Hi all.. Newby here... HEEEELLLPPPP

Hi All.
I was wondering if anybody can shed some light on a problem I have with my Bird..
I was on a ride-out yesterday (Ride of Respect) and my B/Bird just cut out on me leaving me stranded.. :violin:
There was no drama, not horrible noises/smells etc. it just cut out at 20mph, The engine turns over and everything works, but there is nothing, not even an attempt to fire up from the engine.:bang:
Has anybody had anything similar I was wondering, if so where do I start looking for faults, CDI unit seems to be favorite at the moment..

Cheers. I eagerly await your solution

EFI or carb?

 

[PeterT118]

HEEEELLLP

Carb.. sorry

 

[robsbird]

start at the fuel diaphragm..............

or the vac pipe has a split in it and not opening up to let the fuel in

@tu*

 

[PeterT118]

I will have a look, but I can smell fuel from the can when I try to start her, so I presumed it would be electrical!

 

[Duck n Dive]

Does it have an alarm system fitted??

 

[PeterT118]

Yes mate, it has a Spyball alarm

 

[robsbird]

there is the second places to look then......

pop HT lead off and put a plug in and see if you have a spark

when trying to start

@tu*

have you changed chain/sprockets lately?
If you pinched the side stand cable with the front sprocket cover it does wonderful things, had this on mine last year.
cutting out does not sound like fuel diaphram to me as you would first start to lose power with big throttle openings and it would get worse till almost any throttle would kill it. Plus after a few min it would start from the tiny amount trickling past into the carbs but would die again. Also had this )) Different birds )) both carb.
Vac pipe is suspect as a good diaphram will shut off any fuel.
not kill switch as motor turning over....
dissconnect alarm and try again

 

[PeterT118]

Thanks for all of your advice. I will look for cheap fixes first, vacume pipe and alarm (is it easy to disconnect an alarm?) I will keep you informed..

on my alarm I just disconnect the leads to the battery and bike works as normal

also dont go to honda for a new diaphram, is £35 odd when I bought mine last year, its cheaper to get a complete tap etc from fleabay

 

[PeterT118]

Right folks new information..........

I went out to the bike today with the intention of taking off the alarm...

Thought.. I'll just try to start it... .. It ran.... woohoo.... for 5 seconds then died again..

To me this discounts the alarm, the CDI unit etc, as it obviously has sparks.....

Sooooo is it the vacume pipe (which seems ok) or the diaphagm??

Answers on a post (card) please!!

P.s should I be able to suck down the vacume pipe (ooer missus) fairly easily?:-0)

 

[Jaws]

Depends on which end you are sucking !!

If you are sucking on the end that normally goes to the inlet manifold then nope.. Should not be able to get any air through it at all..

Nobby, if you buy a second hand tape there is nothing to say it will not either be on its last legs or in fact might already be duff.. when you are chasing down an obscure fault the last thing you need is to fir something you are unsure of !

And.... They aint ?34.00 any more. ?48.00 is now the recommended price from a Honda dealer.. I do carry them and they are ?44.00 ( again, genuine Honda )

 

[PeterT118]

Ok... I have had a go at sucking both ends!!! ahem!!!

I can suck the pipe to the inlet manifold and it lets air thru, but when I turn the engine over it sucks my tongue

I have also tried the other way (to the fuel tap), this also lets air thru..

Does this mean anything to anybody?? surely there should be a resistance/vacuum when I try to suck the fuel tap one?? as this should open the fuel diaphragm!

 

[Jaws]

Yup, petrol tap diaphragm is fubah'd big time I am afraid

 

[robsbird]

sucking the pipe up to the tank should open the diaphragm the let fuel past to the cabs

you should not be able to suck air so your in the right please

as the sucking should be pulling the diaphragm open

@tu*

 

[PeterT118]

JAWS.... Before I go buying one, Are you fairly confident that would be the problem?

 

[andyBeaker]

If you want to be certain - get a can of cold start and fire it into the air box and hit the ignition- it will fire up for a few seconds then die. This will 'prove' that everything is OK other than fuel not getting through.

Vacuum tube falling off is something that most carb owners suffer at least once (mine was way too short so made a longer one out of a spare tube from a Scottoiler so it didn't happen to me twice!!)

Diaphragms have been known to go so if it ain't the tube then it is very likely to be the diaphragm itself.

Either way, a straightforward fix@tu*

 

[PeterT118]

AAAAARGGHHHH!!!!

Ignore all that. I had put the pipe on the wrong bit (it was the petrol tank breather) I just put it on the right one and got fuel all over my arms... DOH!!!!!

So back to square one

I gonna get a new pipe as the one on it had a splitter going to an old scott-oiler

I will see what happens..

I'll also give dampstart a go as well and let you know

god wendy is that your way to fix every thing with cold start
