The obvious and visible immediately is the thickness (diameter) of the handlebars where the gearchange and switch housing meet it.

Re: Lambretta Rear Brake Adjuster

ALL it does is stop the knurled knob un-adjusting by keeping the barrell part (that sits in the arm) pushing under pressure against the curved recess in the adjuster (knurled knob). In theory (and someone must have practical experience of it), without it, as you release the brake the adjuster could ...

Re: Chain tension and scootopia chain

Hi Fluff, besides your new chain, are either the front sprocket or crownwheel new? Or from the original/ a different engine? There are some awful versions of both out there, either slightly over/ undersized and I've seen both sprockets and crown wheels machined off centre (eccentric). Your original/...

Re: LCGB - BLOA - Concessionaires......confusion
