ASK THE MXPERTS: (02/12/10)

Dear MXA,
    I have a 2005 RM-Z250 with a bad engine. Can I install a 125 or 250 two-stroke engine in it?

    Yes you can, but unless you are a skilled machinist and welder we think you should think twice. Service Honda makes special two-stroke-powered bikes built on modern four-stroke chassis (including KX250 and CR250 engines in four-stroke frames), but they specialize in CR500 and KX500 powered bikes.
