ok im back to bug you guys and pick ya brains

what i want to know is what would be the lowest flow rate injector
that you guys know of

Have a look at the following sites:
http://users.erols.com/srweiss/tableifc.htm
http://www.fuelinjector.citymaker.com/p ... 782443.htm
http://www.autospeed.com/cms/article.html?&A=0102&P=1

It looks like the old 1.8L Holden used about a 16lbs/hr, and Hyundai's about 14lbs/hr.
There are some listed on the site that go down as low as 9lbs/hr.

How low do you need to go?

how low im still dont know

i have a old wolf 2d ecu there fuel only and looking sticking it on
a 140cc pit bike so it's not going to be big

lol

i'd be looking at a motorbike TB with injector built into it .... something like this and just use one of them

yer im going to head out to the bike wreckers and see what i can pick up

but most i find on the net are like 34+ mm throat size
where the carby on the bike is only like 26 to start with
so 34mm may be a bit to big

possibly but also having a fuel injector to spray a nice mist into the air stream helps overcome low air speed issues a bit

dam bike wreckers is closed till the 4th

what would you guys suggest in the way of flow rate for the big 140cc beast

Half a pound per horsepower is a minimum. So a 14 lb injector would be enough for 28hp.

I would be hesitant about putting a 34mm TB on a 140cc bike. I had enough trouble with a 36mm TB on a 530 single. You will need a battery and GOOD regulator/rectifier if you intend to go for EFI. Does the magneto have enough load capacity to run the EFI? Single cylinder bikes are much harder to convert than a car.

Whats wrong with the carb?

If you can get them running right they can be a good thing. Would love to see some pics if you get it going.

been doing a bit more reading on injectors and i made some ground


GONZO
when it comes to the power thats still up in the air
from what i have found out the older type stator should with a better reg.
but as it is no longer used some say im out of luck

and well there is nothing wrong with the carby new bike
with mini moto it all bling and wank factor
but there is a big debate on the best carby to run

so when asked what carby i run i can watch the eyes
when i tell them what i run for a carby

happy new year guys

if i was to drop the feed pressure of a injector from 36 psi
to 20 psi is that to big of a drop

if the injector is to big what problems will i run into


if i can get this set up cheap and nasty like
and have it run
