Hey people.  New to the forum.  Sounds like this is a good place to chat on the CVO machines.  Glad I stumbled across it.

I have a 07 screaming eagle dyna  fxdse.  Love the looks of the bike, but have noticed severe vibrations from the motor and into the foot pegs and the rest of the bike when at about 2000 to 2700 rpm's.  I took out the 07 screaming eagle softail and it does not do this even though it is the same ci. motor. I have had mechanics at the dealer take out other 110 cvo machines othe than the dyna and they do not vibrate.  Anyone out there experiencing the same problem with their 07 fxdse?  Please come forth and let's chat.

Comments from anyone else are certainly welcome.

thanks

Sounds like it could be the crank runout issue.  Search this site for Tech Tip 324, TT324, early 110s had this issue.  Runout spec was upped to 12 thousandths from 3.  Mine was 20 and the motor was replaced.

Was it an early 2006 build, July, Aug, Sept?

[colcop]

I had similar on my Road King.
It ended when the crank sensor was smashed.  The bike has now been with the dealer
for a month.  Crank was out of true, but within limits according to Harley.
The cylinder liners were found to be scratched and there appeared to be oil starvation,
this was confirmed when the oil pump was found to be scarred.
Issue currently with Harley to deliberate on resolution as the bike is still under warranty.
My bike was registered in Jan 2007 and had only done 1000 miles.

Best of Luck........

IMHO CRANK RUNOUT!!!!!

It is funny with the new pressed crank Assembly's. They are supposed to be better than the bolted ones. Don't believe me, ask the MOCO. Yep the cheaper and less reliable assembly saves the MOCO mucho denero in assembly costs each year. We are the ones that suffer.

Hi rossmanorg   and welcome to greatest CVO site in the World.

Sounds like the guys have pinpointed your crank run out as the possible cause. best get the scoot down to the Dealers and get it checked out.

As always for a newbie we need pics of your scoot.

rossmanorg,

Now that everyone has gone directly to the biggest possible problem first, you need to remember to also check the little things.  Things like a defective mount, or a ground-out of part of the powertrain to the frame, or severe cylinder imbalance due to tuning, etc.   Sometimes we make the mistake of jumping ahead in the diagnostic process and blow right past a simple issue.

The vibration you describe is not normal.  Get it to the dealer, get it documented on paper,and if they don't find and fix it promptly you need to contact H-D directly to protect your interests.  Don't accept "that's normal" or "they all do that", since we all know that's BS.

Ah yes, the one little flaw in the logic those morons at H-D didn't count on when they decided to change the runout specs several times until the cheap crap parts they bought would be "in spec".  If the floppy crank was just mounted in a fixture and allowed to flop around, everything would be OK (until the bearings on the fixture failed).  But the idiots forgot that the crank runs in very close proximity to other engine parts, and that the right shaft turns the oil pump.  Can we say "cheap stupid bastards", boys and girls?

This has nothing to do with your vibration, but the softail you rode has a "B" motor in it and is mounted solid to the frame.  The "B" motors all have counterbalance shafts that are tuned to offset the weight of the crank and pistons.  My buddy has an '03 SE Deuce and I've ridden it quite a bit.  The bike is smooth at idle and at speed, not vibration transfer at all.  Your motor is rubber mounted and is allowed to move within the frame to isolate the vibration from the bike.

On my '08 SERK as long as I'm moving and have the clutch engaged, the bike feels very smooth, but if for whatever reason I pull in on the clutch, the bike will vibrate a lot.  I notice this more when coming to a stop light or stop sign and have pulled in the clutch.

Have you just installed new exhaust?  Have you added anything to the bike that is motor related?

Lots of guys here have complained about the front motor mounts breaking.

I think some of the more experienced guys here will be more help, but as someone else said, get it documented.  Are you now dealing with the same dealer that sold you the bike?  If so, I'm sure they are doing everything they can, but if it's not the selling dealership, sometimes they tend to not spend as much time with "nuisance" issues like rattles and vibration as they could.  Some will disagree with this statement as some "other" dealers have helped them where the selling dealer gave up or wouldn't try.  Warranty only pays when there is a problem that can be fixed.  If they spend hours and nothing come of it, no money for the mechanic or service department.  If they spend the two hours to find the problem, and lets say it's a motor mount, it may only pay 1/2 hour labor so the other time is not paid.

Things may have changed since I was a GM service manager for 15 years, but usually rattles etc are not reimbursed or not more then .2 of an hour.

Anyway now that I've rambled WAY too much, I'll shut up.

Dan you are correct the softail has a "B" motor and they are much smoother. They can't rev as high as an "A" motor but still very smooth.

