| Hi, think my injectors could do with a clean - sometimes getting occassional misfire / vibration coming through floor boards, nothing drastic though. Can they be cleaned using an additive or is the only way to take them out and have them cleaned professionally - if so has anyone ever done this - any help most appreciated as it ain't in the manual! Thank you.

| You can indeed use an additive to clean the injectors. Follow the mix ratio printed on the additives label. |

| I've had good results from Sea Foam in my lawn tractor, aircraft engine, and other small engines. Haven't needed to use it in my current bikes/trike. Lots of guys on the oil forum use it regularly. |

The cause of your misfire/vibration is unlikely dirty injectors unless your Swing has a ton of miles on the engine. Most gasoline today has more than ample detergent in it to keep injectors clean.
Our injectors are old school; only 4 holes in the pintle to spray fuel. More modern designs use 10 or 12 hole injectors, spraying a much finer mist into the intake port. This finer mist evaporates better and leads to more complete combustion. The finer the holes, the more likely carbon deposits will clog them. My point is it's unlikely that our coarse 4 hole pintles would gum up.
I'd look at several things causing your symptoms.
If the engine misses under heavy load (rapid acceleration) the ignition system is likely to blame. Start with new spark plugs.
If the vibration occurs at low rpm under light load, as in taking off from a dead stop, look at drive belt and/or roller wear.

| Yeah, What BigBird said.
You can remove the right side floor skirt body panel. That will expose the ignition coil and wires. Give the works a good healthy spritz of WD-40. That will help purge any moisture from micro cracks in the coil and adjacent wires.
After the WD dries you can take the scoot out for a nice dry ride. And after everything is well warmed & dry you can return home & give the works a good spritz of Silicone spray. That will seal those micro cracks from moisture and most likely resolve your problem.
Just why Honda decided to locate the ignition coil in such a vulnerable location is beyond me. Being there getting hammered by all the roadside potholes and soaked with all the puddles seems like a less-than-wise decision. |
