I still use the stock antenna but have it turned around and run it under the fender and seat. I only bought a $3 plug to cover the hole and I had to bend the mounting bracket but it wasn't hard. My reception is good but I live in the city, as I get further away on trips I drop stations as I get out of range. I switch over to my ipod if I don't like whats on the radio or if I loose signal. Around town it's fine though.
Didn't they use to sell a "suppressor" or something that went in-line on the antenna cable to reduce engine static?
