So I received a YZ125 that somehow has a chunk of the left crankcase half missing at the rear where the swingarm pivot goes through. This may be a stupid question, but I just wanted to see if anyone has ever had an issue replacing only one case half? (ie: issues with bearing bores not lining up perfectly from batch to batch)
If the holes on each side are not line up perfectly you will destroy crank/crank bearings/transmission bearings and the cases again.
if you have the missing piece, just get it welded.
Yamaha sells case halves so he will be fine.
Plus I can assure you, if you buy both halves they are not coming “matched”, your getting two random parts.
The Shop
Engineering, Quality Assurance, and quality control should rank very high at any of the major brands I would think. i.e. I don’t think they are just hap hazardly producing individual case halves that don’t match up.
