Some cranks are press fit so you have to use a case splitter, otherwise you risk doing more damage than the tool costs. I'm not sure about your 125.
125M cranks aren't press fit, rubber mallet works just fine.

I've split a few 125's. clean the outside of the halves on the seam well. get the debris off with a wire brush or rag.
Take your time, be patient. Just keep working around with the rubber or plastic mallet. If you do not have one, use a piece or wood or another softer medium to place against the case and strike.
be patient and just keep working around. I've had cases split beautifully in a few cracks, and some seemed like they would never split (until they did)
haven't damaged one yet.
penetrating fluid around the bolt holes and stud points.
Did I mention, be patient.

Alright thanks for the tips! I’ll attempt at it one day this week
do you happen to have one of those duck foot steering wheel covers or a universal puller? some cases can be split using one of these by putting the center of the puller on the crank shaft and bolting the outer holes of the puller to the case. tapping around the case with a rubber mallet as you tighten it.
I HAVE gone that route before ^^^^^^^^^^^
I've even made a case splitting tool with heavy flat stock and bolts. they may have worked, but always gave me more anxiety in the process.
The cases are designed to fit tightly and snugly, and any forces you apply that might go beyond those descriptions always make me nervous.
As long as you don't take a torch too it though.........
DAM Shop -It's okay, I've gotten a lot worse than just a thumbs down before LOL.

No I don’t have any pullers haha also when I get case apart would it be okay to wash trans gears and crank with kerosene
ya I think kerosene is a good option its cleans and unlike some solvents will leave a bit of a film to protect from corrosion. just wear gloves and dispose of it properly
