More Superbike Engine MODS for the Yamaha R3 [Superbike Build Series Ep.7] 

LOL, Just realized you sound like Justin Hammer from Ironman 2 explaining things, love it lol.

You better also do some insane things with the ninja 400😏

I absolutely love this series you guys put up. Soo informative and entertaining. You guys are the reason I'm buying an r3.

when you guys are done you should make a kit that comes with everything to soup up the r3, I would buy it

As a motorcycle noob, this video is wonderful 👍

Awesome video guys. Lots of information and explanation helps me understand what it takes to make a race bike. I have a CBR300R and I would love to upgrade its performance.

Nice job man that motor is going to sing!...

I could watch your vids on this build all day..its like being at school..love it..learning a lot i am

Sharing machine knowledge I really like because I also pengamina Yamaha R25 or R3 is the same, thank you, friend

Very nice. The work done is slowly shaping up, transforming the R3 into a true 'superbike'. Love that slipper clutch setup. Can't wait for the next episode.

This guy gives a great presentation

The rods expand with heat they don't stretch.

Wow I wish I lived on the States I be bringing my ninja 400 and yamaha R15 to you guys As for the Conrods the Carillo rods are awesome use to run them in my vintage Norton 750 race bike Great video guys

my dad bought a CB 350 in 79 brand new. when i rebuilt it in 1986 in shop class so i could ride it back and forth to school. i changed the cam. match everything up. shaved the head down alil. and man that made the bike alot more peppy let me tell u.

This guy could make his own bumblebee.

Wish you nothing but the BEST dude as mechanic and rider I appreciate your non BS talking

I have heard guys say that super smooth or mirror smooth finish on the intake side can cause gas to cling to the surface or a little bit of "roughness" creates a bit of turbulence to keep the gas from falling out and creating a better homogenous mixture of air and gas. what do you think?

I love this guy.

Worried about rod stretch,throw titanium rods in there.Carrillos stretch and are often heavier than stock rods,good thing about Carrillos is they are pinned and have ARP bolts and can be re-bushed,and you can re-use the bolts multiple times.Carrillo told me 10x,but I checked bolt stretch and replaced after 6th motor freshining.Throw some APE TI retainers in there and depending on added lift you may want to shim them springs.

Great info. These engine episode's of this build series are the best

im getting jealous of all these awesome engine mods !

Are you changing anything with the valve springs? Will you share dyno results when the motor is assembled?

Nice. More powah!!!

Holy Shit you guys went to town with this thing.

Hope he's raced 2 stroke before or that slipper clutch might take him by surprise at first if he is used to 4t engine braking particularly high CR. I'd be warning him that throwing down gears into the corner inst going to help slow him down like it used to.

Holding the valve open longer is called duration not valve lift. If it is lifted higher also it's called more lift and duration.

I love your video's, thank you :)

"Mark Wahlberg" always a cool guy...Do you guys do engine/transmission builds for customers?

I feel like the commentary in this video is sort of patronising, almost as if it's aimed at 5 year olds watching Sesame Street...

Can we get a list of the components used in your build? Who performed your head work? Just found your site, really enjoy the information. I'm an old drag racer and interested in small displacement engines now. Thanks

Bom di sou do brasil..corro de r3 peguei ela agorra ..corria de ninja 300 sinto fauta dessa embreagem deslizante .onde comprou se poder me passar agradeço

Great video series guys - we are racing an R3 here in New Zealand - great to see a well built machine.

nice video, another subscriber

Binging this! So, without a stator, how long can the bike run before you run the voltage below what's needed in the coil to make it go bang? You're running the coil and ECU, right? Nothing else?

Make more videos of racing bike engine rebuild

intake works better when its not "smooth" btw

Omg this guys monotone is horrible,I couldn't finish.He talks to you like everyone is below him.

Steel rods are nice but you should look at ALUMINUM rods they would probably suit your requirements better and weigh 33% less for the same strength.

if my 1983 2 stroke 115cc yamaha had all these upgrades.. she'd make 30hp!

Hope you work on something for the Ninja 300.

Please....Can you explain cooling system in yamaha r3 engine.... how coolant circulate... i cant find where is the bypass hose..

