YZ92 Big Bore Specifications:
Fits 2001-2017 YZ80 and YZ85
Product Description
Actual Displacement = 91.99cc
Engine Modifications Included:
Cylinder: Bore, Port, and Plate.
Head: Re-chamber to work with the Big Bore piston. 100 octane suggested for most conditions.
Parts: Wiseco Piston kit, top end bearing, top end gaskets.
Notes: This kit requires you to send us your cylinder and head for modification
So you seized your YZ85 and tore up the exhaust port or you blew a bottom end bearing and gouged the bore above the transfer ports. You got a couple options.
1) Chuck down $600+ for a bare cylinder from Yamaha.
2) Chuck down $320 to weld repair and re-plate your cylinder back to stock. Then add a top end kit for another $150 and that puts you at $470 and you still have not fixed the damage to the head.
3) Get a Max Power YZ92 big bore kit, fix it all, and get more power to boot.
No contest if you ask me.
