I ordered the stuff to install the kit. Conventional wisdom from what I have read has been to avoid slipping gears in high rpm you should keep pressure on the shift lever until you let the clutch fully out and that keeps it from slipping back a gear. The only problem with a quick shifter is it's impossible. For one, the whole point is to not use the clutch and you can't hold the shift lever because it cuts the ignition.
I'm thinking that by installing it ahead of time, I shouldn't have much if any issues with gears slipping and keep the transmission dogs from getting rounded out.
Did you torque yours back on with an impact? Norton did a write up on the Ninja 400 and they recommended using an impact to remove the clutch nut and install it because you risk breaking the clutch basket with the holding tool while trying to torque the nut. I'm thinking to mark the nut and the shaft and then use a 1/2" impact to torque it right back on where it was before I took it off....
I know some people will gasp at the idea of using an impact on it but just guess what your local shop uses when you pay them all that money to work on your bike with love and care.
