Check Spark Plugs
Getting ready for my trip to Reno then Las Vegas , I changed all my oils to Red Line.
Then I thought what the heck, change my Spark Plugs:
7,000 miles cheap tune up $9.00 for stock HD plugs...
The Gap from factory was set at .30 - calls out for .38 - .43 geeezz
Any way new plugs set at .40 and yep, bike runs like it got some new tenny's :-)
Anyother cheap tune up tips ?

As far as plugs go be careful with aftermarket plugs that have irridium coatings the Ion Sensor (Knock Sensor) doesnt seem to care for these types of plugs.

Miles Plugs Wires
Bike only has 7,000 miles - HD had the wrong Gap settings - good thing I checked
Stock HD Plugs $3.49 each cheap tune up - could not spend the $15.00 for the SE, as I change out my plus to often away
Wires , my buddy went with the 8mm , he to did feel a diference , maybe the extra $ 20 is what he felt ?
Plug Gap .38 - .43 is called out in my 2009 manual -I was surprised

Plug gap
Believe it or not the plug gap does make a performance and mileage difference. Running this down the track at 9.20 in the quarter you notice anything that makes a difference.
