    Hi all,

    I have a 2009 Fatbob that has about 5000ks on it. up until now it has all been smooth sailing. however, on the wau back from the snowy ride, the bike started to run very rough, with uneven power delivery and down low would back fire and spit and burbble. Even when revving in with the clutch in  it sounded like a gemini with a 3" exhaust. The problem cleared up for about 30ks and the came back again. I have a heavy breather, V&H Big Shots and a Big Joes Fuel shot. I cant say for sure (if it's the cause) but i did start to nitice the issue after my last fuel stop on the way home, I'm hoping that it is just bad fuel. Has any one got any ideas or had the same problem and knows the fix.

    Cheers
