A few years ago our 2003 SX Viper blew up. After researching it, we found that with stock jetting, the vipers run too lean in the mid range. This is what caused the failure. While just trail riding, out of nowhere the sled just seized. So after tearing it down, we need to find a rebuilt crank or something. Can anybody lead me in a direction where I could find one and not break the bank? Thanks in advance
