Hello folks. This is about a small project of swapping the speedometer watch of my lml-select with an rpm meter. The watch inside the meter console was a simple wrist watch neatly tucked into the meter assembly. And replacing its battery was a cumbersome process. Hence I decided to do this conversion. Ripped apart the speedometer assembly, made a few holes to mount the rpm meter dial. There wasn't enough space to mount the rpm meter as one unit. So I split the circuit board and enclosed it in a waterproof Sealant mould. Since I took the rpm signal from the cdi high voltage input side, I had to recalibrate the rpm meter to display one-third of the signal frequency. Pictures and a video have been attached.

Unfortunately it lacks a parking light. And the entire reflector assembly is made out of metal like in the Vijai Super. True, it is unit of CNH. But you might have to confirm if this model headlight comes in the EU models.

I had paid about Rs 350/- (Less than 5 Euro) for the laser cutting & the little brazing work. I am more than happy to get more of them prepared. The shipping cost from India is going to be prohibitive against the cost of this ring itself. But if you could wait till the end of June, I could probably prepare a few and send with my brother who lives in Bochum. Shipping inside DE is not going to be that expensive. I shall look at the package or the purchase bill and share here in a day or two.

After searching high and low for a headlamp upgrade for my Vijai Super, I felt lucky to spot a headlamp from a New Holland 3630 tractor. The reflector assembly is of the same size of that of the Vijai Super. Took the plunge and procured an assembly from a New Holland dealer near my place. All I had to do was to devise an adaptation to make use of the this light assembly with the Vijai Super headlight ring. Took help from a friend who translated my paper cut model into a Laser cut piece. Did some welding and the final product was crimped to the 3630 reflector assembly. Will let the pictures speak about the details.

So, with you guys confirming the dimensions I was able to prepare a drawing and got a flange piece cut in a Laser cutting machine. Also I got the centre flange removed from a brand new 2.15x10" rim of a Honda scooter. Will get the welding done over the weekend. Before which I have to prepare a fixture that holds and aligns the centers of both the rim and the flange while welding. If you had been wondering what could be the white material covering the 3 holes around the splines of the brake drum, they are wasp nests.

Thank you very much. The difference is 1,5 mm. Yes but still it is a lot, because the load on the tyre would be going to the bolts instead of going to the brake drum. Actually I am looking at adapting a locally available 2,1 - 10" rim of a Honda scooter to my Vijai Super. Hence wanted to confirm these values.

Dear Folks,Has someone measured the rim PCD and the ID of the 2.10 - 10 rim that fits a Lambretta.My vernier reads 224mm centre - centre between the diagonally located bolts in the brake drum and 200 mm across the landing area where the rim rests on the drum.Please correct me if the above measurements are wrong.

If you are not in a mood to open up the flywheel and swap a stator plate, you can very well use a 4 pin RR unit of any Honda scooter. Use the brown wire from the generator to feed power to the RR unit. The output from RR unit goes to the battery. Are you running the blinkers with an AC flasher at the moment? I have my Vijai Super with full DC setup which includes the headlamp as well powered from the battery.

Hi, A brown wire from the junction box carries 12V AC from the Stator - Rear Junction box - Front junction box - Ignition switch. In all the above cases if the horn works, then there is no problem with the Stator and Rear Junction box. At position 3, use a multimeter or a test lamp to check if you get 12V at the orange wire from the ignition switch. If you don't, then the switch is the problem. Try a few liberal shots of WD40 into the key hole and twist the key through all positions and check for contact again. With a small piece of wire try to connect the brown wire & orange wire at the junction box terminals. If the bulb & the horn/dipper switch is good, the headlight should glow. If you doubt about the horn dipper switch, pull out the orange wire from the ignition switch and touch the bullet terminal on the terminals of the bulb. All the above tests assume that there is proper grounding available for the headlight.

