How do you get the Lambretta shifting perfectly and smoothly
? We take a close look at the controls and what you can do from the headset to the cables to the gearbox pivot and selector lever on the engine casing. Let's be honest, the last Lambrettas left the Innocenti factory half a century ago. And not all of them were regularly serviced and maintained as they should have been. One of the many beauties of Lambrettas is that they are very easy to work on, especially with the right tools. right toolsthe the right parts and the right instructions(sticky). There are three areas to look at:
Handlebars / Headset
cables
Power unit housing
Handlebars/Headset
Within the Li family there had been various changes to the internal parts of the headset. On well-maintained bikes, most of the time can be spent taking everything apart, cleaning it and putting it in properly greased and lubricated. Once you've done the job, it can't hurt to replace all the bushings in the headset. These are the guides for the shift and throttle rods. Available as handy sets from Casa Lambretta:

Cables and wiring
Cables with Teflon/PTFE lining are essential. These run super smoothly and are maintenance-free. The bgm cable sets are made specifically for the Lambretta Li family and have some unique features. The correct inner and outer cable lengths are guaranteed. Here you can find additional information about how good they are: cable-sets-bgm-pro-for-vespa-and-lambretta/. Back to the action: If you have routed the outer cables correctly, as shown on the bgm installation instructions:

Especially the lever screw, the pivot of the inner cable and all operating and moving parts must be well lubricated. 80082001906201919062021 Lubricating the inner cables with Teflon spray does no harm and, above all, operating the clutch is much easier: G280512Tip: If the bolts of the clutch and brake levers are not greased properly, they can wear out the holes in the light switch housing and the gearshift housing. These can be easily repaired with the oversized bolt: 8900009
Transmission housing
The most important thing is to avoid unwanted slop in the transmission swivel, latch rod change and selector lever. Fortunately, there are many different choices for everyone's tasting pleasure. Like the Casa Lambretta selector lever set manufactured to original specifications: 7676338 Or the high quality CNC machined set from bgm, made for us by JPP Tuning: BGM2290B Paired with the bgm pivots you really have a perfect and durable set: BGM6466 This is the complete bgm spigot set: BGM6465 For sure, the bgm pivots have the original 3.5mm hex key size as found on original machines as well as original tool bags that come with your brand new scooter: 33314758050083KT Something we didn't think was original is the epitome of customizing these. The bgm wrench is fitted with a ball head. This makes adjusting the shift pegs a breeze when you hit the clutch cable lightly: BGM6466TL Top tip: For all the rust freaks out there who want to keep their Lambrettas as original as possible, we have oversized pivots made for preserving worn gearbox pivots:
BGM6466P Due to the oversize, the pivot pins fit perfectly into used gear swivels. If necessary, minimally grind out new shift paddles. These complement the inner cable sets perfectly:
