Hi all, I have installed a set of good secondhand gears by Paul Gast which have been undercut on the up shift side only for drag purposes I imagine and it shifts great going up but coming down it sticks like crazy but I noticed when I am riding in top gear and watch the gear lever it rotates downwards about 1/2" and then it is really hard to change down you have to keep chopping at it till it changes a gear then it's alright again until you get in to top again or the rotation happens whichever comes first,it was put together by a guy who you all know and respect so I don't know what's wrong anyone ever had this problem??Cheers Hooter.
