Thank you so much for this video , my neighbour asked me to rebuild his 250 , never pulled a bike engine apart before, im a car mechanic and only ever worked on cars , this video is very detailed and made me super confident in pulling it apart ! I made my own puller for that huge crank seal but bought the tool for pulling the flywheel off an online shop …… its all stripped down so i’ll start the clean up of all the parts soon then i will be following part 2 for the rebuild ! Again THANK YOU from me in the UK 🇬🇧
I just want to say that the Vespa in this video is my vespa (I had no idea they made a video of my rebuild) and these guys did a tremendous job for me. I could not recommend them more.
@@dtiydr What kind of oil consumption were you having that it would run dry?? I had an X9, it used very little oil from one service interval to the next. Similar engines, they really shouldn't need oil between services. Sounds more like something went wrong. Oil pump, perhaps, as you said.
Just finished the disassembly of a 2017 GTS 300 engine that had been oil starved... crank is frozen but everything else looks great. Thank you so much, following along step by step, really raised my confidence that I could do this job!
Excellent video. It is always a pleasure to watch a properly experienced craftsman at work. You tube, is sadly, often full of "Inexperienced" people doing "How to videos" but this is on a whole different level. Thanks for posting this video up!
Thank you so very much for the video, the penchance for detail is exceptional, looking forward to the other parts. As an owner of a newly rebuilt P200E Vespa, I cannot overstate how much simpler the 2 stroke motor is. I don't think a layman should attempt his luck with the modern Vespa motors.
Wow i actually watched thru this all. And im highly likely not going to take apart my primavera myself and hopefully not any mechanic in the near foreseeable future. But i am sure as hell not going to miss out on the oil changes! Nice vid btw!
I want to put my Aprilia sr max 300 into a container and ship it to USA in order to have service from mr Robot' s hands! I don' t know if the vast majority of American people are so professionals, but the guys in this garage are simply awesome!
very cool the thing about buying a vespa for me is that like my grandpa's yamaha I can keep it and fix it for decades to come unlike the chinese scooters
hi Robot...i need to change the head gaskets in my Gilera st125 which has the same engine as the one you have here ..do i need to take the engine out to do it as ill never be able to remember how to put it back lol
I wish you guys would do a tear down and rebuild on a Piaggio 50cc 4t-4v! I have a 2014 Aprilia motard, I have been trying to rebuild fo months. Its hard to find any info on this engine. The only info I have been able to find is the 2 valve or 2 stroke, nothing on the 4 valve engine
Hi Robot! I love your videos, very detailed and have learned a lot by watching them. When you started up the blue vespa, you said "there's a distinct metallic wrapping noise, and that's from the main bearing that's falling apart and damaged from lack of lubrication." Later, when you removed the piston, you showed how the crankcase had some play and was due to the connecting rod big-end bearing, not the main bearings, right? So even though the main bearings had some galling, it was due to the big-end bearing's vibration, but not enough to warrant replacement, right? I have a BV200-like scooter (it's really an Aprilia Sportcity 200 sold in Latin America, but mention the BV200 instead because that's a better reference and I've installed a bunch of Piaggio Beverly engine parts already that are identical) that has a similar wrapping noise, but not as loud (perhaps because of a smaller engine?). My question is whether you know if the main bearings can be replaced on the crankcase in case it comes down to that. Buying the crankcase is out of the question (aprilia lists it for $900), so I'm hoping that it's just the crankcase that's damaged, not the bearings as well. Someone mention that some crankcases require heating in an oven in order to remove/install the bearings. Do you know if this is necessary in case it came down to having to replace the main bearings? Thanks for the great videos and I hope you have a chance to seem my question...
I'm assuming you meant "crankshaft" instead of "crankcase?" I guess the ability to disassemble and repair crankshafts is a function of their design. It would be interesting to see someone try it.
I don't even have a vespa or even a scooter and I couldn't stop watching how do you know all that, and how much does a job like this cost? How long does this take to get your scooter back?
I got a 2019 Gts 300 HPE that got a new crankshaft with 3k miles under warranty. Now with 16k miles again needs a new crankshaft. In this repair the dealer changed also both chains (oil and timing), piston rings. The bearings and oil pump were not changed. What could cause a second crankshaft to go bad in such a short period??
Im.an Auto mechanic by trade I just bought a no start 2001 Vespa 49 cc it some how has a cracked case on the top of the mount to the body. Is it possible that back pressure or compression is being lost propagating the no start? I've yet to get on it since the rain we've been having in Georgia. I Believe it may be a fuel issue I hope, gas tap w vaccuum diaphragm stemming from the gas tank. I'll try a gas IV bag. Any suggestions before I get on it? Indeed the crack in case needs to be welded only 3000 miles on it. Perhaps valve's. We'll see
How did you was the engine? Is there everything water proof insight? Great videos you are producing, love watching them! Greetings from europe/austria!
hello from Portugal. i have a piaggio fly 125 ei, 3v. and that was stopped for a few months in the open, cleaned the air filter and saw that there was water in the filter box, changed the oil 1.2 liters, cleaned the small strainer and put a new filter. I start the engine and the oil light does not go out. I stopped the engine after 20 seconds. I checked the oil level and it was low. I put another 100ml of oil and start the engine and the light is still on, I accelerated a little and the light went out but when I go back to idle the light turns on. I removed all the oil, checked the strainer (it was clean), I put the oil that was only 1.2 liters (the 100ml were inside) I start the engine and the light is on. I check the oil sensor plug and tested the connection and everything is ok. remove the sensor and start the engine and no oil comes out. Is there anything else to check or do I have to remove the oil pump to find the fault?
In this time 1:03:56 i can see the top ring is flat part face down, correct?. I think in an other Video you said the top ring it was flat part face up.
Hey my friend! I would like to know the dimension of the "O" ring what you show at 1:14:51. I would like to replace it, but can't find anywhere. Thanks for your kindly help!
Nice vedeo i have a problem with mi vespa i Turn the Key to lock position and press the unlock button and the SEAT is open...du you know what the problem is.. please
he says there's a way of finding out the clearance's of the crank cases so you can differ from fc1 to fc2 but gave no information on how to find this out I'm doing a rebuild but had to order a second hand right casing but have no idea weather its a fc1 or fc2 as there's no way of finding out robot said there is but gave no information this kind of fills like areal life Easter egg if any one knows how to gain this info except for the obvious numbers on crank as cranks buggered so need a new one so the crank number don't matter i need to find out weather the right crank casing (small one) is fc1 or fc2 please let me know

