OEM Piston Rod

I have the right-hand head and cylinder apart on my 2010 V7 Cafe to fix a head gasket leak and took a peek at the now partially exposed piston rod.

The rod appears to be an aftermarket part, but I've never seen an OEM V7 Cafe rod.

So, I'm asking the collective brain to help me determine whether it's OEM or aftermarket; see attached pic.

Based upon WHAT?
Based on what appears to be an "H" cross-section instead of the more commonly used "I" beam cross-section. You can just see the back side of the rod in the photo, which is flat and doesn't have the two ridges of an "I" beam constructed rod.

I thought I recognized the rod and I’m pretty sure I do.

It’s a Carrillo rod.

Also one other thing. The V11 Cafe Racer is a 2011 through 2016 model. Are you sure you have a 2010? Does you VIN prefix match the one listed on the Parts Fiche? If so, it’s a 2011.

Thank you Scott; great pics!

I have a 2010 V7 Cafe Classic that was set up for racing with rear sets and other stuff by the previous owner.

Here's what it looks like now.

2010 Cafe 's were Green and came w/option kit for frame mounted faring that came back to about mid tank. Not many ordered the kit cause of price. I mounted a few, not many. I thought the rods looked like Carrillo too but Scott got it 1st.
Not fast but they looked the part.
 
Jason, this is painful to see you post on this bike with all of the issues. Not surprising.
The bike started life as a Press bike and was loaned for a story and ignorantly modified. It was never intended to be raced. Yes, that’s a Carrillo rod. Rear sets are OEM Guzzi from the ‘11+ Racer as Scott shows above.
 
That Carillo rod design is just like the type of rod used in radial aircraft engines. Radial aircraft rods were works of art highly polished absolutely beautiful. I spent hours cleaning them up trying to make them look brand new. Very strong too, we got one engine in that had a catastrophic failure. A piston seized, the rod broke in half and punched a hole in the adjacent rod which continued to function.

Here it is when I first purchased it. The green tank was made from a hygroscopic material that caused it to swell. So I tossed it in the trash and bought the silver/black/red tank that you see in previous photos.

Seems Todd knows all about this bike but it was not a Racer from the factory. It’s been heavily modified.

No it wasn't a racer from the factory; it was a yellow/green Cafe Classic.

The original owner bought the bike new from Scooter Superstore of America in Jacksonville, FL. I bought it from the second owner who was buddies with the original purchaser. And according to the second owner the bike was shipped to a Guzzi performance shop in CA for modifications immediately after purchase.

However upon completion, the original owner didn't like the results, never rode it and it sat for over 10 years. Then at some point the owner was going through a divorce, so he sold the bike to his buddy. However, his buddy was in an automobile accident and injured his leg, making it difficult for him to shift the bike. So the bike with only 1,300 miles on the odometer was put up for sale on Cycle Trader and I purchased it.
