Absolutely nothing in the manual or injector markers... I am lost. Even the FAI website is no help! http://www.fai.com.cn/English/Product/
However I have found this: http://www.microsofttranslator.com/b...p270002144338e
Even in the diagram there's no fuel pump present I am beyond confused! However... http://www.fai.com.cn/English/Techno...04-30/105.html
this says it pressurises the fuel in the injector...??? Thanks for all the help so far lads!
Interesting. The animated gif does indeed look like the injector compresses the fuel. Quite clever, if it works.Quote:

Once everything is hooked up, this is when you ask for your friend's help (make sure it isn't a good friend ... maybe just an acquaintance). Hold your friend's beer, you step back about 5 meters, and ask your friend to turn it over to see if it starts.
If the bike starts without bursting into flames, maybe then try routing the return before/after the filter (it probably doesn't matter). Finally, while again holding your friend's beer, see if the return routing results in the bike continuing to run. If so, congratulations!
Anyway why are you going to all this bother to convert your bike to EFI ?
As far as I can see the only reasons to go through all this hassle is make the bike conform to some emissions standards or to increase power. If you want to increase power it would be a lot simpler to change the carb, fit a high flow air filter and rejet the carb, fit a performance camshaft and the best on of all is just to fit a bigger engine.
Already done everything for power,Quote:

The list goes on... Sadly I'm an addict of tweaking, it beats masterbation. Plus I get to learn things in the process. Every car I have owned I've had to touch but this is my first EFI conversion, its the last step to maximising performance due to the limitation of a carb. I have also bought a data cable for this ECU, I'm hoping to gain access to the ECU at a later date and maybe get a friend to help me tweak it on a dyno providing he has time to help and I have time.
