NB GSXR,
I like the clicky tail much more than the original. It feels right. I read somewhere that it takes like 20 minutes to install so, I was a little hesitant. If it takes others 20 minutes to do it usually takes me much longer. But, I was happy that it took about five minutes. It was just four screws out, old cap out, put washer in new cap, new cap in, four screws in and you're good to go. Could not have been easier.
I also like the ability to go straight to high mode from off. With the other cap, you could only use the ring and have to hit all the modes from low to high.
