Does anyone know of a good Manual for a 04 predator 90 ? I have to do the top end and I dont even know what the standard bore size is. Any help would be cool thanks.

 

Std bore is 2.050 (52mm) You might price an over size piston kit from here.Dirt Cheap Yamaha & Polaris OEM Parts & Accessories – Cycle Parts Warehouse plus labor to bore and hone,but might be cheaper to do as many have and just get a new complete top end kit from ebay.http://www.ebay.com/itm/Top-End-Cylinder-Piston-Gasket-Kit-Set-2003-2004-2005-2006-Polaris-Predator-90-/121093987394?pt=Motors_ATV_Parts_Accessories&hash=item1c31c39c42&vxp=mtr
