Harry Evans 2stroke is the way to go I fucken hate working on 4 their are too many problems fuck the government hope trump can change the pollution laws
I loved these bikes. Used to buy them off owners who were afraid of them for $600-$1000 in the late 80s early 90s. Kx 500 / Rm 500 /Yz 490 /IT 465/ CR 480 were my collection. Had to sell them when I left the country though. Now its big bore chainsaws.
my dad had a honda cr 500 for 10+ years but sold it about 20 years ago, it has always been my dream to give him back this bike he was in love for the past 3 decades...
Amazing build !I'm not surprised at all at those numbers from a ported ,bored ,and stroked HONDA CR500R if that is the case with your absolutely awesome showpiece ! You turned her from the ugly witch into a beastly beauty !Tons of man hours of labor indeed ! Magnificent can't say enough ! Long live the BIG BORE 2STROKES !!!
No, it' not stroked, i use a totally different top end kit and the cylinder is bolted to the adaptor plate and the plate is bolted to the stock stud holes at the front of the engine block. You won't get these power numbers from a ported 500 cylinder. Thanks for the comments😊!
+supermotardmario i believe those hp numbers when i see the dyno runs. Everybody talks about how much power they have but where are all the dyno sheets? And what fuel was used? It's not realistic to think that a motocross cylinder at 500 cc running on pump fuel would give almost the same power output as a 550cc racing cylinder designed to give maximum power. This is the latest design in twostroke technology, a CR500 was never desigbed for high power from the beginning and the design is 30 years old.
Off Road Domination I know this is an old comment but could you enlighten me about your comment? would it seize due to lack of lubrication from letting off or what?
yes on a 2 stroke if you engine brake (let off the gas and dont pull in the clutch) the engine will spin at high rpm with only a small amount of fuel since a 2 stroke gets its lubrication from the premix oil in the gas when there is little fuel with high rpms it causes heat then friction will build up and the engine will eventually sieze
Off Road Domination How would you slow down with engine braking, if your holding in the clutch? Wouldn't that be coasting, since your holding in the clutch.
You can not get an accurate reading from the dyno with motocross tyres because of slip. I had problems with wheelspin with the road tire too but we glued it and cleaned it with thinner, then it hooked up.
Sorry, you can't buy them. They are designed by me specifically for this bike and tailormade by a company here in Sweden and noone else than me can order them.
Rode one back in the 70s on Knoblies down the local field. No fear as my road bike was Kawasaki 500 H1 and I thought that was mad as a box of frogs....nothing compared to CR500......note to self 2nd is for starting off 1st is for coming off!
90+ HP !!! :) This must be absolutely crazy to ride, I guess it has a narrow power band? This is the first dyno of 2 stroke I have seen where they had the sense to pull the clutch and not let it engine break to a slow self destruction.
Dont nit pick this guy over 5-7 hp max,,,,,,this thing is a hand built monster,,,,,,Obviously.... Nice build man,,,, it looks like quite an amount of R&D went into this rocket,,,,,a stock CR 5z a handful at times,,,,,,,, I love her big respect on that project!!!!!
I remember when they raced these bikes in SuperCross, I think it was Chuck Sun who raced for Honda.So a factory preped 500 yeah. Great job.I just missed a KX 500 on craigslist. ..
It depends on what year of bike we are talking about. The Maicos are very powerful for a motocross bike and the Hondas were detuned during the years for better Engine character.
Nice bike, its cool to see someone actually tuning a bike and not just swapping regular aftermarket parts then saying "you can only get +5hp with all of this" 2-strokes are all about the timing. You might say 30hp is the max for 125cc but there are 55hp 125cc motogp bikes that make that power at higher revs because of the tune. Sure you could tune a 125cc motocrosser to 55hp if you really wanted to. Aftermarket pipes only improve on the stock design, not to shift the rpm higher e.g more power.
+Johnny Lehti Ryger Engine is a new 2-stroke designed and made by "Harry Ryger" It recently got approved by FIA, it's made for 125cc Karting. There aren't much info out of the engine but I can guarantee it's 100% legit. I have the patent papers and images. I can send you some images of the engine's components on Facebook or somewhere. The way how the engine revs 30000rpm is that the piston rings don't touch the piston. Yes, they don't touch the piston. ESE's works engine tuner thread on the Kiwibiker forums has a lot of information/speculations of this engine and one of the engine creator/tuner/developer also writes occasionally on there.
with that power to weight ratio you are blowing away street bikes in the 1000cc range with ease from zero to 60 and maybe even 1/4 mile. That's a dangerous bike lol
Nope. The latest 1000cc bikes have around 200 to 205 horsepower, if you exclude Honda with its 186. And only weigh about 200kg while this kawasaki weighs 105, it's allot lighter yes, but the power to weight ratio still favors the street bikes. Not to mention they have better, faster gearing, launch control and such. And in straight line performance, horsepower counts abit more than light weight.
@@seanm6311 Assuming the front end stays down. 60' suffers bad as that front goes higher... short of that I believe the lighter bike would have a fighting chance. But, you never know until win lights flash on the big end and time slips are handed out....you just almost never know.
