Holy crap dude... You're making me cry over here. The 1975 Yamaha rd350 parallel twin two-stroke was my first bike I ever owned. I bought it in 79 so it was only 4 years old. It was wicked fast and I admit it did scare me. I owned it till I got my first Honda rd350 and said goodbye to the two-stroke. It still holds a special place in my heart and yes I still ride today at the age of 58. Warms my heart to see these things still on the road. Nice.

As long as the bearing journals are acceptable the pitting in the case shouldnt harm anything.

Agreed. The pitting is all in non-critical areas.

Unless you hold the cases up to the light and seem pinholes he couldve used those no problem, bigger issue is, did he send the crank out and have it pressed apart and all new seals between the cyls and on the ends, if not it will seize up and throw him over the bars in the first couple miles- Trying to drive a Multi-Cyl two-stroke with old dried out crank seals is just asking for stiches

@@Mad-Duk_Machine_Werkes give him some credit. He is capable of all that which you mentioned. If the crank was/is in similar shape as the rest of the motor i'm sure it was pretty crunchy in those bearings. Rebuild, run good oil at a good ratio, and that'll go a long ways Vasily.

YES! That is indeed looking EPIC. Lomas pipes too. Nice! If you’re still struggling with rear suspension geometry, you could do a lot worse than just copying the RD350LC /early TZ rear monoshock geometry. Definitely an R5 non-reed engine in an RD chassis. PS if you want to tidy the rear end up, you can set the stinger pipes deeper into the belly of the pipe so they stick out less (but instead stick out inside the belly of the chamber. PPS The pitting on the crankcase chambers doesn’t matter. Only the bearing and seal bores plus the mating surfaces must be free from pitting. Use the reed block barrels, much nicer to ride than the R5 piston ported jobs.

The bike is a RD but there were lots of R5 parts on it like the side covers, oil tank, fuel tank, etc. The engine you pulled out was an RD, the engine sitting in it is a R5, RD = reed valves, R5 = no reeds, they were piston ported. I've owned and raced both!

Good catch I don’t know too much about the Yamahas but it is also possible that it is an r5 bottom end with rd cylinders if i remember right they were swap able

@@joecurmaci5880 Thank you, I love the Yamaha two stroke twins, they are strong and fast. If I could post a photo I would show you my RD/R5 dirt track bike, I'm 66 years old and my race day's are done but my plan is to try and find a younger person to buy it and put it back on the track where it belongs. It looks great in my garage but I didn't build it for that!

Hey first time watching your channel. Awesome build . Just wanted to leave a welding tip. I have 18 years of welding experience 10 of those including Aluminum. you need to change your cup size to like a 6 or 7, and don't leave so much of the tungsten out. 1/8" max. You will get much better gas coverage, eliminating the carbon . keep up the good work

Heeeyyy great build!! Absolutely love 2 strokes

Love these bikes ,I had several back in the 80s ,would love to have another one of these bikes again .

Vasily.... dude you have mad skill so please dont take this the wrong way but if you could, STOP WELDING AND CUTTING NEXT TO PRESSURE LOADED SHOCKS!!! Brother, my buddy got half his face literally blown off of his skull because he was dumb enough to weld next to a shock mount just like you are doing and as you can guess, he didnt make it. PLEASE please be careful man, we love watching your vids and dont want to watch your funeral. Stay safe.

Thanks for doing these videos on the RD/ R5, its nice to see the younger generation embracing the bikes I grew up with. You have motivated me to get back into building bikes, thank you for that. I dragged my 71 R5b into the garage and am in the process of building a street tracker, I'm pumped about it. I bought a Ducati 750 Monster front forks & triple trees and RZ350 wheels and brake rotors. The engine was fresh many years ago and I put it in my dirt track bike with all the race goodies and it rips. I have the ported RD engine with RZ reed cages that was in the dirt tracker ready for the new Vito's crank and Banshee pistons. Great job Vasily, thanks for getting this old man off the couch and back in the shop.

Great job on the seat looks awsome! The bikes really looking good! Mixing gas and hauling ass!

