Just picked up a 2007 RM250 from a local here on craigslist; anybody who is familiar with the current bike market out here, let alone a final year 2-stroke won't believe that this thing lasted nearly 4 days. As soon as I saw it I know it was coming home with me, it can't have more than 25 hours on it.
I'm calling this an OEM + build because right now, my budget is going to be minimal for this. My girlfriend and I are saving for a home, so right now my life is split between working and selling all of my stuff lol.
My goal is to make this thing just a fun, simple moto machine as efficiently as possible that I can shred and have fun on. Right now it isn't idling and the choke won't stick up, so tomorrow I'm going to be tearing into the carb to clean it.
Plans to run the exhaust are a PC works pipe mated to a 304 silencer. Jetting specs will be those advised from Pro Circuit
Main 168
Pilot 48
Needle NECJ 3rd clip
But the real score came when I found the parts bin that the seller gave me, at the bottom of an old Home Depot plastic tub was a shiny piece of vinyl that caught my eye. It ended up being a complete NOS set of Makita graphics straight from One Industries, I could not believe what I had found.
It's folded over and needs some love, but they're never used, never put on, straight up the real deal.

Congrats man.. hang on to that RM! This is my '06 RM I just finished. Next to my '05 YZ that I rebuilt top to bottom over the summer.
1. Petcock backwards, petcock broken
2. Air filter missing the air cage
3. Spoke skinz kept the spokes looking incredible, I can't believe it lol
4. There was dirt in the airbox from the Bush administration
5. Right seat bolt decided to upgrade itself from an 8 to a 10.
Finally I tore into the carb, i've never worked with a keihin pwk that has the TPS, so I patiently started un-doing the wires and routing that allowed me to separate it from the intake and reeds.
And finally, the disgust was found deep within.
Can't imagine why it wasn't idling lol
Removed the off road tank and put it back to moto form, the frame is in incredible condition.
How it sits now, I will jet it when my RMATV orders and in the meantime, yank the PC pipe off to knock the rust off and blue up the welds
Overall, I'm very pleased with the condition that this bike is in. I look forward to getting my bars on and see this Suzuki turns for myself.
The petcock is actually normal positioned backwards, the zuks were like that for whatever reason.
What a score! That bike is a beauty! I’ve always wanted to get another RM
Great Bike! Love mine !
The only thing that has me bugging is that the choke doesn't seem to be working; it doesn't affect the idle RPMs at all, anybody have an idea?
Took her out for a quick put around the court I live in, only to find that the clutch walks when you pull it in and is pretty much useless in the current state. I'm gonna have to tear into it later this week and see if the plates are sticking together or if the basket is toast.
Other things that I found, the countershaft seal is toast which explains why there was barely any goddamn gear oil in it when I went to go change what was left of it.
Put a set of Pirelli MX32s on front and rear, unfortunately this led me to find that the rear rim has a crack in it. Oh well, better excuse for the inevitable yellow wheelset I suppose
Pit Row
Tomorrow I'm going to hit the PC pipe with some steel wool, scouring pads, and a light bit of dremel polishing. I also purchased my first propane torch so I'm gonna try and blue up the welds as well.
The muffler bearings are in good shape, so I won't have to replace them but the blinker fluid is looking a little tired.

Good luck on the house hunt too. Stressful & exciting!
BTW- How is your gf’s dad doing?
Anywho, in my jackoffery to re-install, i bent the hell out of the core, so I cut it short about .75 inches
Next was to rig my favorite cost savings, the sink strainer sparky (Hypothetically). HYPOTHETICALLY IF I went to ace to pick up a sink strainer that looks REMARKABLY similar to spark arrestor screens, cut the edge off and BAM let pressure/tension do the rest, it would be a $4 spark arrestor screen.
Bought a rivet gun, watched a quick youtube video, and bam popped her back in, not bad for my first time!
Not a great picture of it, but I spent about 30 mins just bluing up the welds today after spending an hour with the wire wheel brush and scraping 10 year old rust/dirt from all over the pipe. I gotta wear a mask next time I do that, I burned so much oil out of that pipe with the weld bluing I almost fainted.
I'm a bar swap, countershaft seal, and some grease away from ripping her soon!
Something is wrong here, either the previous owner used an incorrect front sprocket on the bike, my guess might be he used a YZ part? Or the 14T is taller than the 13T stock sprocket? But neither of these make any sense at all. My worst fear is that Suzuki designed it so you had to take the chain slider off to remove the front sprocket, but that is laughably bad engineering and even THEY wouldn't do that, right?
Last, in my mind, and the most likely guess it that the tolerance of the old slider got so warped over time that the rubber swelled and prevented the sprocket from coming off easily; either way both gotta go.
The only way to get the damn sprocket off was to pull the entire swingarm from the bike, one thing lead to another, and I found myself disassembling and greasing the entire linkage. I had 2 frozen bolts, grease, oil, and dirt that smelled like death, and used more pairs of nitrile gloves that i can count from lubing the back end of the bike up, what a day.
Learn this lesson vital, if somebody swears to you they "just greased the linkage and swingarm bearings", they are absolutely, 100% positively full of shit.
Also installed the frame grips I ordered from MotoTape; fitment is okaaayyy, but not enough for me to complain. Some quick trimming with a razor made it a lot better, but it seems their cuts miss parts of the bottom of the frame side on these bikes.
Oh well, at least the idle is crispy and the exhaust tone sounds remarkably better (To me at least) after the re-pack.

"trust me bro, I have way too much into this bike to let it go for that. Lots of new parts".
Me: Ok, what did you do?
"fresh top and bottom end with a few hours " (ya suuuuure)
"new rear fender and sprocket"
I can tell from the pictures they all need full drive train, probably all bearings, thing is probably ready to blow up
Anywho, carb lines have been ordered and float will be re-set to correct 6.5mm height. Other than re-installing the chain and swapping over my bars, it should be done after all of this.
Life has gotten in the way lately but I am aiming to ride it next weekend at either Hangtown or E-Street. Will post the GoPro vid of my first impression.
Win, the 14T sprocket was apparently what was preventing the older slider from coming off. A NOS 13T Pro Taper front sprocket (OEM size) went on without a hitch.
Loss 1
Acerbis chain slider was far, far out of tolerance for the mounting points, was not straight, didn't even have the final cuts made from the production line for the mounting bolts to go through. Piss poor quality control but hey, it's made in italy so what did i really expect.
Loss 2
I stripped the rear mounting screw for the chain slider trying to fit said out of tolerance chain slider onto the swingarm. I need to learn how to helicoil. I'm going to order an OEM slider now, i'm finished with Acerbis products. This is the 4th time i've ordered something made by them on Rocky that is absolute dog shit quality.
