I have a clapped out old style (slant) 39mm FCR. I am in need of a new style 41mm I have been searching around on ebay and am wondering if the 41mm fcr's from the KTM 450 sx will work. They seem to be the most common. here is a link of a well priced one. http://cgi.ebay.com/ebaymotors/KTM-450SX-Carb-carburetor-450-SX-2006-_W0QQcmdZViewItemQQhashZitem588e0fd2d4QQitemZ380340523732QQptZMotorcyclesQ5fPartsQ5fAccessories I searched around but couldnt find any answers. if they dont fit, what should i be looking for? Let me know! I need a new carb!
