Bought my new (used) lowrider in Dec. I live in chicago and had to wear my snowmoblile suit since it was 20 degrees outside to get it home. While sitting on the bike waiting for it to warm up, I got that burning flesh smell! no it was'nt me, it was the down feathers and nylon burning on my screamn eagle pipes! I was told I can never get burnt nylon off the pipes. Is that true? any tricks to clean my pipes?
