Tried to replace spark plugs...
I just got my 2002 VN750 3 weeks ago, and I'm currently making my way through all the maintenance, changing fluids, lubing splines, stator checks, etc.
I bought the NGK Iridium spark plugs, but when I went to change them out today turns out the previous owner had already put NGK Iridiums in there! It was a nice surprise, and makes me feel a lot more confident in the first owners maintenance!
(Splines were dry though... but i lubed them at 7800 miles)
