Weird experience - bike behaves very differently on certain tracks.

oh, almost forgot - i took the Aprilia 250 out for a spin on Sachsenring circuit with the wheelie and traction settings off, (no engine braking setting available) and now she is behaving as it should be - no more spluttering.
thanks for the assist, one and all! 

Good to hear you've got it sorted..... I seem to remember PeterV had exactly the same issue, nearly two years ago I think it was now, TC and anti-wheelie settings was the problem.
I think the TC and anti wheelie cutting in are exaggerated at Sachenring because the front and rear ends tend to get light over those rises and dips more often than most tracks we have?

Anyway... good to hear your sorted mate.
