Will an 05 YZ 125 transmission fit into 06 YZ 125 engine?

Recommended Posts

I split the cases on my 06 yz 125 and found a bunch of gears with chipped teeth. Does anyone know what years are interchangeable or if an 05 transmission is the same as the 06? 


Photos below of chipped gears, should these be replaced for sure or could they be safe to run?

The only difference in the 05 and 06 motor is the '06 CDI has a 500 rpm higher rev limiter and minor porting spec changes that don't matter and in '07 got the upgraded shift stopper lever and it '08 the reed block the white plastic insert stuffer piece was changed to be alittle more wider/open.  Otherwise all other parts are the same in the motors.
