my 1990 kx 250 if not you know who would thanks man

[@JAAK_49]

its definitely a different looking head!!
