"one wire may be pinched and exposed somewhere, a plug in the harness might not be correctly making contact"

That'd be my guess. Something to do with the temp sender.

cool mate

going out to the shed now to get back into it

spent all day literally stripping black tape of all the wires from front to rear...

front

and rear

 

found one crushed spot

 

 

put it all back together, nothing changed....

still starts to sputter and then the CEL flashes on and off, goes into limp mode...

 

oh well, she goes of to honda methinks...

not sure who has read my thread, but i have been having issues for near 2 weeks(since fitting my mods)

all the symptoms seemed to me, like the 'overheating issues' or or something in the wiring i had done wrong since the fatty and stretch kit was fitted.

it had to be something i've done..!

it was running fine as a daily right up til the day i stripped her to prep for the mods..

i reset the ECU, tested the thermostat, any of the sensors, and finally stripped the wiring looking for a pinched wired, loose connection or anything like that, that i may have inadvertently caused..

all to no avail..

 

now, sorry for the long winded post, but now to the meat and veg of the story:

today i got to thinking..

my Zoomer has the PGIM Fuel injection, not a carby that most of the U.S modded ones use and Mojo Customs would expect

i removed the standard fuel line when i fit my fatty/stretch mojo kit and fitted the supplied fuel hose, went about the rest of the fitment

the black one is the OEM Fuel Injected line

the blue is the one that came with the kit, that i now have on her, similar outer diameter

look at the inner diameter..

so my question is:

 

i have a larger size fuel line on her, which means the fuel pressure would have to be lower than whats required for the fuel injection?

is that all thats wrong with my girl after effing around with everything else for the last 2 weeks?

going to bed to sleep on it

any input appreciated

thanks in advance

Are you sure its just not overheating because you have put a larger tyre/stretched frame so the engine has to do more work to turn the rear wheel.

Does it over heat when idling or only when under load?

You might find the larger fuel line is for the ones with the upgraded engines.

hi mate

thanks for the reply, yeah tried swapping back the stock rim etc to try isolate the problem

this error pops up after the first 'blaat' of the throttle, regardless of rim, or how long its been running, ie right after cold start, or it can sit and idle for half hour, no error(i did this to try bleed air ot of the cooling system), then first blaat' and bamm, error..

thats why i am now leaning towards fuel?

thoughts?

So is it actually overheating or just saying it is?

If fuel pressure was an issue you'd think it would manifest itself in performance not heating issues.

In saying that I have heard of some cars overheating with incorrectly gapped spark plugs.

 

Welcome to annoying electrical gremlins. I'll be your guide.

It could very well be the hose, I have no idea about how the EFI is run in these things.

 

Is the new hose much longer as well?

I would definitely try and move the tank or something to try the old one.

Doing some googling it seems low fuel pressure can cause overheating in bikes.

AUDM YO, it is about 4" longer, mate

and heya Reed, i really don't think it's overheating, just the display light is known as the 'engine temp light' in the ruckus scene.

going by what i can find on the Zoomer, of which mine is, it is more likely a 'check engine light'.

so i think it hasnt been overheating at all.

whether its after i recently starting it and not had time to get hot, or after its been idling and warm, i give it a 'Blaat', it starts to miss and fart along, go into limp mode, and i have merely seen the light come on, assuming it has overheated

maybe the ECU sensed the lack of fuel pressure, or the engine is leaning out now due to it, and the combustion chamber is getting too hot, before actually overheating, and it goes to limp mode

i did the ole skool fuel flow test, running the fuel line to a container and she gets plenty of fuel(more than 200mL/minute, but maybe not enough on demand?

i think these run at 43psi too, so the bigger diameter fuel hose has to have reduced the pressure?

will try find the right stuff from ENZED today

its a brainf#$k for sure

thanks for your input guys

Put a 4k in it.

haha...

omw to work then ENZED and Honda

will report back asap

Sorry i can't help with any advice but i can say this thing is super cool...seen it today & i think we need to get a 50cc cruise happening asap

 

i think we need to get a 50cc cruise happening asap

 

Probably be more interest than a corolla cruise.

 

Did the new hose help Zowie?

thanks DougE..!

and yeah agreed..! once she is running good, I'm keen. i know Joel has a few Z50 monkey bikes?

 

and no luck Reed....

think i have to concede defeat, and take her to Honda or something...

or you put a 4 k in it, as you suggested...lol
