Hard Starting Including Backfiring (Loud Blasts!), But Seems Fine After Starting
When trying to start ours (a 1990) when cold or even when warm and having sat for 20 minutes, it takes a massive amount of cranking to finally get started. Once it starts, it runs good, idles smoothly and has lots of normal power.
Note: Since we are in FL, the bike never sits, and is used very regularly.
Also noticed, was that is seems like the gas tank pressurizes while cranking to try to start. We heard a hissing sound after unsuccessfully trying to start, and found it came from the gas tank fill cap.
Any ideas? Thanks!
