Honda Service manual calls for inspection every iv,000 and replacement every eight,000 (Which is just nuts IMO) merely that's what the manual calls for. I inspected and replaced mine at 26,000 miles. The wheel was still starting and running adept and fuel mileage hadn't gone downward but I have come up to replacing plugs and air cleaners every 25,000 miles on my Honda motorcycles out of habit/personal experience. Use your conscious equally your guide or exist safety and follow the manual's recommendation.

These are special plugs, very skinny, very long reach and with a special sealing washer, which we have discussed at length hither:

Tools needed:
Air hose with spray nozzel
Stock Honda spark plug wrench or Move Pro equivalent (what we are using here)
14 mm box end wrench
Spark plug gapping tool
4 Honda Spark plugs LMAR8A-9S Honda Office Number 31908-MGC-003

Beginning by putting the bike on the center stand. We started on the left side of the bike but that really is unimportant.

Get-go thing you need to practice is check the gap on the new plugs. Spec calls for .031-.035. Mine all came out of the box from the mill at .033. Nosotros re-gapped them to .031 to allow for wear downwards the road.

Take an air nozzel and spray the outside plug cavity to remove any debris. We don't want any of that falling into the spark plug hole once the plug is removed.

Take off the outside spark plug cap and slide spark plug tool over the plug. Remove using 14 mm box cease wrench. We also used a swivel head long handled ¼" drive ratchet since we had one bachelor, just ended up using both tools as was necessary.

Inspect removed plug. As you tin can see mine was still in good shape, had a nice tan color on the ceramic, but gap had opened up to .037 (every bit electode and ceramic wore over time). These could accept been wire brushed clean, gap reset to factory spec and reinstalled. Nonetheless equally per my practice after 25,000 miles I went with new plugs.

With exterior plug removed we had good access to the inside plug. Exist certain and stuff some wadded up newspaper towel into the outside spark plug pigsty and then nothing gets down in that cylinder, and again apply spray nozzle to blow out any debris from spark plug cavities. Remove spark plug cap from inside plug.

A note here, if y'all have large easily in that location is not a lot of room to work on the inside plug.

İmage

Utilize your spark plug wrench and 14mm box wrench to loosen and remove inside plug. The Motility Pro tool has a rubber gripper inside which makes plug removal and installation easier than the manufactory spark plug tool.

Install the rear spark plug. Torque spec is 12 ft lbs on a spark plug. We couldn't figure any fashion to get a measurement on this given the modest confines of the space to work in. So nosotros ran the plugs in until they touched then gave them a bit more than, snugging them upwards. Y'all certainly don't want to over tighten them and risk stripping the threads of the spark plug hole. Reinstall rear spark plug cap.
