Engine builders, where can I buy oversize rod bearings? 98-01 R1

I'm putting together a little 600 4 stroke Ski doo snowmobile for my kids, I got it with a rod bearing failure, Ski Doo doesn't sell any oversize bearings but I've discovered that 98-01 R1's use the same rod/crank pin diameter, the problem is Yamaha's thickest bearing is the same thickness as the original, I'm hoping to find bearings that are .25mm oversize (thicker) and have the crank ground to fit. Any suggestion on where I can find something like this? I'm trying to avoid spending $1500 on a new crank.

 

Send the crank to Marine and they will return it like oem for $350-$500

 

Yeah, have it repaired. Sportbikes don't have bearings available in undercut sizes like cars do.
