just curious my speedo quit working properly oh about 4 yrs ago it reads high...I disassembled the speedo and checked the cable it seems to be ok....is it a gear or a magnet in the front hub...I was thinking of ordering a drag specialties but I thought I would ask a few questions first.I had it out for its first run of the year and there seems to be a light rattle in the front hub...never noticed the sound last year...thanks
