2022-06-16 Spark Plug Readings and Carbs Sync Test

2022-06-16

Spark Plug Readings using BP8ES not BP6ES plugs (colder)

Plugs came back looking lean

So installed colder plugs, rode 100+ miles.

Here's the results.

The numbering is wrong. Really 4, 5, 6. These look much much better than before...

The entire set, electrodes left. 1,2,3,5 look a tad to black.

Electrodes right.

!, 2, 3 inlet ports. Pretty good.

4,5,6 not as good but didn't want to mess with sync... running out of time.

Need to get the spec's from FSM...

I discovered one can adjust the pilot jets and slightly change the 'balance'.

I tuned by ear and for max vacuum on the stix. These are the results.

Video to follow.
