i found an odd problem. i took my 600 out for its first 10 miles and heard a grinding sound and noticed that the take off was almost non existant. i got home to find my primary was loose so i torqued it back to 55 ftlbs and went again. within the next mile it happened again so i retorqued it. once again in the next mile it happened. the shop manual doesnt mention anything about loctite but would this affect the ftlbs if i applied it and if so what should it be torqued to?
