Hi all. I'm at my wits end. I am in the process of rebuilding my top end. Lost compression in a cylinder, so I decided to just rebuild both cylinders. My problem is I've received what seems like all wrong parts. Twice! each time different part numbers.
All parts are OEM Cfmoto. first i received cylinders, pistons, rings for a 23 950 H.O.
second i received pistons for a 23 Cforce 1000 (0jya-040001-00022) 1 correct cylinder which they sent 2 of the same(0jya-023100-10020)

the wrong cylinders on the first delivery are part numbers:
First cylinder mark B 0jy0-023100-10021
Second cylinder 0jy0-023200-10021)

everything i lookup on Cfmoto USA parts for either a piston or cylinder says no longer avaliable. Do any of these part numbers I gave cross over or supersede to my 21 950? does anyone know the correct part numbers?

thanks for any help. I really appriciate it

Wow..sounds like a mess. Who supplied these parts? I do know the ZForce 950 in the US is the same as the the Z Force 1000 everywhere else and that the engine design should be the same from inception to current. As to whether the CForce 1000 shares all the same parts...which it likely does...I am unsure. Corrections with CFM are made on the fly and do generate a new PN but they usually show a revision or superseded number in the parts list.   

Main Street Cycle. They had a top end kit listed on their website. They are being pretty good on trying to resolve it.
