I'm gonna guess that 81shovelhd! hasn't worked on one of the newer bikes without a fuel crossover hose on the tank, and doesn't know how easy it is...
On the dual plug shovel heads, the plugs were on each side of the head, and accessible without removing the fuel tank.
You're right!
I've never seen that set up.
Removing my dash, disconnecting crossover hose, petcock hose, unbolting both tanks, removing tanks then putting it all back together just to service plugs takes a bit more than a few minutes on my bike.
Your set up is a snap!
Nice motor btw!
it has to do with rust and corrosion around the plugs from water sitting down on there, there have been reports about aluminum head material coming out with the spark plugs, if that happens you have to replace/repair the heads.
How new of a manual? Here is a 17 touring manual..
Add: BTW, last I checked, autos aren't air cooled..
I just stated the facts that spark plug manufacturers use a sacrificial coating on the threads and they say do not use anti seize, and Harley Davidson also says clean and dry threads in the modern service manuals.
I spent 37 years in a jet engine research and development shop, and one of the things we hated to hear was "because that`s the way we have always done it".
Technology and materials constantly change.
