 I Need some advice,, I have a friend that rides a 2011 CVO RGU ,, coming home from a road trip he started hearing a ticking noise in the engine . He has the Bike at the Harley Dealer and they told him , the exhaust valve is sticking on the rear head....They either want to replace the Head of Fix the old one ,,,, Which is the best thing to do Please add any other advice you think would be best...

if the ex valve stuck,it would be stuck.in 40 years of working on HD`s,ive never seen a "sticking" valve,that didn't seeze all the way and usually bend when it makes contact with the other valve or the piston,heard HD techs telling people about it enough times though.

George, did he say the shop actually took parts off and inspected them, or is this something the shop just told him based on hearing a noise?  Also, is this an ESP repair, or is he paying for this out of his pocket? 

Exhaust valves and guides have been a problem on the 110 engines since they were introduced, so it's possible they are right.  However, if they haven't actually done any real teardown and inspection, there are also several other possibilities.  Lifters are also on the short list of problem areas, especially on 2011 and 2012 model years. 

A new head with guides from Harley runs $495 MSRP.  One of the guys running a shop can give you a ballpark estimate to have the old head repaired.  If he decides on the repair route, and if he has a significant number of miles on the bike, I would have both heads done at the same time.

Jerry , the dealer has the heads off , the cost of the repair is out of pocket..

26000 Miles on the bike..Should he do both?

If the cost of the repair were coming out of my pocket I would check with a reputable builder about having both heads reworked.

I keep reading about beehive springs and AVV?? guides.

 Several members/vendors here have more knowledgeable opinions on what parts to put in the heads and hopefully some will offer guidance.

If it were mine George I would have both heads done with good aftermarket guides and seals, and complete valve jobs.  That is based on wanting both cylinders performing as close to the same as possible.  I compare it to only doing rings on one cylinder, unless you're talking a very low mileage engine.  The experts might want to chime in here and recommend some other parts that should be changed, like the umbrella seals for the breather system for instance

He may want to get an estimate to repair the heads, versus buying one new one, before he makes a decision.  He may also want to check on the shop to make sure he trusts them to do the work.

Wow,  I'm surprised this is still happining. I had the same thing happen way back in 08 on my 07 that I already paid just under $1800. to have my stock heads reworked.  The valve was stuck up about an inch or so. I watched the head worker smack it with a hammer on both ends before  it broke loose.

1800.00???!!! WOW!! your talking about 350.00 (here anyway) for 4 valves,4 guides,seals & a SERDI seatwork

[JKM]

I would without question sound out the head have good quality valves, guides and seals done (AV&V guides) done to both heads.  If the original lifters then I would go with S&S lifters and have them measure the crank run-out

GeorgW221,
I totally agree 1800.00 is absurd and well excessive in price.

If I were having the work done I would want to ensure the following methodology and process was taken before I would send them out to be worked on.

One option mention above and its a good one noted by others in this and many threads is: AV&V Guides which are $64.00-$80.00 depending on sourcing and 4 new HD Valves in matching pairs intake / exhaust are another $64.00-$80.00 and Seals are $6.50 a piece (Black Viton)    That is just parts, then you have the work that it takes. 

The work which does add up in time:
First disassemble head, bead blast, clean, heat heads, remove guides, chamfer guide bores, reheat heads, install proper size guides, size guides for proper valve fit, cut seats,  then you have to have CC the head, mill head to equalize combustion chamber volume, test and shim springs, clean heads and assemble.   And the biggest thing after the work is done and recorded is to receive all the information about what each of these items were set to and what parts were used to get you there.

Hope it turns out well.

The bitterness of poor quality remains long after the sweetness of low price is forgotten

Although I live in Florida the fellow that actually owns the bike is my cousin in Kentucky. I talked with him this morning and he wanted everyone who piped in on this to know he appreciates it. We talked it over and he wants to ship heads to Deland for repairs vs replace. Repairs are expected to be approx. half of replace (a set). I advised to never do one and he agreed so he will be shipping both.

Clean/prep, blast, 4 guides, 4 valves, 4 seals, with precision Goodson/Serdi valve job, springs checked, chambers cc'd/equalized, final clean/wash, assembled, is how we attend to that simple job here.

[prodrag1320]

defanatly not a complicated job for any well equipt shop

[HILLSIDECYCLE.COM]

Straightforward, daily, 5-6 day-a-week occurrence here, in T/C, Evo, Shovel, Evo XL, or Iron XL, and the occasional Sidevalve work.
5, 110" CVO bikes in here in the past 2 1/2 weeks........all but 1 had engine repairs.
Opp's,....forgot to share that prior........
