Vespa & Lambretta Ignition Fault Diagnosis vs Jetting Issues - Scooter Tech Tutorial 

Recently built a lambretta motor with a brand new 90 quid BGM stator, after 100 miles of running in I hit a hard pothole with the back wheel and started getting the not revving out half hiccup. Pulled the stator out and put in a really old Indian 12v one with a matched flywheel that I had lying around and all good. Only problem now is I don't remember where I got the BGM one from so can't send it back...good lesson there to keep all your bleedin paperwork

Now off into the garage to check mine. 😃. I know it’s working ok but no harm in double checking. Another great video. Thank you. 👍🏻

Definitely a must to look into! As my TV seems to be having the same issue at rev out, truly a good start in the problem solving quest!

Learnt something today...thank you very much!

Excellent videos, hope you are well, long time no see, looking forward to the next

That Vespa just sounded like my neighbours flymo 🤣 keep up the good work DM

Brilliant advice 👍

Have ya a video on the points system with the same things happen dan .cheers

I've had problems with people's scooters black box pick up holding back and not reving out

Dan, thanks for this very good. Riding my TS-1 the other day it started not pulling properly above 5K, was stuttering. I pulled over to side of road, i have fitted one of the external pick-ups sold by Scootronics, both pick-ups are wired through a switch so its an easy switch over between the two. Made a great difference, totally back to normal. When i got home i tried this test of yours on both pick-ups, and both revved quite happily up to 8-9K. So can the internal pick-up on the stator be breaking down because when riding its under much higher loads?

I have serious issue with my idle screw that doesnot decreses the rpm. I tried fixed throu mixture but no luck its being 1 month now. I have vespa super 150.. 1975

Thanks for the video. What’s the best way to measure the pickup height please?

Excellent video 👍

My px has had a new CDI and stator, did the timing using a buzz wangle and strobe, it will idle but won’t rev. I swapped out the carbys and I had power, coming home today, it died coming down a hill. Started straight away but wouldn’t rev, what should I be looking for?

I hope thats all is wrong with mine Dan (great video by the way )

Nice sound

Hi i got a vespa with a polini 177 bolted on with a revolver exhaust and a 24m carb but was wondering on what is the best sprocket to use cheers

We all hate Lambrettas 😂
