About 3 years ago, I purchased an '81 Yamaha XJ550H- at the time of purchase, the PO said he thought it needed a carb rebuild. The bike would start easily and idled fine, but if you opened the throttle in a normal manner, it would stall nearly instantly. Much to the annoyance of my neighbors, I discovered that by repeatedly blipping the throttle, I could get the RPM's up without stalling it. In the mean time, the bike has been setting at the back of the garage, and this morning I had the great idea to check the direction of the fuel filter. According to the markings, it's installed backwards. Could this have been part/all of the cause of the stalling problem?
I realize this is a stupid question, but in my web search, I found answers ranging from "The engine will run as normal, but nearly all of the crap will make it past the filter into the engine" to "The filter will clog very quickly and could cause the engine to stall/not start."
P.S.- I also realize that I have committed one of the cardinal sins of motorcycle ownership by letting the bike set this long, and that at this point, the carbs and fuel system WILL need to be cleaned/rebuilt. I'm just curious about a correct answer to file away for future reference.
Thanks!
