Never hear of the 32 in any CVO 110" motors. I wonder why that cam is so over looked. Noisey? Or just a better cam for the lighter bikes.  Thanks Doc

I tried a 32 in a 2009 CVO. Lazy bottom when compared to the 54. Didn't cross 100 TQ until 2900. Did make 106 HP with a stock non cat headpipe.
Was not a good choice IMO for a 110 with stock gearing.

GH and myself have the 32H in our 110". I applied based on Dewey's recommendation. I like the cam I have 25K miles on the cam but GH is on the fence. Andrews has told us to bump the compression to get the full impact of the cam. So I may send cylinders and have a set of pistons matched and bump compression. Also have the valve guides changed and refresh valves this winter.

You still think the 54 is best for a mostly stock 110 with nothing but no cat and good baffels?

For a big heavy Touring bike, the 54 is very hard to beat. They are cheap, quiet, use stock pushrods and springs.
And they consistantly produce very smooth round torque curves.
Heres a 107" with my X Pipe, 54s and stock heads. You will never see a smoother torque line anywhere.

Just to clarify. Do the  Cyclerama 575 cams bolt in using stock pushrods?

With no need to change head gaskets with this CR 575 cam it would be a lot cheaper to use ajustables.   Doc

Yeh, Doc, I'd rather buy adjustable's than pull the rocker covers if I don't have to for any other reason.
