Does somebody knows intake and exhaust valve diameter on my FLHTCUSE2 110 stock heads?

2.080" intake (5/16" stem)
1.625" exhaust (5/16" stem)

Donnie is making this a real project.  Keep the people on the edge of their toilet seats reading, waiting for the next issue when he really, really tells you what's wrong.  Although, he tells you what it could be and then disproves it.
For Example:
The 110" motor is the only motor with ACRs.  Let's see if the ACRs are causing the problem.  Blah, blah ,blah.  No it can't be the ACRs because both front and rear cylinders have ACRs and only the rears leak.  You can replace "ACR" with any other part of the motorcycle and write another paragraph or two.

How many issues is Donnie going to take this?? He is milking the hell out of this one. How many articles is he into on this 110 issue,, is it number 4 going onto #5. This is getting worse then who shot JR. I just got my renewal notice for AI, and i don't think I'm going to write the check this time.

It was quoted at the beginning of article one that it'll be a five piece article.  So just one more to go.  Howmuch of the final solution do you think will be verbatim from the threads here?  My bet is 90% with the other 10% making u all go...  (Tim Allen "Arrr?!?!?" sound effect please).

That's not much of a gamble, more like a sure thing.

Let's see, so far he has mused that it might be this, that, and everything but a full moon.  As the suspense builds, we see he is finally homing in on the real villain and is about to pounce.  Tune in again next month to see if Donnie can tame the Harley cheap-chit dragons and create a bulletproof 110.  I'm bettin' he turns that engine sideways to get equal air flow to both cylinders.  Of course, Moto Guzzi will then sue him for infringement.  This could turn into one of those neverending daytime drama's if he plays his cards right.

Hey I like that.  Then we could put a driveshaft... Oh... never mind.

what exactly is a "spiney lock" cylinder?

I just finished reading the April 2009 issue, Donny Petersen's article on the 110" CVO.  I was disappointed with the first three articles. Much overkill in each.


Having recently purchased a 09 Roadglide CVO I was interested in Petersen's remedy to the problem(?) which I understand now will be brought out in the May issue.

Please bear in mind I'm an old guy and fuel injected Harleys are still pretty new to me. I feel a great deal more comfortable when starting my 99FXDX 107" with  S&S Super G.


However, in fairness to Mr. Petersen,I  think his description of the causes,  pages 191 - 193, particularly the air/fuel/ratio values and idle speeds during the startup and related text, was worth the cost of the magazine.

Spiney-lock is a method of casting the iron cylinder liner to the aluminum cylinder block so that there is a bond between the aluminum and iron sufficient to seal the interface and not allow differential movement between the two parts.  This method has been used successfully for years in auto engines (read 'water-cooled').  Generally, the difference in thermal expansion of aluminum to iron is 2:1.  The more the parts heat/cool from their solid cast temperature, the higher the stress at the interface.  This can be
The interesting thing about the AIM article is that while the 110 engine casting sample was noted to have a different spiney-lock-cast distance from the head gasket than the 96 engine, in no way was there separation along the length of the cylinder body.  So how could the top surface of the cylinder not be even with the top surface of the block?  Don't know, but Donny stated he did find a diff on the rear cylinder of the 110 in his article.

Someone on this thread remarked they knew only 2 folks who has >5K miles without the upgrade.  Don't know if they are including me, but, if not, make me #3.  I have a FLHTCUSE3 (08) with 10,300 miles and no symptoms/leaks yet.  I'm waiting for a symptom b4 I use my letter from the MOCO (received it in Aug 08, with the fancy book).  Not sure if I should be proactive or not - hate to open up a tight, good running motor.

Make me #4. 9,993 miles on a 08SERK. No problems and I dont baby it.  I guess I got luckey. Great Bike! wish it had a few more ponies.

Keep reading here and it will.

This man is a genius!  Let's see if I understand this right.  The big problem is excessive heat.  Gosh who would've thunk it?  The spiney lock feature to secure the cylinder liners do not go far enough to the top of the jug which lets them move enough to disturb the even mating service required for the mls gaskets to make a good seal. 

So we need to reduce the heat which can be done through a variety of methods - sert, pc, etc., to richen the fuel mixture.  And we can change cams too and maybe even change over to Axtel cylinders and use higher tensile strength cylinder studs.

Oh yeah, and we can add a fan and perhaps a colder spark plug in the rear cylinder.

And for all this valuable information we waited what - over a year.  Give me a break.

It's a hoot, aint it??  And, it's NOT over, Part VI is next month!!

I think you summed up the recommendations so far.

NOW, somebody is going to have to 'splain it to me how the hell a colder plug is going to cool the motor?!?!  Assuming it's not detonating to start with, it won't mean jack!
