front sprocket removal ?
Posted: Tue Nov 27, 2007 6:59 am
My Electric 1/2" drive Impact attempting the c/s nut the "first" time
it was removed, all I could hear was the impact hammering away and
that nut giggling at it.
Easier to have somebody on the bike basically standing on the rear
brake, and use a cheaper pipe for the factory installed
(read:overtorqued) nut.
