This channel is so underrated
Appreciate it, hopefully not for long!
So is my mother. Check out her OF
@@KincadePavich I hope so too love your content bro 😁😁
@@KincadePavich your channel got push to my recommendations so hopefully the algorithm is on your side! love the video man
@@Fee.1 already did now my phone is all sticky
I just put a Wiseco crank in my CR125. I’m having some setbacks as well though. I used locktite on my bearing retainers but I’m still nervous they will back out. Cerakote looks awesome man!
Thanks a ton! I think my RM125 was just a special case... I've built quite a few engines, and that was the only time that ever happened to me.
I appreciate your honesty in showing your mistakes as well as successes.... Good job!
Just got to the end of the video. GORGEOUS!!! Don't forget the "freeze the bearing and heat-up the receiving part" technique. You'll never do it a different way again!! The bearing will literally just drop right in!! (ALMOST every time) Thanks for the content!!!
Awesome man I'm glad things worked out. Its an absolute beauty. 💯 Looking forward to the rest of the build. 🤘
Thanks a ton!
How about a video on all of the tips, tricks, and settings you’ve learned for ceracoating?
Great job KP!...thanks for always going the extra mile to make sure everything is done right...this build is gonna be mega sick once it all comes together!
Thanks Dan! Appreciate the support!
Truly impressive, love to see the progress. Very good channel👍
Thanks Lukas!
I'm excited to see where this project goes - cool stuff dude!
Appreciated!
This bike looks clean af👌good job
😄 crazy all the hiccups! Great work making these videos, the world needs more people like you. I have to edit my year build footage of my wr 500
Much appreciated! Yep, I thought this was going to be done weeks ago but kept running into problems! Stoked it's finally together.
GREAT WORK DUDE, LOVE YOUR VIDEOS MAN, BIG FAN!
Thank you!!
Absolutely marvellous job love your attention to detail this engine was built with love & care really like that double checked everything was perfect im from the United Kingdom I wish you were from the uk as I would be entering this competition Have a marvellous weekend kincade beautiful work you genuinely do amazing job beautiful content 👊💨
Thanks for watching John! I wish you could enter too, but thanks for following the build regardless!
Killer build, video and can’t wait to see it throw dirt!
Yewww she's getting there! Thanks for the support!
She's gonna bark and crack like you never heard before. Nicely done. FWIW... all the way through I kept thinking man, that crank assembly looks nasty. Turns out, my micrometer eyes were on the money 🙂 Bike will probably glow like a star when put together. Seriously, nicely done.
Haha good eyes! Appreciate the support!
Yessir been waiting for this
Hope you enjoy!
Best dirt bike channel out there
Thank you!!
Badass. Nice job
Thank you!
I've always wanted to build my own crank jig because they are so expensive, and if you have the jig (and a press, but those are cheap and useful elsewhere) and some v-blocks and a dial indicator, then it seems like a simple job.
I have a Pro-X crank in my YZ, as well as clutch basket, piston, and bearings. But I've used Wiseco cranks in other bikes.
If you get some cheap SPi v blocks, you can spin something round like a crankshaft using a cheap indicator to check run out before it's in the cases. I am in quality assurance in a machine shop👍
So clean
Thank you!
Wow… I give you credit for replacing the crankshaft. I personally would've ran it and prayed… Lol.
We need a 300 2 stroke class.
Use heat/freeze to install or remove a tight tolerance part
Man I've heard nothing but bad things about that crank. My builder refuses to install them. Oem is the only way to go for a crank.
I have a press and have broken the clutch basket in the press also.
Great work!! But the clutch cover is going to look very bad in a couple of weeks. Raw magnesium oxidises very fast
Another good trick that I'm sure you are aware of, but if you put your bearings in the freezer overnight and then heat up your cases/whatever is going to accept the bearings, they will drop right in. No pressing or beating necessary. I'm sure you know this though.
How does one measure crank run out? Is that different jargon for end play?
