Ladies and gents,
My LX150 with c. 6K miles and no history of problems Quit while running at around 40 MPH on a steady throttle, just a couple of miles into my commute. It would turn over, but no hint of firing up. Battery was strong. I ended up trailering it home.
It's carbureted, and bog stock.
Went to investigate the following evening. Took a suggestion from this forum and tried the brown key; fired right up. Thought I had it sussed, swapped back to the blue key; fired right up.
Tried several times over the next few days; fired right up every time.
My granddaughter uses the Vespa a lot to save patrol money and now I won't trust it.
I had to leave on a trip so haven't had time to investigate any further.
Strangely, my other Italian beauty, a Ducati 1098, did exactly the same thing a couple of months back. I put a MOSFET Rectifier in that and it seems to have stabilized.
Are there any common causes of such behaviour in a Vespa that I haven't discovered yet?
Any advice is greatly appreciated.
Jim M.
