Spiderman....we're golden dog 

After staying up till 2 last night searching and digging thru past posts about Dave Mackie headwork (got from you), throttle body work / HPI (got from Sadunbar), Woods directional roller lifters (Sadunbar and Dewey)......I'm further understanding what changes some folks make and why.  This is a NECESSARY process for me no matter what I'm dealing with.  I'm the type of person that has to understand things before I do anything, it's just my personality bro.  Here's an example.  5 years ago a Dell laptop crapped out on me, I wanted to get a computer but didn't know dick about them so I started reading.  I've built well over 50 since and could tell you all about 1000 dollar chips, best MB's for overclocking, dual and tri SLI, raid setups, air cooling versus watercooling, best watercooling blocks for CPU, North and South bridge, Mosfets, bla bla...bla...bla    I think it's actually a sickness, I've got 5 comps in the house and the one beside me is an 8k box that runs like a raped ape 

What I'm doing now is putting the pieces together and forming a picture in my mind about my ride and what makes her go.  I'm educating myself, and I appreciate any help I get.  I don't believe good decisions can ever be made without good information and I know I'm in the right place for the info.  It's just a matter of separating the wheat from the chaff, understanding some peoples preferences and why, some folks brand loyalties, and the simple truth that's there's always more than one way to go that will achieve similar results.  Weighing out cost of course along the way and diminishing returns weather we're talking about performance gains or reliability, bang for buck.  Once I fully understand what things SHOULD be done, and after that what COULD be done, I'll have a pretty good idea of what I'd LIKE to have done.  Thats when I'll sit down with a well respected wrench and put it all in his hands, it's just not my way to be ignorant at that point in time.

There's one thing I won't do however and that is critique a member's list of modifications as that tells me he's already been talking to folks and probably has his mind made up and is basically looking for some sort of group blessing.

I don't understand this part though, talk among friends about ideas, paths, proposals, is great part of what forums are about IMHO.  A person might not have is mind made up, he simply might be trying to formulate it and is seeking advice from those he respects for their advice and opinions.  Yours on Dave Mackie was a great one, very impressed with what I've read

Not trying to offend... just offering my take on it.

What you want is performance, reliability, drivability, and fuel mileage, right?

Starting wil a CVO 110" motor, it's going to get expensive. You would probably be ahead on cost and the results you get by replacing the motor entirely.

[Steve Cole]

Depending on what you want it's going to be hard to beat the new 120R price for a complete motor. They can be had for $4200- 4400 out there and it's a complete motor. Time will tell if they really hold up as well as some of the aftermarket builds but looking at cost versus what you get it's a good start and you get to keep you old motor to boot. I've purchased one for myself to replace my 103 with but just could not leave it alone so I am adding a timken along with true and weld the crankshaft as it's only going to cost me about 300 more since I do my own work. Lots of options to be had and all I can add is to make your mind up and put it in one persons hands and let them do it. Dean in Vancouver BC or Jim at Metal Dragon are both good choices

Don't think for a second I haven't thought about a 120R =) .....not sure if you meant that route as well Half_Crazy.....and I agree, it's still way to early to know much about longevity.  But after the initial push back from folks, those that have gone this route seem satisfied.  My thoughts were, dump some money in this 110....improve the areas the MOCO fell flat on....with that approach in mind go even farther....wake it up and make it solid.....then wait another year or so for the bugs to get worked out in the 120R and folks to dial them in....at that time switch motors and have a built 110 I can ponder what to do with all the while raising my wife's blood pressure

Questions....

Is step decking / spin dropping / resurfacing the same process ?

A 2011 CVO Street Glide has a SE Compensator ?

you are correct, but your dealer will not upgrade under warranty, they will say the stock ones are working fine. thats why the 2011's have the new SE compensators, go figure. and I have full access to the info

Is the only issue with the stock CVO pistons....piston to cylinder wall fit ?

Two more....any thoughts on this ?

Based upon the base circle of the Woods 555 cam, he recommended SE Perfect Fit pushrods +.030, because they are stronger, lighter, and he's seen slight wobble in adjustable pushrods at times when he's put them on the lathe.

Or this ?

If your going through all that work, you may as well get rid of the slop from the cam chains and switch to gear drive cams if your crank run out is ok.

Questions....

Is step decking / spin dropping / resurfacing the same process ?  All involve machining the head deck surface (the mounting face).  Each process has it's own intent.

Is the only issue with the stock CVO pistons....piston to cylinder wall fit ?  In my opinion, the issue is more with the cylinders than the pistons...  i.e. straight, round, sized properly and stability when at temperature.  Many have opted for Axtell cylinders...

ahh....kk....back to digging

If you go with the 120R you'll need to weld/beef-up the crank and have the heads gone over. Well worth it in the interest of longevity/realiability and you'll get better numbers too. Then there's the clutch, throttle bodies, injectors, tuner, pipes, air cleaner.... etc, etc. It's more than just buying the motor and popping it in. If you're gonna spend the money DO IT RIGHT.

Then again, you could do all that stuff to the 110... it depends on how much power you think you want and how much $$$ you are willing to part with.

Putting in the 120R ain't cheap, but you can sell your 110 for a couple of grand and make some of it back...

Only you can make these very personal decisions. I would suggest a whole lot of research, but asking other people how you should build your motor is kinda like asking them to pick you out a wife. You are the one who has to live with that choice every day.

Here is how it is done

And here is the finished product, this is a 103 LTD head destined for a 110 CVO

[Spiderman]

"decking" a cylinder head is machining the flat surface of the head so that it is closer to the top of the piston - - - a cheap way to bump up compression. I believe in theory, every .050 adds 1 to your compression level, so if you deck a head .50 you'd go from say 9.5/1 to 10/5/1  It's not really as simple as it sounds, because you have to have the clearance in your piston tops to be able to do it, but that's what the term means.  For the record, I did it once after limping home on a dead cylinder with a blown head gasket. We had to weld up the head anyway sooooooooooo. Engine ran like a raped ape for about 6 months and then pulled the studs out of the crankcase leading to more issues and - - - well that's another story

I'm with ya Half_Crazy....I remember reading a lot about the 120R when it first came out...the additional stuff needed and even a few price breakdowns.

Not really asking how to build my motor per say....well maybe in a way....just painting the picture as complete as I can on what people do at the different depths of modding a 110 for performance and reliability....and understanding the reasons why as well.  Relating it back to the wife thing....if I asked ten guys to pick me out a wife and tell me why he thinks his choice should be the one...one of them dudes is probably going to be speaking my language if you know what I mean LMAO....sorry...couldn't help that one

Cool pics Dewey, reminds me of the ones I seen at Mackies website

Same type of result then as going to the Cometic .030 gasket then, just a different amount of increased compression.  And I take it that's what Dewey refers to as better squish ?  I understand there's different reason for doing this...but I'm on the right page right ?

[Mr_Ed]

Ooops...sorry Don (Deweysheads)....just ran into your real name in a thread about gear drive cams.  Which by the way is off the list based on what I've read.
