Dunno about a big bore kit $, wouldn't mind speccing up to a 690 Rallye!
Most of the rebuild parts are pretty expensive.
Prices is US Dollars only as a guide, prolly double them for NZ:
Piston $350, Rings??, Cylinder if unable to be recoated $450, Crankshaft complete with 2 bearings and conrod $650.
Oil pressure was fine, no loss of oil anywhere, just a few substandard (critical) bearings in pre 2003 LC4's were prone to early failure. KTM issued a workshop notice advising replacement of main roller bearing in particular.
God I love the internet, some very handy info out there......
