    Thanks Silverrider, I wish it was that easy, but the dealers that I contacted could not help me. I can't locate them on the internet and thought that someone on this site may be able to help. It looks like we are running out of parts,

    Check Twin Motorcycles web site to find part number, then google it with part number.

    Thats what I do ^^^^^^

    You might have to get whole cylinder heads, but have you checked e-bay?

    Curious how many miles are on the S3?

    Thanks, TPEHAK googled it and it indicated parts for sportster 88-03,

    Do you or anyone else know if regular sportster valves work in buell heads?

    Thanks, you may have saved a Buell.

    The S3 has 21000 miles and my XB 1200 has 6000. What do you ride and how long have you been riding or is it to cold to ride anything where you live?
