I got mine back last week. Was in for 6 weeks. Basically have new motor. Only parts from old motor are oil pump and primary side and tranny. Went with new case's, forged crank, 113 pistons, cyl's,CNC Heads, 50 mm TB,am running on breakin map till Tues. Problem is still have vibration issue. Can this be caused by the only parts I didn't replace ?. Motor seems to run strong 1st & 2nd will pull front wheel at little over half throttle lf you hit it quickly. Any input would be welcome.

I was looking at the pic and noticed that one head has cnc ported and other has screamin eagle on it. Was wondering why both weren't changed?

Both were that's just HD

Both heads are the CNC Ported Harley just puts the CNC on front head , Screaming Eagle on rear head.

I've seen that before on a bike and wondered about it...thanks for clearing that up.

My oil was indeed leaking.  They changed out the gaskets and o rings.  It took 6 days to get it back.  Have driven 500 miles or so since then ....hopefully no more leaks.

Just an FYI Nov 22nd 2007

07 FXDSE 5,200 miles and a leaky Rear Cylinder... HD replaced both front and rear cylinders, both head gaskets, "O" Rings and piston rings.....  going in this Saturday to the dealer that I bought the bike from to talk about them checking the "crank-runout" so I don't hit the pavement

i have almost 7k and no issues yet but keeping eye out for oil leaks at head due to all i have been readn about and i bang gears hard .the bike will pull the wheel in 2nd at about 5 grand shift. sorry i dont have pics yet still tryn.if ya want to see it personally i would be glad to send ya on an email have alot

It's that same set of heads I've got Scott.  That's how HD badges them.  The rear head has the nice script.  They're apparently so damned proud of the fact that the heads get finished porting on a CNC machine that put a cheap-ass little plastic badge on the front head advising of that fact.  With fairing lowers and air cleaner on you don't really notice it on mine though.  Thank god....

    Read that and saw the username and thought Steve had sneaked out and bought a Harley.  Scared me for a minute .   Got the backwards username forwards for a minute and was just soooooo confused.

3200 miles noticed a leak at the seam of the case behind the rear jug. Took the bike in to have it looked at. Dealer (Destination Harley Tacoma) Contacted the motor co as to whether to break the engine down and replace the gasket , or clean it up , check torque on case bolts and run the bike with some dye in the case to see if the leak continues. They went with the dye route.
I had been wanting new pipes and probably against my better judgement decided to have the  that work done at the same time. New BR 2-1, Sert, and heavy breather installed.  94.5 hp, 117.5 torque on the dyno.
In the words of sblade, I hope it all stays together...................

Well, It finally happened. The dreaded rear head gasket leak. Small but none the less. I brought it to my dealership and they replace both front and rear gaskets along with grinding out the rockerboxes for clearance. I didn't even mention the latter .... they said since both heads were off it was a common problem with the 110's and they just did it.

The bottom line is I love my bike, the performance is great and they seam willing to fix what is wrong. I hope this is the end but if not ..... back it will go.

Most of the posts I have read have lead me to believe that the problem may be from inadequate cooling.
The leaks always seem to start at the rear jug where there would be a lot less airflow, and being that the 110's tend to run a lot hotter than the standard motors, Is it possible that with an oil cooler a lot of us wouldn't be having these problems? Or am I way off-base?
