New condition, came in the OEM box and only used once to verify it lit up and menu appeared. $120 shipped or $110 local/Denver. PM me and Ill get back to ya as soon as I can.

Make me a decent offer and we'll play pawn stars. No longer needed with the new scoot that's carbed.
-
Where were you when I paid my dealer over $200 for a new one? Good price for an essentially new scanner! Keep it for when you get even a newer bike with EFI.

I'm sure an offer like that will get scooped up quickly. Good lookin' out 2Wheelin.

Can this be used to de-restrict a fuel injector? Just curious, I suspect somehow my fuel injector is limited on my kymco 50i
-
There is no ecu restriction that can be changed :/
-
Pull out your injector, and verify the make/model. There are specs on every manufacturers web site that tell the flow rate for any of their parts. You can go to a higher flow rate, and modify your air box/ exhaust to keep up w/ it. The ecu will simply monitor the A/F ratio. Not the amounts.
I'd love to get my greasy mitts on one of those bikes. 8)

I just don't imagine the non-restricted 50is act like this. With smooth boss and no throttle screw it struggles to go over 30 mph. It seems to have less acceleration than with the restricted boss. Basically if there is no cdi limiting or fuel injector limiting, i need to find a way to get more power.
If you went to buy an unrestricted one of these and it acted like this you would not buy it.
They even advertise this as "Motivated by an air-cooled 49.5cc engine that delivers enough power to safely traverse the surface streets of any community", well in my community it struggles to go up hills at 28 mph and pisses off the cars behind me.
-
DOT laws in the US, and Many other countries demand that a 49cc bike is not capable of more than 30mph. It's just the way it is.
The reason you felt better accel from the restricted boss is the lip on it kept the bike in a constant lower gear ratio. Yes you are correct.
The "restriction" of your machine is in the injector flow rate, and the Ign timing curve.
Two things you can do. The first is in my above post, and the second is...
Contact Sutai. They make the CDI's for Kymco.
I had them custom program a CDI for me a few years ago. It's gonna cost just under 100.00 US but it was worth the money. I still have that CDI, and it still works.
The hard part is finding someone there that speaks English. I had to call 1/2 dozen times till I found a fella that understood exactly what I needed. I needed a Tech, and kept getting secretaries.
Barring all of that... You could always swap out the EFI for a 24mm Carb., and any good CDI. I would think 250.00 for all of your EFI parts would be a quick sell on the forum. DIBS!!!

Thanks, Zombie, sorry to derail the op post.

I've derestricted like 5 or 6 59i's, after the boss and throttle screw they did a very solid 35 on dead flat, 40 with a slight downhill. Is a 49cc tho, uphill is going to be slow. If you get 28 up a hill that's AWESOME!!! Idk what kind of hill you have around there, in Portland my zuma constantly slows to 25-28 uphill (light mods). The main restriction on the 50i is the throttle body, it's prolly 15mm max! And zombie, it would be some serious work to convert back to carb everything is tied into the fuel injection. Cdi built into the ecu, you would need a new flywheel, carb, cdi.... Not impossible but very deep.
-
Maybe since its cold and new scoot with 40 miles it is a bit slow and will speed up to 35-40.
-
All the ones I have de-restricted had less than 100 miles on them......

have you sold it yet? 120 shipped sounds good ,. de dee

Why would you need a flywheel?
Ebay carbs, and CDI's are under 50 bucks. I'm just thinking out loud because I have never even seen one of these bikes.
-
Have you seen the flywheel on the efi Kymcos? They have multi-pickups and you wouldn't be able to use this as a reliable source for the standard pickup coil, not easily at least. Anything is possible, but it would be a bitch to go back to carb on any of these. If you got a really high end ignition setup then it might have parameters for multi pickup but then your looking at what, like $600 for ignition alone? Lol then a nice carb $100~. If o was gonna go all out on a 50i, first thing would be throttle body and injector swap, i bet anything that'd be 50mph out close to it on flat. The variator needs to be researched, possibly the same as other qmb/kymco style idk. The exhaust is very tiny, the header is pea shooter size, same with the intake manifold. Idk all of that is so expensive, and the efi system would be totally custom after the fact because the kymco one has the ecu attached to the throttle body directly. You could go buy a crate qmb, 4v head, big bore, big carb, for the same as what I listed before haha. Realistically with what the Cimpagno has on it, you can expect maybe 45mph TOPS on flat. The throttle body is so tiny.
-
I never thought about the flywheel but now that you said "multi pickups"... One of them HAS to be a crank sensor so the ecu knows where the crank is in it's rotation.
That's how they establish a base line for variable ignition timing.
I still want one.

Anyone looked up a ssr piaggio 50cc. Those are fast............50cc scoots.

De dee sent you a pm.

The SR 50 has been on my X-Mass list for a few years. I tried taking a few "pot shots" at Santa this year but I didn't realize he has a Kevlar suit. ::)
Maybe next year I'll try a snare on my neighbors roof.
-
SOLD!
-
SWEET!
Who got it (so I can borrow it) ;)
-
I bought it , its 20 below here I will be there soon,.

De dee here's a link to the user manual, scanner didn't come with one. Vesbretta is to be thanked, you'll need to use firefox to access it. Don't know why IE doesn't work. http://www.enmoto.com/enmotoonline/downloads/Specifications/Kymco/Reparaturanleitung%20Kymco/Downtown_125_i/DT125_13.pdf (http://www.enmoto.com/enmotoonline/downloads/Specifications/Kymco/Reparaturanleitung%20Kymco/Downtown_125_i/DT125_13.pdf)

COOL! I'll have a pot of coffee, and a comfy chair waiting for ya! Glad to see the scanner found a deserving home.
