Hey guys I have a 2021 cbr600rr and it has a crack that looks like a knife cut right behind the stator on the engine block. It does leak oil slowly and i was wondering if i could get to the inside of the part of the engine without taking the engine out but by taking the stator off? Because I have a buddy that can weld it I can attach some pictures, thanks

 

f you want to braze aluminium casing or casting you need to take the seals out and put the case in an oven and get it hot otherwise heat will flow away form the weld so fast the casing never get hot enough for the braze to flow to it. Grind the a chamfer on the edges where you are going to weld to make like a valley for the brazing to flow into and use some solvent to clean it well before welding.
