Super Dio ZX AF28 and other Dio scooters

if you try and get the elite s gears and get your gear ratio to 9to1 your topend will be better and not loose that low to midrange you like.that 8.25to1 gears,what was the teeth count on those gears?

Right now, I'm okay with only 55 mph with an unported cast iron since most of the roads I like to travel involve a lot of twisties.

I was using the Dio ZX 13 tooth primary drive shaft along with the 41 tooth countershaft (the large cog). So 13 x 41 for the primary gears.

The above was used in conjunction with the 9:1 secondary gears from vtcycles. The pressed on cog for the final drive shaft had 42 teeth and the countershaft (smaller spindle) had 16 teeth. So 42 x 16 for the secondary gears.

I only hit 51 mph with that setup since I didn't have the power to 'pull' the gears.

So, is 55 mph 'normal' for a Malossi unported cylinder with PG Typhoon pipe?

with the 9.7to1 gears thats pretty good.I bet your lowend is really good.it wheelies from takeoff without pulling the bars?

[sanjuro]

The low end is excellent, but I'm too chicken to lean back on the end and let it do it's thing. I didn't get the feeling it would pop a wheelie just with the throttle. Also, I think I'd have to tune the transmission since I'm using the Malossi Delta clutch in it's 'factory' settings. There is a slight lag, and then it engages.

yeah tighten it up more but if you don't like that high stall and then the hard grab,leave it how it is.not everyone likes that high stall.

Dumb question, but how do I 'tighten' it up?

Also, I was riding some pretty high elevations today, and the bike felt like it was cutting out at full throttle. I have a Posh CDI on there so the limiter was not kicking in. I'm guessing my float bowl is adjusted too aggressively and that the bike is starving for fuel at full throttle. It seems to happen when I hold it WOT for longer than 5 seconds. Could it also be a soft seize occurring?

The higher in elevation you go the thinner the air gets so your jetting will get richer.I bet the plug looks dark.

Last summer i only hit 61.3 using an R1 pipe with 8:1 gears and very mild porting on cylinder. more porting and pg long really opened it up. That and the mini-stroke.

[sanjuro]

Yeah, I think I'm going to upgrade the pipe very soon. The problem is I don't want to get too high revving of a pipe since the cylinder is unported and doesn't rev that high.

[sanjuro]

I had put in a new plug before going on the last ride. Here are some pics. Should I go higher or lower on the main jet?

[bakaracer]

the picture is a little blurry on the plug but the first pic looks like its running rich and the second looks like its ok.Is it dark on one side and ok on the other?what does the inside on the porcelain look like on the bottom?is it dark all the way down to the bottom?

[sanjuro]

Is it dark on one side and ok on the other?what does the inside on the porcelain look like on the bottom?is it dark all the way down to the bottom?

It's uniformally dark all around. The top eighth of the porcelain has a slight brown color to it, but the rest of it below is a dull egg white. The outside thread color is a cross between the 1st and 2nd pic.

[bakaracer]

If you look at the base of the porcelain,is there a smoke ring and what color does it look like?

[sanjuro]

Yes, there's a smoke ring at the bottom, and it's a slight brown color. It's really hard to tell since the inside of the spark plug at the base is fairly dark.

[bakaracer]

use a flash light or bright led just to make sure but if the smoke ring is brown thats good.try and take a clearer pic of the ground strap part of the plug.

[sanjuro]

Ok, will do.
