hi, this might sound bit off, which way is the disc in? does the thick part face to the rear ?if you have changed ratio, and lengthened the rod and still hangs up, only place left is the fork or throw out bearing or the disc is in backwards. I assume you have a stock bellhousing ?can you look up in there? have someone push on pedal see how much it moves.also, did the disc slide easily on input splines?
