I'm getting a bit of a flutter when i lift off, it used to sound more like a whip cracking when i lifted off the loud peddle.
Only thing i can think of at the moment could possibly be a sticky recirc valve (Forge 008 with the revised piston). going to pop the top off when i can get some high temp grease to re-grease the seals, I serviced it around 6 - 8 months ago.
Anyone else got any ideas? No EML light/codes etc
