Not really. H-D uses a sequential port injection system.

 

After more digging, your right.

 

Then I guess don't use the Techron fuel injector cleaner but Techron fuel system cleaner?

 

I alternate between seafoam, Marvel's, and STP. Is there the posibility of using this stuff too much?

 

I don't use any cleaner, just try and stick to a quality fuel, that has a good additive package.

 

I follow the instructions and do what the manufacturer recommends

 

Since you ask. Think about it if you have ever cleaned a carb manually and what it takes to dissolve deposits. Will destroy o-rings and fuel socks at that level. At the level that is safe, doubt seriously it does anything. The only true way to clean injector would be to use an adapter in line. The only reason you should is you can see a drip after shut off inside throttle body. Any oxygen sensor late model bike compensates for any deposits.
