Does anyone know of a company that makes a big bore kit for the 700? I've heard there's a way to convert it to an 800(or somewhere close) but I haven't seen anything on an actual bbk.

 

600/700 are the forgotten engines as far as big bore kits. Even LA Sleeve doesn't show an option for the 700,but plenty on the 800/900 etc. Give Todd Kerby a call. He's from my neck of the woods and says he's changed the 700s to 800s. 2100 bucks if he does it.. As far as what you have to change he can tell you.He has an ebay listing. https://www.ebay.com/itm/Polaris-800...-/291625063401
