98 K1200 surge, rough idle
Stumbled upon this thread looking for info and thought I'd share.
20k on this engine, 45k on bike, bought new. Started surging around 3-4k constant throttle, slightly rough idle, quite low on power, sluggish throttle response.
Wanted to pull plugs to check em but stopped at the wires as I saw white oxidation as others have #1 wire to #3 metal tab. Further investigation saw #3 at bottom and #2 @ top. Slightly rerouted and restarted, rough idle gone.
Took it for a run and WOW! Where did all of this power come from! Smooth quick throttle response, gobs of power. Left it alone, we'll see how long this lasts.
I did try to get #3 wire off since it was easiest to get at, but it seemed impossible, even after twisting it. Anyone know the secret to removing these?
I'm thinking they'll need replacing soon enough so I'll have to revisit.
