will lean jetting foul plugs???????

2 posts in this topic

no fred lean jetting won't foul your plug.

a rich mixture causes the black deposits on your plug that eventually stop the spark going across to the little hook bit on the end.

it travels via the soot & muck from the middle core to the rest of the plug without actually having to 'arc' or 'jump'.

give the bike a good thrashing, THEN make any modifications as quick as poss because a warm bike will start easier. try to ride the bike hard. kill the engine while going quickly & freewheel to a stop.
