I'm gonna have a 883 to 1200 conv. done next month with the std.conv. parts.Screamin eagle pistons and cylinders.A buddy asks me if he where buying an 883 that the seller said was converted to 1200 if there is a way to tell just by looking at the bike/engine?I told em you could tell by riding it,but without riding the 883 first...So is there a way to tell just looking at it?They don't change the jugs on a std.conv.right?
