    I modified my stock pipes by removing the first baffle and the end pipe. I am contemplating on whether to remove the second baffle with a chisel. If I do this will I have to rejet?

    Also, what is a exhaust reducing adaptor? I am going for a deep and loud sound, does this help?

    See page 9 here:

    It says that it is not recommended/required to rejet when installing a GAK and modifying the 1st or second baffle. So I'm wondering if you just have to open up the PMS a turn or so instead.

    No, it is not recommended to install a GAK unless you remove at least the 3rd baffle.

    No need to rejet. You should be good.

    I took off the end of my exhaust and was fine, the plugs fouled so I popped a new set in. I installed the GAK and rejetted to 3.5 turns pms, 127.5 main jets, stock pilots, and 2 shims on the needles. Most importantly sync the carbs after every mod. www.650ccnd.com is the site I used and its got pretty good info.
