Just sold it! Too many projects. hate to let you guys down here but sometimes life has bigger & more fruitful opportunities that need watering. Good news is they are starting to pop up everywhere.
Charles dude! This is so sick! Your attention to detail is amazing, it’s always the little things that nobody will ever see, like all the work you did to the air box, that make a build complete. Having something done so well that nobody will ever notice it, is a great compliment.
Thanks Nick! I want the pieces to be good enough for other people to use once we actually have them in hand. I feel like most of these conversions are sort of one off creations that everyone has to reduplicate themselves every time. So it would be sweet if I could at least provide a couple of pieces like the ones in the video, and aluminum, that are just drop in ready for everyone. I appreciate the compliment and thank you for watching!
Came out to my shop to work on the bike and up popped the live stream for the Broke to Built contest. Then as it was kicking off, this one popped up for me so I couldn't resist coming over to watch. Once again Charles, another amazing build!!!
@@mxrevival I definitely did and I even managed to get some more work done on my bike as well!!! Work tomorrow for alittle bit, play with my toddler for hours then back to finishing up a few minor details on the bike before cleaning up the shop in prep to rebuild the motor!!!! Hope your having a great weekend too.
Looking good Charles. I use the same stuff to seal my airboxes. However, it comes in black too and that's what I use. I'm looking forward to your next AF video. Cheers! PS: personally, I would go with longer studs, not a thinner plate.
Love this build! I am a big fan of the yellow bikes and would love to do one of these builds and I was wondering if all RMZ250s had the high wishbone in the frame or just certain year models? Awesome channel, keep up the good work
Thanks for watching, Jon! Not all of the 254 strokes have the tall Y cradle. There are a number of reasons why I wanted to do one of these conversions to this specific bike, but this particular 250 4-stroke frame with a tall Y cradle was certainly one of them. Makes it a lot easier and less fabrication. Also, I already owned all the other parts except for the 250 frame to make it happen. You are going to want to use, if specifically for Suzuki, 2019 or newer 250 4 stroke frames if you want a tall Y cradle like this one. Otherwise, if you come up on a good deal on an older suzuki, no big deal. It's just one more part of the fabrication process and there are kits online to do the conversion more easily. Sort of a cut, paste, and weld application for the Y cradle area.
Talk about tinking outside the air box...... 😜That'll defintely work, think aluminium wil be fine, but stanless 2mm would be indestructible, and would never bend that wil maybe compromise the seal. 👍👍👍
Haha! I'm thinking aluminum too. Stainless is actually a great idea if we need to go extra thin? Would be quite a bit stronger than the aluminum. I feel like it's an area that flexes quite a bit so may want the alloy to be a little more pliable? Honestly not sure, I'm just thinking out loud. Considering what the original parts are made out of and the way they are attached.... Regardless I like the stainless idea if I need to go super thin. That would really help get the studs all the way through without adding an extra modification. Great idea
Oh dude, you've got to spill the beans! If it's easier for you, you can shoot me photos here via email: charles@mxrevival.com and I'll make sure to share them on TH-cam if you think they're useful
Different airbox, but you can also ditch the gasket for the Yellow 3M in the video 💪 It'll never breach again! I do intend to have true kit pieces for the 18+ RMZ airbox when we finally nail it down well enough to be acceptable for sale to my riders 🙌
doesn't the Late model RM 250 engine share some of the same intake parts as the 99-22 YZ250? with air filter, cage, carb, and reed cage, being the same, I'm wondering if the corresponding boot sealing ring and alignment plate offer any beneficial differences in design. Also how much lighter is the modern AF chassis than the original steel framed chassis?
You are totally right, there are and they do. Pretty sure specifically the parts you mentioned on the intake side. As for the air boot portion, I'm not really sure if I'm following correctly, but they are so different in connection design that I believe the Yamaha would be very hard to graft, if it were even in the right landing location on the air box. A big issue I had with the RM250 air boot was that it was way, way too low and left a huge gap at the top. It wasn't even close to hitting the air box properly. Thankfully the RM 125 air boot puts things right on target. But the flat sealing end of the air boot on the Suzuki boot is really great for what I'm trying to do, where the Yamaha has that through design, where it protrudes into the airbox first, then gets spread open by the filter cage, followed by a plastic strip and locking ring that keep the cage into the boot, therefore disallowing it to pop back out of the box towards the engine. Yamaha has a much more reliable sealing design, but it would be much more difficult to nail down to the RMZ air box for the reasons mentioned. As for the weight, I'm honestly not sure and I'm not quite that far yet. The aluminum frame might even be heavier because it is bigger all the way around. I'm very interested to see the weight difference, and I will probably be able to ballpark that really well once I identify final spring rates. That should give me a good idea of how much weight the bike lost overall from starting as a 4-stroke. Then there are the rest of the components that are just in droves compared to the two-stroke stuff. The four-stroke engine, wiring harness, rectifier, EFI, and so many more parts disappear during the swap and they are all super heavy. The awesome little two-stroke just has that nice light and compact engine, carburetor, and a few basic wires. It's insane how much more complexity there is and component with the four stroke stuff! Cool comment and thank you for watching!
@@mxrevival Wow bro, thanks for taking the time to reply. Looking forward to seeing the weight savings. The only thing better than a two stroke is a lighter two stroke.
Yes, if you make it fit haha! That old saying "you can do anything you put your mind to" definitely applies in this case. I'd be willing to bet that one has been done also in the past.
Hey John, not at the moment. I have one of those over eager appetites, where I start too many things at once, some of which are not as important as the ones to pay the bills. But, I will finish this bike someday!
SUZUKI PARTS ARE EXPENSIVE BECAUSE SUZUKI IS NOT MAKING ALOT OF AFTERMARKET PARTS. THE ONES THAT ARE MAKING ALOT OF AFTERMARKET PARTS ARE HONDA AND YAMAHA. SO YOU KNOW HOW ITS WHEN DEMAND IS BIG FOR SUZUKI PARTS BUT THEIR ARE VERY LITTLE TO GO AROUND THE COMPANIES THAT HAVE LEFT OVER PIECES RAISE THE PRICE. SO SUZUKI OWNERS THAT CANT AFFORD THE PEICES ARE SELLING THEIR BIKES . THEY COULD SLL THEM BUT NOT EXPENSIVE OR GO WITH CUSTOM PEICES OR GET HONDA OR YAMAHA AND CUSTOMIZE YOUR OWN PIECES. THATS A SMALL GROUP THAT CAN DO THAT BECAUSE ITS EXPENSIVE OR HANG THE BIKES ON YOUR WALL AND REMINISE .AND YOU KNOW THAT IS NOT AN OPTION ITS JUST PLAIN SACRALIGOUS.
Hey hector take a chill pill amigos and the all capital letters mean your yelling your words...and Suzuki is one of the few Japanese manufacturers that offers so many OEM parts available through dealers eventhough they are more expensive, but available, for some reason the uppity ups at Suzuki feel the need to keep their older bikes running... That's from way up in the command chain...and Honda owns a 20 percentage in Suzuki...nearly nobody knows...too bad Suzuki just didn't keep the 125 and do like Yamaha and build one great bike and just release the same bike forever... They would sell every single bike and have a cult following like Yamaha does... Kawasaki same deal, another failure... Im holding on to still finding a low hour 07 Rm125, that bike is awesome... I missed one at a dealer in Jacksonville Florida a couple years ago pre Co, like brand new for 3k, went back next day after work and it's gone! Brappp
Have you finished this build yet? I'm still waiting to see the final result on the tracks 🤨🤔
Just sold it! Too many projects. hate to let you guys down here but sometimes life has bigger & more fruitful opportunities that need watering. Good news is they are starting to pop up everywhere.
Do you sell those plates for the the fuel tank and air box?

