I'm looking at what I want to do for a 107 for my 2015 RG. I use the bike mostly over the road or weekend trips. My motor guy will punch the stock cylinders, 10.5 to 1 pistons and TW 777 cams. Pretty straight forward. We were talking about heads. I was thinking about getting a set of Fuel Moto's B grind heads.

I saw the Screaming Eagle MVA heads in the catalog (part number 16925-11). I'm wondering if anyone has used these and how they work. The catalog says they work on a 103, 110 and 113. However the intake valve is 2.120. That seems a little large since most moderate flowed heads seem to have an intake around 1.900.

I'm not predisposed to using HD parts but if its a good product I would consider it. Any information would be appreciated.

The chamber volume will drop your compression too low unless you have the correct Pistons. They are good heads for bigger builds.

That head can be machined to bring the chamber to a proper level, as will the intake surfaces at that point, but that head can strip the low-end torque.
Our Stage III Super-Tour Head (1.940" intake valve) works VERY WELL, on a touring 107". :)
