Thank you so much Robot and Scott for your detailed guidance! My vespa was leaking oil and I decided to replace all the top end gaskets, and I was overjoyed when I cranked the engine today and it started like nothing. I watched all three of these videos and followed them like a bible. I never would have had the confidence or knowledge to attempt this without the detail of these videos. But it was an awesome experience to be able to take apart and work on complicated machinery.
Very well done, Robot. I watched all three videos. Not because I believe I will ever try such a project, but because I like to have at least a working knowledge of the workings of the engine. I have an eight year old GTV300 that is still going strong. Your videos have helped me maintain my scooter and I can't say enough about how much you have helped me. I only wish we had someone of your expertise here in SE US just in case the need should arise. Again, thanks to you and ScooterWest.
I don't even have a scooter,but really enjoy watching your videos,you certainly have an eye for detail,and high standards,Vespa owners in your area are certainly lucky to have your services.
its wonderful to watch a true master of his trade at work. The technics, depth of knowledge and honest opinions shared in an informative and entertaining way makes this compulsive viewing
Thank You for this one and only full diassambly-reassambly video. You are realy a profi mechanic. Many thanks also for your photographer. Greetings from Budapest/Hungary
Your expert mechanic work has given me the confidence to do my own work I have always worked on car engines but never Small Engines thank you you're a very good teacher
Thanks Robot and all at vespa motorsports i recently replaced an HT Lead to the coil on my 300gts it involved a lot of swearing and one heck of an electric shock!! I just sat through all 3 videos and am amazed at just whats inside one of those things ...A great and very professional job
You have done a great job. Very very interessting and I learned a lot. I thank you and I wish you all the best. I drive a Piaggio X9 125. Best greetings from Klaus from Hockenheim GERMANY
Hello from Scotland what can I say the mans a professional genius really enjoyed this video I don’t own a Vespa but thinking about getting one ,I own the cheap copy a Chinese lexmoto milano it’s been a good little scooter to be fair.
awesome! im from Singapore and its hard to find a reliable workshop here for vespas.. atleast now i have an idea of what to look out for when they work on a vespa
Just Awesome !! Robot... Thank you very much. Now those factory tools, have to make generic ones so we could undertake something like this. I'd like to know what torque wrench you use and why you prefer it? Also when you get a chance maybe you can do a video on a basic socket/tool set every Vespa rider should carry to tackle things like belt/roller replacement etc. I have enjoyed all the videos you and Vespa Motorsports has shared and have benefitted from the parts that i have had shipped to me. Thanks for sharing and maybe others will be inspired to share like you...
Questo video ha un pregio enorme,mostrare quanto tempo e precisione richiede un lavoro simile,giustificando quindi il costo della manod'opera che spesso viene definito(dagli incompetenti) esorbitante...
Hi Robot, thank you for your learning, really appreciate it. I'm doing all my DIY work on my 300 GTS thanks to your videos. Just 1 question : i've changed the cylinder, piston and cylinder head of my 300 GTS 2010. The cylinder and piston are brand new. I'm not sure of the position of the piston rings. I have the Haynes manual, and they to not advocate the same position for the piston rings as you do on your video. I've been mounting 2 times the piston/cylinder with 2 different position for the rings. Everything is torqued with a torque wrench. (follow the Haynes sequence, 7nm, 10nm, 270 in cross for the Cylinder head bolts. Valve adjustment OK (In: 0,10mm / Out 0,15mm), base gasket 0,4mm (the thinner). The spark plug is black but not oiled. I guess this is due to my injector, maybe too rich. Which is an old injector i just bought recently. 1st time i started the scooter i had no compression, engine was runing very low. 2nd time (now) i have more compression (100psi), the engine goes to 20km/h max. Put some oil inside the spark plug hole, testing with a compression meter and the compression came to 150psi. So there is a problem in my piston/cylinder. Which one ? Are my piston rings gap misplaced ? And, not sure to understand, but the oil scrapper ring gap should be at 12' oclock, the middle one at 4' oclock and the upper one at 8' oclock is that right ? Thanks for your help ! Thibaut
Great video. Thanks for the hints, tips and tricks. About the valve clearance. Do you know what it takes for a 125 gts ie? The manual says 0.02 - 0.05mm which is nothing, is this correct? Greetings from Austria! 🇦🇹
very good job mr robot. i love that vespa but they are realy expensive here in europe...the cheapest 1 cost 3.500 euro...lot of money..but soon i wil buy vespa...great work and very good technisan you are...
Thank you very much for sharing. I learned a lot from you. You are a great master. It would be a pleasure to work and learn from you. Greetings from Germany One question I still have. Have you a hole list what I need? A komplett list would be a pleasure.
I don't know anything about scooters that's crazy I that watched this whole 3part series, how often does this need to be done, and how much will it cost.
Hi, in my BV 250 I found that the 1st piston ring (the one with the L section) had the flat side toward the bottom. That seemed very weird to me. -BTW your videos are amazing, thanks
Greetings from Scotland. Robot, I have a hypothetical question for you, if a nut was to vibrate off the valve adjuster, where could it go or end up? Regards Frank
I work in a Vespa rental and this vídeos are gold to me. Having trouble with the 2015 50cc 4 stroke primaveras. They are difficult to start and keep staling until warmed up. Any suggestions? Valve adjustment perhaps? They are about 6000km/4000miles
Hi,I have a gilera runner 125 I’m thinking of putting a Vespa gts 300 engine in it are they all fuel injected and would u no what year of engine which is carburettor ran thanks.paul
Hi brand new engine can i but it for my beverly 250cc it makes a ting tingtingting noise constantly and also if i hit the trotthle i dont know how or wher it comes from ? Have you more information thanx.
Interesting for a seasonal machenic like me, learned a lot though I don't own Vespa but I have Honda cb it has an ohc engine the machanism is the same so this video help.
Hi Robert, i forgot the plastic Plug on 57:10 and started the Vespa. Air blows out of the opening. Is that normal? It sounds like the exhaust is leaking.
Jeff (and team at vespa motorsport), i have one question. I am in project of rebuilding piaggio beverly 200 (leader engine), i've skimmed about 0,10 mm off the cylinder head due to low spot near the one of the coolant passages and i am wondering which base gasket thickness to use, current gasket is 0,6 mm. Should i stay with 0,6 mm, or go higher and use 0,8 mm? Will the 0,2 mm. difference have big impact on compression ratio?
May I have accurate stud screw Newton meters value? As I tried to use your final 24 foot pound convert to Nm which means 32 Nm (Using google to transfer it gave me 32 Nm), and I got broken stud screw as result :( Looks like I used wrong unit to convert to Nm? 24 foot pound stands for 24 ft-lbs, correct?

