Thank You for supporting! I appreciate you!
NEXT VIDEO coming up in the the next week? Steve will discuss the difference between the RX1 Yamaha and the APEX Yamaha Engines! Stay Tuned!
what year engine are you talking about?
The camshaft drive chain tensioner is a failure point on Yamaha engines , the coil spring has been known to break and release tension on the cam chain. This results in a catastrophic engine failure as valves hit the piston. The cure is quite simple , a longer 6 mm bolt that pushes on the end of the cam chain adjustment screw to stop it backing off in the event of a spring breaking. A lock nut on the longer bolt holds it in the desired tension. Yamaha YZ250F & YZ450F and WR models all use the same design cam chain tensioner , my personal WR250F had the same failure but fortunately I noticed it before it caused major damage. King regards Adam Troy
Sounds good to me. Thanks for sharing. I have shared this with Edge Performance maybe they or Steve can reply? Thank you for watching!
It's an issue with single cylinder engines but not 4 cylinder. 4 cylinder engines have smoother cam operation. A single cylinder you have fluctuation in the stress on the cam chain and tensioner.
Steve is such a legend, very interesting to hear the story about him overcoming the motion problems! good content Brian!
Thank You very much for your kind words and support! I see YOU just got a new aircraft yourself yes? Fun times ahead! Thank You for watching!
It's surprising to hear how many professional aerobatic pilots had motion sickness on their first airplane flight as well. Kudos to Steve for pushing through!
Experimental Aircraft Channel I did, thank you man!!
Ken is so close ✈️❤️ he told me he admires you. Glad to get to know you
Steve Henry is one of the guys who helped me get the "aviation bug". Instant subscription for the quality interview.
I watched this video several months ago, but didn't make a comment....I am amazed at the versatility of the Yamaha engine.
" ... headache for 3 years ... " All of a sudden I feel incredibly fortunate. My dad and uncles used to throw us around like acrobatic toys while we were still in diapers. When my uncle bought a PA-18-125 back in 1951, aunt Gracie was the first passenger, I was the second. Over 70 years of zipping, spinning and flying around, don't recall ever not enjoying a single minute of it!
Sorry to hear this. Haha! :-) Thank You for watching!
It’s bad enough I envy his planes... now I envy his shop too
These engines are extremely well made. I know of some Yamaha apex sleds in eastern canada that have 60,000 plus kms on them and the engine has never been opened.
Good to know. I think the whole world will be watching this engine soon! Thank you for watching!
Good to see Steve again. Nice interview.
Thank you! Thanks for watching!
Love it!
Great guy with passion for what he is doing,love his workshop.
More on the installed engine, and gear reduction please. Great vid.
Oh.... there will be much more coming out on the Yamaha Engines soon. Outside of Steve and his shop too. Just wait! :-) Thanks for watching!
Loved this interview of a really awesome guy
200hrs on a kolb. Thats awesome. My kit is an "ultralight" what a good vid. And dang musta been fun hangin with Steve.
It was GREAT hanging out with Steve in his Hangar and then in his Shop! I wish I could have went flying to experience the nearly VTOL climb performance! Maybe NEXT TIME. Thank You for watching!
I’ll say it again Bryan, another great informative video. You kept him engaged without having to break the flow of the conversation and video. It’s a smart person that knows their limitations and knows how to surround themselves with the right people to be successful. Kudos to Steve and his success and to you for brining us another informative segment. Please both of you keep up your work in experimental aviation because this is how real advances are made and how the public finds out them; from the people that are living them!
Hey! Thank You! I really appreciate the support! There is one more coming after this one discussing the differences in the RX1 and Apex. Thanks for watching!
Looking forward to next one!
There is one more coming after this one discussing the differences in the RX1 and Apex. Thank you for watching and supporting here!
300HP!! 👍👍 MAN, that must be a blast!! I'd be able to launch a good sized aircraft out of my backyard with that kind of power! 😎
If I ever get or build one of these aircraft, I'm sold on the Yamaha. I've worked on that style engine for 20 years now. The fuel injection is new to me, but it can't be any worse than modern automobiles.
Looking forward to your next vid on these engines! 👍🍻
There is one more coming after this one discussing the differences in the RX1 and Apex. Thank You for taking to time to watch and also engage here! I appreciate you!
@@ExperimentalAircraftChannel - Thanks, Bryan! I'll be watching for that one - sounds great! Although those engines look similar to their motorcycle counterparts, I'm not familiar with those 2 engines at all. Curious as to what I will learn about them. THANKS for your efforts here! 👍🍻
Great video! Cool to see what got other people into aviation.
Thank you. And Thank you for supporting our channel! There is one more coming after this one discussing the differences in the RX1 and Apex.
Great interview, well done!!!
Thank You very much! Thanks for watching!
That's a proper workshop where things are made.
