Super Dio ZX AF28 and other Dio scooters

Fired her up for the first time in months and almost forgot how quick this thing is. Current jet settings are 35 pilot and 155 main jet. I don't remember the front end lifting from a standstill, but it readily did it this time around.

The only issue is the back wheel/tire looks wobbly when I rev the bike on the centerstand. I had replaced the rear tire, so now I think either the rim is out of whack or the final drive got tweaked some how. I'll swap out the final drive spindle tomorrow, and see if the problem still persists.

check to see if the bead set good. if your using the dunlop tt92 tires,they tend to hang up on the inner lip of the rim.

Ok, I'll take the wheel/tire back in.

[bakaracer]

you can just check it by looking at the sidewall.there is a line right by the lip of the wheel on the tire and should have a even spacing.if the tire is not seated right,that line will be at the rim lip or just slightly away from it and when you spin the rim you can see if its even or not.real easy and you can do it yourself.

[sanjuro]

It looks uniform to me. I just pulled the final drive and gears just to make sure all the bearings were good, and I am going to test fit another final drive in the morning. I hope it's just the final drive and not the wheel getting torqued from the wreck.

Also, was thinking about swapping in taller final gears since the transmission case is open.

Another thing, I have the idle screw set to 1/2 turn out. It won't idle at any setting greater than 3/4 a turn. I figure I need to up my pilot jet since it's just dying on me right away unless the idle screw is in a lot. I've read in a few places that a 45-50 pilot jet is good for a 24mm carb.

Where can I get one of those burial pipes?

what do you have the airfuel screw set at?

That specific 'EuroBlazer' pipe is out of production, but they have others you can buy at:

what do you have the airfuel screw set at?

2 1/2 turns out.

[bakaracer]

ahh yeah then yes you have to up that pilot jet.with the cooler air during the fall/winter,the carb will run leaner. try pulling the choke on to see if the bike idles better just to make sure that the pilot is to small.

[sanjuro]

Just redid some settings on the carb, and will fire it up later to check the progress. As it stands now:

45 pilot
155 main jet
air fuel mixture screw at 1.5 turns out
idle screw at 1.25 turns out

...and my rear wheel is tweaked. I replaced the final drive and still have the slight wobble. Tire looks uniform around the wheel lip.

Thats so nice

Looks better than ever

Greetings:

Nice job, Sanj. Is that a current pic? How'd you obliterate the background?

If you're still running that TM24 Mikuni, you may be close on the jetting. I recall a Pilot in the high 30s-low 40s range and a Main about the same. Temp gauge installed? Watch it for temp increase when you close the throttle. If you see none, you can try downsizing the Pilot a little at a time. I agree with Bakaracer; if it gets cold, be careful downsizing the Pilot and Main. Cooler ambient temps and fan air don't compensate for the leaner mixture being burnt. It's counter-intuitive, but colder weather makes the engine run hotter.

[sanjuro]

Yep, still running the TM24. Right now, I'm really happy with it since it idles better than before, and the front wheel lifts an inch or two from a rolling start even at 15mph without pulling on the bars or leaning back. I don't dare pull the bars or lean back from a standstill because the front end will come up quick in fully wheelie mode.

I build web sites for a living, so work with Adobe Photoshop and Illustrator. You can get rid of the background in either program using the 'pen' tool. It's not a quick process like using the 'magic wand' tool in Photoshop, but it is clean and precise.

[bakaracer]

Bike is looking good!!!! The usual Sanjuro builds,clean and nice.

Back in July my Dio sustained some cosmetic damage from a wreck that a Toyota Tundra driver caused by turning left in front of me. Well, I have her all back together and she's running beautifully.
