The throttle body screws (2) on my 2011 Forty-Eight keep coming loose. The first time, I didn't notice it until the bolts were both completely missing and it was fixed by the dealer under extended warranty. This time, I still have one of the bolts but I noticed that there was an o-ring between the TB and the manifold. Does anybody know how I can find the part number for this o-ring or the size so I can get one elsewhere? I also need to replace at least one intake manifold gasket that was torn while removing the manifold to get the remaining bolt out. Everything I'm seeing online looks like the seal isn't an o-ring but I definitely have a groove in the TB for the ring and a flat flange on the manifold for it to seal against.

Also, has anyone else had this problem? Is there a reason they don't use Locktite on these bolts?

Thanks.

The Parts Manual (and owner's manual and wiring diagrams) for your bike is also available from HD SIP site:

Use your VIN or the search in the top right, search for 2011 Sportster

 

Awesome!! Thank you.
