Hi all I have a 1999 4TX and Im having real trouble trying to get it to run. Ive cleaned the carbs and put new float needles in and new o rings in the housing where the needles sit. It seems to be starved of fuel (I think) however the plugs were wet when I checked and also there is fuel on the valves themselves. float heights Are set to 11mm however Im not 100% sure this is accurate as I have measured this with a steel ruler and not the fuel and tube way. Any ideas on what to try next other than be 100% sure about float heights. Ive also made sure Im definitely getting a spark which I am doing, fuel pump is working fine also
Cheers

Are you using any choke ?  Also, are you twisting the throttle when trying to start it ?  Should really only need choke and no movement of the throttle until it's fired up.

I’ve tried it with both choke on and off and also with throttle open and closed and still
No joy. Unless there’s something seriously wrong with the bike mechanically I’m convinced it’s the carb set up

Was it running ok before you worked on the carbs ?

As an update, Im back to square one now with the bike. I have it running however as soon as I put the air box back on it just dies like it is struggling to breathe properly but then when the air box is taken off again it kicks into life.
Also, whilst running it yesterday for around 5-10mins in the garage the header pipes were bright red with heat, I think it is because the bike was stationery and also the the radiator was dropped off whilst accessing the spark plug so it wasnt cooling the bike when the fan kicked in- do you think these are the reasons or could it be something more serious?
Just to add, I notified that the air box days on it 3vd however my bike is a 4TX. I cant see it being an issue but could it be possibky?

Ok, so assuming the airbox is clean and having removed the air filter previously with no change, you must be disturbing something when fitting the airbox.  It's pretty cramped around the airbox and easy to disturb wiring etc when fitting the airbox.

 

iirc the mk2 uses the 3VD airbox but with different inlet rubbers for the mk2a.

 

The only other thing I can think of is it's running really lean.  You could try pulling on the choke to see if it runs better with the airbox on.

Are any hoses going on the right way? Have you tried without the airfilter? Assume airfilter is clean?

Yeah hoses are all ok and tried with and without the air filter in. I think Im going buy new rubbers for the carbs and just see. Im convinced its an air leak somewhere

Running hot is most often running to lean.

How does the spark plugs look ?

How did you clean the carbs ?

Have you changed your fuel filter?

Did you drain a pint or two from your tank before reinstalling?

 

Carbs really dislike E85 fuel, what we find on pumps these days. I drain the condensation from my tank every 2 months and use a fuel stabiliser now and then, as E85 does not separate from water as good as proper fuel.

Yes tried feathering the throttle and still no luck as it fairly quickly returns to being awful and not running. I have to say however that if I keep the Revs fairly high (around 5000rpm plus) it runs ten times better. Ive also tried with the idle screw.
I havent changed the fuel filter so that is something I could try and in terms of what fuel it is Im not 100% but it could well be the E85 you mesntion. Do you really think the fuel can be playing a big part in causing this issue?
As an update, I have since booked to take it into a garage next weekend but I can solve the issue myself in the meantime then great!

Also regarding how I cleaned the carbs. The jets have been blown through with a compressor and they have also been in an ultrasonic cleaner. New float needles also installed and new rubber O rings in the housing of where the needles sit.
