Bike cuts out on idle, sometimes

[wato39]

When i first start my bike (748R) up it idles perfect maybe a touch slow , after riding the the idle seems to drop a bit more and the engine will spit back up the intakes and cut out ,any ideas ?

Mine used to do something very similar......as well as popping on the over-run.....used to cut out when I gave it a big mittfull of gas at low revs too.

Took it up to MD Racing in Ewell for an annual overhaul and Mike completely re-mapped the chip.

It's been utterly perfect ever since.
