Spark Plugs

    I am replacing my spark plugs for the new season.

    My 1973 Tiger 750 calls for champion #N3 but I used a little hotter plug N4 for many years.

    The auto parts stores usually don't have the champions in stock.

    I used a NGK #BR7ES (5122) last year and they seemed to work o.k. but it is a resistor plug.

    I have heard not to use Resistor Plugs.

    Anyway, which plugs do you recommend?

    I use Champion N4 myself.

    My local auto parts store (independent place, not a chain) is happy to order them for me by the box.

    Or you can get them online.

    Also try your local small engine or lawnmower shop. I bought a few at my local Home Depot
