Hi Guys

Just throwing a question out there to see if anyone can help. I bought a IDM .12 and it was meant to be hand modifed and run in as a part of the deal but when I got it had the Podified stamp on the cooling head. I raced the engine for a season and the thing was really good then it blew a rear bearing so when I pulled it apart to inspect the engine I noticed not a lot doing on the liner or crank.
I've attached a few pics to get your thoughts has this thing even been touched or modified or have I paid for something and got ripped off!!
