All

3 degrees celsius today( 37F), humidity 87%, sea level. I did as hylo recomended and ran the needle at the third clip pos. Ran great up til between 1/2-3/4 throttle, went very lean and the rpm's took off like a rocket. This with a 500main. I had to bump the pilot back to 35 because 32.5 was too lean. Will...

Yeah but thats what I had laying around. Been running the needle like that for 90hours and no problem. Just sold the 125 so now im on a 250sx.

Okey good to hear. Will do some testing in the snow

I've been ghoosting this thread since it started. Im from Sweden and people here just ride along with Bad jetting. Jetted my 125 -19 properly and people think its a 150, i shaved the head and put 1mm of squish too. 40:1 motul 800 with ron98/mon94 oxygenated fuel. HGS Pipe and silencer. PW 2 1/4turns in from fully turned out...

Okey thanks

Where in Sweden did you buy the scotchbrite stuff? I do also want to give my engines some factory look

Polish the engine with a scotch brite disc to give the engine a factory look

Engine mods actually came with the bike when I bought it, VHM Head( used a thicker basegasket to set the squish to 1mm, to prevent detonation), Vforce Reedcage, Procircuit exhaust(makes a little more overrev), jetting. Piston change every 20 hours, Pistonring 10 hours, crank bearings and rod 50 hours.. Be sure to change these items to prevent damaging more geardogs...

Cut ur sideplates like mine:D

I used a decal from the rmz sideplates(2012) and mounted on the rm sideplates, cut around it and it turned out like this

My bike

The forks will fit but the newer rmz has a bigger front axel so the rm250 wheel wont fit Don´t know about the springrate but you can use springs from the rm250 in the rmz250 fork