Great job Bryan! Steve Henry is such a great guy, I’m stoked to see him bringing in Ken’s motor mount jigs too I think that’s going to make a lot more Yamahas fly.
YES! And Thank You for the opportunity to see you and your new KitFox! Looking forward to your adventures!
really cool video. I really like to hear about your subjects, their lives and how they got into kit building and just aircraft in general. This vid did the whole deal. Mr. Henry is a really interesting guy and seems really down to earth. It's kinda neat to me that another crane operator is a pilot also. I'm betting it is a somewhat rare combination. Keep them comin!
Thank you for the encouragement. I really appreciate you. More to come for sure. One more with Steve this weekend and then more on the Yamaha in the coming months. Thanks for watching!
Seems like both you and Steve enjoy swapping stories. I heartily approve! You are making this channel simply outstanding!
I love listening to people's stories and seeing what they are doing in their workshops/hangars/garages! Thank YOU..... for showing up to watch!
I'll just go ahead and like this before it even starts! :D
oh, and that's definitely a "first" lol
you’re supposed to comment “first”.... that’s what all the cool junkies do...
Yamaha makes great engines, and since at least the 60's has made all of Toyota/Lexus high performance cylinder heads. Would love something like this in a Sonex
Really interesting and informative video. Love the format. Great guest, cool backdrop, interesting subject matter. Looking forward to the next video!
There is one more coming after this one discussing the differences in the RX1 and Apex. Thank You for your support. I really appreciate you!
Suggestion: look at cams to change the valve duration opening. These engines are designed to rev out to pull up hills. Short stroke, high rev. They can be calmed down by changing the lobes so they make more torque, less vibration. I would suggest Crower Cams as a start.
Love your videos with Steve Henry! But I really like all your videos...
Irv Thank you! It is really good to hear! Thanks for watching!
First time I've heard Dean Wilson's name in years! I built Avid Flyer #79 in 1984-85...got interviewed by Good Morning America at Oshkosh that year!
Really? How cool is that??? Thank you for watching and strolling memory lane with us!
Another really good video. I love the content you choose. Keep up the good work!
Hey JP White! Back again! Thank you for your support! I really appreciate it!
Also I am really intrigued by the Apex turbo Yamaha. Really cool stuff. I am an old hot rodder that has gotten into flying as of late so the engine stuff is really interesting , as the old typical Lycoming, Continental stuff is just such old tech......Nice to see some fresh things and ideas hitting the table!
Right.... THIS....truly is HOT ROD Aviation!
Steve is a legend.
I ran this engine (non turbo) in a 2007 Apex and it was amazing! The sled was really heavy but the motor was special. Considering a Kitfox and would like to know more about this motor with turbo and how the turbo maps out, how much boost is used, and how long boost can be applied before having to back off.
Wish my wife would be the same she is terrified ill end up my name in the news. She knows I love flying I worry my head won't be where it needs to be while training thinking that the entire time she is worried sick back home about me. The Yamaha 5 valve engine has amazing power. I remember way back in the 90's when 4 strokes started in motocross up until then most people considered 4 strokes never have the power a 2 stroke had until the Yamaha 5 valve engine came out.
Great content! Steve overcame three years of constant headaches for the love of flying. How many would’ve stuck it out that long?
Doubt I could .
Pee Wee tires,that cracked me up.
Not to mention the tire
Hah! Me too! I don't know if you could hear me in the background chuckling! Thanks for watching!
Steve seems to prefer the highlander over the Super stol... Must be some advantage in a fabric wing for what he does. Lighter I guess.
He is running extremely lite! In fact he is using Oratex that comes already in color. Thank you for watching and supporting here!
Not long enough!!
HAh! Thanks! Thank you for watching at least all of that! :p
Where do you find cool people like that?(I love your channel)
We LIVE on Social Media and engage with our Community! Aviation is truly a great family of people. You don't have to look hard or far to find such amazing people! :-) Thanks for your support!
Wow.his shop is almost as messy as mine. He as learned to work in organized chaos. I still got a way to go yet.
Hah! Not as bad as mine at this moment! :-) Thank You for watching!
I'll take a Yamaha mount and engine for my Sonex! Even though I finally got that VW running...
That would be a crazy cool mixture of airframe and engine. Even in the stock form of 150HP would be amazing! Let me know if you do that PLEASE! Thank You for watching!
@@ExperimentalAircraftChannel Hahaha, yea it would! Even the Jab only has 120hp, I think 150 would be plenty. Add some Allen wing tips and it'd be a whole new plane.
I've got to get it flying again first, then we'll see what happens. Definitely worth looking in to, might be a next winter project.
What sort of numbers are we talking for TBO, reliability? What octane/aki? , gearbox ratio/ prop rpm? There's a need for reliable 250-300 affordable hp on mogas all over the world
Good questions. Good Questions. I don't think they have actually set a TBO yet. I believe the normally aspirated can run on pump gas (not turbo) and the gearbox is somewhere in the 4-4.5 to 1 ration I think. I will have more info on the Yamaha coming soon. All the details. Thank you for watching!
