2007 Sportsman 450 to 500

Hey guys. I've searched and still been unable to find the correct answers. I need to rebuild my 2007 450 and wanted to bump it up to a 500. I've seen the kits with piston and jug and gaskets and its not that bad. BUT I know the carb is different. Can the 450 carb be jetted to feed the 500 or will I need the 500 carb? I haven't been able to find this answer much less anyone else thats doing it. Sigh,

I hate making noob posts like this but I give up on search... If there's a website or other post that addresses this please help..

Thanks,

Jon

The 450 has the better carb, the Mikuni BST 34 vs the leaky drippy BST 40 on the 500. For the money you will spend, not much gain.

Thanks,
Will
