So, I have a 06 883c and I bought a Sundowner seat today for the trip up to the Blessing of the Bikes this weekend. My wife picked it up for me at the stealership and brought it home for I was working. Was all excited for the comfy ride and put it on and it doesn't seem to fit?! If I line up the rear screw hole in the fender the seat does not sit against the tank. Also, the bolt that sits underneath the seat doesn't "lock" into place if the screwhole is lined up. If I push it against the tank, the bolt locks, but the screwhole is like 2 inches off. I am having a hard time believing this to be correct. Any suggestions besides take it back to the stealer? I checked the part number on the HD website, and the product number on the box and on the seat itself...

 

I don't have that exact seat, but when I installed my new Mustang seat it did not line up on the seat post like the stock seat did. It actually isn't suppposed to fit that way, your just install the tounge and groove, push it forward a little, put in the rear screw and it's done. Perhaps your seat is also built like this? Just an idea. Hope this helps.

 

I'd say they sold you the wrong model (part number) seat.

 

That's what I thought, but the number on the box and the sticker on the seat say 51507-04. According to the harley website, that is the correct part number. I didn't know if it was just me or they screwed up

 

The 4.5 gallon Gas Tank on the '06 XL883C Custom Sportster uses a smaller Sundowner seat than one for a Sportster with a 3.3 gallon Gas Tank. If the seat is not properly placed on the post, with the tongue inside the bracket at the end of the Gas Tank, the rear seat bracket will not line up correctly.

 

Forgive my ignorance, but I thought there was only one option for gas tanks on the customs. I know there are two different sizes for the sportsters, but I thought only the peanut tank came on the Customs?!

 

You thought wrong. The 04up Custom is the one model that DOES NOT come with a peanut tank. The Custom has a 4.5 gal tank. The peanut tanks are 3.3 gal or smaller.

Just wondering, if you've ever filled your gas tank????

 

Yes, I have . Oh well. Long of the short, the dealer put the wrong part number on the seat.
