A cheap ZX rear pulley, super common.

[LMH]

All GY6 chinese bikes have them, not only that but they also have a larger variator than the dio. As far as Ive seen all 139qmb variators, drive/n faces rear pulley and clutch, belt, and rollers work on a dio. The transmission part is another story, that is for the zx50, its a duplicate of the zx gearing. If there are after market gears for them they "should" work for the zx. Later on if I get time I will remove the gears from a spare gy6 laying around to verify. But certainty on the ZX rear copy.

Ive found rear pulleys from a local scooter store owner for 10$ each, I bought 6.

watch out those chinese ones may crack easier. id rather get the sym dd50 trans over the chinese gy6.

Like I said, cheap. 10 bucks each cant complain. I have 4 extra kymco zx50 pulleys but couldnt pass up the deal. Its nice to be able to put 5 different contra springs in 5 different clutch set ups and test them out for fun.

[paulpauly7]

your right there i have 4 rear pulleys each with a different contra springs it makes trans tuning much faster

If you run cheap parts i have the right to dog you out, if you run quality parts like i do you gain my respect.

I guess some people cant read, it says cheap not expensive or great. Idiots cant read its not my fault.

what 4 contra springs

stock, 1k, 1,5k, and 2k?
what is the cam profile on these Chinese pulleys?
Do these rear pulleys twist as they expand? or does it come straight out and then twist?

[LMH]

Its the same as my zx pulleys, twist out. I can try to take a side shot of it later on this weekend.

Hey Maddog
