grinding the variator boss

[phatboy]

hey

i see others grinding the boss down to get more top end. i have questions about that

first does grinding the boss mean i get taller gears all the time, so should put in lighter weights so i don't lose bottom end

second so i don't mess up my boss if i grind too much or dont get it straight, wht if i used my old restricted boss with the shoulder on it, and ground off the shoulder. and how smooth does the shoulder have to be, when ground down, is it like a machined surface, if its not perfect will it still be ok?

thanks

You cant go to far down other wise it will not bold down tight you only need to take about 2 to 4 mm off.If you go to far the threds on the shaft will not bold in tight. I did mine my self with a dremal it needs to be as flat as you can get it. make sure the part you gind is faceing out when you put it back in.