@@seanm6311 That is true, but remember light bikes also struggle to keep their front end down and be controllable at launch. Those modern litre bikes have launch control and traction control, all sorts of goodies that make them take off at nearly the speed of AWD super cars
@@dean8067 Yeah I agree, (now), you're right. The 550 CR would mono too much. Even if it had a long swingarm and lowered suspension, it wouldn't match launch control of a big bore road bike. No way.
If you're pussy enough to have to ask if it's legal, just go get a 250 4 stroke with training wheels and be done... what are they gonna do? Gimme a ticket? Good fuckin luck catching my ass with 90 horses...
That is so awesome, just bbqn and checking out the super moon, it's killer and needless to say I would love to have that bike...lol. good luck to u sir.
Chain is perfect. Once the bike is run on the road and the rear suspension is compressed and the bike is Wheeling or Close to the slack is perfect. Better a bit loose than too tight.
But doesn't a bit loose still effect chain life? Feel's like a double edged sword cant be to tight or loose. But trying to find that sweet spot is hard sometimes.
There is measurements to go for. it all depends on how much the chain stretches when the swingarm angle is decreased. When the swingarm is horisontal you want a slack of about 10mm.
Soft suspension of a cross setup has a lot of travel when you sit on it with 90kg of body weight +maybe up to 10kg riding gear. So the chain tightens when you sit on it
thats 1 mean bike you got there..i have a yamaha blaster with a built yz250 engine swap..i cant imagine how a built 500cc 2 stroke would feel :) nice bike man
Faaaaaaaaarrrrrk. That thing is beautiful. I bet she goes like a bat outta hell. I’ve vot a 83 YZ 490 K that was built for the Finke desert race here in Australia. The motor had a lot of port work done and the Wiseco piston didnt look anything like a stocker. It also has a Bing carby on her, the crank pin was relocated or they used another crankshaft to up the capacity to about 510 cc. All the work ive just told was done by the previous owner and im just saying what i remember when i bought it 33 years ago. I also remember him telling me how hard it was or time consuming it was balancing the motor to perfection. It did run very smooth compared to a stock 490. He caimed it made 84 or 85 hp at the motor. It is or was an absolute monster to ride and was geared to do 140-150 mph. It had no bottom end power at all but when it hit powerband it hit like a yz 80. Nothing inbetween. Top gear power starts were no prob but as a motorcross motor it woulve been useless. It was designed to go flat out at all times. The biggest fault with it was if it ever dully hooked up at vertually any speed it would just stand up on its back wheel. It also sat very highwith over 14 inches of travel at the back and nearly 14 at the front with a set of Marzorchi forks. It also had the rake of the forks decreased to help stop it tank slapping. It still had a tendency to start tankslapping but i found the best way out of it was to just turn the throttle a bit more and it would wheelie. It gave the smoothest ride iv ever had on a moto x bike. It was just plain simply plush. It you hit a rock or ledge at 70 mph youd barely feel it thru the bars, the sMe with the back end. Annnnnd it didnt have the kick back like all the YZs had of that era. Very, very smooth.. Nearly every single one of my mates who rode it, got spat off. Most of em it got them exiting the first corner they went around. They’d get three quarts around give it a bit of throttle, nothing much would happen then bang. The back wheel would go from 15 mph to 70 mph ai a matter of milliseconds and it would iether flip em off sideways or just wheelie and they coulnt hang on. Compared to my 83 CR 480 it made the big torquey 480 feel like a slug. It even makes my KXf 450 feel like a gutless heap. There is such a thing as too much power or a better way to put it, too much too soon.
Thanks! Ok, well, i Think you should be glad if you got over 65 hp on a heavily ported YZ 490. It is very common that people "estimate" their powernumbers on these bikes because they are fast and wheelie in almost every gear. They are light and the higher the suspension is the worse they are when it comes to acceleration because they wheelie so easy, especially when the suspension is set up for dirt riding. But as long as you enjoy alla is good :)!
91 horse freak nasty bro, shes a beast hard to tame throttle open in them gears! The adrenaline I could feel tho please let me ride it one time hahah:)
*92 fucking horsepower you have created a monster a beast think of the weight of a bike with 92 hp omfg*

Just perfect! It won't see much dirt though :). Mostly ice and tarmac !
+Edgar Costa Don't think it will touch dirt with street tires...
+George Badass he put those in there mainly because knobbies slip on the Dyno
+Cobee Rice Well i don't know if that's the case, but i've seen many dyno runs with motocross tires
George Badass that's stupid less friction and contact

Excellent work man!
R E S P E C T !!!
Hello from Slovakia!
Marti I think the Maico 700 may be more powerful, Its a 700cc 2 stroke
2jz_Joakim less power but more low end torque. A Maico 700 makes around 80 hp.
Johnny Lehti Yea, i found out a little bit later after watching this video
Johnny Lehti but this makes 91hp plus the cr500 makes more than the maico it's been proven
It depends on what year of bike we are talking about. The Maicos are very powerful for a motocross bike and the Hondas were detuned during the years for better Engine character.
That there is my dream bike! 2t all day. I would ride dirt thou. BIG ROOSTER TAILS! Great job you did mate! I would be very proud.
Well done mate !! Beautiful bike !!! and very good restoration !!! Beast !!!!
With 91 hp it is a beast!!!!!
You've created a monster!
