GL1800 Misses on Acceration

Post by CSI Guy »

On my last ride I noticed that I had a slight miss at idle while at a stop light. Didn't notice it while at highway speeds. During acceleration I noticed it was missing. Not terrible but enough to notice. Once I got to cruising I didn't notice it. While at stop light it did have a very minor miss. When I got home I noticed bottom exhaust pipe on both sides were sooty looking. Didn't notice that before. Any ideas on where to start? Thx

Without knowing mileage or maintenance history of your wing, my guess would be an ignition problem so I would troubleshoot in the following order:

Spark plugs> check for a crack in the porcelain, check gaps, check for proper heat range of plug, replace if over 15000 miles.
Plug Wires> check connection to plug, check for cracks or weathering etc., replace if questionable.
coil pack> check ohms in all three coil packs for consistency or refer to manual for coil testing.

Good Luck,
