just got it done today. chugs along while hauling butt.
Is that using a solo pulley? Bravo!
variated two speed?
close up of the Solo Pulley.
Someone did a MARS/Solo 2 speed pulley on a Peugeot 103, but said it wasn't that great so fuck it post a video !!!!
i should of made a video today but will tomorrow in the light. Best I can tell is that 1st gear is underdriven while 2nd gear is 1to1. With the solo's pulley being a little smaller than the stock moby pulley it's second gear makes higher mph than stock. 1st let's it pull harder. It fully variates before shifting into second thanks to some atf in the solo's pulley. After it shifts it un-variates and starts variating again. It variates at too low an rpm though. Do they sell lighter balls for the stock variator or do i have to drill tiny holes through them and fill the holes with plastic? I don't want to go with a stronger spring as it's not slipping the belt at all and I don't want the extra drag.
The driven pulley has a planetary gear reduction inside it, so the variator drives the 2 speed pulley.
You can get a 4 ball roller guide for it.
Stock should be a 3 ball roller guide. By getting the 4 ball guide you can use just 2 of the balls instead of 3 or 4.
I know on a Peugeot I can adjust the weights easy, but I've never tore into my Moby vario yet.
i want a vid
Now port the shit out of it and dail in the vario and go really fast. This was on my "to do" list in my long forgotten memory. Yay!
sick... Why haven't I heard of this before?? Vid please.
If you could take the pulley apart you may be able to put stronger springs in it so it would engage later at higher RPMs
(Kinda like a Doppler clutch pulley).
You can also tune the Moby Vario or swap it for a performance vario so you could tune it in to variate when you want it to shift.
The Solo can spin some good RPMs even though its all plastic gearing in there so you would want your vario to to spin the shit out of the pulley in the second gear before the Moby variates the second time. I know that the 1st gear on the pulley is kinda short and not sure how to make that rev out more unless the spring adjustment would do it.
Bump for a Video
This is so fucking rad, I don't know where to start.
Aaron is right, by the way. I'd just take the plung and get a simple Varplus. Cheap, great performance, and very, very tunable.
Don't drill out your variator balls! That thing isn't a Hobbit or Derbi!
congratulations on your successful build
well it was a colaboration between me and a friend. It's going to find a home at mopedless girl's house. I'm going to go make a video.
That is awesome! Much better than my foot shifting moby!
Hey, are you still rocking the stock moby variator? If so, is it three or four ball? If you want to cheat, and it's a four ball, you can remove two to lighten it up. Otherwise you probably ought to just switch to a varplus to get the shifting rpm perfect.
that is very impressive man.
im happy because of you ingenuity. was it a bolt on deal?
Been looking for one of those pulleys for years..
Seems to me you could get what you want just by changing the sprockets. Smaller in back or larger in front
thats cool that works!
is this real life?
to answer a question, yes it's just bolt on. The moby and solo's pedal shaft is the same diameter. We used the moby's pedal shaft with the circlips and crap. I think we tried the solo's shaft and the pedal sprocket didn't line up with the rear. We had to go to autozone and get a new belt as the solo's pulley is smaller in diameter so the original belt was too long. They were cool and let us bring the bike inside while they pulled what seemed to be a million different belts out for us to try. Aside from the solo's pulley the moby is almost stock with the exception of a pug's stock carb and a cylinder from a unvariated moby. I think I may have trimmed the piston skirt, drilled the intake, ported the intake slightly and intake to cylinder matched it but i don't remember. This engine sat on my shelf for a year with no one wanting to build the bike so we sand blasted and acid sprayed the frame for the rust and chrome look. The pins on the variator or catching the belt sometimes because we made new rubber mounts out of stoppers from lowes and apparently they are way too soft of rubber.
wow! thats is amazing and ingenious! i wanna do it!
