Excellent video Robot, many thanks for the time and effort you put into this one. I’m sure that many of us will benefit from at least some of the countless tips and instructions you’ve included here. I’ll feel more confident working on my 2008 PX200 now !

Robot! You're the bomb. Thank you for posting this. I purchased TC's red 2005 PX 150 back in 2014. I live in Hawaii up on the North Shore. I'm not a super mechanically inclined person so this is a money video. Anyway, I've been looking for some help on how to maintain and repair the bike so this is super helpful! Glad to know too that I can send parts of the scooter to you guys to repair as well. Thanks again!

[@jeffcarroll6959]

Excellent video. My PX fuel line cracked and could have done with watching this first. Especially when local 'dealer' sold me one three inches to short and spent two hours trying to fit and then measured the old one and realised the 'dealers' mistake. Don't go there anymore. Stick to Daley's in Barnsley.

BEST SCOOTER CHANEL AT ALL: NO DOUBT!

[@alexandermangani3346]

Great video!! I have a restored Vespa 150 Super (VBC) with a non oil-injected LML (Stella) engine. Fifteen years ago I removed the carburetor and airbox but replaced the two paper gaskets with Hylomar RTV silicone sealant when reassembling the airbox and carb on the engine. That was 15 years ago. I haven’t touched the carburetor since. Also, I completely removed the clip on the cylinder head air shroud that keeps the fuel line from rubbing against the frame. That clip is a real nuisance.

[@Heather_D]

This is so incredibly helpful and well-done thank you so much!

[@VespaMotorsport]

Glad it was helpful!

[@Skavillekrew1966]

Many Thanks for the video, as a newbie Vespa PX125 owner and to Scooters as a whole this is perfect for us beginners, your Carb rebuild is one of the best on KZbin you've made it an easy to follow rebuild so now no longer scared to have a go. As you can appreciate most Vespa & Lambretta owners will be outside the US and purchasing wouldn't be possible, bit hopefully you can get to the point of making money through your video guides Or Dealership Sponsors and create more videos that are easy and simple for us Newbies. Big Thumbs Up from me.

[@royferguson3909]

newby or old - school, they are the best

[@maskedavenger2578]

Scooters like this were imported into Britain from India called LML Stella 125 cc 2 stroke engine .Later they were fitted with 125 Or 200cc auto engines but had some issues .I believe the company stopped building them & is now building motorcycles .I believe the owners of the 2stroke models keep them running with Vespa genuine & aftermarket parts .The engines were built with smaller carburettors because fuel economy is more important than top speed in Countries like India. .My brother still owns one a 125 stroker in Blue with a tan coloured seat ,his is very reliable & runs sweet & likes cruising around 50 mph .

[@RPWaggel]

Really good video. Because there are a lot of Vespas in the garage and want to go out. And the carburator thing is the biggest "problem" when the vespa was standing there for over 10 years.

Owned Indian LML NV Vespa for few years back in the early 90es. While it looked like a Vespa from a distance it never really felt like a real thing. Sold it and moved to a Piaggio PX. These days I ride a GTS. I do muss my 2 stroke PX 'devil', though.

[@MrTwamtwam]

ROBOT YOU ARE THE SHIT!! I love your videos!!!

[@Skavillekrew1966]

I've got a 1983 Vespa PX125 when I bought it, it had a DDR177 Kit. The issue I had was on long rides 50 miles at 50/55mph it would cut out randomly I'd quickly pull the clutch in and use the ignition button and restart and all would be well at 50mph. I wanted that extra speed as I also like to Peacock basically have loads of lights mirrors and chrome lol, hard to do when your Scooter cuts out. Last year I had a Malossi 180cc Kit fitted also a 28mil Malossi Carp I'd already had a Malossi Sports exhaust. Sadly on my way to Brighton the once, Mod Mecca about 30 miles in at 55 she cut off clutch in ignition restart whilst coasting and all okay at 50mph. Now I know its not soft seizing as I've recently had this Dyno tested and the fella said he'd got an extra 3 horse power from 11 to 14, and it would cruise at 60mph easy. Sadly this isn't the case I'm heavily invested financially and all I want to do is ride without these hassles, so would you or anyone know what could be the cause? It has been mentioned that the electrics are overheating and that a better Stator plate would be better and a better wiring loom again more money that I don't have. So before I get myself into trouble by taking a loan has anyone any ideas. Best Wishes Alan.

[@chaznasty814]

I have the same question. I got a 177 malossi put on. The shop said to add 2 stroke oil into the gas tank. I wonder if that’s why they told me to do that because of the oil line problem

Am interested to know how much they said to add?

Hi I have a 2007 px125 im restoring for myself. I cleaned my carburettor and before the clean it ran smooth with no smoke, after cleaning it is smoking I'm a bit baffled aswell regarding the mixture screw and the idle screw as my grandson turned the idle screw. It starts fine and ticks over but smokes. Do you have the amount of turns both the idle and the mixture screw should be turned out from fully in. Ps love your kids Thankyou

Hi guys. In the UK where i live these bikes are marketed as LML Starlite. You can pick these up much much cheaper than the equivelant Vespa ie the PX but how do they compare in build quality and reliability? Any advice / comments will be appreciated. Thanks

[@Skavillekrew1966]

LML Frames are not 100% exactly the same there may be other differences as well, you may get away with it with a 2t LML frame. The LML engine is bigger so you've a problem right off the bat, seems like a lot off work and effort for no real reward as it won't make it a Vespa sadly.

Hello, I have a 2016 Vespa primavera piaggio. It was sitting in a garage for 2 years and I doesn't start . I just got a new same carburator part number is cm158004 .

I took it out 4 months again and I might rmixed up the hoses. I can't for find connecting diagram. Maybe you can help me. I will pay you for help. Summer is gone and I lost all summer fun.

Yeah, gas in the gear oil is not good. Need to split the cases and replace the gasket and/or seals. Oil doesn’t evaporate so the gear oil probably got burned up when it passed through into the crank. Definitely going to be a huge bummer to whoever ends up buying this and the engine seizes.
