Fanatic Trials Bike
I had some jetting issues on my Fanatic Trials 250 2 stroke air cooled motorcycle, I had to set the idle at higher rpm than usual.
Yesterday I simply fitted an E3 3.34 plug, under the suggestion of a great tuner( Mr. Jo Dallera) and the bike started running smoother, better throttle response at low rpm and easier start.
Thank you E3 spark plugs!
