Sorry guys, too busy at work today to get any measurements. I'm hoping to take some measurements and get some pictures of the two rods side by side. I also tried to get some pictures from inside the block but I can't get my camera maneuvered around where I need to get a good view. I'll keep at it though.
As for Kohler genuine or not...when I rebuilt this engine a few years ago, I got a "kit" from Stens. It had the correct std sized rod that ended up coming loose. The rods I am finding are coming in boxes marked "Kohler" and "Genuine Parts" with the blue and white K design I've seen for years. Unless someone is switching the parts, I believe them to be genuine.
As for whether its a closet K241, when I measured the bore on the block, it measured the specs matching a worn K301. Due to the amount of deep scratches I saw in the sidewall, I had it bored 10 over. If something wasn't right here, I would have caught it. I do not remember measuring the stroke at that time. I was more concerned about the walls.
Sorry I don't have pictures to show you yet. Hopefully tomorrow. Hope this information helps out.