I can’t wait for you to get this thing running! I just got my 3DP rear brake clamp in the mail too!
Me too bro! Ok, that's badass!!
Love the work bench light setup. Creates a great ambiance
Thanks bro! Two Fositan light stands from Amazon. One of the coolest gifts I've received.

Hell yeah, William! I truly hope you enjoyed both! I appreciate your viewership and I hope you are having a great weekend 🔥

Great job Charlie, very clever solution for the air boot and fuel pump block off plate 🤟🏻
You should (and will) have a billion following!!! Love the channel!!
I'll keep striving brother! Thank you very very much
Damn!!! That bike is going to be super sick when it is done! This just makes me want to get a 3D printer even more...lol!
Omg that is so sick 🔥🔥🔥🔥🔥
Awesome work!
Thanks dude! Chipping away here & there...
Another Great example of how meticulous you are with your builds...I am sure this thing will be 🔥🔥🔥 when she is done.
Thank you Dave! I'll keep going down the rabbit hole....
Very Nice !! Grts from the netherlands!!
Massive thanks!
Sad to hear you no longer have the bike would be curious to see if the new owner ended up finishing it. I was planning on building one
Prototyping 💪🏼
Yeah boi!!
French boy love it
Hahaha, awesome! 😂
Fantastic build. Hopefully you well sell a kit once done ✅ 🙂
Thank you! I am certainly hoping to have at least a fair amount of the components ready for anyone else who would like to do this mod!

Shoot, you and I both! Moving sucks, so happy to start feeling normal and tinkering again. Thanks for watching

Scriber with a short 90 for the tight clearance holes. Hf 2 pack
Dude, cool information! Do you want to drop a link for everyone here that might need that? Thanks for watching!
Feel like a cheap whore even mentioning my secret trips to hf when you work around people that frequent the snap on truck.

@@mxrevival hell yeah👍grip it and rip it!!!! Can't wait to see that machine go, gotta love em rm's brother🤜🏻🤛🏻
i built an RM250AF in 2016, there is a better way to adapt the airbox....wish i could post some pictures for you as it would take to long to describe.

It’s been a while, so I don’t remember the exact reference in the video…. But I do know what I meant. Ha ha.
@@mxrevival classic 😂
Have you finished that conversion? Ultimate bike 😍
Will the expansion pipe fit without frame mods?
Nope
Recently replaced the foam on my '15 rmz 250, I wonder if this Josh fella would be willing to sell this mod?

How much do you charge to do a build?
Typical high-end customer Build is somewhere around $15,000 all said and done. (regular builds, maybe not na AF)
