125-200cc New to me bike! cr125 2000

Well after supermoto wheels on the te511 I decided I still wanted a dirt bike, sold the dirt wheels and bought this rough around the edges cr125 from Motoxotica. I am a dirt noob most of my time has been spent on streetbikes/supermoto bikes.

Reason being I wanted the lightest bike I could get, and figured a 125 2 smoker was it, but also wanted it to be green sticker.

Well right away after sittin on it, it felt like a toy. I figure a 125cc 2 stroke is not going to be that powerful and probably something like a oversized pit bike anways. The forks look dainty, bars are tiny, axles are tiny. Seat is super thick and cushy.

Well what do you do when you buy a new bike? RIDE IT!

So yesterday I went to stonyford ohv and rode around.


I WAS WAY WRONG. THIS THING RIPS! IT is DEFINITELY not a toy.

It is in a word perfect for me!







Couple of questions real quick!


*Shifter got loose on my ride so I did the aluminum can trick and ran another tank of gas or so afterwards. Has not loosened up so how long might that hold? Seems good but im not sure. Hopefully a shifter is not 100$ like my 511!

*Any way to check if its really a 125? I have rode a few but this thing hauls like a 250 man it really really goes. Gearing is 13/50 is that close to stock?

*Does anyone make white plastics for these early bikes?

*Anything I should check with a older 2 stroke? Powervalve need cleaning? Silencer needs frequent packing?

It runs great! I LOVE it. I am going to be converting more towards enduro / woods type riding. I do not want to do motocross, not much on jumps, more into exploring!

Ha ha that's my old bike! Have fun . I traded in that bike and my WR300 to help bring down the price of my new Beta 300RR I bought from Dan. That's bike was originally bought in Nevada and ended up here in Nor Cal with no title. I got it titled in hopes of restoring it and making a 165 but I feel in love with that Beta so the Huskies had to go. Motoplastics usa makes white plastic. Have fun with the bike.

Wow, small world! I am just so happy to have a green sticker 2 stroke. I can ride whenever I want !

great bike but i dont think you can really call it an "early model"

2000 CR125.

So I tested the compression, I figure since it is a 2 stroke I should just kick it over as fast/hard as I could repetitively until the compression peaks right? Is this the correct procedure? I did it with the tank off but fuel still in the carb so fuel = oil so no need to oil the cylinder when checking?

I spoke to the previous owner he never did a top end but doing the method above it peaked at 180psi. Is this okay for a 125cc? It runs fantastically and rips like no other but seems like the plug is quite dark/rich. But it may have had too rich of premix or poor quality premix in it before.

At what psi should I think of replacing the rings/piston?

Also is there a service or workshop manual for a bike this old? I mainly interested in the parts on engine disassembly assembly and trouble shooting any electrical (for the future).

Thanks yall.

I think around 130 psi is a good time to do either rings or rings/piston. Usually check the exhaust port for signs of blowby.

I used to just do a complete top end every 50 hrs or so. I have a service manual for an 04 cr 125. They're basically identical, anything up to '08 the service procedures are the same.

Whenever I've dialed in the jetting on my husky's they always tend to read a little on the dark side. Spooge a bit but pull hard and almost never foul a plug.

Lets get started!

Yes that brown is rust from the bearings. Notchy very loose, and the races are worn front and rear, top and bottom



Lets keep momentum;






Probably last a good while like that....or breakoff and leave me dead/stranded. Ebay 66$ shipped for a used swinger with a slight dent.

2hours and 45 minutes later including 30 min of scrubbing...

Shes apart!


This was broken just sitting in the swingarm/shock linkage. Another might kill me point;



Anyone have a extra swingarm bolt? IT is where the shock linkage goes inside the swingarm. Is this a bolt I can get anywhere? I dont see any on ebay or any parts sites, so help me out!

Shock worked good but when I went to move the adjuster some springs and bearings shot out and it canted sideways......



Not sure how much to rebuild the shock likely more than I want to spend at this point...

Lots of those shocks for under $200 on ebay. I bet somebody like LTR could fix that broken adjuster for cheap, though.

I saw that bike on Motoxotica's website last week and though about buying it. I figured it didn't make sense to pay $500 to ship a $1k bike across the country though.

What's the aluminum can trick for the shifter? Make sure you don't wear out the splines on the trans shaft, that is harder to replace than the shifter!

I cutout a piece of soda can put it around the splines on the shifter, hammered the shifter on with a rock and my cresent wrench. shifted up as far as I could and got my low profile 8mm socket in there and wrenched the hell out of it.

Worked perfectly. the thin aluminum can takes up some of the hammered splines and makes it grab good.

Old school trick that works.

I bought it ONLY because it was green sticker. It is pretty beat, I was 50/50 on it, but when I kicked it and it fired up instantly I was sold. It runs very very very good for its age. I mean 180psi?!? I didnt think they came stock with that much! Unfortunately the loose and skittish feeling of the bike is likely due to the f-ed up bearings everywhere and the broken bolt in the shock. Rear wheels a warp 9, and it keeps getting loose on the axle. I am not sure whats going on there. But the shaft that connects the bearings inside the hub is not tight like usual, its "loose". I wonder if the back wheel bearings are not right for the warp 9 hub?

180 psi is pretty good....my 88 husqvarna had 225 psi when new and is down to 215 now..thought about rebuilding it but it still has good ring gap

Thanks for the input guys. Anyone got a extra swingarm linkage bolt lying around?

WOW is that a ims 3.4 gallon?? Bike looks great, can i get the graphics in red/black?
