Thanks for the tips. Last Guzzi I had, a Mille GT, made some incredible changes by adding pipes, carbs, larger valves, coils but the biggest gain was from lightening the flywheel. This single change was just day and night. There was 4.5kg taken off and it felt incredibly better in suspension, revs, engine braking.
I also recently built my ducati Cafe Racer and reduced the flywheel to 300grams, high compression pistons, remapped ECU with PC5. It feels unreal to ride, lightning throttle and wheelies.
So this is why I am asking, what mods are the best, Hi compression pistons, lightening the flywheel, ECU, i think it has pipes already (i havent seen the bike yet, its on the way, was a friends bike). Also he has pressurised his air box with some pipes from the front to the airbox on his Coppa Italia and previously on this bike and reckons theres improvement with the colder air.(anyone else done this ?)_. .. I just want to try and get it right first time around.
