Ive only got 200 miles on the clock of my new V4 Tuono so bear with me.

I find the fuelling to be very lean. on small constant throttle openings , say doing 30 or 40 in 2nd or third the engine feels as though it is "hunting". Is this common and does it get better with age/miles or is that just the way it is?

Also, I am running in "T" mode at the moment and find the throttle response a little snatchy from a closed throttle. Again, is this normal or would the other maps be better? 

I know I could try the other maps and experiment a little but the weather is sh*te. Ive had the bike 2 weeks now and only just managed to put 200 miles on it.Cry

Your coming from a bike with almost no emission concessions to one with a shed load so it will run as lean as they think they can get away with at certain revs in stock form. Have you checked the free play in the throttle ?

Great, that Gabro fella knows his stuff. I have run one of his chips on my Mille for years.
