Crankcase main bearing letters - doubting myself!

Fairly common to see different numbers on the crank Phil

Thanks Ken - I'll arrange for another £285 to be deposited in DS's back pocket then!

Big ends as well Ken - probably get away with not replacing the mains/big ends as slight wear only, pondered over replacing but as its apart.....
Good thing is inside really clean, top end is mint and centre selector has no wear. All bottom end bearing good. So putting mains/big ends/rings and hone/primary chain/cush drive rubber/starter clutch/ oil pump overall/oil switchcam chain/guides/seals/gaskets/clutch pushrod - thats expensive enough!
