    You may be on to something ... would make sense. Maybe a spark advance issue also ... trying to think outside the box.

    Just sayin. But the engine is mechanically hooked to the rear wheels, if in fact the engine raises 1 to 200 rpm without a road speed change well there has to to be slippage in the drive train. My old suzuki intruder has a hydraulic clutch. When the relief port gets clogged with contamination corrosion from dirty fluid, then running on the highway would cause the fluid to expand because of the heat. When the fluid can't escape back to the reservoir it puts pressure on the clutch causing slippage. Perhaps you have a similar problem. It didn't take hardly any movement at the lever to disegage the clutch.

    Default RPM skip

    Running down the road at say 55 mph and in 5th gear. Engines doing 21 to 2200 rpm. Give it some gas rather then downshift and the engine skips a beat for a 100 to 200 rpm. Fells like its the clutch slipping. It only does this once in a while. Cant make the trike do it when I want it to. Does not do this in any other gear.

    FI miss maybe??

    28K on the bike. No engine services have been done yet. Other then regular oil changes.

    Its been doing this for the last say 2K miles or so.

    OEM plugs still look good burning right so is the gap.

    Any suggestions??

    Ive been using Aims oil JASO rated 10w-40 for the last 10K miles.

    I believe you said you are using Aims oil. Is it metric 4 cycle? If not the oil you are using will have friction modifiers that are not good for the wet clutch on a Gold Wing. Oil with friction modifiers will cause the clutch to slip.

    I ran the crap out of the bike. Gunning it at all speeds and gears.

    Then gave up and on the ride home 2100 rpm give it some gas to pass a car and it skipped a beat.

    Im almost 101% sure its an FI related deal.

    Might just be for those who are familiar with "Ghost Shifting" which my GW has also done in the past.

    Just one of those things Ill have to live with.

    Unless it becomes a more frequent "annoyance".

    Hondas do some strange things on their own occasionally. No rhyme or reason. Just is.
