I bought a pair of adjustable clutch and brake levers from another member of the forum and thought I should share my experience. I have an 02 America and when I went to install, the brake lever fit like a glove, but the clutch lever didn't fit at all. I am/was pretty sure these were Triumph parts, so I did a bit of mining on the bike bandit parts pages. I finally decided that replacing the clutch lever housing and pivot screw on my 02 with one from an 09 America might work.
I figured if I was wrong, I would only be out $30. So I got the parts and lo and behold, it worked. I still don't understand why the hole for the pivot pin on the clutch lever is so large, but the lever moves smoothly and is no more loose in the housing than the stock lever.
Just figured I'd pass this on.