This build is sick !!!

Build the same setup on the extended swingarm. It will soften up the suspension slightly.

@laymanengineer7502

I thought the same thing. the stiff shock w/ longer swing arm.

This is such a cool build I’m glad to see another video with more progress

Never worry about criticism stay focused and determined success always happens

Couldn't afford an RD, so I "graduated" from my X6 Hustler Suzuki 250cc street twin to (of all things), a Jawa 350cc with no rear shocks, so I was content to hardtail it until I found a set that would do the job. Finally wound up with a Yamaha YDS3 350 twin and I just went nuts with it. Used a pair of DT175 cylinders and pistons, an unspecified set of close ratio gears, changed drive chain ratios and found myself with a reasonably capable machine after a bike mechanic offered a free port and polish if he could have the first ride. That boy knew his business and he even used my Commodore 128D to formulate and weld me up a set of torque pipes and threw in a set of larger carbs which he taught me to rejet and tune. After that, it was a hellbound rocket buzzsaw and I went up to a 530 chain so I didn't have to keep buying new, OEM ones. By that time, the writing was on the wall. When my YDS3 was stolen, I made the only reasonable jump, to an H2 Kawasaki 750cc triple 2 stroke. Probably more for the goose flesh that hit me at about 5,000 rpms than anything else. Well, enough about me. Next time you find corroded inner cases, just use Epoxy. Makes things a lot simpler and cheaper. Have fun, you're gonna love it!

This is quite the build, good on you for taking it on!

Just keep your head up, stay positive, and have fun doing what you are doing. I enjoy your content greatly!!

You are a awsome fabricator....love your builds

Awesome build can’t wait to see the end result.this young man has got some talent well done keep the videos coming 👊🏻 respect all the way from the uk 🇬🇧!!!

I've been waiting for this💥

That exhaust is crazy! Nice work!!

Holy smokes, this is a crazy awesome build. Keep it up!

You get the parts when you get the parts. We'll still be here man. Great work!

Yeeeees, finally a video on the Yamaha 2 stroke. I love those bikes but guys out there who have them want way too much money for them, hope you get it finished soon ride safe.

That bike looks like so much friggin fun! nice work.

That thing is sick! Nice job man.

Great progress.. looking fantastic!

So glad you saved it from the trash heap. It is an awesome bike and the build you are doing is looking fantastic! That seat pan is sweet! 👌

Can’t wait to hear this thing rippp looking sweet man

I've been into these for 40 years! one tip I can give of fhand is to cut all the cross braces off under motor and put a simple tube in about 4" in front of old brace. then take kickstand pivot piece and weld it to cross brace and frame. this lets you put better angle on it and it don't hit them fancy pipes when folded up

Looking great can't wait to see the finished product

Looking forward to see this bike run and drive!

Definitely one of my favorite builds. It's gonna be suprisingly fast I bet.

This bike is going to be an epic ride! I still remember the first time I rode a stock RD-350. I had a '76 Honda CB750F, and it was a fun ride, but a friend with an RD-350 suggested we trade bikes for a short ride, as he wanted to see what the Honda was like. On that RD, I felt like I had just sat on a bicycle, it was so light! The first time I grabbed the throttle in first gear, and the front end came up about a foot or so, I was really impressed! With the new chambers and port work, this bike you're building will be a real sweet ride!

Pipes are gorgeous!

Coming along nicely. Good work.

Glad to see this series I’m about to rebuilt an rd200 for this summer!

You are fuggin' killing this build man. Keep up the great work!

Insane build!!!

The bearing journals condition and size,the case mating surfaces,and the bolt holes are what's important providing the cases aren't windowed... None of that etching or corrosion pitting matters as long as it's not all the way through... Those cases look good and usable as the journals weren't scarred or worn down...

