I don't know. course, I won't know anything till they get it all apart and let me know but they seemed quite confident that they had it figured out.
with any luck they will opt for the rebuild option and I can then get cams and maybe 110 cyls and pistons and save on the labor. that would be nice.

yep, if the dealer is paying the labor charge for tear down/rebuild, have the case bored for a 117, lefty bearing, and H-rods. if you dont want to bore 117, you will have a bulletproof 106/107 that will last 100,000+ miles

Just a thought. With a free floating connecting rod with a sleeve bearing. The piston pin to connecting rod maximum clearance is .002. The basic as new tolerance would be .0007-.0012 clearance. The maximum side to side clearance is .020 The side to side clearance should not be a critical issue here since it is actual a clearance value and as designed it should not be even hitting or rubbing on the side. However on my 04 with the square rebuildable connecting rods Harley does quote a new basic as built side to side tolerance of .005-.015 .
Not sure why Harley did not go to a no bushing end connecting rod when they went to the angle end connecting rods. What that means I think is a non floating pin in the connecting rod. It floats (has clearance) in the piston. All previous Harleys have a floating pin in the piston and connecting rod so disassembly can be done in the field with relative ease. With out a connecting rod bushing the pin would be a press fit in the rod. Nothing wrong with this and probably a better design then what Soft's has. However it will make it a lot more difficult for a garage mechanic to get it apart. Most all GM motors are non floating piston pins in the rod and system works great. However, you can get the rod off the crank unlike Harley were garage mechanic cannot.

So does the new press fit wrist pin design include snap rings in the piston or do we need to start worrying about wrist pins with low press sliding out of the rod ends and ripping up our cylinder walls?
I purchased a new '12 a year ago March, it was noisy, ran ok but always had some strange noises. Traded for a new '13 ANV in January and was asked by a friend if the bike was just like the old one. I told him the model and options were the same, color qwas different and for some reason....the new '13 is quieter in both the top end and the tranny or primary chaincase. I couldn't explain why because I didn't think anything changed. Maybe the noises I thought were in the chaincase and tranny were actually in the bottom end....

Normal case when the pin is a press fit in the connecting rod there will be no retainer rings in the piston. However I have see this where they did. Requires the pin to be located a lot closer when pressing to insure all lines up to get rings in the grooves. Forget what engine they went in but the piston, pin and rod came as an assembly. I pulled it down for a bad piston. Though I was just going to replace it till I went for the part. It was in a 300 cu-in 6 in a Ford truck as best I recall. Been 30+ years ago.

yeah thats wy I mentioned it, if they can't manage to keep enough press fit on the bronze bushed rod ends to keep them from spinning, why should I think they will have a good press fit onthe wrist pin and if it gets loose it slides to the wall without a snap ring or poly button.
Hard to beat those old 300 Ford and 292 Chevy 6's, those rods take some abuse, bottom ends are bullet proof. Got the 292 in my 63 truck, 15 yr old grandson just learned how to drive the manual shift 2 weeks ago. Good thing he had that torqy 292 to help him learn the clutch part although he did manage to kill it a couple times taking off on a hill...

I have the same noise issue as well. When I had it in for the 5000 mile service I was told the noise was not in the engine but in the primary. They did some re-torue's and stated the noise was gone. On my way to AZ Bike week the noise became louder. I have e-mailed the dealer about this post to see what they say. I will let you all know if I have the same issue and what the resolution is as soon as I find out.