I have a yz 80 im not sure if its a similar 2 stroke but i was riding and the kickstarter jammed up completely. I checked the piston and cylinder they aren’t scored or stuck together. Any tips or ideas on where to look because i am lost 😢
I want two, one in a frame and one on my coffee table, Phathead heads are awesome bits of kit, interested to see the electric start kit fitted, Did you switch the stator plate for battery charging, seems crazy selling the kit with a none charging stator, competition use it is not big deal but road use it is,
Yes, I used the charging system on this one!
I have RD 125 cc twin, 1975. Can I modified into 270' crankshaft. Any idea KP ❓. Thanks from Indonesia 🙏
Badass
good amazing yamaha
Kincaid, is the bolt holding the primary gear on the crankshaft, wet side, right hand threads? I'm having trouble loosening that bolt. trying to put in a new crankseal on my yz 300. thanks, your' video's are top knotch
Hey, yes, standard right hand threads. Torque should be 40ft lbs so it can be tough to break. Should go pretty easy with a breaker bar or an impact though!
I have a 2001 and I'm doing a pro-x basket and my Kickstart gear just fell off the old oem basket... should I be worried?
I don't think so - only specific years and models are like this. For many baskets they just slip in. If it was a press fit one like this, it would've came with instructions
Hey, Kincade! Motor looks great. I would advise against using a Wiseco Crankshaft. They are poorly made. They are not made in the USA like the Pistons. I am surprised Wiseco puts their name on them. I believe they are made in China with subpar materials and are often not true. I would get an OEM crank, or have your factory one rebuilt by a skilled machine shop with a PROX Rod. I offer Crank rebuilding services as part of my small business and rebuild a lot of them. PROX, and VESRAH rods are made in Japan. HotRods connecting rods are made in the USA and are great. HotRods complete crankshafts are made in Taiwan and are just okay. For OEM Quality go with a YAMAHA Crank, or have your stock crank rebuilt and trued with a PROX or VESRAH Rod. Especially since you are going with a 300BB and have spent a lot of time and care to make such a nice motor. Excited to see the outcome. -Beau
Hey Beau, I appreciate the comment. It seems this is still the widely accepted reputation of Wiseco cranks based on comments on this video. I'm curious if this is a result of previous failures that tarnished their reputation, or if you have reasonable evidence to believe they are to this day still no good. Talking to Kevin at Wiseco who I've been working with for some time, he truly believes Wiseco is now developing a quality crankshaft and admits that they weren't always. All this said, I'm not claiming to be incredibly well versed in the matter and don't have enough builds under my belt to prove or disprove this. The engine is bolted up and in the frame, and I hope this crankshaft lives a long happy life cycling this piston up and down. I am certainly not just ignoring these comments, and would love to get to the bottom of whether people are still experiencing Wiseco crank failures or not. All of the forums I seem to find discussing failures are from many years ago.
@@KincadePavich Thank you for the reply. Curious, did you see if the Rod had any origin marked on it? I see on Wiseco's article a "Made in Japan" on the rod. But I kind of question whether those were R&D cranks or not. I havent seen a Wiseco crank with a Japanese Rod. As far as evidence I don't have photos or things of that nature, but I can tell you I have physically replaced 3 Wiseco crankshafts in the past year that have failed prematurely. The big end bearing wears out quickly best case. Worst case is the rod breaks and wipes out the entire motor. Not to mention some runout issues from the factory. Obviously I do not know the entire history or age of the Crankshafts I replaced since I was not the one to build the motor before they came to my shop. I do know that most of the time if there is a bad crank found when I am rebuilding a top end, it is almost always a Wiseco. They sure do look nice. But the quality of materials and manufacturing in China just isn't as good as the other options. The way I look at it is why use a Chinese crankshaft when there are Japanese options available for similar money? If you get a rod kit and have your factory crank rebuilt to OEM specs you will likely save a good chunk of change too. I know you already have the motor built, and I am not suggesting you pull that one apart. I also wouldn't lose sleep over a Wiseco crank being inside that motor. I only commented because it seemed like you were still in the process of making a decision on which crank to go with and figured I would offer my recommendation. I am excited to see the final product. The bike is going to be really cool.
I sure hope you are having the machine shop pay for the new clutch basket. That's really unfortunate that they didn't do their research before pressing the gear. Best of luck!
