I recently bought an 06 f7 and on the very first ride the bearings in the diamond drive exploded. I had a local repair shop replace the bearings and seals. On the second ride the secondary clutch locked up due to the shop not putting the three torx head screws in the end of it. Now on the third ride I find the headlight going out intermittently with the speedo also. I looked at the other threads here and checked the wire to the tail light and it looks fine. Please help!
