MOPED ARMY

Not sure if the rubbers make a difference, but er3 doesn't have any.

My blaster 50cc variates the 1/4” nuts too easily, even with the polini motor spring.

I'm in love with this. The pics used to be broken, and I had to figure this out on my own already. But I still enjoyed reading it. Good on ya.

Now let's talk spring/gas shock mods.

That spring seems way too soft?

mono shock from pit bike?

that monoshock is on hobbit cases.

so sick. thats whats up johno.

Sick. I'm inspired. I'm looking to build one of these this week end. I just need to source the gas shock.

charlie.. check out mc master carr.. thats where i got all my stuff.

email me if you have questions

the guy at my belt shop said he saw no gains over the power twist.

you actually get less surface area on the cheeks.

a slotted v belt is the best.. you get as much contact as you possibly can.

regular old v belts are just fine too.. but you dont get all the contact you could.

yeah those gas struts are cheap at autozone like 12$ for a 40lbs one

charlie do it

Bump.

1/4" nuts (about the same as 6mm nuts) works perfectly on a stock 50cc top end with the exhaust lip taken off like this guy did:

I had bad variator bounce with the 1/4" nuts. I like dropping the weight, but a stiff spring makes a big difference.

After getting my vario to shift when i want with a polini spring i find im thrashing stock clutch discs.

First the numbs all break off then finally just splits in two...

is there any other option for a clutch other than a clutch pulley? sooo expensive and i have read that they glaze up pretty quick anyways so still not super practical for a daily rider.

I have been thinking about go kart clutches, or maybe doing something with the starter shoes and use a pull start? what have you guys figured out of the years?

So that uses no stock clutch and no clutch pulley?

i have the pull start set up already but im pretty sure a buddy of mine had one of these back when, he would just fold a piece of cardboard and jam in in the belt and pulley to start it up.

I really need to figure something out, my bike is ripping really good just keep blowin' up my clutch discs and they aren't cheap.

The other option is to do a clutchless ER3 and run a belt that is a little bit too long so that it slips at idle. Might burn up belts a little bit faster though.
