Found this set of SE 103 heads for sale. Trying to find out more info. We're they for the 2006 CVO's or just SE heads for 2012 and up 103's etc. Seller has no part number or info. These are completely different heads from the 103+ heads which required matching 103+ pistons.
That's them, 16965-03a. Old style non beehive springs, different intake ports than newer bikes. Seller dodging my questions about part number, age, and what looks to be a disfigured digit for the year. I'm going to pass. Thanks!
from what I saw in the pics, at least one of the heads is an 02 casting date with a part number of 16965-03. IIRC that would make them the early 103 SE heads. Also IIRC nothing really special. If the seller is giving off bad vibes, its not a good sign. Its not like the part numbers arent CAST INTO THE HEADS or something........ its not that hard to be honest, and barring that, he could eat the damn things before I bought them
they are nothing special and the chambers are a lot bigger than regular 103 heads (from the couple sets we`ve seen here) your much better off just getting some regular 103 heads and porting those with 1.9/1.610 valves
Yeah, those CVO heads are a rare bird and it will cost too much to get them to work IMO. They actually flow pretty nice but the chambers are 92-94 CCs and don't have any squish. You could go with tapered squish pistons but then you'd just blow money on a non standard build. The guy wants too much for them. At $400, you'd be better off getting your heads done. 07 heads can match the flow easy with new valves and porting. The guys here are experts at this.