Instead of watching this long video to find out. What happened to your motor? @ mileage?
You were indeed fortunate Sir.
@@dionmoore879 Forgot to top up the oil or something wrong with the oil pump.

You appear to be very professional!
You definitely know what you’re doing. Enjoyed watching very much.
Thanks for taking us under the hood as it were. Interesting stuff.
this is amazing. There is no words to describe this. master class.
Thanks robot and vespa motorsport.

Yes the old Vespa are more home mechanic friendly then the new ones when it comes to major service!
Awesome upload, going straight to my faves as I have the exact same model :)
Awesome Video! Super detailled and excellent explanations of every step and eventual pitfalls. Thank you so much!
Thank you. I’m taking apart now and ordered parts.
Robot, you are a badass. I think you could rebuild a Vespa with a blindfold on. Great instructional video-thanks so much!
Wow i actually watched thru this all. And im highly likely not going to take apart my primavera myself and hopefully not any mechanic in the near foreseeable future.
But i am sure as hell not going to miss out on the oil changes! Nice vid btw!
Spettacolo, bravissimo
AWESOME!
LEGEND!
The man, Robot.
Robot for President!
Excellent Robot. Thank you.
Best channel ever 👍👍👍
Thanks so much for this video
I want to put my Aprilia sr max 300 into a container and ship it to USA in order to have service from mr Robot' s hands! I don' t know if the vast majority of American people are so professionals, but the guys in this garage are simply awesome!
I want a Vespa Motorsport t-shirt with a picture of robot that says "No big deal." Yeah.. this is a big deal Robot! :) Nice work.
Mechanics certainly do earn their pay!
Awesome stuff!!! Ty
This is like watching a brain surgeon: it also inspires confidence.
Interesting, it is hard to remember where goes what when reassemble. Great job Robot! I would surely have some spare parts at the end.
Well done boy
Great shirt, Robot!
What a pro!
very cool the thing about buying a vespa for me is that like my grandpa's yamaha I can keep it and fix it for decades to come unlike the chinese scooters
Bravissimo
Veramente bravi
Awesome! I need a Robot here in Costa Rica! Maybe the real Robot want to visit my country!
Come on man, come to see my LX150 in CR! Pura vida!
Robot's the man!
I have a liberty 125 it has a leader ac engine do you have any kits for them
Yes, the 187 Malossi kit fits.
Thanks for the compliment....I only wish I could be a full time UA-cam star! Robot.
Vespa Motorsport Faker
Robot- American Hero.
hi Robot...i need to change the head gaskets in my Gilera st125 which has the same engine as the one you have here ..do i need to take the engine out to do it as ill never be able to remember how to put it back lol
Damn I've been having a lotta problems with my GT 125.
This is probably the reason, I've had a breakdown due to temperature before, too.
Yeah bud the heads warp big time. Good luck bro...
What would be the cause for a crankshaft need to be replaced, high revs, dirty oil . Thinking of taking on a project vespa .

