Hi bud thank you for your reply, I've set them up by eye first of all with thr butterfly sitting slightly behind the third of the three small holes. I've also did my best to balance them at a 2k idle and managed to get them all into 1cm/hg or whatever it is of each other.

Haha bought some to check the fit. Got to be worth a look in my eyes.

Nice, I'll have a hunt whilst I wait for grumpys to reply. Bearingshopuk list the size in a nitrile oring x5 for £1.51.

Just to double check, csmnl list the size as 2.4x39.7mm. Which is correct? If not sure I'll just measure mine of course.

Sweet, just messaged them

Fantastic, what's grumpys?

Also, im guessing its mk1 bandit carb rubbers that will be the replacement ones?

Sounds good to me. You tell me what weekend is best and I'll be there

Thanks so much bud, I'll get them stripped down this weekend but I won't bother you over the festive period. Let me know how much you want to cover it and I'll make sure to square you up.

I'll strip the carbs down again and bring them over to you if the offer is still open?

Although I won't dismiss the possibility of a blockage of course

Definitely worth a try! Any ideas where to get them?

If there is a blockage then at this point I have no idea where it will be. Everything blows through clear and I've also gently run wire through almost all of the passageways too. Granted I may need to go that extra step and sonic clean them. I just can't believe there's anything left to come out of them. Rubbers all seem in good condition and I can't see any splits or tears either.

So after some more fucking about I think it's finally time for me to just suck it up and check valve clearances. I've tried plenty of different approaches and it will not reliably start when cold. Sometimes it will after a lot of cranking, sometimes fuck all until the battery runs dead. It will ALWAYS start with a quick spray and then it will run with a high idle for ages. Once warm I am able to switch it off and on at will, as long as its pretty soon after turning off. If left off for any period of time between maybe 2 hours to overnight it will then not start again. My belief here is that when warm the clearances are tighter and allowing it to start, then once it cools and the clearances open again it then refuses to start. The easy start is bypassing this as it's so flammable it doesn't need the same compression that petrol/air does to ignite.

Okay, so removing the bungs has made absolutely no difference to its inability to start under its own fuel supply.

Just had the bowls off and the drillings seem clear, I've blown them through and pushed some very thin wire through them too.

Okay perfect thank you

That's mega helpful! From the pictures it looks like those have a hole in the bung? The ones in mine are just solid with no hole or anything. Is that correct?

Is it worth a try removing the bungs? Would that even work? In case that drilling between the main and pilot is blocked?

That's awesome! Out of curiosity, what are the small black rubber bungs for that sit in the bottom of the pilot jet hole?

I have boiled all the metal parts in a lemon juice/water mix that was recommended on a lot of other forums and that did remove a lot of crud from them though and on reassembly it finally actually started so that definitely worked to a degree.

No they haven't, I was hoping that maybe they didn't need anything quite like that and it was maybe something a bit more simple that I could maybe try at home first before having to fork out for that on the off chance it works.

Everything has been blown through and I bought a carb cleaning brush set which I have passed through all the passageways to the best of my ability. Float height are set to 13mm currently (manual states 14mm +/-1mm) and the bowls seem to be filling well.

Thanks mate, so I know the jets are as clean as I can get them. And blown through with carb cleaner and pressurised air. I've set the pilot screws to 1.5 turns out as per the manual settings and have also tried them at 1.75 turns too with no change at all. Should I go more than this? I'm under the assumption it's not getting enough fuel as the easystart works.

Hi all! I'm very happy that I've managed to get the bike actually started and able to run to a degree. Now I've borrowed a CarbTune off of a very nice gent and set about balancing my carbs (GSXF600 1994). I have an issue that I can't seem to resolve though. I can get it to start (not reliably though) and then run but I cant get the idle below 2k rpm without it stalling. Each time it stalls it won't restart at all unless I use a very small spray of easy start. Once it starts again it will once again happily run and rev, but only with the high idle. Any tips on where to start?
