What are the advantages/disadvantages of a lightened version?

a heavy one will be like a steam engine ---big slogger,a light one will be like a race set up ---less drag quicker accelerating,less guts up hills,

A heavier flywheel will also give a more even tickover. Lighter ones can struggle to keep it going and you,re constantly blipping it to keep it going.

put a full weight long finned indian flywheel on the Special , and its a lot better , 2"s up, and easier to pull away loaded up without slipping the clutch like crazy. the light AF one ive put on the GP which has a revvier engine and a single seat . depends on the engine and what you use it for.

midweight..

i had problems with both AF lightened and midweight - issues with firing points etc

so i now lighten genuine SIL flywheels to the elemec midweight dimesions and they have been great (I have 2 on bikes and 3rd ready to be done) striking the balance with the issues associated with full weight and full lightened.

Just done one ofthe old heavy px vespa ones with a nylon fan - but brought it in a bit heavier than the current disc type - again a nice balance

gaz

Anybody tell me who sells the sil mid weight flywheels please.
Thanks
Ian

There is no SIL mid weight

AF (and others) sell the mid weight made by Elemec

i just bought a genuine SIL and lightened it to the same dims as the Elemec

Are they good quality ?

Bought one from Beedspeed. No problems at all and many miles done!