How did you was the engine? Is there everything water proof insight? Great videos you are producing, love watching them! Greetings from europe/austria!
The engine can be safely washed with water, it's well sealed.
Is this repair being done under warranty? Or has the warranty expired.?
Love your detailed videos and your subject knowledge.
Warranty expired on the 2015 scooter we serviced the engine on, plus running your scooter out of oil is not covered under the limited warranty.
Hi could tell me how reset the engine management light on my kymco400i thanks

Is piaggio’s 500cc engine mostly the same as this engine?
Is there a way to pull the flywheel without that special tool?
Hi Robot, could you please make a video on how to change a malossi airfilter on a Primavera i-get?
Peer S. Hansen just take off the sideskirt, open the airbox, get the stock one out, oil the new malossi airfilter, and close up the patient!:) voila!
👍👍👍😀
Part 2 video rear box ??
Your videos are great...but can you PLEASE sort out that constant ringing sound.
I recommend obtaining a workshop service manual. Read through it a few times.

Good morning, could you indicate how to phase the GTS 300 engine, thank you, regards.
Leader engine or Quassar? your choice?
In this time 1:03:56 i can see the top ring is flat part face down, correct?. I think in an other Video you said the top ring it was flat part face up.
Hey my friend!
I would like to know the dimension of the "O" ring what you show at 1:14:51. I would like to replace it, but can't find anywhere.
Thanks for your kindly help!
Sorry Robot but they're Torx not Torax screws, and the hollow ones are Tamper proof Torx.
Nice vedeo i have a problem with mi vespa i Turn the Key to lock position and press the unlock button and the SEAT is open...du you know what the problem is.. please
How many miles do those machines have on them, mon amour?
Great video robot ...
I have a vespa gt 200 2006, but the problem is that the coolant mixes with the engine oil.
What do you think the problem is?
leaking gasket
head gasket is blown or bad,... orsomehow mis-routing the coolant hose to the intake manifold instead of the carb heater
Looks expensive :-o
Hey Robot, How long would this tear down take you without the cameras?
When it comes to repairs I do routine, I can get them done fast. It's a fine balance between being quick and detail oriented.
How much did that job cost? thanks
Hi there
Where can I buy a tool called 147209 on the video at 1hour 11 mins? Thank you so much.
8140729. Give us a call and we may be able to special order it for you. 619-280-1718
Sir Vespa engine khatar khatar sound problem he please solution
he says there's a way of finding out the clearance's of the crank cases so you can differ from fc1 to fc2 but gave no information on how to find this out I'm doing a rebuild but had to order a second hand right casing but have no idea weather its a fc1 or fc2 as there's no way of finding out robot said there is but gave no information this kind of fills like areal life Easter egg if any one knows how to gain this info except for the obvious numbers on crank as cranks buggered so need a new one so the crank number don't matter i need to find out weather the right crank casing (small one) is fc1 or fc2 please let me know
From France - Thank You very much, could you make it in French. Just kidding. Merci
My God ,the motor is new!Why disassembly i don't understant.
crankshaft failure of the big end
Don't run your scooter out of oil or coolant! The new Vespa motors are very good as long as they are maintained!
Looking
Bs 6
Hi robot tbe pats no 8140729 can we buy it???