Have rod failures been an issue with these motors when built? Those upgraded rods add a LOT of mass/inertia. Is it needed? Yamaha engineers are pretty good. I would be very surprised if the stock rods did not have enough safety margin to handle ANY HP increases you could possibly squeeze out of the motor. Have you done the rod stretch, BMEP and fluid film stiffness math to determine these are really required? I do like the slipper clutch, especially if you are upping the compression....

Does tst sell a built street version of their engines

the intake port has to stay ruff so there is more contact suface for the fuel to evaporate

Lift vs duration. lift is how much it's open, duration is how long it stays open

Sounds like you described more duration.

Myxamatosis playing?

Its 3 yo video . Is theres a kit for r3 upgrade ?

I'm just wondering if you could replace a traditional clutch into a slipper clutch?

how about Big Bore Kit 350cc or higher?

Does TST Ind have engine building services?

hello. i want to upgrade the orange on my motorcycle R3. do you have it?

Bom dia! Esse comandos de válvulas são de competição? São maiores que o original

Would have been great to start this project on a new Ninja 400.

sometime,... i think, why the factory build an engine with standard function? if you can make race function... but everything is the same, engine can grow up by upgrade and tunning.

This used to be called 'blueprinting'.

What are the front and rear sprocket sizes ?

That was rude of the guy to just kick mark Wahlberg off the set

Hey there,, I just wanna ask 1 question, can or not R3 convert cylinder head and cylinder block MT07? PNP or need small modifications?

Did you flow test that head before and after porting? Wouldn't a rougher intake port tumble and mix the charge better?

@5.58 'Valve lift' is not holding the valve open longer. That's valve duration. Valve lift is valve lift - how much it lifts - amplitude if you like. I think you should clear that up so people don't go getting themselves more valve lift and mashing valves to pistons.

where can we buy that racing camshaft assembly? @13:25

how high did you go with the compression ratio for this build and wich fuel do you intendt to use?

I think you mean Duration, and not Lift when it comes to how long the valve stays open....

Wow! This motor looks very similar to my super tenere 1200 motor. Question I have, my OEM timing chain tensioner (oil pressure/spring) type started rattling on startup. Yamaha “updated” the tensioner to correct this issue. Meanwhile I purchased Graves manual tensioner. What is Your way to adjust proper tension on them? Also down the road do I wait for the “startup rattle” to adjust or there is a better way? Thx!

will this whole kit be available for purchase ?

Did you use Ninja 300 rear sprocket? Because I did..

So the engine will only run til the battery dies?

can you make this engine sound like mt07?

What oil did you run in this engine on the track?

Nice work guys but it's sad to see Japanese manufacturers making these shitty engine's. They mastered 250cc 4 cylinder marvels in 1980's which were revving up to 18000 RPM in stock form with carbs. You guys should build up a 4 cylinder 250 and then compare these so called Morden bike's.

weeeeeeelll

Kaun sa bike hai

12 000 times going up and down? Isnt it more like 12 000 : 4 cilinders is 3 000 times? (assuming its a 4 cilinder motor)?

snorttt 6:45 lol

I am hardcore fan for yamaha racing mechins.. i ma R3 woner in india my bike top speed only 196 kph only I am not satisfied my bike 210 kph is possible dudes pleas help me guys

DEAR TST Can I order the R3 engine sets? Many many thanks 😊 Sam

“Valve lift” isn’t how LONG you hold the valve open...it’s the max measurement it WILL open. “Duration” is how long it will stay at that open or certain configuration. I’m sure you know that (well maybe you don’t, wouldn’t be surprised with the patronizing attitude you have towards your explanations and viewers) and people screw up their terms all the time (I do it plenty myself), but for people who don’t know and are watching these videos to actually try and educate themselves on these things, they might appreciate the proper terms because they are very different even though we are talking about the same actual parts. Not trying to be a dick or know it all by any means because I don’t, but some might appreciate that.

This guy . . .

to hard to watch, how to for dummys

Valve lift is not the same as valve duration.

First 😎👌🏾

You talk funny. Informative video nonetheles..

Suzuki GSX R-125 moto3 build please🙏

u drunk?

Boring

Weeelllllllll

one of the most enjoyable engine build videos i have seen in awhile.
