I have been slowly fixing up my FZ since I bought it. It has 37500 miles on it, so I know there is some work to be done. On to the next problem, on decelerating I get a single massive backfire. This is shotgun level loud, people freak out if they are next to me. This happens easier when cold (needs less time of decel) , but always happens when warm too (like coming off the highway). My next step is to do a TB sync which I have read might help. But I wanted to see if there is something else I should look into (besides buying a PC3). I just replaced my plugs and they appeared to indicate I'm running rich (they were decently black). This makes sense to me since I'm only getting low 30 mpg with all highway riding. I am 100% stock to the best of my knowledge. Really hoping to get this bike running near perfect, eventually.
