Question Intake fart?

Here's a [hopefully] quick question for the collected wisdom that is this thread...

My FE570 has been running a little odd lately. Starts fine (rarely, if ever, needs the choke - even on colder mornings), but then it'll idle for a bit, and I'll get a loud fart into the intake (with a nice puff too, when the seat's off) and it'll cut-out. It'll do this several times until it's really heated up. Sometimes subsequent starts take a few seconds on the magic button.

Other than that, everything runs fine.

I suspect it's time for a valve check/adjust... but don't know what slightly out-of-spec valves might cause this behavior (and I really don't know if they are out of spec, as I haven't checked yet).

Any other suggestions?
