EFI Conversion kits

Anyone know if any EFI kits are yet made in china or exist on tadbao?

I've found two websites that produce a kit but they are originally made in china and they are asking for around $300 from us or canada depending on website. I'd love t give it a go but I'm curious to see if anything is out there in china, I know human is usually good with finding things.

They do look promising.

Did you realize that "humanbeing" is actually a robot with a supercomputer brain? He just toys with us by calling himself "human"

Anyways, agreed - an EFI kit would be interesting. I always wanted to get one for my old YBR125 - the YBR125s sold in Europe have EFI, but are carbed here.

OK, I'm contemplating about changing the CV carburetor of my Beta/Suzuki DR with a flat side one (and possibly sticking in a big bore kit), but these options sure seem more exciting.

Do these listings say something about changing/adjusting maps?

I'm sick of carbs, jetting with each mod and I do miss injection I had on my ybr125. So now I'll have 156cc, higher lift cams, plus all the other mods I think this would finish it off going to place an order tonight.

Have a read, its not too helpful, but you have an independent ECU, with a closed loop system that links to a laptop for diagnostic purposes whether the map and be reconfigured.... well I can't see anything explained, human might have some idea with his 100Ghz CPU which is able to provide instant help.

CG change EFI must first overcome the problem of electricity

Most of the original CG engine magnetos serious shortage of generating capacity. Just to promote the EFI system there is a problem

Must replace the 12-pole or 18 and Magneto. Rotor must be replaced this part will have to spend about 150

Battery problem is a big problem too old 12N7A CCA. Launched a few very easy to get the battery runs out

EFI set of approximately 690. Containing negative pressure sensor. Again is EFI parameter values of this part is like the same tune the carburetor

Just become controlled by the ECU. Which involves many complex formulas this part either friend to help. Otherwise even launch

Is a problem. Now transferred to the basic can ride, but there was still stalling phenomenon .. If you want to adjust to perfection must have a sense of control of oxygen transfer

In order to achieve perfection, but really too old CG architecture. Limited effect even hang EFI

Personally do not recommend CG change EFI ...........

Very interesting, the power supply is poor I'd agree there, I have lowered power consumption on mine a tad by replacing some bulbs with LED versions, such as Speedo etc where supreme brightness is not required and merely just requires illumination, but its good to know the map can be configured. But he is using it from what a can tell a OHV engine whereas I'll be doing it on a OHC engine

Agreed, very interesting. I had noticed that a guy was selling upgraded stator kits (plug & play) for the YBR125, and I bet they were OEM parts for the European-bound, EFI YBR125s. When I was having stalling problems with my EFI JH600, every buddy back home I emailed about the problem said "check your electrical connections, make sure your battery is 100%, and measure for sufficient and constant voltage." In fact, our own Franki was the first to give me that advice for my JH600. Seems that EFI is very finicky about adequate (and consistent) power supply.

I know what you mean, I had a new ybr125 from the dealership. Brilliant bike would do 80mph all day long even on inclined roads, problem I had was lack of upgrades for it, so I contacted the USA as the Tuning scene is bigger but no one could help as they still release the same bike but with carbs and nothing was available in Europe. Will order a 18pole stator on a new post hopefully human can help as taobao still confuses me due to know knowledge of Chinese

Right, I got the kit, manuals in chinese and black and white... This should be fun!

Human, do you know if I can get software and a USB or COM cable to that ECU to make some minor adjustments?

Looks like a company in the states uses the same kit, just they have the ECU connection incorporated into the loom, like so:
