I ran it out of oil! 

On the bright side more content...

when you have oil out for a while its good to put a tag on the bars with "No oil" on the throttle. That way anybody that attempts to start it can see the tag.

I remember the time that I rebuilt my 400EX and I did a high compression big bore ported, stage two hot cam, kibble white +1mm valves and springs etc etc... Took it for the test drive after building it for weeks and weeks little by little, and it kept dying and it sounded like it was pre-detonating, so I thought that’s what it was (it would always fire right back up) so got home poured race fuel into it thinking that was the issue just needed higher octane due to the 13:1 Compression..... it still did it and then I remember looking on my bench there was this little metal gear, didn’t think much of it. Something told me to pull the oil cooler line and crank it and make sure oil is pumping... so i did that and no oil came out, then it dawned on me that I forgot to install the oil pump drive gear! Happy ending though because all I had to do was just replace the cylinder and piston. now get this is a totally true story here... So when I originally bought the first piston from Weisco Pistons they so happened to accidentally ship me two! When I originally Contacted them and they said they May have shipped a 2nd one out by accident but there might of been a mistake and they told me to just keep the other piston. In the end it worked out perfect though!

Project big bore????

I just rebuilt my crf450x and had a dream that I forgot to put oil in it haha. First thing I did when I woke up was put the oil and coolant right next to it so I wouldn’t forgot. Runs like a top now!

You’re just a wealth of knowledge. I love your videos, always learning something from ya brother. Keep it pryme!

The good part is now you dont need gloves to open this engine🤣🤣 Nice work as always, I'm glad you have stopped this engine before it was completely trashed👍👍

You know youre a 2stroke guy when you forget to put oil in a 4 stroke😂

That bike is pretty much indestructible Honda knew what they were doing when they designed that. Great video 👍

Place the ignition key in an envelope marked "NO OIL". Place that in a safe place in another room. Tape over the keyhole, mark it "NO OIL". Glad you saved the bike and congrats on your engagement. Happy days.

Always learning something with the vids 🤙🤙🤙 keep em coming!

This is my favorite video you’ve made! I learned so much it was unbelievable. Thanks!

When I was 14 my 2010 YZ250f oil plug blew out and I rode for about 20 minutes and 6 miles before knowing I had lost all my oil but I filled it up and put a new plug in and rode the piss out of that bike for 3 more years and just sold it running like a champ this year for 3,000

Hey Cameron, A little trick to change the timing chain without taking the engine apart. Break the old chain while its in the case. Break the New chain. Hook them together temporarily. Pull the new chain through using the old one. Once the New chain is in place take the old chain off and hook the new one back together. It is a bit tricky at first but once its done once it is much easier that screwing with splitting the case and tearing into other stuff. Loved the video, always super descriptive and well put together!

I appreciate the honesty! Transparency is what makes people like you!

Thank you for being straight up and honest , I love your channel plz keep making vids for us you-tubers.

I use shell Rotella T in my air cooled 4-strokes too!!!! Great stuff for a cheap price!!! If it’s good enough for a D3 dozer and a transfer truck, it’s good enough for a single cylinder bike lol 👍🏻

Even the best make mistakes, don´t be too hard on yourself! :-)

Camera quality is sweet, and love the video!

Don’t worry. I managed to only put 200ml of oil in a 1975 cr125. I only noticed when the clutch started slipping after around 4 hours of VMX racing. Happens to the best of us, and me

First video of yours I have watched. Like your calm style, clean work area, as well as good camera quality. Congratulations on your engagement.

GREAT Video Cam!!!!! As usual, Very Informative and Enjoyable as well.

Congrats on the engagement! Your videos are great man, keep it up!

GREAT VID!!! Cam. I love your stuff.

Great how to rebuild a small 4 stroke. Some great tips in there. I'll be using these tips for sure.

Your videos are so informative i feel like by watching your videos i could rebuild my own engine

I'm sorry this happened, BUT it's a pleasure to watch you work bro, I enjoyed every second of this video, learned a ton like always 🙏🏻

The more I watch you work on bikes the more confidence I get to do my own work. Thanks!

I think you get a pass on forgetting the oil haha! Congratulations man!

Love your videos and your builds. Stay strong 💪 dude.

