Today i have nothing to do, so i open the motor of my Piaggio Fly to see what happen 3 weeks ago when he overheat...

Here what i see!!




Inside the cylinder everything look good!


At the dealer, a mechanic said to me the piston was finish, before i open the motor it works well and always hit 45~50 mph!?
I clean the piston and all the black is gone now!

Do you think i can use again this motor, only 800km...? :-?

Today i order a jet #92 for my 20mm carb.

I think you can as long as the rings are good, it got a little hot on you, so be careful and do not run it lean.

No no and no, your cylinders glazed to shit, scotch brite pads, marvel oil, the piston had a bit of a hang up seizure + blow by the rings. No scuffs = reuse but the piston looks like pure garbage unless you got all day to slap that hoe with some sand paper on the burnt side. I am a 2 t guy with auto excellence skills. Be better ofd ordering a new top end then to piss off the motor as the circlips still need to be replaced as well for rings. Last thing you want is to throw a rod from metal to metal hang up.