Thank you Robot.
I like the design of the water pump impeller, that is much better than the rubber flapper design.

Thanks for sharing!
Great tutorial! I've never done this myself but definitely got interested in doing this. Thanks a lot Mr. Robot and regards from Finland!
You are welcome, good luck!
This is like having a hand-built Vespa, like a Rolls Royce 🛵
very good tutorial thank you :))
Really hope the vespa technicians in the uk🇬🇧 are up to your standard.
I'm thinking of leaving motorbikes and buying a 2023 vespa 300 😊
Thannk you very much!
Really clear description!
Glad it was helpful!
Abbastanza complicato neee e comunque molto bravo e scrupoloso... grazie
100% hand service, super...
Thank you very much for sharing.
I learned a lot from you. You are a great master. It would be a pleasure to work and learn from you.
Greetings from Germany
One question I still have.
Have you a hole list what I need?
A komplett list would be a pleasure.
Good job robot.. Thanks
My pleasure!
Hey that's my Vespa!
I don't know anything about scooters that's crazy I that watched this whole 3part series, how often does this need to be done, and how much will it cost.
Hi, in my BV 250 I found that the 1st piston ring (the one with the L section) had the flat side toward the bottom. That seemed very weird to me. -BTW your videos are amazing, thanks
Hello. In this Video you said the compression ring flat part is face up, but in the first Video i think the flat part y face down. Yes?.
Greetings from Scotland. Robot, I have a hypothetical question for you, if a nut was to vibrate off the valve adjuster, where could it go or end up?
Regards Frank
What kind of paste is the blue one?. 59:05
I work in a Vespa rental and this vídeos are gold to me. Having trouble with the 2015 50cc 4 stroke primaveras. They are difficult to start and keep staling until warmed up. Any suggestions? Valve adjustment perhaps? They are about 6000km/4000miles
Try checking the valves and replace the spark plug first.
@Vespa Mitirsport where is the oil pressure sensor located please? Is it the connection on top of the head next to thermostat housing? Kind regards
Top Video

Hi,I have a gilera runner 125 I’m thinking of putting a Vespa gts 300 engine in it are they all fuel injected and would u no what year of engine which is carburettor ran thanks.paul
I like your watch. Automatic??
Robot = Legend
Hi brand new engine can i but it for my beverly 250cc it makes a ting tingtingting noise constantly and also if i hit the trotthle i dont know how or wher it comes from ? Have you more information thanx.
What would happen if I used a 300 headgasket on a 250?
squish clearance ?
That top ring L shaped sits the other way around dosent it surely because the ledge is the other way around
🤔Now are the high performance air filters good for your scooter? 🤔Or should you just leave it like it is?
Sir, make a video total overhoul engine sprint 3vie please
Interesting for a seasonal machenic like me, learned a lot though I don't own Vespa but I have Honda cb it has an ohc engine the machanism is the same so this video help.
Awesome, glad we could help!
Hi Robert, i forgot the plastic Plug on 57:10 and started the Vespa. Air blows out of the opening. Is that normal? It sounds like the exhaust is leaking.
شكرا
amazing job!! what brand is your torque wrench??
Thanks! I believe the one in this video is a Matco. Ecellent tools.
what did this overhaul cost ? time and money in total
What kind of watch is that
Jeff (and team at vespa motorsport), i have one question. I am in project of rebuilding piaggio beverly 200 (leader engine), i've skimmed about 0,10 mm off the cylinder head due to low spot near the one of the coolant passages and i am wondering which base gasket thickness to use, current gasket is 0,6 mm. Should i stay with 0,6 mm, or go higher and use 0,8 mm? Will the 0,2 mm. difference have big impact on compression ratio?
If you do not do the deck measurement, I would recommend the 0.8mm base gasket
how many km did this vespa have ? what was the main reason for this overhaul ?
Hello, I am a Vespa GTS 125ie player in Vietnam. I am thinking of upgrading to vespa gts quasar 300. Can you help me with more information.Tks
How reliable are these engines if
May I have accurate stud screw Newton meters value? As I tried to use your final 24 foot pound convert to Nm which means 32 Nm (Using google to transfer it gave me 32 Nm), and I got broken stud screw as result :( Looks like I used wrong unit to convert to Nm? 24 foot pound stands for 24 ft-lbs, correct?
👍👍👍
How long does this job take? It seems like you could do it in a day. Not me tho I could hardly change a tire lol
It's a 5 hour job for a full rebuild.
👍
i would use some mor oil in the process its basically dry everywhere!