They did. They handled it very well. It was an interesting situation because the ProX basket was provided under sponsorship, but they were out of stock of Wiseco baskets so I did purchase the new one. Had Wiseco been able to provide a basket under sponsorship I'd have liked to not have to take the machine shop's money, but that's how it ended up working out. They didn't really give me a lot of details on why they couldn't get it straight, but essentially they called me and said "hey, we screwed up, we owe you a basket." Apparently they don't offer that sort of work, and the guy who agreed to do it shouldn't have. But very pleased with how they handled it and I feel bad that it had to cost them money.
@@KincadePavich You seem like a really nice dude, they screwed up for sure but it sounds like you handled it well. That's awesome. Can't wait to see the finale video of the YZ300!
Hi, like what you're doing. Can you recommend a company to get bearings and seals for a 1982 yz250, I can't find someone to get it all from one place. Thanks
I would check rocky mountain and see if they have the OEM parts available!
kinda reminds me of mike sabo who does ther same with quads
Such a nice bike to be trashed by a wiseco crank. Do your research they are garbage they’re never in true and most of the times the position for the timing is off. I would highly recommend using a factory crank before you grenade the engine 😢 I refuse to install their cranks at my shop. However i do recommend their forged pistons
Nice motor bike sir
Thanks Raymund!
Yamaha changed that bearing on the shift detent roller, so that new part should be an upgrade.
Someone else pointed this out - I should have used the updated part. I ordered one for an '05 and they didn't make the new part number supersede for the older years, I looked it up after the fact. Hindsight 20/20.
@@KincadePavich Well I never had any problem with mine, I only replaced it because I had to rebuild the transmission.
I wouldn't worry about it.
Dope channel, pro version of myself 🤣🤣. Can you please tell me your view glass set up for your cabinet as mine is super ashy 🤣
I just use the throwaway plastic sheets that stick onto the glass, but the most important part I've found is proper dust collection. Before I had my dust collection working right, it would be unviewable within 15 or 20 minutes. My vacuum runs the entire time and flows well.
@Kincade Pavich thx, yea I have the dust deputy set up and run my lil husky vacuum clears it up the dust really good.

Sorrry sir for asking what camera do you use
I use a GoPro Hero 10 and my iPhone 13
@@KincadePavich tq sir
Is that a WR transmission?
I don't think so... why is that?
@@KincadePavichpeople commonly swap the WR or YZ250x 3rd, 4th, and 5th head gears to obtain a wider ratio transmission. I believe Rocky Mountain ATV actually sells a kit to do so.

Second!!!
First!!!!!!
I'd suggest to NOT use the wiseco crank. Signed, a professional.
Hey there, would you elaborate on why you think that?
@@KincadePavich I've seen brand new wiseco complete cranks snap rods in less than 5 hours MULTIPLE times and those having been used by different people each time, over a number of years. I will not sell them, I will not install them, i cannot recommend them. Wiseco makes a fine piston, stick with OEM rods or have crank works build you something better than OEM.
one sub frome me
Welcome to the channel!
Awsome motor. I have a 300 kit on my 08 . It rides like a tractor in the woods. Just want to let you know that the shifter stop lever you replaced were a common issue. The fix for that is to get one from a 2016 or newer since they upgraded it. The part number is BF1-1814-00
Ahh good to know! I'm surprised they don't just supersede that part - I just checked and I did indeed order one of the older style ones. Hindsight 20/20.
@KincadePavich one thing I do when I get a bike I research for any possible trouble areas that consistently occur and see what is the best way to fix the problem so the bike can be reliable. But it is hard to think about that stuff when you want to ride and just do a build and thinking everything is good to go. I've had stuff like that happen to me before
YOU CHANGE ALMOST EVERYTHING - PAYING A HUGE AMOUNT OF MONEY FOR ALL THESE COMPONENTS !!!!! YOU SCHOULD BUY A BRAND NEW KTM ENGINE 300 TPI -- AND MAKE A MODIFICATION TO YAMAHA SCELETON IN ORDER TO FIX THE NEW EGINE !!!!!!!
First of all this is WAY cheaper than buying a whole 300 TPI engine, and what fun is that? This YZ300 is gonna scream!
