Spark plug question here:
I bought my 2003 V92C Classic Cruiser in November with 16K miles on the clock. It's now pushing 19K miles.
The other day I was at the Victory dealership in Huntsville and thought it's probably time to pick up some new spark plugs since I have no idea if they've ever been changed.
The manual calls for NGK CR7EB spark plugs, and these are what are in the bike now. Probably the originals.
Anyways, the parts guy at the dealership at first said he didn't have any plugs to fit my bike, but after consulting with another guy and clicking on the computer for a few minutes said the CR7EB has been superseded by the NGK CPR6EB-9. Okay, it's an 8-year-old bike, sounds reasonable, so I bought two of those for 17 bucks and change.
So this morning I go out to change the plugs and when I pulled the old ones (which looked okay visually BTW) and compared them to the new ones, the new plugs extend nearly a quarter inch deeper into the head.
Now I'm wondering if they sold me the wrong ones.
Does anybody know if the original spec'd plug has been replaced by this longer model? Bike is not running bad. And now I'm afraid to put them in until I find out for sure.
