    Engine mapping is the programming in the bikes ECU memory that controls the ignition timing and the fuel mixture. I assume it comes ex factory. However I believe some models of the V7 have had updates and Mario should be able to programme these. A lot of V7s had starting probs, and updates sorted this. Has the bike always run rough or is it a recent thing? If recent, its probably not the mapping. Are you running aftermarket mufflers? Has the tune changed since?

    Google "Beetle Maps". Mark Bayley creates maps for Guzzis with various different muffler configurations. I wouldn't have a clue how to download them, mind. Someone here might chip in. Beetle gets much improved performance with his maps than factory spec.

    Otherwise running rough might just be crap fuel, plugs, etc.

    Is Thunderbikes servicing your bike? I'm sure Mario can sort it out.

    Factory maps have to reflect emission control standards, generally EU. Some factories have 'track' ecu's and or maps which are more performance oriented.

    I don't use aftermarket maps because I'm happy with what I've got.

    Being paranoid about lean states and burnt valves (1989) does factor into the equation.

    The paranoia may be misplaced but fuel/air mixtures are very easily changed . Without gas analysis you can only go by eye, experience and err instinct? that you are not running too lean.

    None of which I have. I run what Mario loads. For the Griso 8V now with roller rockers, the latest factory map is fine. The thing did 100hp on the dyno and I'm not hunting for a couple of extra horses.

    I had a few issues trying to start my V7 from new, it was the 2011 model (slightly different motor to the Stone me thinks!!) After kicking it in the guts many times and cursing italian profanity I kindly asked the doctor if he could help with the bike of course.
    Mario kindly twicked and waved his magic wond over da machine oh!! and replaced the plugs it never played up again. Many happy 1000s of ks riding.

    That's a joke, Joyce?

    Funnily enough the Griso 8V has a spare power with a green tom tom plug. I think stelvios do too.

    Can you imagine Google Engine Maps?

    The spark would get sent via the wrong or longest route most of the time.

    Or your google mapped bike will throw you into the side of a truck.
