Project My Fizzer

Yea thats the plan .... I have an inline spark tester to try out ..... just sorting the tank after yesterdays out of fuel moment...... then I can do some running testing.

I managed to retreive the long internal filter but I think theres still a fishing sinker still left in there that must have got wedged somewhere from the last tank cleanout

Filter looks a bit sad also .... hopefully nothing has reached the carbs

 

Yea there was actually 2 small sinkers still in there .... they must have knocked out the inline filter to let the big lumps thru.....must have been all my Marquez lean angles yesterday sloshing the fuel about


I guess doing the tank liner is another one for the list.

Put in a new inline filter.
Checked the little filter that goes in the carby t piece inlet and there was nil crud.
Adjusted the clutch and re routed the cable.
Bent the gear lever outwards.

The batt earth to motor bolt is tight as **** ..... so Ill leave that cuz if it shears off Ill pour 10ltrs of BP91 over it and have a bonfire

 

Swapped out the black box
Tank FULL of fuel .... well nearly.

Battery 11.8 v at crank over
14.4 v at revs

Test the spark when its dark.

 

4x Code blue ....

 

heres my response a few posts back to the main earth lead.....

And the regulator was removed cleaned and 're earthed' during the rebuild

I attempted to sync before I had the airbox sorted so that needs to be attempted again ..... I only have little short crappy plastic adapters so Im going to get some long decent brass ones to make it a thousand times easier.

 

Now lets reiterate what my problem is, as I think with all the posts and my rambling posts and the off topic posts , what Im chasing has been lost.

The bike goes .....it starts first go and goes well enough out on the road ..... a proper sync of the carbs will help Im sure but it doesnt stutter, miss or have any noticeable flat spots.

The random thing it is doing (before and now after the carb rebuild) is that when u slow down to idle and stop , it stalls then does this ........ not every time just at random.
(this vid is from awhile ago but is exactly wat it did yesterday)



Now when u let it sit for 15-20 minutes or so , it will start normally and off you go.

Now to me thats something failing when its hot and after a bit of a cool down its good to go.... or something like that.

What would be interesting would be to test the spark straight after it has died.....but then if 1 coil was failing thru heat it would run on 2 cylinders and at least rev a little...... but Im just guessing.


Ive swapped out the black box but I cant test ride untill Tuesday.

I have a spare fuel pump I will try also.

 

Yea it does .... thats why I thought originally it was the carbys .... bowls not refilling kinda thing ......but they obviously have been totally redone and the floats are even from the spare set.

First thing I did when it did it yesterday .... no go.

 

Yea throttle does zero .... choke does zero.

The problem with squirting fuel into the carbs is that by the time you got to do that (tank off , airbox off etc) it would probably have 'righted' itself again

Nothing makes alot of sense.
When I rode the bike 'before carby rebuild' I went 3/4 blocks up the street and when I would stop to u turn it would have the problem ..... this happened 3 times ?

On Saturday I rode say 30klms , stopped where the first pic was taken, then rode off no problem.
After about 10/15klms more I slowed down, pulled over to turn around and it stalled and had the 'problem'
I kept getting impatient and kept trying to start it and actually went 200 metres around a corner just in the 'idle' mode in 1st gear ..... mainly to stop everyone thinking I had a problem and stopping to help.
But it has to sit for a length of time before it goes back to normal.

When it finally started it went just fine and about 1oklms later I was accelerating hard , got to about 120kmh and she coughed and spluttered to a halt ..... but we know the cause of that ...

Now if the fuel pump is the culprit why doesnt it affect the running while on the throttle? ...... does the pump run all the time while u are cruising along at say ½ or ¾ throttle ? ..... or does it just jump in at 'low' revs ?
