I decided to try out the Autolite 3923 spark plugs gapped @ .032, they are available at Wally World for $3.00, but need to be gapped to BMW spec, so I figured what the heck. I saved the Bosch plugs that were in there just in case.
I used the onboard toolkit with the spark plug adapter, the spark plug puller tool was not in the kit, but I carefully used my fingers to pull the plug caps off each side. Another item missing from my toolkit is the drift that fits with the spark plug puller tool.
Missing spark plug cap puller, and drift for sparkplug puller tool.
I installed the Autolites, screwed them in, then 1/2 turn to seat them. 1/4 turn from now on.
We will see on the next test drive if there is any improvement.
Condition of the spark plugs in the bike looked ok.
