HD has released a 110 Stage II Pro kit.
It runs 10.5:1 pistons and a SE 260 cam. They also recommend the SE 50mm throttle body.
The heads in the kit are the stock CVO units so they must be somewhat confident of the flow rates and valve sizes.
I like the sounds of this kit EXCEPT the choice of cams. I feel the SE 260 is too much of an RPM cam for a touring bike.
I have the pistons in stock and a local guy is willing to "clean up" my heads but I am still unsure on the camshaft.....
As for going to the 113", I have not checked into this yet.
PS, I rode my 110" today for the first time with the Reinharts and hi flow breather. With the SE #84 map it ran REAL NICE!!!!
As soon as we have time, I will have the map massaged.
