My Schwinn has coaster brake and it didn't work good at all at first but I guess it needed broken in.
Tom's comment is not about a Schwinn bike, it is about their electronic speedometers ;-}
Personally I like analog speedometers like this.
~$25 at a bike store.
They are not as accurate as a dialed in digital they are a heck of a lot easier to read at a glance especially in bright sunlight.
Jim... an NGK BPR7HIX Iridium spark plug will give you way more of a performance boost than a copper plug wire, that is low on my list actually.
#1 is replacing the crap motor magneto to cdi wire with double insulated 16g and every 2-stroke I build gets that.
#2 is the Iridium plug which half the time I include free anyway, on all 2-stroke shifters anyway.
Do those first two and the plug wire is far less of a factor, kind of like using a thinner head gasket for a bit more compression or some other motor mod which wouldn't work as well without those 2 steps first anyway.
And YES! Put a front brake on! Riding any kind of motorized bike with just a coaster brake is a cheap preventable accident just waiting to happen.
