Hi I am experiencing similar issues. However, I changed the fuel filter. It seems to have gotten better, but have not ridden enough to properly assess the problem since I replaced the filter. See the thread

I thought my MV sounded strange with all the rattling noises, by hearing yours I see they are no different. Sometimes I think something is wrong with my motor. I check the oil before every ride and it is nice and clear. There are no MV's here to compare. Thanks for the vids. Where are you by the way. Add your bike to the registry!

theknurl,

it could be. i just don't get why the tech told me computer is not responding. he said in the invoice could be coil or injector. i ohmed the injectors, they are at 12 to 12.1 and coils are all at 9 ohms. i also took the throttle body and cleaned notice cylinder one lean compared to all 3

do you have one i can borrow?

i actually think i still have a plx m300(sold). ill check if i have will put it on a video
