Hi all,
Am doing a bottom end rebuild, truing crank, Timken case bearing, while at it would like to up the piston size a little using the
same 110 cylinders, 113 seems to be an option a lot are doing now, what would be the best pistons for the job bearing mind
my heads have been skimmed 30thou and I want to achieve 10 to 1 comp, also have been told by a couple of people over here
that the standard valve springs on the 110 cvo heads are a bit too much and it would be better to reduce the seat pressure a touch, anyone have any thoughts on this, would be grateful for any advice. Ride Safe.

113" is a good option with Mahle flat tops
The springs that will work are either Goodson (AV&V) HVS-6000S or HVS-6500S

I Would Agree With Don. Let Him Or Another Do Tor Heads. You'll Be Thankful.

Don, are the 6500S for higher lift cams?

Yes thats right. I have not tried to take a stock head and valves and do this install. I have been told they work fine out of the box. The 6000s has coil bind at 1.200 and the 6500S at 1.15. I do use these springs all the time however I can check the installed heights, measure the pressures, and check for coil bind. These heads have had the seats cut and stem protrusion changed from stock dimensions.

Thanks for the info Don, Would you happen to know the Harley Part number for the Pistons?

HD Street Performance · « **Reply #6 on:** January 11, 2015, 06:32:07 PM »

Harley does not offer these. I have them in stock.