Love your videos bro 🔥👌🏽

Cam i love your videos man! Learned so much

Tip I learned from the interwebs on timing chain replacement, pop a link out of the old one and the new one, link them together and spin the motor over until new chain is all the way in 😉

At 1:20 You meant to say " Check your oil and fluids before you propose" LoL

Man finally you are doing serious business here with that Sony!! Very nice shooting with that super camera!! Keep it pryme 👌🏼

My favorite channel man. Man I would love to have one of your bikes. I would never depart from it. You do great workman and great videos

love your honesty cam

Congratulations on your proposal bro. Subscriber here from the Philippines. I really appreciate how you do your builds. its amazing same as Adam and Dirt N Iron. such an inspiration for a me since i was modifying and restoring bikes too.

Your videos are soo relaxing to watch...keep on the good work🙂

Nice work cam your the best love your work mate patience is the key to success and your got patience 100 % 👌

Man, that is so much more complicated than my 33 year old Honda. I have a couple caps for timing marks instead of taking the whole cover off, don't have to split cases for new timing chain (which I had to replace 😂), and the cam gear had a cover over it for easy access. All in all, an amazing video on a beautiful bike, and a lesson to yourself and viewers on what not to forget!

One day I will watch enough of these videos to feel comfortable buying a p.o.s dirt bike and break almost everything on my journey to throwing it away and buying a new dirt bike.

I love your channel! Absolute perfect work! Greetings from germany.

mano, parabens, video muito bom. eu não falo seu idoma de forma fluente mas entendi os cuidados que vc passo e o que fazer. sinta-se orgulhoso pelo seu trabalho.

I had a 91 RM80 when I was 12-13 years old. Thinking back, I don't remember changing the oil or adding any EVER. I ran the absolute shit out of that bike. I finally sold it when I was 19.

Bro this content is gold

Love your videos man and I wish I had my old xr100 to fully rebuild it!

I love the way u work with your dirt bike.I would also love if u made a really in depth video on a engine rebuild.I have a 2019 klx 140 and want to upgrade some parts.

Thank god ur soo good. I learnt soo much from you! Thanks🙌

Awesome information/tutorial on how to fix up a DirtBike engine system and also helpful explaining to us aswell. Awesome video once again. Cool and helpful guiding tutorial video.

I known the comments help... enjoyed this one. Thanks!

I was hoping for a yoshi or poweroll cam. (not even sure if those companies are still around). Great video reminds me of my past life as a Honda bike mechanic in the 70s. Hey you may want to explain why the end gap is important. I use needle nose on the wrist pin clips. Put it on one edge, seat the other edge and gently roll them into place by rotating them toward the gap. You pay so much attention to detail it is incredible. Any person who gets you as there mechanic is darn lucky. Thanks for the memories. Larry

That was top notch brotha !! Good work on that top end. TDC Baby. !! That is a sweet little bike ! Love it

That is one beautiful looking bike!

Cam tastic job again thanks for your help and God bless you and your family

Having been in this situation at Glamis, my daughter ran out of oil on our TRX250 with a 650R engine. The drain plug backed out. The exhaust rocker arm and cam were toast. We added oil, rode it the rest of the weekend and upgraded the top end when we returned home. Honda's rock

And for the valve retainer clips, i like to put a blob of grease on the valve stem, so when i put the clips in place, they dont move around when releasing the pressure of the tool. So you dont have to fiddle with a screwdriver etc whilst holding the spring compression tool.

Nice video Cam!

Great info. Thanks Cam

Great instructional video!

Bore, stroke, hot cam and inner rotor that thing.. she will ripppp. Hahaha And get Haley standing up while shes still new. You will thank me later. Good shit man, congrats on the engagement!

did you use a different bolt on the cam chain tensioner hold down plate when you put the engine back together? It was soothing to watch an XR80 motor get rebuilt. brings back memories. Im looking to pick one up for some backyard fun.

Good job! Enjoyed watching thanks!

