So I'm 400 miles into my new Airsal on my Tomos, Estroil, 27 speed sprokit...the basics. Everything is running smooth...Idle, start up, just crusing.
When I reach top speed (which I've come to enjoy) there is this inconsistent popping or crackling noise coming from the motor somewhere. If I let off the throttle or start climbing a hill it goes away. But down a hill, high RPMs and it's a cracklin' and snappin' away.
Question being...Is this normal, or fimiliar, to any of you guys and gals. Thanks
