Why is it that the owners of 07 & 08 110"'s can't get a definitive answer as to whether or not any parts have changed in the 09's and why there are less failures of the 09's?

AJ, good question.  Maybe I'll see if I can get the part numbers for the heads, cylinders, cams, etc., on the '09 and see if there is anything different from the 0905 'fix.'  Any parts other than these we should investigate?

Jerry, the only other thing that comes to mind it that they are now using a new exhaust system presumably to decrease heat. It would be nice to know what else is different in the engine. They have done pipes and ECM at the factory which is usually the first things people change.

I know why the 09s aren't having problems yet , no miles ! LOL

Most problems developed by about 5000 miles. We should know for sure by Spring.

Yup, it was about this time  in '07 we began to hear of issues with the rear cyl head gasket leaks.  With all the focus on this I would think if the '09s are going to have problems we should begin to hear of them very soon.

How about the crankshaft too?? At the moment I'm intensely interested in this subject...

Know of 2 over 10k and another turning 7.6k.  No warranty work other than maintenance.

Did some motor work to my '09 out of the box and checked runout at that time. .001  Have personal knowledge of another with engine mod done at 1000 miles and that one measured .001.  Two bikes are not much of a survey, but haven't heard of any crank issues thus far from the service departments with which I'm familiar.  I don't  have any reason to believe that there are "new" cranks with new part numbers in the '09, but suspect that manufacturing has been changed for closer tolerances as well as a different bearing supplier.
 
Time will tell, but I imagine when spring rolls around and the back yard builders get there "expert" mods on the road that we'll see some crank issues.

just hitting 500 miles on my 09, so far its all good... (LOL)

u cant ride them in europe if we havent got them yet.

The 09s hit the floor in Aug. YES ? weather starts to cool down. Wait till next July -Aug. and see what happens Hope all is well. I have a 07 that runs great, {except for bad valve seal} and can't complain ,BUT, I can't leave things alone. Working on 3 more patents now. If it wasn't for Gunsmoke , I could really get things done ! LOL

Are you inferring that the crank issues were caused by engine modification by non dealers.  My crank measured .020 and it was 100% factory except for oil.  Don't go there.

I don't have any "official" statistics from the MoCo warranty folks, but just from reading stuff here and elsewhere it appeared the crankshaft problems surfaced right from the git-go on the '07's, with some really major failures, then the severity of the issue started to decline.  Didn't read about many total failures later in the '07 and early in the '08 model years, but still saw reports of excessive runout when checks were performed.  Later in '08 the reports had tapered off significantly, and so far I haven't seen any reports on an '09.  The most likely scenario still remains a critical quality problem with their supplier that has been gradually addressed through process improvements rather than redesign.  Remember, the 4.375" stroker crank was a low volume part only used in the 103's prior to the introduction of the TC96 in '07.  Now it is the only crank for all production, and this wouldn't be the first time a manufacturer mucked up when drastically increasing production of a part.

I suggest that H-D hire Howie to be the guy riding the bikes off the end of the assembly line.  If the crank survives that initial WOT launch, it will probably survive anything the rest of us would do to it.  If not, better to tear it up where they have replacement engines sitting in the wings.

This may be the same business practice used on the 110 cylinders. With more 110's on the road as CVO's or kits the failure rate on the cylinders seems to have tapered off also. The part number for the cylinders remains the same so the vendor may have been taken to task to make the necessary corrections. We can hope.

I heard (not from the pool boy) that in the early production of the 110" (mine was built first week of August) there was a manufacturing process problem where assembly lube was being applied before the press fit which is not good.  Apparently no one could read Chinese.  From the members here, it seems like all reported were from the very first motors built.