HI, Could you elaborate the problem you are facing? Please click the link below http://howomg.com/wiki/vespa-wiring-diagrams/ and check the wiring diagram for Vespa 150 Super VCB1 http://cdn.howomg.com/wp-content/uploads/2007/08/vespa-wiring-diagram-150sprint11.jpg -Ilango

Hi, I understand that there is a play in gear shifting and you need to rotate the shifter more than before. I have a Vijai Super and this is how I would do. 1. Check for a broken Nylon bush or cotter pin inside the rubber grip. http://www.lambrettaspares.com/spares/headset-spares/handle-bar-(headset)-throttle-and-gear-rod-bush-for-indian-rods,-5mm-roll-pin/mbl0623.html Typically we weld the rod with the gear selector support like in Li150 2. Check for Nylon gear pulley for cracks or breakage http://www.lambretta-teile.de/Gear-pulley-plastic-white-Scootopia-Lambretta-GP-dl 3. Check for wear out in the shifter arm where the tie-rod is connected http://www.scooter-center.com/product/8104420/Gear+selector+arm+SIL+Lambretta+DL+GP?lang=en 4. Check the T-pins for any wear (you need to open the gearbox and hence this is the last thing to doubt) Hope this helps. -Ilango

Thank you for your replies guys. I live close by an Industrial estate where I have access to these stuff at wholesale (Grosshandel) price. Industrial Hydraulic & Punematic fitting come with NPT threading. That's why I had to improvise this. At the current exchange rates from Euro to Indian Rupee it worked out like less than an Euro for the plug & 1.5 Euro for the threading die (Schneideisen). Hope it made sense why I didn't buy it online and import it to India ;)

Fitted a Glass Oil level indicator in place of the Steel oil level nut. It was actually a 3/8 NPT Hydraulic fitting, which It had rethreaded to M16X1.5mm. Added pictures.

Dear Friends, I am from India (Pune, a city near Mumbai). I am guiding a colleague of mine (for his MS project work) in adapting a GDI (Benzin-Direkt-Einspritzung) system. The engine taken for experimentation is from a fully rebuilt SIL Vijai Super (Indian version of Lambretta GP150). At the moment he is in the phase of developing CAD models of engine parts so that he could analyze the feasibility of mounting injector, high pressure pump, throttle body and a crank wheel for crank position sensor. In the interest of saving time and focus on the actual theme of the project, I request if anyone of you could share the full or part of CAD models of Lambretta engine parts. This could greatly save time at his end, and I am also eager to see a full working Lambretta GDI. Any help in this regard would be greatly appreciated. Please feel free to discuss more or comment on this. Thanks in advance. - Ilango Note: Language is not a problem as I can understand German language to some extent. I was in Siegen between 2003 & 2006 for my studies. This interaction could help me recollect my German vocabulary as well. :)

Hi Fellmann, I have 2 SIL made Vijai Supers. Vijai Super is the name given to GP150 or 150DL in India. Till 1984 it came with the fixed mudguard as you see in the European market. Later in 1985 they launched the same scooter (rebadging it as Vijai Super Mark-II, as seen in my profile picture) with movable mudguard, Indicator lamps (though it was optional), and a different set of 2,3&4th gear ratios. I have a 1983 Vijai Super and also a 1985 Vijai Super Mark-II. The 1985 mark-II was bought new by my dad. I bought the 1983 Vijai in 2008 and did a top-bottom restoration. With a little increase in the compression ratio, and a Mikuni VM24 carburettor (from Royal Enfield bullet 350cc) it can take me till 100kmph. It still runs on points and condensor, and is my daily runner between home & office. I have done 8000Kms so far. Planning to put up a CDI with a variable timing. SIL also manufactured Lambretta Cento - the 100cc 3 gear scooter. -Ilango

Hello Marcus, Why would you want to take pains in importing a scooter all the way from India, while you can grab a good one from Europe? You will have to spend more on shipping & customs duty in Deutschland rather than the actual cost of the scooter itself. Secondly the Indian imports would be available only with a GP200 engine & relevant parts. Where as you can have plenty of tuning options rangineg from 175CC up till 225cc or more in your place. I would personally prefer to buy such vintage collections only after personally checking & test driving. The Vijai Super I have, was bought from its third owner only after I had a test drive & convincing myself about its condition. Happy Scootering!!! -Ilango
