Super Dio ZX AF28 and other Dio scooters

32to1 is ok but to be a little more safe 30to1 or 28to1 but you will have to rejet if you change your mix ratio since your jetting now is to the mixture you have now.

So that means I will have to lean out the jets with a higher ratio?

If you go 30 or 28:1 then you will need bigger jet. You're running the ZX trans right? If so, what roller weight are you at? Just curious of a baseline for mine.

[sanjuro]

Oh I see, a higher a ratio of fuel just means I need to richen up the jets more.

I am running the Malossi variator which came with 7 gram rollers. My whole transmission setup is Malossi except for this thing which is the coolest thing in the whole transmission:


Malossi variator
Malossi kevlar belt
Malossi Delta clutch
Malossi wing bell
Malossi torque converter
Malossi torsion controller
Malossi white torque spring (1000 rpm)

Yeah, if you add more oil to the fuel you are taking away that amount of gas (which does the cooling). Then you need to up-jet to get the same amount of gas as you were before adding more oil if that makes sense. How much is that torsion controller and where did you order it from? I was going to get one from Roselle imports but i'm still waiting on my 2 sets of rings that were paid for on march 8th . Makes me not want to deal with them anymore.

[sanjuro]

You too? I'm still waiting for something I got from them

The torsion controller composed of collar and bearings fits over the driven face and there is the separate one (Malossi) that goes in between the torque spring and clutch. I just wanted to clarify the item pictured above goes on one end of the torque spring, and the Malossi plastic piece goes on the other end. So you end up with two friction reducing pieces where the spring doesn't bind at all.

It is made by Chameleon, and I picked it up while visiting Japan last October. It was $48 IIRC. I can probably get more if there is a high enough demand. Otherwise, the shipping for one just isn't worth it.

if your running the roller bearing spring saver,don't use the malossi plastic spring saver.the spring will bind when the rear sheave is trying to open all the way.the roller bearing one is all you need.

[sanjuro]

the roller bearing one is all you need.

Cool, everyday is a learning day.

Greetings:

I ran a roller spring saver in Flashes 1-3. Search MadDog's free part. I just omitted it in 4's ZX pulley, not convinced it helps performance at all. Its thickness adds spring preload. I have not carefully measured if it keeps rear pulleys from spreading all the way before spring binds. It might prolong spring life?

I use both also but I grease the Malossi plastic spring saver at the same time with good synthetic grease.. good thing I seen this it reminds me I have to check it and make sure it's still lubed and no wear is showing .

I just got back from a 11 mile break-in cruise, and the transmission definitely responds better with just the roller bearing setup. It was a lot crisper and accelerated better from 0-45 mph.

[sanjuro]

Today, my setup was a 40 slow jet and 180 main jet. I managed to put in a 22 mile break-in cruise. Everything felt the same except I got some of that 'on throttle' response again when I let off the throttle. It was very slight, and I'm wondering if the new spark plug I put in wasn't tightened enough. I would think my air mixture screw at two turns out is right, but I'm open to comments.

Also, I've only managed 35 miles on a half tank of gas. Not the greatest fuel economy considering it was light riding. I'm guessing my constant varying of the throttle killed the mileage.

[sanjuro]

Geez, I only managed 48 miles on 1.3 gallons of fuel:-(

Besides changing carbs, any way to get better mpg?

[veedubh20]

should try 28mm oko carb. 52p and main jet 142-148 1 n half turn out a/f

I have a Keihin PWK 28mm carburetor with a 50 pilot and 142 main jet. I need to order some additional jets, and a rubber adapter to fit to the stage 6 intake manifold.

put an airbox and down jet for the airbox. Oh and try and not grab a whole lot of throttle when stop and go riding.
