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.
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! 🤝
Thank you for sharing your story. That’s a big jump from a Chinese 300 to a race 450. Yes, they are very aggressive. Glad you took the time to do your own repairs. It’s not that difficult. Appreciate your comment.
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
Heard on another channel that the owner of loctite has a hand in trying to shut trails down in Colorado Been buying anything but that now Great vid Thank you for taking us along
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!!!!!🎉
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?
Thanks for your support and comment. I am a former auto mechanic and have always been good with my hands. Fell in love with bikes out of jealousy for my neighbor riding his little mini bike when I was 10. Bought a busted bike when I was 14 (Kawasaki KD100) and ripped into it not knowing what I was doing but got it running… Engines and bikes are all fairly similar so it’s not too hard jump form one to the other.
Start it up, bang it in gear and hold it wide open. No, I generally take it easy for about an hour, and then start pouring on the power. I exclusively use Rotella T4 in my machines and change it every 2 to 3 rides, depending on how long I ride. Oil always comes out, looking as good as it did going in.
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.
Thank you for your comment. There are a few reasons that this happens. First thing I would check is your valve clearances on your intake. If the clearances are too tight, the cam shaft will drag and not want to turn. If your clearances are good, then your cam or head journal is damaged and that is generally due to incorrectly torquing them. The caps are not sold separately because they are line bored with the head from the factory as a matched set. You could potentially purchase a used cam cap but no guarantee that’s going to fix your problem. The correct way to fix it would be to replace the head, but who wants to do that right? I will have a video coming out shortly that will demonstrate the procedure to repair this problem. Generally, what you need to do is get some layout fluid, also known as machinists fluid, coat the camshaft journal, and then let it dry. Next, you will install the camshaft and torque the cap down. Slightly rotate the camshaft and then when you take it all back apart again will show you where it is binding. Would use a special tool to lightly remove some material from that area on the cam cap or head. You must use caution because you can severely damage your head if done incorrectly. Hope this helps.
@restoroosterohv thanks for the quick response. My intake valve clearances are within spec. I found a set of caps for $40 not a bad shot. I do have some of that blue die that you have used that gets all over the place not sure if that would work. When I put my intake cap on and torque the bolts to spec It doesn't even budge. I did notice when looking at the intake from the front its the back bolts that create the problem. The two bolts infront that are on top of the bearing don't do anything, and the bearing turns very well. Hope to see this video soon because I am stuck here and nope definitely don't want to buy a new cylinder head. Your videos are excellent. Great information and it's given me the courage to dig into this. I'll try the caps only because it's a cheap solution but if it doesn't work I'll be looking forward to this video. Thanks again
@restoroosterohv also wondered if this is something that if I felt uncomfortable doing, would you do it for a fee also me paying shipping both ways. Maybe make the video with my cylinder head 🤷♂️. Thanks again for all the information.
@emmanuelgonzalez-jk7mk that is exactly what this video is from, a subscriber with the same problem. If the video doesn’t help, you could send it to me for the repairs. Contact me at restoroosterohv@gmail.com

Thank you. I will be doing a video soon about how to fix a dragging camshaft.

I love the Rotella! What’s your go to break in procedure?
Start it up, bang it in gear and hold it wide open. No, I generally take it easy for about an hour, and then start pouring on the power.
I exclusively use Rotella T4 in my machines and change it every 2 to 3 rides, depending on how long I ride. Oil always comes out, looking as good as it did going in.

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
@UP_YRS_NWO I have done all that but it leaks from running to long
@ the main clutch case
@UP_YRS_NWO I’m going to try rtv
