110"/117" Bolt On Kits

[98fxstc]

We tore a kit down that had 7000 miles on it because of a little weeping around the base and the cylinders looked fine with no unusual wear marks. replaced the base o-rings and he was back on the road.

Curious about this Wes
was there anything to indicate why the quad rings were leaking ?
have you seen this before ?
Thanks

We see it once in a great while even on the 103" motors just replaced all the gaskets and it has been fine ever since.

Thanks
I have a small weep at the base of the cylinder on my 110
follows a rebuild about 18 months ago when I replaced the o rings
Wondering if there is anything extra I can do to make sure I get a seal at the o rings

Would the 110 kit work on an 08 softail?

yes it would...

What year is your 110?

[FSG]

you can buy the kit part# 92500039 it comes with cylinders,pistons and most of the gaskets.

The early years of 110 cyls had some issues of getting oil between the liner and the aluminium through porous spots in the drain back passage.

I guess 09 is early ?
Was all good up until 2 months ago
I'll try to get a handle on it when I disassemble

Thanks Joe

This has probably already been asked, but can you get 10.5 pistons for the 110 cylinders?

From who?

I have them in mine. I have the harley screaming eagle 10.5 dome pistons. They are in the Screaming eagle catalog

your running those pistons in a 110" bolt on kit or your 110" CVO? there is a difference in the two.... 

[woodreaux]

Can HD 4"  pistons 22502-07B be used with the new 110 cylinders with  Mva heads ?

No they can't the skirts hit the engine cases on the non CVO models.

[Good_Apollo]

Maybe a dumb question, but I know TC88 and TC96/103 cylinders are supposed to be interchangeable.

Would this 110 kit bolt up to a TC88? I realize it would not yield 110ci because of the stroke.

[HD/Wrench]

The cylinders in fact would go on , however the issue is the kit will not be a 110 and the pistons would not work due to compression height. Its meant for a 4 .375 stroke not a 4.00 stroke, A few have made pistons though.. It would not be a huge deal it would make a 100 CI  .. And the cost involved would be higher ,.. you can just bore your cylinders and end up at 98 CI

I have an old110 kit. Had my 96" case bored and crank worked over. I assumed a 4" bore was a 4" bore and should work with the drop on kits. I could be wrong.

[woodreaux]

The reason I was asking about the 4" pistons fitting in the new 110 kits  is -  I read elsewhere that some folks were going to install the new 110 cylinders with the 110 MVA pistons and heads on a 103 Dyna.

From what Tattoo wrote it sounds like they won't get  far with their concept.

[HD/Wrench]

Ok so to be clear 

88  3.75 bore    X 4 inch
95  3.875 bore  X 4 inch
98  3.937 bore  X 4 inch

96   3.750 bore   X 4.375  stroke
103 3.875 bore   X 4 .375 stroke


So to have same bore but longer stroke the wrist pin location is moved upward in piston..  So if you bolt on the 110 kit the piston would be approx .375 inch in the hole.. It is a piston thing nothing more

I just added the 107" bore in your chart is all.

CVO  cases are  machiened for the CVO 110" cylinders the 96/103 cases are not thats why they have the thinner spigot on the new 110 bolt on kits. the skirts on the CVO 4.00" pistons are a little longer and would hit inside the 96/103 case.

If you click on the link that FSG posted in reply #54 and read the instruction sheet it clearly states "Do not use stock CVO pistons with the 4" Bolt-on Cylinders or interference occurs between the pistons and crankcase" We did some testing at the dealership as well and confirmed this in deed is true.

You'd really be 1/2 that.. or about 3/16..

[HD/Wrench]

It was to explain the pin location  in simple terms, and show the numbers .  Not be spot on hence the approx

[NHBagger]

What's the CR of the 110 kit using an .030"?
