Well the Harley's are just as bad to the point the shop is going to get to charge you for the broken stud that they broke when removing the header. Here is a tip from an old motor head, when cleaning the bike spray a small amount of PB rust buster on these, let set for 30 min then go ride. My theroy is this, it eats rust and when you temper bolts w/heat and an oil product it prevents rust looking ugly

Try it and let me know I have been doing this since the Money hawg daze trying to correct the old HD blues.
