You said to come watch so here I am. 63 yr old intends to build his ultimate lightweight motobike. As light as possible, as much power as possible. Your video gives me alot to now go off of thanks.
Very cool,i have been building 2t,s for over 30 years and your mechanic is excellent.You turned me on to some new music also that I put on my Spotify to listen to in shop working on bikes.

Finally, Rado, I'm an old man and I didn't think I'd live long enough to see it go together.

Tom, all the songs are from Michael Shynes he is less known artist but I really love his songs and they are not expensive to get for the videos. www.youtube.com/@michaelshynesmusic Yea, I feel you about Ukraine situation.. I used to live in Kiev for some time and still have a lot of friends there..

@@dirtniron Thanks for the info. I wish we could somehow wipe the scourge of the Soviets out of our lives or, at least, our countries. Seems Ukrainian president very brave man; hope he comes thru this alive. My mother is Polish and between Germany and Russia, they've really raised hell with Poland as well. Hope your friends OK. I was active in boxing and met one of the Klitschko brothers and also Lomachenko. I know Klitschko has gone back in-country to fight Russians.
Nice job! Motor looks awesome! Great video, as they always are!

Indeed. Except he's not wearing gloves. Repetitive contact with all those chemicals is a fast track to cancer. Plus he'll probably get much more frequent flus with his body having to express that crap out periodically.

Rado, No wonder you have so many subscribers!! Cup of coffee along with good music and tech build video was very mellow and enjoyable start of my day. I'm getting ready to ride and peel miles off my beast (Super Tenere) this morning. What a contrast to the 125!! LOL

Any tips on what it could be when your two stroke seizes while riding then the kickstart completely locks up? Ive took the head and cylinder off, piston and cylinder seem fine no seizure in the head but i have no idea where to look next😢
What is the oil you use to lube the cylinder and piston ?
Looking good Rado !! 😁👍

How do I see what music was in this video?
I just picked up a shiny new '23 YZ125X and plan to install a Rekluse TorqDrive clutch pack asap. I understand replacing a worn clutch basket but is there any performance advantage to an aftermarket basket over a stock one at this point? Was there any particular reason for your choice of a Wiseco basket over the Rekluse? Inquiring minds need to know.
@dirtniron
Жыл бұрын
hi, I would get full rekluse setup but they dont make basket for my old 2001 YZ125. The clutch pack is really good, more durable and stronger than stock, plus it comes with those metal sleeves so it actually protects your stock basket and it lasts much longer. My old basket was notched out badly. Wiseco was one of few companies who made tough billet basket for my bike, plus they have great quality stuff so I got their basket. I think you are fine with stock basket and rekluse torqDrive clutch pack, unless you are going to really abuse that clutch so maybe better upgrade to billet one. Rekluse has super durable clutch for "abusers" that comes with everything, checkout this video for good info about their stuff kzread.info/dash/bejne/X2d1lrWyXdTSqcY.html

Dirt and "Iron"? I mean, yeah there's some iron in there among all the Aluminum, Magnesium, and various alloys made up of the two. Sure, a lotta internals like tranny shafts, gears, forks, shift drum/rotor and such are ferrous alloys... so yeah, there's some iron,... just questionable as to whether it's a sufficient amount to warrant a name/moniker. At any rate, it's obvious you've turned quite a few wrenches, and for more than a time or two,... you're sharp bro. You're good!
Really enjoy your vids....new sub!!! Question....I have a new 2023 KTM SX-F 350 and the manual calls for 10W-50 and I don't see that Rotella sells it. Can I use a different weight oil other than 10W-50?

@@dirtniron So, what weights are acceptable to run in the new SX-F 350? I can run 10W-40 or 10W-50 or 15W-50 or 20W-50? I get confused regarding the weights. I just know the KTM manual says 10W-50. I assume it has to be synthetic, correct? I greatly appreciate all the help!!!

So so so much stuff remains unclear, skipped soooo many parts and important details. Thanks for the guide though, but this isn’t a good one. Any small details I had to google myself. Not that useful
This music so painful. Difficult make threw the video.
Probably a good video but I can’t get past the crap music.
