I've no idea on this stuff but it sounds pretty good. It's in Holland
Ultra rare YZ490 LC JPX Cylinder KIT.

 Includes:
 - Cylinder/head/ new wiseco piston (2.0mm oversize, next piston probably needs new sleeve)
 - modified 40MM Mikuni carburator, to fit yz490 intake manifold and airbox boot.
 - Pro Circuit Works exhaust (modified KX500, mounting needs 2 small brackets welded on standard yz490 frame)
 - Ignition with lightning coil/rectifier,regulator and waterpump
 - Reed valve with boyesen reeds fitted

 The bike the kit was removed from had 1989 YZ250 seat / gas tank / shrouds and radiators fitted. The back end had WR500 '92 plastics. This combination looked awesome!

 1750 Euro for the complete kit OBO.
 Please ask for more information / pictures!
