Don't plan on doing the boomba short shift? Since you'll have the shifter apart anyway for the bushings, thought maybe it would be a good opportunity.
And to be honest, mrtn, I hadn't even considered it. I thought the Boomba kit and mountune kit were equivalent, not complimentary mods. I get that they are installed in different places, but isn't the point of both to reduce travel? I've done that (with warranty coverage) by getting the mountune kit. I've raised the overall height by getting the taller, oval knob.
I didn't think I needed the Boomba kit, too. Adjustability is really cool, but I'm very happy with what mountune did with theirs.
