- Welcome to our latest video where we dive into the nitty-gritty of assembling the bottom end of a 1993 Honda CR250 engine "Project 93, Canada's Worst Dirt Bike". Join us as we meticulously piece together this powerhouse, sharing our insights, tips, and a few cautionary tales along the way.
At the outset, we were confident in our abilities and eager to tackle this project head-on. However, as with any mechanical endeavor, challenges arose that tested our skills and patience. We encountered a few stumbling blocks that, with the benefit of hindsight, we hope to help you avoid.
Throughout the video, we'll guide you through each step of the assembly process, from installing the crankshaft and bearings to fitting the transmission components. We'll share our expert tips on proper torque specifications, bearing selection, and sealing techniques to ensure optimal performance and longevity.
But it wasn't all smooth sailing. Along the journey, we ran into a couple of issues that gave us some headaches. One such problem was aligning the crankshaft properly, which required careful adjustment and precise measurement. We'll walk you through our troubleshooting process and offer solutions to overcome similar obstacles you might encounter.
Additionally, we'll discuss the importance of inspecting each component for wear or damage before installation, as neglecting this step can lead to costly repairs down the line. By heeding our advice, you'll save yourself time, money, and frustration.
Whether you're a seasoned mechanic or a DIY enthusiast embarking on your first engine rebuild, this video has something for everyone. Join us on this journey as we bring new life to this classic Honda CR250 engine, and learn valuable lessons along the way.

Great vids watching from the UK.
Thanks a lot! I’m glad you are liking the content!
That's a good idea of printing off the parts schematic.
Good job you checked the transmission before going further.
Even I make simple mistakes and I personally try to have a system in place to prevent it from happening. I hope the videos and things I do can show it can happen to everyone and hopefully it helps someone with there builds one day
I might have picked up the worst 1992 CR250 over the weekend. Just finished welding up the cases as it had a rod punch through it.
This video is perfect timing!
That’s what we like to do here at Dirt Bike Repair! Give you the info you need, and hopefully learn from our mistakes! Lol.
Thanks for the comment and for watching, hopefully your 92 is not as hard up as Project 93.
The engine might be worse off. But looks to be healthy now. The rest of the beast doesn't really seem that bad upon further inspection. Thanks for the assembly video. Was perfect timing
Do you happen to have a white tank? Trade for a oversize black?
@@narfer I do have a white tank I'm going to have a video on the restoration for project 93 tank.. I think I have a pretty interesting way to restore the white back from the normal aging yellow.. I also do have a brand new tank... but not really interested in trading it though.. sorry.. VMX makes really nice ones that are not oversize... but they are not cheap..
@@Dirtbikerepair Hard to find any decent white tanks.
Great video very informative. Oh and I won't tell your mom about the missing granite lol
I totally forgot to put the breather hose on the 2nd case when I put the motor back together and totally had to McGiver it in with a flat head screw driver, dirt bikes right.
Lol, things do happen when you are getting it all back together. I think the biggest pain is when you do miss something it’s the risk of needing to get another gasket for the one you will damage getting it apart.. lol
Thanks for the comment and I hope your McGivered hose is holding up.
I just redid my bottom end also so far I have about 150 miles on it. 120 of those miles was at the 2024 mint400
That’s awesome! Having the reassurance of knowing what is in the engine can some times make all the difference. It’s a good feeling to know everything is new and fresh when you are doing a build like this
Thanks a lot for watching and for the comment
Great video cabnot wait for finished product!! Keep up the videos!
Thanks for the Support!!
Id say black clutch cover but that's just me. In a matte black
Black might be good for this build. Thanks for the comment
Fun Fact Trivia: Motors run on electricity...Engines run on combustion 👨🔧 I'm jus say'n, Flodaddy ❤
This is true…. Lol. Thanks for the comment and for watching
Thanks for the trivia...
Can I ask where you get your seals, I have a dt80 Yamaha that I can’t find a seal for as well as a 250 1986 ktm that I know needs new seals before it’s started.. anyways thanks a bundle :3
In your situation if you have the old seals or the cases where they go and you can’t seem to find a retailer online. I used partzilla for project 93. It’s good to remember every town that has any kind of manufacturing probably has a industrial bearing supply place.. they might be able to get you the seals that you need if you can bring them the old ones or the thing you need to install them into. That’s what places like that do for a living and they specialize in figuring that kinda stuff out!
I hope that helps and thanks a lot for the comment. Sometimes thinking outside the box can work for the older bikes.
Where is the Kokanee? You can't assemble an engine without it. You might get dehydrated.
lol... trust me this engine had me stumped.. that transmission was being really tricky and about to drive me to drink for sure... Thanks a lot for the comment and for watching
How much can I expect to pay for a rebuild kit like the one you purchased? I live in Peoria, Illinois.
up here in canada, from a canadian retailer they are $900 but i think you can get them in the USA around 600-700
Their is no sound
I have sound, but I will definitely try to see why you don’t…. Maybe UA-cam thinks there is some kind of copyright thing going on.. thanks for letting me know and hopefully I can get this fixed for you ASAP!
Man I hate to see people use Chinese bearings seals and cranks. And the have 7 balls. Cheap $5 to $10 main bearing.
OEM is 8 and a way better
bearing . At the end of the day you save $150 over part made in Japan.
And you do not press a crank in the motor at all.
I have never had a problem with any of the "All Balls Racing" products, I'm not going to say that the OEM Bearings are not good. OEM are really good. I just have never had a problem with any of the Wrench Rabbit kits. They always go in really good for me and seem to hold up just as good as any OEM builds I have done so I'm really curious to what makes you say they are no good.
Why do you not think that all balls bearings are "Cheap" have you had problems using them ? and if so what bikes?
I hope we can figure out why you had a bad experience so i can try to avoid it myself, its always good to get peoples opinions and to learn something from there experience.
Thanks for the comment and for watching the video, hopefully you like the content
@@Dirtbikerepair it's all crap that break cases from China