I love these pit bike builds

I love this engine video! Have you considered doing a video on a quad rebuild?

always killing the game!!🔥

Great video man!👌 The bikes mint now🔥

Very good n neat job dear full of skill keep it up

I did the exact same process on my ttr90 a few weeks ago. New piston, lapped the valves and cleaned them on my scotch brite wheel. But I didn't have a valve spring compressor......what a pain in my ASS. Only I remembered to put oil in it! Haha just busting your balls. Keep up the good work, I always look forward to your videos

Did the same exact thing on my pro circuit kx250f years back. Fresh rebuild on top and bottom. 269cc kit. Pro circuit head. Preoccupied and rushing, forgot the oil. Stuck the piston out on the heat cycle and it trashed everything including the cam journals on a $1000 head. I'll never make that mistake again.

We all make mistakes my friend but congratulations on your engagement.

Dude I’m new to your channel I absolutely love watching these builds you have such a gift!! Looking forward to maybe a CRF450 build!!

Fresher is always better🤙🏻 mistakes happen keep up the good work cam

Not often I watch a 40 minute YT video all the way through but I learned a lot

Hey Cameron Sorry to hear that! But problems are opportunities for improvements, so thank you for yet another great video! Question : How would you suggest i restore the bike's axles? should i run them in a wire brush wheel before the PrymeMX© cleaning pad or should i only alternate between the two pads instead? Thanks for ALL your valuable help bro! Congrats on your engagement! 7 👍👍👍👍👍👍👍 thumbs up!

Keep it up. Diggin' your attention to detail. This video, LOVE you can own a mistake and correct. Keep leading by example!

my friend amazing video I have a xr 100 1995....I will like to disassembly low part engine....I learn a lot with you.....thanks hugs from Argentina.

Congrats man

Your good bro we all mess up sometimes. I had an engine off of a ttr 125 where I installed the cam chain tensioner incorrectly and it broke the cam gear off😂🤘🏼

When i did my first piston change, i dropped a circlip in the coolant passage hole :D. Luckily it didnt go too deep and i got it out with pliers. Second piston change i put paper in the hole.

It worked out good for us,,,we got to watch you do a rebuild lol. The new Sony looks great too 👍

Omg man I was laughing like crazy, we all make mistakes but also we learn from them, hey that's the price having a fiancé 😂 another top video man loved it, I'm in the middle of my own build yx 160 pitbike build waiting on parts kills your vibe been waiting 5 weeks for a crank case after they sent the wrong one out love the videos keep it up keep me inspired ❤

Cheers for the scotchbrite pads/wheel Cam they should do the job,Great video by the way. Cam i like to say congrates to you onyour health and getting engaged mate.

I've made much bigger mistakes with bikes.. believe me, LOL! (but in the end i've learned much more from my mistakes than my successes. ) Great vid again!

Very informative vid. Thx

if the adjusters are the same as my sister's CRF-100 I found the square head on the adjuster is the same size as a drywall screw. I drilled a pilot hole in a piece of wood dowel, screwed in the screw and it makes a handy tool for those.

You're not alone, man! I did the same damn thing like. In a hurry and ripped around for 5 min with no oil. Doh! Ooo nice camera!

I was surprised of how little damage was done to the engine.

I've been wanting to do a xr80 vintage race style build for a long time. After seeing pics of xr75s and what was done to them, I wanted to see if I could do the same with an newer 80.

Thank you!!! Now there's a decent video on RU-vid how to take top end on crf80/100!!!

all the earlier xr 100 and 80 75 only had one valve seal if the guides wear they smoke like piston rings do

Man! They're not kidding when they say Hondas are built to last!

You are in pretty good spirits considering the mistake. You certainly have the ability to fix the mistake. Respect.

Scotchbrite the tip of the valves before you try and pull them out. Also theretainer groove can catch the stem seal and damage that super fine seal edge. Love the valve compressor. Where can i get one? Also do a figure 8 on the glass and sandpaper.

You make doing engine rebuild so easy 😂 just blew up my aprillia rs50 and I’ve had to take the hole engine apart even bottom end and I’m only just getting through it 😂😂

I have lapped valves manytimes u can do it how u did it BUT after lapping lapp the valve without lapping compuond and you should see some clear rings around the sealing surface and do it by hand

We have all had a major goof moment! Awesome video

Hey Cam, did you forget a dowel on the left side at 30:55? Just checkin bud, really been enjoying your content lately, keep it up!!

I don’t even own this bike but watching someone who knows what they are doing was great

Camron, in one of your videos did you use a powder coat of cerakote that didn't require to use an oven? I think i remember that but can't remember the video! Haha if so which video was it? Thanks
