Ferris makes plus 3mm intake valves and plus 2mm exhaust valves know how they perform. I already got a 5mm stroker crank installed with a 105.5mm piston, I went with 11:1 compression piston.
I'm pushing the limits of pump gas on my raptor 770cc I kept compression at 11:1 but went big on intake and exhaust valves. It's at DR Motors in thief river falls mn getting freshen up. Dennis the owner use to be big into racing mini Sprints when he was younger and custom building his expansion chamber, he got a lot of hp out of 600cc in a 2 stroke. We shall see soon how my raptor 770cc turns out.
I only did a 105.5mm big bore kit with plus 5mm stroker crank plus 3mm valves intake and plus 2mm exhaust along with efi controller freed up air intake and exhaust. 11:1 compression piston, plus few other things. I wanted to run pump gas. Hinson clutch basket ect... probably should have done a lockup clutch kit. Stage 3 cam. Idk what my raptor it at for hp. But it's good enough for my back woods riding.
My 09 had DMC twins, hot cam, intake, and installed a tune. Didn't have it on the dyno myself but it ran incredible. I was racing a guy with a high compression piston yfz450. We were at this sand pit and I was running stock tires. He had paddles and I was waxing his ass. Guy was asking what I had done and was shocked. I have a stock 2020 yfz450r. Debating if I should go back to the 700. I miss reverse. lol
Great video brother! Have you ever discussed the oil sprayer mod? If so which video and if you haven't could you, I'm interested in knowing more about that. Also I recently sent you a message about having you tune my Raptor and I haven't received a response back. What is the best point of contact for you?
Man that's a sick build. Thanks for all your awesome vids. I'd love to have a 85-90hp motor . What's the price range for all that's needed? if you don't mind saying. Thank you
That's alot of power for a quad. I'd imagine everything has to be beefed up to handle all that power.. but man I'd love to have one. That sounds awfully super fun if I don't ripp my arms out of my sockets!Haha. You deff sound like you know your shit which I love. I'd have you do your thing if I had the $$
I'm looking for a 900cc Big Bore Kit and a turbo setup. I can't remember the site and I can't seem to find it but they had a Yamaha 700 Raptor R with different size Big Bore Kits. I think up to 900cc. I remember they had 734cc and 815cc is what I remember and the site showing a Yamaha 700 Raptor R with 180 hp and a Yamaha 700 Raptor R with 200 and something hp. I thought I would show you this company Bundy Built Racing. I know the owner who has a long history in racing with all the factory racing teams and 1. being Pro Circuit Racing. He was the shop manager there. Then went on to Joe Gibbs Racing and Joe Gibbs son has passed on who ran the shop and now Bundy the owner owns it. They also build Drag bikes and drag quad engines dirt bike engines etc. They also have a midget sprint car engine that his son races that have a Honda K20 engine with over 400 hp. They bought it at a junkyard for $500.00. They are not cheap but you get what you pay for. Some people think some places they go to are too expensive and they think with their wallet and have problems down the road. These guys are not afraid of going MUCH deeper with the Bore size on your engine. I know the owner, Bundy. This guy makes things go fast. When he would move to another company everyone wanted him because he is the best and knows how to build an engine the right way. They ship all over the world. I thought you would enjoy seeing his company. They have other great mechanics too. Somewhere there are videos about the owner and one of his this shop and about the owner how he got started building engines. So I have seen on TH-cam quads that have 500-600 hp on a drag quad. I'm looking to make as much hp as I can with the Yamaha 700 Raptor r as I can. Thanks for sharing. bundybuilt.com/
Loved the video you always give me new ideas for my raptor When my 2019 raptor needs rebuilt I want to send my motor to you for a big bore maybe this setup how much for the 85hp And Why dont you recommend doing the high hp pump gas build
@@tweb2007 what you just said literally makes no sense "good luck beating a 90hp 4 stroke with a 100hp 2 stroke" dude. The 100hp 2 stroke will obviously win. Weighs less, more power..
John not what I’ve experienced actually racing them. You are right though that you can go faster for less money on a banshee, your comparison points are just a little off from what I’ve experienced.
@@OGKILLa9365 that's where you're very wrong. Overlay a 90hp raptor with a 100hp banshee and you'll see how much broader and sustainable the 4 stroke power is. If you just take peak numbers it's not an accurate representation of how much useable power without an overlay from a dyno
@@pw383426 doesn't make no sense. If the raptor has 90hp. But raptors weigh way more. And if the banshee has 100hp and weighs less. It's common sense to me the 100hp banshee will win..

Did you do the work yourself?
I appreciate the information.
How much would cost build engine like that 2020 raptor 700r

Epic as always !
I cant decide between something like this and the 740cc packages you are doing...
What’s up Daniel got a 2019 raptor what’s the total more or less to send you out the motor stock and get this kit bolted up by you on VP 110
How does this setup compare to turbo Raptor in sand dunes?
Boa noite quais são aa peças necessárias para chegar nesse 90cv? Vc vende este kit?
Nicely done! That motor should make a some guys happy!

Yes i have . Im Going to be doing another video on it soon
Email to sales@cuervo-racing.com
@@MrCuervoRacing Sorry bro I must have missed that video. And thanks for the email I'll go ahead and shoot one over to you! 👍
A bolt together kit like that is a dyno 100% required or can we tune with a vortex
what cc tuning is best for long life for everyday
804 and below
Can you build this engine for my 2023 raptor and what's the price
Man that's a sick build. Thanks for all your awesome vids. I'd love to have a 85-90hp motor . What's the price range for all that's needed? if you don't mind saying. Thank you
Please do a ss/sb build video next, something with 70-80hp!!!!! Not all of us want to go big because of our riding terrain.
I've seen full race sb/ss cuervo builds. They're nasty with a lectron
What does ss/sb mean?
@@spencerwilliams6399 stock stroke stock bore
Is that piston 14-1 or 12.5? And is that a o-ring groove on the head?
Great video, what kind of fuel tuning should come with this setup,....pcv?
Do you do anything to ignition timing?
Can manufacterers build one of these big single cylinder engine from the factory????
Great info!!!💪🏽💥
Impressive that is!!💪🏾🔥💯I wouldn't mind having one!
What is this piston

do you have any engines for sale for a raptor 700?
Very nice.
that’s a whole ass r6 😂
That is my next build can i just pirchase the kit from you guys ?
Could this be a trail bike
With this tuneup i wouldn't. Id dial it back. Kinda pointless over 70 hp on dirt tire
Boa noite amigo vc consegue me fornecer este kit?
Would this build still be reliable?
they stay together pretty well is used properly and not abused. this is pushed fairly well for the cc size. 75 and below hp is very very solid/
Would this build work with standard exhaust or would I need a drag pipe?
What about on a 2008 raptor 700r?
same results on that year as well. basically same parts except the head
Nice. Sent you a email and a message on messenger.
What is the best fuel to run, and what type does this beautifull engine run on?
This one runs on vp c85.
Where are you located
Eugene Oregon

And Why dont you recommend doing the high hp pump gas build
Fuel consistency is the issue
Is it possible you can just send me the whole block and everything else that comes with it? 😂
My brother bike make 105 to 110 hp
Why? I can make my banshee put out 100hp with less money and less labor.
