Hi all.
Just back from a 3 day ride through the mountains on my '14 Griso. The bike has a Termi pipe which I had fitted with the 1st service. It has the baffle left in, given I had read plenty of stories about how important it is to have the correct resistance in the pipes for the 4 v engine.
Now, I have a dilemma. The pipe sounds awesome under power and when cruising, but under a trailing throttle, it sounds like a WW2 Spitfire fighter. It pops crackles and basically makes quite a racket. It's particularly noticeable when engine braking on a downhill run into a corner. The bike has zero mods. Factory map. Valves were adjusted on 1st service. A bit of surging evident at around 3,500rpm. I use 98 octane fuel.
So, is the pop and crackle normal with a Termi, or is my bike poorly tuned? Is the factory map able to accommodate? Any help greatly appreciated.
Brent.
