Modern Vespa

Yes luckily I can return the engine, just need to pay the transport costs

Leave this answer with me while I ask someone who is more skilled at diagnostic sounds and symptom's but it may take a couple of days.

I just typed in vespa and it came up within my area..glad at least you can return it..

I'm going mad..the engine is advertised on shpock as a 2017 125cc gts..in London
Sorry for confusion

This is the advert..

Thanks for that, I'll send them a message for more details. But I think because its a 2017 engine it won't be suitable

So it seems piaggio made 2 engines for the same model in 2012 then..did they carry on with this on other years..
Is there something special with the original engine like more power or is it just emissions..
The prices seem to be higher for the original engine

Found this on eBay for £400

Says 2016 super ie 125

I spoke to an ex Vespa mechanic this afternoon, he states I have the engine that replaced the Leader and he believes it was Chinese.

I have found stamped on the engine MC 01 IS.

He seems to think I need the exact same engine, as the water pump set up is different.

I just checked on sip and it appears that you have a 3 valve head..this engine is also fitted to the primevera model which is available in 125cc or 150cc..

Engine prefix M455M is a UK market 125 4T ie engine

I found this quote from a post on here in December 2012, this is the engine I had in the bike as the engine number starts with M455M. Slowly getting there!

The plot thickens!

Done some more research and it appears the engine I am after was also fitted to the Piaggio Beverley. This appears to be the same engine apart from the swingarm.

sorry with all the posts tonight, last one I promise.
So I discover my engine is a M455M, put that in to Google and this appears advertised as a M455M engine, however the right hand side is different , doesn't have the ECS letters stamped on it and cooling pipes completely different. Totally confused again

Look for primervera engines..same engine

Both of those are different to what you have..

Quick update, finally found the correct engine from a stolen recovered bike, which had 15000 miles on it (Mine had 10000). After a few false starts; one being a broken exhaust manifold stud, the engine was finally fitted into the bike today fired up first time and runs great.

Thank you all for your advice.

If anyone in the UK wants a GTS 125cc engine with the big end gone on it as a project or for spares let me know, just ask you donate a small sum to a charity.

Thanks for adding that - it's always good to know when problems have been sorted.
