friend thanks excellent video. I have a question, how is the crankshaft sealing with respect to the clutch oil? since I can't see an oring in the bushing that makes the seal, only a retainer and the bushing on the crankshaft. Thank you, greetings from Medellín-Colombia.

Great job

Thanks for the video. I have a question. I purchased a 2005 yz450f and it came with a non oem carburetor. I wanted an oem one as a lot of people have problems with these jungle carbs as you say. I wasn't able to find a 2005 yz450f carburetor anywhere, but I found a 2003 yz450f and as per yamaha they are the same. My question is the non oem bowl has a leak jet but my oem keihn 2003 yz450f bowl does not have a place for a leak jet. Will this be a problem? Should I use the non oem bowl with the leak jet? Thanks in advance.

Would it not be a good idea to have adapters to fit on to either end of crank so you could take a reading furthest away from flywheels ? not picking faults as its a very good video.

Just found your channel and love your videos. I'm learning a lot! You seem to have an incredible amount of knowledge about these bikes. Did you have a formal education? If not, what did you find was the most valuable way to build your understanding of motorcycles across the brands?

Very meticulous, Work,love watching a mechanic do his thing.👍 nice victory dance 🕺

Great job I liked a lot of

Where did you buy your cylinder from?

Where you located I have to rebuild my 2015 engine that just get locked

Can't wait for the next video! Glad you saved this one and glad you are getting content back going!

Really like this episode. When I had recommended doing this bike, I never considered the EFI aspect. All the junk we work on is carb. You did dodge a bullet on that side of it. I've been getting my butt kick with another project. I'm gonna send a note tomorrow seeking your thoughts. This video gave me an eureka moment, I'd like to run that by you + 2 other things. Ken

Top notch content, thanks for putting it out!

I love the Rotella! What’s your go to break in procedure?

Great work! Currently doing a KX450..

it's alive! Great job as always

great video as usual, you really explained veey well eberything, including the critical process of torquing the cam caps if i've twisted one of them, the best solution is to sand the cap with fine sandpaper?? greetings from spain!!!!!🎉

nice

Awesome job as usual. Stick with it, man, please. TH-cam needs more guys with actual correct knowledge and information to put out. There are too many channels putting out crap info. From another mechanic, what you are doing is appreciated by many.

Godd day, i'm rebuilding my 2005 yz450f engine and have come across the problem where my intake cam shaft does not spin when the caps are toqued down to manufacturers' spec. Also, thanks for all the videos. I've gained a lot of knowledge watching you and also confidence to do it. How can I get my cam shafts to spin freely, or do I need to buy a new cap. My exhaust spins fine. Don't no what to do here. Thanks in advance.

You are a true legend! Let me share a story from my life: When I was 20, I bought my first ATV-a 125cc Chinese model. I enjoyed the bike and learned the basics, like changing the oil and doing minor maintenance. But eventually, I got bored with it and really wanted a dirt bike. So, I came up with an idea: I took the frame of a Chinese dirt bike and swapped in the engine. It worked, and everything was fine for a while. Then, I got tired of the 125cc and wanted something bigger and more powerful. I ended up getting another Chinese bike, this time with a 289cc engine. It worked well, but the frame was too heavy for me-it weighed 140 kg. That bike ended up breaking my right arm (dislocated it, actually). Since I couldn’t wheelie properly with that bike, I finally got my first real dirt bike: a Honda CRF450R from 2007. It was the most aggressive bike I’ve ever ridden! That bike could wheelie in every gear. Of course, I crashed many times, broke a bunch of bones, but I loved it! Later, I upgraded to a Honda CRF450R from 2016. That’s when my life really changed. However, I ran into a problem with the crankshaft rod bearing. Since my repair skills were still basic, I took it to a mechanic. Unfortunately, some mechanics aren’t honest. He told me I needed a new piston, oil pump, and other parts-which wasn’t true. I ended up paying €1500 for the rebuild. After all that, the bike still wasn’t running properly. The engine vibrated badly and just didn’t feel right, so I sold it. I was upfront with the buyer about the issues. Then came my first true rebuild: a Yamaha YZ450F from 2013. Once again, I had a crankshaft rod bearing issue. This time, I disassembled the entire engine, cleaned every part with gasoline until it looked brand new, and replaced the crankshaft myself. The bike ran perfectly after that, and it still does to this day. From that experience, I’ve learned so much about bikes. It’s impossible to put it all into words here. But if there’s one thing I’ve learned, it’s this: just try, and you’ll succeed! Thank you for your videos-I truly admire your professionalism! 🤝

I wish I could send you my 2019 kx250f and fix my oil like I have order new gas kit after gaskit to fix mine but it still leaks oil when I get hot

Nice video man commentary was all useful and on point. I'm hoping that slant and mx FCRs work more or less the same. I'm about to rebuild a slant and every youtube video depicts an mx😬

I believe you’re working on a 2014 model. That bike has launch control and the kx250f didn’t get launch control until 2014

Would you be willing to Mara video on aftermarket carb replacement and the difference in jetting specs ie. QAparts shows 135 Main jet. OEM calls for 182 on stock carb. I afraid it will damage the engine Thanks for any info FYI I’m your local fire medic

But u forgot to tell us how much that kit was? Which surprisesme. U musta known thats the #1question everyone wants answered.

My favourite chanel without doubt, you have my support from Spain! jejejje. I have a yzf 250 2008, Is it normal that my camshaft does not rotate smoothly and I have to use force to make it rotate? Should it rotate smoothly? This happens to me after adjusting the valves.

Just changed the pads on my 96 cr80 and now the rear caliper rubs the spokes. Why?

Man the best explanation is right here all these videos folk are making just looking and not saying nothing.

Hello, I have a kxf 250 2013, the injection does not want to start, the fuel pump is fine, the injector is good, the valves are ok, the compression is good but it does not want to start, are the temperature sensor and the one for the gear position related. Sorry for a long answer.

Hi! I came across your channel completely by accident, browsing through other creators. I would like to thank you very much for all your videos. I am starting to service my own motorcycle, and in the future I would like to do similar projects to yours. The knowledge you share is priceless for someone who wants to learn in this field, and you do it completely for free. Much respect for your work and good luck with your next projects. Best regards!

Great video I rebuilt a 05 yz250f Your info helped so much
