Randy, I think the maintenance schedule calls for the plugs to be changed every 16,000 miles. I have followed the interval and I have gone 35,000 miles without changing them. I couldn't really tell a difference in performance or gas mileage. FWIW.

I changed mine at 20k. They visually looked good/clean, with just very slight wear. Could have gone longer for sure, but they're so inexpensive.
Couldn't tell a difference performance, smoothness, or gas-mileage wise with the new plugs. :shrug:
Changing them next when I have a major service done at 43k in the Fall.

Yes, change them. I did mine at 25K ish, and as a lot of folks said and will say, they looked fine, EXEPT, spark plugs work best with nice defined corners and edges. The diode and electrode were both rounded. They were in spec and no real damage to the untrained eye, but really they should have been changed sooner. They are cheap and easy to take care of. Oil change isn't much easier.

:agree:Same here on my '03.
A local Winger says he has almost 147K miles on his '02 OEM plugs. To each his own but for me around $15 and you doing it yourself which does not take long.

I was talking to others with trikes, we were talking about gas mileage. They said they were getting around 40 mpg, I been getting 32mpg at best. The wing got 40-42mpg when it was a 2 wheeler. The valves were last adjusted at 1000 miles.

spark plugs changing is preventative maintenance, but change them and use ngk iridium they are the best!!
the wing will get around 40 as a 2 wheeler dont know how it can get better or the same as a 3 wheeler, hauling the extra weight, unless the top end is made much lower but gearing, but get those out of specvalves checked, they get tighter with wear and they will burn if they get to far

My bike was getting 42 mpg and dropped to 32 so I changed the plugs and now I am at 38 mpg around town. Only had 11,400 miles but had been sitting up for a few years. Had 6200 when I bought it.

They were pulling your leg.32 mile a gal is normal for a trike.:nojoke:
I changed the plugs when I did the valve check since I remove them to make the engine easier to turn over.
The new plugs didn't make any difference in starting or mileage. I'm now due for the second valve check so I guess I'll order some plugs.

This looks far too complicated for the German engineers at Bosch!
( I changed mine to Bosch and others said it would not run good with Bosch. (another thread.))