100 percent correct. None of that pitting is of any concern

Hell ya buddy!!! St legal 2stroke. Worth every penny and all your hard work!! Always looking for bikes like that

Bike looks amazing. Love all the work you have put into it. Cant wait for the next episode. You should put some better front forks on it, The suspension is a very important part of helping you keep the bike on the road and getting all the grip from the tires that you can. Go to ebay and find some cheap usd forks(something like a fork from a Aprilia rs 125 would be perfect for a bike like yours) And if i that pited engine you have was mine, i would use those engine cases. I dont see anything that should make any problems. And for the tail area of your bike, Time to learn them glasfiber skills. And make a perfect copy of what you have in your head. Good luck building the bike, and thanks for taking us along the build.

Оооо наконец-то доделал. Поздравляю 🥳

Im really liking this build!

I love this build. I haven't apriciate a spot where can be critical the pitting. If the pittng isn't located where the bearigs or seals are sitting everything is ok, the pitting could have eaten a lot of wall too. I would try it if the seals and bearings sit properly, and check for some to thin walls, in the case appears one, just add some material to the wall.

Awesome Cafe racer

I bought an RD400c , new, in ‘76, my cuz and I were the first in Eastern Canada to get these giant killers and we drove’m like we stole’m. My brother and other cuz picked up a pair of ‘76 Honda CB 360T’s and they were pretty good rides as well, but nowhere close to the RD’s. I’m 65 and I still remember cruising down Saint Catherine street in downtown Montreal and getting the looks from many people and other riders. The Yamaha was the first production bike to get 1) self canceling turn signals 2) Alloy Mag wheels 3) Disc brakes Frt&Rr ( for its cc’s) and we had Flat bars installed at the dealer. Canada’s colorist we’re Black/White and Gold trim work and name badges. Killer look and Giant killers, we had NO problem with any bike, up to the Kawasaki Z-1 900, just a wonderful machine which I’ll remember to the end. Fantastic build, enjoy it safely for a long time, it’s a memory maker.

yooooo those pipes bro sick!!! love a good expantion exhaust

Hell yes dude get noticed!! I love your videos keep it up baby!!

Great job

Al fin lo espere dos meses fue demasiado 🤧🤧 espero que el siguiente episodio tarde menos

I thought I was over my bike life. Now i need to start looking for an rd again. I am blaming you when my wife finds out. Keep up the great work! Looks great man!

Those pipes you got for that engine are sick. Ripper for sure

Rad video.

Looking, good bro! The pitting in the bearing carriers is no issue, I would definitely reuse it. Put the extended swing arm back on with the same setup, I bet it would feel just right. Anyway, keep it up man, killing it, the bike looks savage!

Can’t wait

Super RAD bike. Pretty cool man

That exhaust is nice

Good video vasily

Ngl that is a sick swing arm

It’s a press together crank with roller bearings, right? If so, then the pitting doesn’t matter. If regular bearings cover the pitting, then it doesn’t matter.

Pretty dope

I absolutely love this build man I have been chomping to do one also but time and money are holding me back right now unfortunately.

Next video bro!!! 😎 Your a very talented guy

Cool brother 😎

Pitting in the KC area will not be a problem as long as it doesn't leak when you put the oil in it. If you're really worried about it, clean the pits very good with some brake clean, and spread a very thin layer of JB Weld on it and then polish it back out after it has cured. That way at least you know the case will not leak. The case is not a structural part of the engine in that case. The structural part is what holds the bearings. All the case does is keep the oil inside it. Quit sweating the small stuff. Congratulations, you're the first one I've ever seen tack welding frame Parts onto a vehicle with the MIG welder even close to the right temperature and settings. I would still have a little bit warmer than that but that's pretty good. Hopefully you're using at least 80% Argon

Looks sweet as it is man

Looking good, hope that shifting issue is not a problem.

Badass!

Hot wheels!! First thing I thought of when I seen your seat design.

Loving the build dude. I did a similar one with an XL600R, ivernted KX forks, CR swingarm, 400ex shock. A little more travel, super tracker. I think your shifter arm needs to be longer. Not enough throw.

Make Sure you leave enough clearance between your shock mount and the tire, the tire will grow taller at higher speeds and ya don't want it rubbing and have to redo it after it's all painted.... Also if you ever decide on a taller tire you will be SOL, easy fix now... Your doin a killer job young gun!
