I get the occasional popping from the exhaust when off the throttle.

Does this mean I'm running a bit rich and is it anything to worry about ????

AFAIK popping could as easily be a sign of leaness rather than richness.

Is yours already derectricted ?

Manu, yes. It's had the air fliter, chip wire cut and baffel bit removed.

Think I'll pop the plugs out this weekend and have a nose.

Harry - get a descent slipon?

Mine popped on decel with just airbox mod and its gone away totally now with my Blueflame carbon job.

I belive the 2nd map u activated expects a race or straight through exhaust - I read somewhere else on here the standard can with baffles removed doesn't finish the job...

I may be wrong...all I know is mine has definitely stopped doing it.

I've ridden my Tuono in those 3 configs:

1. Derestricted airbox, wire cut, stock exhaust.
2. Derestricted airbox, wire cut, debaffled exhaust.
3. Derestricted airbox, wire cut, Akrapovic slip-on.

With config. 2 I don't really get popping but I sometimes notice a tone change in the exhaust note on decelleration at low revs: a deeper rumbling note. This appeared after the exhaust got debaffled. Maybe something to do with the cat ...?
Never had popping with config 1 or 3.

Popping = Lean. Probably no big thing, but i agree with Darski, get a new slip on (I picked the TI Aprilia one) that has a chip.

I had popping when I had a derestricted stock exhaust and airbox, but the stock chip. Went away with TI and new chip.

Also, I thought the new Aprilia's did not have wires to cut?

Euro models have the chip with 2 maps.. so wire can be cut.
