2014 sportsman 90

Hello, new to the forum. my son has a 2014 sportsman 90 that i need to rebuild the upper engine on it ( has close to 2,000 est hrs on it) however I am having trouble finding a rebuild kit for the 2014. i can find all day long rebuild kits for the 2004,2005,2006 models but no cross referencing to see if it will work for the ’14. my next step is to check the much higher cost through the local polaris dealer where I purchased the atv from. Any help would be greatly appreciated.

Thank you in advance. Joe
