Anyone know what compression you end up with 22502-07B 10.5 compression pistons
The wet head is less cc than the air cooled head
I think
Any would be appreciated

 

I would talk with a builder, your stock cams are creating well over 200 crank case preasure , I the stock compression is low 9's. So if you increase compression with new pistons you need to change cams.

 

Thanks I know the cams are no good for what I want
I got new ones se259e also torn on the se585
Just trying to be sure because I believe I am going to have 10.7
Really want them because the dealer got such good results with those cams 255 in them
94hp and 1112 tq that a customer only wanted pistons
I know from the race car the ring combo and piston coating are doing a lot of less drag on assembly
PS I do most all of my work

 

why not go with a 113 kit fuel moto has a complete kit, they are getting like 120 plus torque.

 

my problem is I bought a new SE585 cam and while I was down the dealership they were showing me how much the compression increase power
So I taught I have it apart anyway get rid of the cast 9.2 pistons
But was concerned with the 10.5+ (not sure if wet heads are smaller chamber stock) causing me headaches with junk gas out there

 

well that makes sense, ask the dealer or call a tuner someone who does the porting of the heads, I think they are the same cc though.
Good luck

 

The 2016 110 in my Road Glide CVO Ultra is 9.2 to 1 and puts out 115 ft lbs of torque. My 12 RGC CVO is 10.12 to 1. It puts out 122 ft lbs torque. Those are HD certified numbers at the crank. The 12 Road Glide CVO was the most potent stock 110 that HD made.

It seems with the twin cooled HD went with lower compression to make a longer lasting engine. I put 87 octane from day one and it runs great on it. The others over the past few years were 115, 118 and 103 (Softail) ft lbs of torque. They some how came up with holding 115 ft lbs while lowering compression.

 

Thanks that's great infro
I am going to leave compression alone and put the se585 cams
not worth all the work when what I have is good enough
I am going to retire very soon plan to do a lot of riding
Shooting myself in the foot reading what you said
Thanks

 

The Rushmore wet heads have a higher compression ratio than the air cooled engines. The water cooling allows for the higher comp ratio by stabilizing the head temp.

 

The cvo 110 's are all the same .
They are all 95cc
The 103 wet head is almost 2 cr higher than their brother 103 air cooled
I guess that's why the compression is a sad 9.2on the cvo or Harley wanted us to buy their pistons
