i recently was asked about vario tuning for peugeots. it is a pain in the ass but can be done. and can be done well with a little effort so here ya go
you will need
bench vice
phillips screw driver
cressent wrench
drill
dremel
and a marker
1. remove your variator from the bike. if you dont know how this is done stop now and learn how your bike comes apart
2. disasemble the clutch put vario in the vice, remove nut which hold the vario togather disasemble the vario
3. now using the phillips driver remove the weights
4.mark out how much meterial you want to remove start with small amounts then get crazy
5. i also drill holes in the lead weights
6. use a scale and make sure the 2 weights weigh the same
7.you can see them side by side to see how much i remove
just so you know this vario will NOT start to shift till about 25-35mph so make sure you can spin the rpm to shift it
also my spelling is horrible sorry for all of the typos
hope this is helpfull to the poor people of the world
