So, I buy a 2007 Streetglide a couple of years ago from a guy in Pittsburgh. I was told it was an upgraded 103 with a Stage II done on it. I'm provided with a stack of receipts showing the Stage II work amongst all of the other mods / maintenance. At the time it didn't dawn on me to look for the 103 pistons or jugs in any of the paperwork, since all of the other stuff was in order and it looked like the bike was well maintained.

Fast forward to the present. I decide to get compression release valves added to make it easier for my bike to start: my Uncle's shop is doing the work. I get a call from my Uncle asking why I have badging on the bike saying 103, when the pistons are both stock 96s? To say the least I'm floored. At least I do have the upgraded cams in there.

I guess this is a good lesson to learn about "Buyer Beware!" I'm a big fan of learning from my mistakes. Is there a way, without removing the heads, that I could have checked the internal work done on my motor? Besides markings on the exterior of the jugs.

 

The stroke on a 96 is the same as a 103ci. I know on the salt flats they have a way of measuring the bore without a tear down but I have no idea what the tool is called. It sucks the tool who sold you the bike wasnt honest about the displacement

 

Did you look the receipt over close? Is it possible the guy you got the bike from got ripped off by the motor builder?

 

Well that's exciting because now you get to do a 103/107 and your bike will run even better

 

the best way to do this is call the shop that did the work to see see if they really upgraded the engine. My buddy bought a 2008 ultra from a used bike shop in dallas. 103 engine badging. So he called the hd dealer in utah where supposed work was done. THey confirmed the upgrades to this bike via vin number.

 

If this did happen and you have the PO contact info, I would let him know his mechanic got him.

 

Thats kind of what I was thinking too. As least it runs good and was maintained well.

 

bum deal you got, but now you know what you have for sure

 

OK, in my ignorance, I thought stroked meant increased cylinder length, not the piston.

Beary

 

I while back I had called the shop that did the work. They could only guess based on what they would normally do, since the original owner got it done back in 2007-8 when he first bought the bike. At the time I called, I hadn't known the pistons were not changed, so my questions were more directed at what cams they used.

I am looking forward to the change in performance and knowing what exactly I have in the motor. It should be a great season to ride.
