***update***

so had a new fuel injector and belt fitted 6 weeks ago (was going to Kelso scooter rally from hull) seem ok going 70/75 all the way.

on the way home had a few problems with the same again.

know its back to how it was before.......

its when it gets warmed up....65/70 really bad jerking like as posted flicking of a clutch.

you can rev through it but when you slow down it is REALLY bad.....shit

I’ve also got this problem. Like someone is pulling me back or the belt is slipping or fuels starvation. But only at about 60-70 after 70 it goes away and it goes fine all the way in to the 70s.
I don’t see how the belt would only slip between 60-70. Not sure how the Rev limiter works but would that also happen between 60-70? I heard it might be the fuel pump so I’ve put a new one on.
Is this something to do with the ECU?

Fran - If you have a MIU G3 ECU - Check so you have the latest MAP (Ending **BN15) There was a Bulletin about this in late 2013 and the new map was released for exact same problem as you mention.


Mine is a 2012. How do I find out if I have MIU G3 ECU and check the mapping?

I’d imagine you’d have to visit your local Piaggio dealer.

Hi,
Just a thought, if you have the piaggio multimedia platform app, it should tell you how high your engine is revving at selected speeds. Also, I had a problem in the past, where the HT coil would mis-fire when hot or on a long run...