Have you done any :Yamaha engines in PPCs?
Steve, was your headaches due to altitude sickness?
For those who have it (my dad and oldest brother, and hunting budy have it) increasing your Nitric Oxide intake could solve that problem. I fly a T-Bird II and want to jump up to the Highlander!
I believe it was due to the "motion." I have a similar problem during the first 10hrs of my flight training. I was always getting sick. My instructor didn't think I was going to be able to flight train. I worked through it by taking shorter flights and building up to longer flights. Thank you for watching and supporting here!
I love the intro/outtro muisc, can you please tell where to find it on the web and listen to it. THX
"Out the Back" by Biddy Sullivan. It was found on Epidemic Sound (Where I get all of my music). Thank You for watching!
I would love to know what oil he uses on his EPEX's. I Just bought an Apex and will eventually put it in a Highlander. I would just like to know what Steve puts in his!
To finish what I started saying the tire hanging on the wall above the during the interview.
WOW YOU LEFT ME HANGING.... Are you making these motors available and how much would they be ? I am 50 /50 living in Canada and Philippines and have great access to the Yamaha sleds.
Would you sell a kit to build up a Yamaha motor with your gearbox headers etc ? Hope to hear from Steve.
Check Steve's website at wildwestaircraft.com
Hey! Sorry.... there are different pricing depending on what you are looking for. The base "stock" Yamaha goes for in the low $20k range from Steve. Check out Steve's site of Edge Performance. Thank You for watching!
What do you do to the fuselage frame to make able to handle so much more thrust?
I have asked this over "other" aircraft manufacturers recently myself. Being the load is so spread out across the airframe into the longerons most say it isn't an issue. The issue is the aircraft now being VERY capable of going well beyond the VNE in straight and level flight etc etc. Thank you for watching and engaging here. I appreciate you!
Experimental Aircraft Channel most say it isn’t an issue but do they really know? Has a competent person done analysis? If it isn’t an issue then the stock airframes might be way over built. Or maximum engine mount and the longeron loads are driven by something other than thrust forces and moments. But to determine that takes some detailed work by a qualified engineer, not some guy looking at it and pronouncing “ah, it’s fine, hasn’t fallen off yet”! One always wonders how much real knowledge is behind these mods.
I want to see someone put a fuel injected vtwin Harley engine on a plane
I bet Steve was a Street racer back in the day.
I think Steve raced EVERYTHING and ANYTHING back in the day! Thank you for watching!
Turbo disqualifys lt in sport though right
Weight is_______ ?
Hmmmmmm. That is a good question. Does it state "Normally Aspirated" or just simply not a "High Performace." (Fixed pitch, fixed landing gear) etc. The weight I saw on the turbo that was about to be installed (with everything thrown on it needed to run) was right at 199lbs. Thanks for watching!
Would be interesting see this engine in a high performance experimental like a lancair
Would love to hear more on what’s been done to upgrade the engine internals to put that kind of power out reliably
There is much more to come on the Yamaha Engines both STOCK form and High HP. Thanks for watching... stay tuned!
Helo sir I made ultralight aircraft home made by using bike engine KTM390 which is produced 10000 rpm it is successful??
Why snowmobile engines in particular? Why not an air cooled motorcycle engine. They make decent hp and are light weight. Just curious, not critical.
Luke P
Luke, when I seen the price of a stock engine from Steve, I agree with you, but only if the Yamaha engine price is a lot more stand alone like a Honda would come. I can Tig tanks and headers and I would probably buy a heavily tested ratio prop drive. I Love Sonex and I would love to see it in a Sonex. Be Blessed
Snowmobile engines don’t have an attached transmission . That engine was used on the 1st gen Yamaha fz1 and r1 motorcycles . Snowmobile version of that engine is probably about 40 lbs lighter . On motorcycles those engines run thousands of miles with just oil changes .
I love your content so far but have a constructive comment: there's kind of a "standard" in audio volume (for broadcast TV at least) and it's -7 VU. Nothing should go over that level, not the swooshes not the crazy knocks or the incidental muzak. Your videos are way too high overall, and it's a big PITA to have to rush and hit the down volume every time you want to watch one. On the other hand, man, please, don't use the obnoxious sound FX noises anymore! Super loud Swooshes and knocks. They're REALLY annoying. Thanks for your work. In all other aspects, it's really good.
Drag race STOL is a foolish way to to race.... race what. Power WINS
Really? like regular car type drag racing wins on power foolish? Well, they gotta whoa the airplanes down on the clock and turn around too, ya know? cars don't stop on the clock. They just go wide open A to B on the clock
it looks like a crotch rocket engine.
"So that's when I started doing that", ""he mentioned him"", good thing the U.S. government took the lead out of the paint in 1978, too late for Steve Harvey, though.
