If you go the FmF TC-II route...be sure it comes with a mounting hardware package...grommets, sleeves and stuff. Seems it comes 'without' more often than 'with.' You can make your own 'kit' with various grommets and common sleeves, but it's a bit of a pain...both have to be 'modified' to fit and aren't as clean as the kit that comes from FmF.
I've had zero luck getting the hardware separately, and FmF ignored me when I tried to get it from them.
If you buy it from a local shop/store...don't walk out the door OR pay for it until you see that it's a complete package.
imo and all.......
Oh...you realize the oem S/A never needs to be repacked or really even cleaned, right? And an aftermarket S/A needs to be repacked AND cleaned quite often.
Well...a lot of guys don't do it often. Those are the louder bikes that don't run so good. A clean, newly (properly) repacked S/A is quieter and makes more power than one that is clogged up and not maintained.
