Everyone I've seen running with these RK Heads is more than happy with the performance, no matter what size engine . 👍
I’m stoked
They say with RKTEK head provides torque at lower RPM’s for the big bore 2T. More usable power at the right rpm for lugging, hill climbs and riding a gear higher. Sounds intriguing
Just saw the end of the video regarding 300TPI RKTek head. Look forward to that video and your impressions of the 125 👊🏼
It should be really good
Cool video!
RK Tek is cool as they will give you exactly what spec you want. A fast guy friend raised his 300's cylinder a tad to increase port height via base gaskets for a little more top end RPM, he also runs race fuel. RK Tek created a head just for his bike's specs, and man, it rips.
Gotta run a programmable fan and a small Trail Tech digital temp gauge mounted to the center of the bars on 4Ts with Evans - an inattentive rider can melt the hoses off otherwise. The great thing about Evans is it does not puke past the cap, so the level never drops. Evans also does not corrode the system. Have run Evans in my '10 Husaberg FE 450 since it was new, the cooling system still looks like new inside. I suspect Evans is kinder to water pump seals over the long haul as well.
I love your help and encouragement Morgan! We came out to Montrose to ride! Just because you asked us to go ride our Dirt Bikes!!!!!
Yes!!!
Glad I'm not the only one who thinks that way about evans. I'd rather see the steam and smell it before I damage something.
Yep
Man, the wee KTM is getting all kinds of love! 👍👍
I know. I’m loving it.
I run evans in my 2007 KTM 450xc RFS motor, I’ve ran tight Oregon single track in the summer and never saw above 200 but it’s good to know that it could possibly get too hot without boiling in a four stroke. Love the content 🤘🤘
Thanks man. Yeah it’s more in the hard enduro kind of stuff and in the newer bikes. The new 4T’s run hot because of how tight all the tolerances are and how much horsepower they make. Those RFS motors don’t make the temps the new ones do.
Love your videos. Very helpful. Hope you make some more!
Thanks. We are making tons. Make sure you subscribe
@@highlandcycles subbed!
@@rvh77 thanks
Brother you’re making me spend too much money! Remember I have TWO of these so every time you post new content on this ripper I’m reaching for my wallet! 😅
🤣😂🤣
What was the compression difference between the stock and RK?
Not sure what the actual number is but I know I will have to run 50/50 race gas at sea level
Remind me again- what 2 stroke oil and what ratio? I heard you say it but can’t remember, riding a 17’ YZ250X- thanks man
I run 50:1 and motorex
Hey sir, just got this head and installed it on my 22 125xc.. any recommendations on jetting my carb. Im new to it, but I just bought a JD kit and trying to figure out where to start with this head insert.
I would go up 2 sizes from what JD recommends to start
@@highlandcycles
JD kit recommends 460 main jet. But with this head insert, where should I go from that in regards to the main jet / clip position? Thanks Morgan. I appreciate your help !
@@austinmcguire5431 480 and #3
@@highlandcycles thank you brother. cheers.
Haha, I’ve told you that’s gonna be good mod for the bike! 🥲
We will see for sure. Just didn’t want to buy one. But Kelsey was so generous so it makes it a no brainer
@@highlandcycles it is really wonderful that there are so many generous companies to help you. keep it up!
What octane fuel were you running, and did you change or adjust with this head insert?
91 and no. We live at 6K so no need for race gas with this insert
Awesome thanks. Do you see any need for me to do anything different at 1k-2k elevation?
Thanks man
@@austinmcguire5431 not if you get the head for that elevation
@@highlandcycles ahh make sense haha. Thank you.
I have a 2019 xcw 150. Would the rk tek insert make a noticeable difference on the bottom ? Is it necessary to change jetting if you do the insert?
Yes it would make a big difference to the bottom end power delivery and yeah. You need to go up on the jet sizes but I seem to only need change the main jet.
Do you have a video up on fuel injection cleaning ?
I don’t yet
Soon I hope you put up a lot of good information.
Any need for higher octane for this modification.
Not up here in Colorado. Might have to mix 50/50 with race gas at sea level
No you chose what octane you want to run and they mill it for that compression ratio based on the octane you run, you can tell them that your going to run 87 and they’ll set it for 87
