Latest new toy fitted to the Lammy. I hope it improves the fuel consumption and slow speed around town running!

Happy birthday to me,

Happy Birthday Lucky sod

The Lamy's been running really well for the past year - so I thought I'd stuff that up by reed valving it
We'll see how it is when I get the engine back in!

I'd change that plastic float bowl straight away, as they distort after a while due to additives in petrol. I got an ally one off Martin (Corrado) at Just Lambretta. Dremel off the float stops in the bottom of the float bowl to prevent fuel starvation

So far it seems to be holding up OK (there, now I've cursed it ), but I've got an Alloy one just in case

Which reed block is that? Looks quite neat, did you have to do much to get it to fit, fettle fins, holes in piston etc?

It's the MB shorty and I think it's a nice bit of kit. You do have to do a bit of work to get it to fit ( well described on the MB tech website), but it looks like it will have good panel clearance for a filter. In addition to grinding the fins and the cowling (mandatory to get it to fit), I modified the piston (it's a mitaka from Ron Moss so I basically copied the pics of the TS1 version on his website), cut a boost port (the ring pegs of the Mitaka piston seemed very well suited to do this),
matched and flowed the new reed manifold and raised the exhaust port to give a longer exhaust duration.

Engine in scooter now:





Only given it a kickover to see it starts so far, initial impression - tickover much smoother with no adjustments!

New exhaust fitted



I like it!

Here's a pic of my new (with additional lightening by myself!) Atomic 47 tooth crownwheel from ScootRS, described as "lightened".
The standard SIL 47 tooth weighs in at 712g, the ScootRS Atomic even after my additional lightening ( I reckon I removed at least 30-40g) is 787g.
Still, it has fixed "the wobbles" (my original reason for replacing the SIL) and allows more room for extra plates or more movement with the standard setup to eliminate clutch drag.

Could you explain,what is the benefit of having a lightened clutch basket.
