Hey guys I was riding my xr and she made a crunching kind of sound and died on me now has no spark at all, was thinking the magneto or coils but not sure witch one or what ever was hoping someone could shed some light.

4 stroke question? I will give it the old college try! LOL! Crunching sound, sounds serious, timing chain, alternator bearing failure, any thing crank shaft related, If you doubt your mechanical skills, take it to a qualified mechanic, good luck!
