the saga continues

[Gypsy]

ok peeps heres the lowdown
on kawasaki GT750... 2 coil system 1+4 and 2+3
at R&B
no 3 not firing.. carb flooding .. fuel leaking into air filter...plug on 3 black as midnight...
changed coil for 2+3 and new set of plugs all round..
ran great all the way home 200+ miles
next morning ,,, 20 miles later flooding again on No4, checked all leads cleaned out air filter... ran fine

4 days later ran fine for 50+ miles had a cupper and the bitch was at it again not firing on No4 agggghh swopped coils over from 1+4 to 2+3 , fired up great no problem another 200+ miles no problem

next day went 90 miles no problem... same again the day after no problem ....

this morning " goddammutherfuckingsonofabitch" fuel all over B&Q car park.

No4 playing up again....
No 1 off same coil is running ok ... so swopped leads off 1 to 4 to prove not electrical... NO 4 still a bag o ****e.

have checked float bowl and fuel is getting there ok


ant ideas as to whats going on before i do the hammer test ????? :D :D :D

[dracken1]

by what you've said its a carb flooding prob not electrical.

do you have an inline filter.
if not fit one, clean and blow out the carbs.

check there is not a step in the float needle tips
it only needs a small speck on the tip of the needle to empty your fuel tank

[Gypsy]

yeah thats the trouble ... No4 just keeps flooding

nope no inline filter fitted

is the carb spray cleaner any good????

[dracken1]

carb cleaner won't clear the fuel lines of specks of dirt or rust

run some fuel on to a white sheet of kitchen roll to see if you have a real bad prob

[Gypsy]

ok cheers :D

Hello.

It sounds like you could do with gettin a new set of float needles. I think m and p do pattern ones now that are just as good but a good bit less then the oe componants.

Best of luck

we been pretty lucky, before we got it the bike was not used for 3 years before hand... managed 3000 miles before anything really started going wrong lol

[Gypsy]

ok im a bit of i novice at this ,,, will any adjustments have to be made if i get a new set of needles... ie balancing ????

[dracken1]

if the carbs are already in balance new float needles won't alter them.
but as you may end up fitting pattern needles check the float hieght is correct as they may be a different length

Having worked on this trike on the side of the A303 - twice - I can say that firstly the HT leads were too short to the coils and were being pulled out and chaiffed. They need to be longer.

The fuel issue - black plugs, petrol everywhere is a float problem.
We did tap the float bowls with the wooden handle end of a 2lb lump hammer in the course of our investigation at that time.

The float needles (not to be confused with mixture needles) sound like they are sticking or jamming open with particles carried from the tank with the fuel.

First off, get an in-line filter and fit between tank and carbs, and then strip the float bowls off and clean the needles and their seats.

If this doesn't work then you may need new needles as mentioned.

[Gypsy]

tis looking that way mad cos the coil that had the short leads has been replaced... all nice new shiny ones on there now :D

[Gypsy]

also found i ickle flake of red stuff on paper when i drained the 4th float bowl.... ya think this could be the problem????

inline filter being purchased today :D

[odie]

I used to run a bike breakers years ago.
The first thing we used to do if the bike had been stood for any length of time was to clean ther carbs out!
Any fuel left in the carbs would turn to some-thing akin to varnish.
If the bike had come from ther states it was worse cos the yanks have crap fuel.
ALWAYS check the the needle valves (under the floats) cos this is the most likely where the problem lies if your carbs are floading!

All this reminds me of the saga of Mrs R's ZL*, which at this time last year had exactly the same problem - which lead to us heading to the Pissed Indian, two up on mine, with loads of luggage, tent, sleeping bags tied to' saddlebags etc (which almost fell off on't M25) and me waddling round the roundabout off the M20 as we almost went off on the wrong exit :eek: - Something about crap in't tank.

How about Petsealing the inside of the tank. Would that help

*I wonder how that saga's going, eh Mr Chaz? :)

[Dougie]

Definitely fit an in line filter.By the sounds of it the float level is probably wrong on the flooding carb.Even out by a couple mils can lead to problems.Make sure all four levels are correct and identical.If it stilli happens then it probably is crap in the fuel hence the filter.My GS550 has done over 100000 miles on the original carbs and the internals are still in good nick.

[Gypsy]

inline fuel filter fitted, cleaned carbs out..and ye olde trike is up and running again so hopefully the problem was the bit of crap that was in the float bowl

*** BIG 'KIN GRINS***

cheers peeps,
im on a very steep learning curve with all this stuff and all your help was great :D :D :D

[Dougie]

Cool! :D :cool:

Glad to haer it!!

The red flake you mentioned earlier sounds to me like paint that has maybe chipped off at the filler cap. Is (or was) your tank painted red?

If the paint is flaky or there's a problem with stuff floating around inside your tank then Petseal should cure it. I had a similar problem once with a 250 Superdream and spent long hours stripping carbs, adjusting float heights etc. etc. After I sussed the flaky paint at the filler cap and Petsealed the tank the problem was resolved for good.

Good luck

the undercoat was red :D

petseal it is then lmao :D

[Mitch]

petseal it is then lmao :D

Have fun trying to find a tin, a lot of the car spares shops go 'petseal, what's that, is it for sealing up pets?'... :eek:

Seriously, I only know of one bike shop in sussex that sells it, tho I could be totally wrong - try looking in Classic Motorcycle Mechanics for their address.

Tho' if you find a tin, let me know will you? I need another tin for my 'new' Spectre Tank that I'm painting up (I mean that in the loosest possible terms with my fillering!!) it's got all sorts of crap in it!