With the vibration between 2k and 2700 it could be a motor mount but I doubt it. The motor mount will show you more signs at idle and take off. I am still leaning towards the crank. He just needs to get it to the dealer and get a paper trail started.

Wow! I,ve just read some of the 110 vibration posting and needledd to say I,m sick. I own a 2007 110 Screamin Eagle Road King with22k on it now. I,ve been thru the head gasket recall twice and so far it seems to be holding. Heres where I need some help from someone. After returning from a 5400 mile trip to Sturgis and back to So. Florida I took the bike in for the 20k service and 2 new tires and also another head gasket recall from HD. $1000 later I took the bike out and it had the worse vibration in the floorboards and handle bars I imediately took the bike back and raised all kinds of hell about someone not road testing this bike before the customer picked it up

Iworked 27 years in a Cadillac dealership and figured I had a bad tire broken belt or out of round. They rebalanced the wheels but the vibration was still there. Long story short they could find nothing wrong and I insisted they call Harley  The factory told them to do a runout on the flywheel and the cam. That checked out ok. They gave the bike back to me and I went on my merry way to a top independent in the area. I paid for a 2nd opinion and they felt the neck bearing was the cause of the vibration. Hd said the bearing was fine and I will pick the bike up today 7 weeks later still with a bad vibration. I am totally pissed off I agree with some  of the other postings I feel that Harley needs to step up and get this problem resolved whatever it takes up to and including new motors.  Thanks to everyone with your comments.

My SERK has a vibration through the floorboards right at 3000 rpm, on the way up and down the revs.  Fortunately that isn't a normal cruising rpm.  At idle the entire bike shakes, mirrors dance, handlebars bounce enough to make your head bobble.  Otherwise smooth.

Have you truly found out if this is motor or a drive train vibration?  If it vibrates in each gear at the same rpm, then you're probably looking at something in the motor etc.  If it is speed related, regardless of rpm or gear you're in, then it's probably wheel/tire/rotors etc.  I'm sure you've checked this out, but when Harley said check the crank, this only has to do with a rpm related vibration.

And yes, as DC said, idle and take off will show up a motor mount problem.  I remember back in the late '60s when Chevy had their bad motor mounts.  I had one go bad and man will the motor rock up to the right when you torque the motor.  In that case lots of times when the motor would rock up the solid carb linkage to the firewall would pull open the throttle to only increase the lift etc.

Redrocket, good luck with your quest for smoothness.... Smooth on....

Do you think a new copy of the same motor will be better?  My second is leaking others are on their third or fourth.

SKREMINEGUL07 you know normally I would be giving everyone CHIT about the 110. But in reality it is a problem that I am  not sure will ever get fixed in the 07's and early 08's. There were so many problems with the cranks and now as time goes on it just gets worse. The cylinders have been the step child since the motor was introduced. What is going to be next? Maybe nothing. We can only hope.

Hey gang, new to your forum but not to the forum writings, I am a road glide fan (two 06 Glides) and also a SE fan and could not get what I wanted from a factory stand point and built my own version of a SE Glide, could have gone back in years but wanted newer and late advanced components, that said I have dealt with the vibe issue first hand that seems to be a byproduct of the split crank, and all of your suggestions are correct and as I read them all I kept thinking was yep been there done that from, they have had my bike a month to motor mount upgrades, sensor, upper mounts, engine alignment, chassis alignment, tuning, ECU download in-download out I even got one motor mount from one dealer close to my house one Sunday and when I still had vibe the dealer close to where I work (easiest to work around schedule) checked the number and changed it again, same 1970's design just keep up grading (and that's ok) but they put that bike through it's paces and blamed everything but the crank and although it met the .012 on the measured (cam) side from one side to the other it was .009 on one side and .006 on the other for a total of .0015  and at that time it was still an 88" motor, when they handed me back the bike it was with reservation and you could hear it in their delivery, we want you to ride and see what you think, they had been on the phone with HD tech services and had a history by now, when they do this their given a number that will correspond to your bike and each time they call that number is where the trail starts and stops, I had to write Harley a letter to state my case because the bike was out of warranty by about 3 weeks but only had 4800 miles on the bike, they do not want or need bad press, they stepped up and made good on the crank when the dealer told them that if the bike was his he would sell it, I used this time to step up to a SE 103 package, but I said all that to say if It were not for the paper trail as suggested here in this post this would never come to be, so make sure your dealer is doing all they can do and if they contact HD tech services, get that number and keep your own historical data file, it will/might be the difference in you getting what you paid for to begin with or not, these things are a huge expense and we have the right to expect the best quality money buys! the only thing I wish I would have done while the bike was down was taken the crank from the dealer and had it balanced and let the install it then, and then I could ride and not wonder when I will have to deal with this again.
Speak Up! it's your money! You HAVE the Right!!
