I can email you some pics if you give me an email address, and I will also get you the serial number. We are selling because we were building a grudge atv with this motor but then we got side tracked with financial situations and never finished and we have parted out almost everything except for this motor and a few other little things. The motor has a head shim for the turbo. And im not sure of who did the motor work. We bought this motor outta of massachutes so I am unsure.
