My other thread got a little blurry with 2 bikes.
After I crashed in my latest race and broke my foot, I sold my 250f and tought " ill start over with a 125 to just learn to haul ass on that" (or I'm waiting for the 18 crf )
Bought a 2006 cr 125 ridden by a girl for some years. And tore it down and got it at least decent to ride on.
Basically I started with this:
Didn't take so much pictures, but cleaned and rebuilt most of it:
Brand new 2007 cr 125 ohlins shock
Borrowed the rocs clamp from the other 125
Ohlins fork from my old 250
999 twinwalls (changed to fatbar with same bend, man these things vibrate!)
Wider pegs
39mm pwk airstriker carb
Carbon reeds
Pro circuit pipe and shorty
13-53 gearing
Borrowed the seat (black diamonds) from my other bike
New linkage bearings
Laced up a excel rim to oem hub in the rear
Slapped in a new piston and clutch, set the squish to 1mm, hoped the Hotrod crank would do for at least 10-15 hrs. So I could get a feel if I wanted to ride 125 and refurbish the engine properly, or sell it.
Etc
Got it like this:
Got some riding done on it, and yeah, these things rip
Apparently, there's no engine braking in these so after I boiled the rear brake 2 times, I ordered some new hoses and 5.1 fluid, that I'm currently waiting for..
At 8.2hrs , last Sunday, I went to our home track, a bottomless sandpit.. got 15min in first moto and I grenaded the engine.. (luckily 50-60m before the tracks biggest jump) could have been worse.
Sooo, I currently got some parts from particles on its way with express shipping, all oem parts..
Piston
Cylinder
Head
Crank + bearings
And all the minor stuff.
800$ for 15min of fun
So this is where I'm at now, hoping to get the parts before the weekend, but I don't think so.. will tear it down this weekend, and hopefully get it running next week.

And I'm riding out at arlanda at the moment, just taking a break between motos, you will have to let me know when you are up in Stockholm with your bike.
I'm working every week in stockholm, bromma. But we don't have a good place at this worksite to store my bike.. working in bromma and living in the city centre, don't have the nerves to store it in the van..
I'll let you know as soon I get an possibility to get the bike with me
I am a parts-dealer myself, so I get it from myself, have to pay for it private tough My distributors are Pse-parts and c.c-products, and a tire supplier from Gothenburg.
More "special" parts I am ordering from partzilla and eBay!
Turns out it is haha. Looks like a fun little track too!
The Shop
When I'm riding a lot I leave my bike in my van, locked up in my garage, sometimes for weeks at a time, my van is alarmed as well.
I never stressed about my bike getting stolen, but I would be devastated if my suspension got stolen
And you can get a ride on my rmz, to see what you think.
Got home from a work week today..
Found out that gearbox bearings need to be changed also, hoping I can get some tomorrow..
And crap
Tought I got everything in order, this one fell out.. i think it is a collar on the shift drum.. well, 10 years since I took a 2stroke apart, guess I'll look at some blueprints tonigt
Looking forward to see how this bike will turn out. You're doing the right thing by stacking up on 125's. One can never have enough of those bikes...
Talked to a friend today that had been at the same track this Wednesday, it was still other people talking in the pits about how I held this thing WFO for those 15 min
But it was a diamond in the rough for 1200$
Thanks, hopefully I keep this "as is"
Badd: that is nicely prepped!
Still waiting on the 2 gearbox bearings, hopefully I'll get them on Friday. I need to ride!
Installed the exhaust port and studs, measured piston gap and ring gap, spot on!
Also installed the crank bearings, waiting for the cases to cool and then I'll install seals and get the crank in the right side case.
Then I need my bearings..
Sounds better from the engine, so hopefully it will last more than 8hrs total
May go back to the track I broke it on this saturday, maybe I get 20 min this time?
I recently rebuilt the entire engine/transmission on my 05' CR125. I fabricated a custom tool so when the case halves were pressed onto the crank, only the inner crank bearing races took the pressure. I am OCD. You do nice work!
Went to Tibro yesterday, bike held up 1 hr at least
Going back to the soft sand track I broke it on right now
I adjusted the needle 1 clip richer before I fired it up after the rebuild, sparkplug looks good so I may keep it like this, although I feel maybe it's a little too rich.
Have some rattling from the clutch (I listen too much to these things ) so I have got a Hinson outer basket on order and new roller bearing for it
