Putting LML PX 150 into 1967 Sprint (VLB)
Hi, I’ve got a 1967 Vespa Sprint (VLB) with a worn out engine & 6v electrics. I’ve purchased a brand new LML 5 port 150cc engine. It’s got electronic stator & already has an HT coil fitted. The bike is the NON battery version. I think I need: - an LML CDI unit; there’s 2 on the Beedspeed website & I’m not sure which one I need. The stator has 5 wires coming out of it. - A regulator; will any universal one do, or is there an LML one ? - I guess I don’t need a rectifier ‘cos I don’t have a battery ? - Do I need the Rally conversion 12v light switch (again Beedspeed) ? - I fitted a new VLB loom,when I thought I'd be running with the 6v system; will I need a new one to handle the electronic ignition ? - the 12v conversion brake light switch (Beedspeed) - 12v light bulbs all round; brake light, rear light, headlight ? is that it? is halogen a good option ? - A Sprint bulb holder because I’ve lost mine. I went on the Beedspeed site & spotted what I thought was what I wanted, but 'cos I needed confirmation of some the parts decided to ring their order line. I rang from 13:30 to 17:30 & never got through - engaged all the time. I rang the postroon number & spoke to someone who told me they were very busy. Is there another source for what I want ? I don't feel like giving Beedspeed any of my hard earned cash now. Look forward to any replies Andy |

The Classic Scooter Shop via ebay. They have an ebay shop. It was their guy that made me aware of this forum. Regards Andy |

Well the good news is we got the engine in & it works, but it was much harder than anticipated. Having said that, most of the time was spent installing the new loom which was a complete b*stard to fit: - started about 09:00 Sunday morning - took seat off - petrol tank out - disconnected loom - disconnected cables - connected draw-wires to all bits of loom sticking out of the scooter & labelled them - pulled old loom out - connected relevant bits of new loom to draw-wires & started pull through process - 3 hours later finally got it done. - with old engine still in place, marked up the sites of the new CDI unit and regulator - removed old engine - drilled holes for CDI & reg & mounted them - installed new engine **TIP** watch out for cables coming out of central tunnel; fitted the engine & realised the cables had got routed over the crank case, so had to remove engine & do it again **TIP** fit petrol pipe to engine before installing engine as it's very fiddly to do with engine in place **TIP** check the width of the bottom mounting bracket of your rear shocker; we discovered that the mounting point on the engine was about 3-4mm wider than the bottom mounting bracket, so had to bend it open slightly; the bolt then is a few mm shorter, so I'll probablt try & replace it with a longer one. - filled with gearbox oil - fitted silencer - connected all electrics (I'd labelled all the various parts of the new loom before we started, using the handy wiring diagram which Beedsped sent with the loom). - the red, white & green connect from the stator connect to the CDI unit & the blue wire connects to the top of the coil. The white wire from the call needs connecting to earth. - the black & blue from stator go to the regulator (black is earth on this loom) & the grey connects the loom to the regulator giving it power. - turned petrol tap on & kicked it over - nothing - gave it plenty of kicks to get petrol through - nothing - rechecked all connections - nothing - it's about 18:00 now & the wives had cooked dinner, so we had a break for dinner & a Guinness or two. - I remembered I'd got a multimeter so after dinner we measured the output from the stator. Everything was fine to the loom; everything was fine going to the CDI. Nothing coming out of CDI to HT coil. Checked the connectors and realised this hadn't been connected properly. - kicked it over & it started first kick. Marvellous. Revved it a lot then tried to shut it off. It wouldn't. Ended up having to stall it before we all choked in the garage. - back to wiring diagram - it seems there should be a green wire connecting the CDI/HT to the loom; I couldn't find it anywhere, so we nicked a green wire from the old loom, connected it to the CDI & started the bike again. Started fine, so I touched the end of the green wire to earth & it stopped. - all I've got to do now is incorporate the green wire into the loom somehow & connect up the front/rear lighting & brake light switch & it's done. - 21:00 time for more Guinness & then bed. It took about twice as long as I expected, but the engine runs really sweetly straight out of the box & I'm really pleased with it.

Re: Putting LML PX 150 into 1967 Sprint (VLB)
I have one of these engines in my GT and have had a few probs getting the carb set up, what jets are you using? i have a 160 air jet, be3 atomiser and 102 main, there seems to be a slight problem getting it to rev out in top gear, any suggestions? |

I don't know what's in it yet ! I've literally just taken it out of its box and fitted it into the frame. When I find out I'll let you know. |

Be carefull, mine was jetted quite low and the timing on mine was set to the A mark (23 degrees) where as it should be on the IT mark (21 degrees) |
