QA asleep there

Had to dig up this old thread, got a set of 117 twin cam steel liner cylinder kits to install today and ended up with the exact finish like the one earlier in this thread. Dealer is going to warranty it. One completely normal cylinder and one with the tiny ridges from top to bottom and no hone.

Is it bored to size and just not honed or is is bored too big to be honed?

Just saw this thread for the first time.  And would hope that the OP had the issue resolved by now, for better or worse.

But in looking at the OPs photos, I think the second ring is upside down.  That's would be the start-middle-and end of the issue.

Size is correct, no hone at all to speak of, even the bore brush drags when you try to clean the cylinder, crazy chit. Top to bottom bad.

They may they have some trouble with boring over sized  then. I have to wonder if they are trying to bore right to the limit to save on hone time, now you have to wonder about the cylinders that are close enough to get a hone finish but did not have enough meat left in them to hone all the boring marks out. The hone finish will make it hard to see what is at the bottom of the hone pattern.

Is not and it would not damage the cylinder as shown if it were..

#2 ring is fine and not the issue. Lack of QA. A visual inspection by the installer would have caught this and should have been where the parts were returned

QA?

Quality assurance is a way of preventing mistakes or defects in manufactured products and avoiding problems when delivering solutions or services to customers; which ISO 9000 defines as "part of quality"

OK.

Anyone know who does the 110 kits for the MoCo?  Automatic 30 day delay when you order the high end 110 kit, makes me think that they do them after they are ordered.

UPDATE:  Service Manager has replaced the cyls, pistons, and heads under warranty.  Inspected the cam compartment and oil pump, reassembled and test rode the bike, delivered to my buddy.  Buddy went for ride today, seems ok.  Dealer said if it fails, bring it back and they will replace it again.
We will ride together and break it in and closely monitor oil consumption and any other oddity.  Then dyno.  It's running the same calibration file (SERT) that the dealer dynoed it with last year as a 103, but the cal has been modified to 110 in the displacement constant.

Way to go Moco and dealer on the quick turn  around and warranty.  Tore it down Friday, picked it up today at noon.

Well this is Good News, just hope the only time they have to go to the dealership is for the occasional service and not another rebuild (top end).
Kinda gives one a warm fuzzy they came up strong.

Except for me the warm fuzzy from that 2 year old quote goes away with this quote from
BVHOG this week that a different size kit with the same type liner has just showed up with the same defect so in two years they are still having the problem and who knows how often.

Seems like I have a set of the 110's in a box on a shelf that have never been opened. Guess I need to take a look at them huh.
