Is the tank fuel cap ok Ie no restrictions? you have to have a good airflow as well,try it with the cap removed,also see if you can fill a litre bottle with fuel from the hose. Caltex 98 doesnt have Ethanol,should be good,as rocket said it is definatley a fuel supply problem, is the filter in the tank Ok? just guessing now,did you try carby cleaner?

I think we have covered everything, A carby is a pretty basic item, all I can suggest is to recheck the fuel supply from the carby inlet to the needle and seat,making sure all of the passages are clear,maybe use a small piece of flexible nylon down the passage. Other than that,you may have to bite the bullet and let a mechanic have a look at it.

Hope it goes well for you

BTW here is a exploded view it may help diagnose any problems

well i am a car mechanic by trade so i have a pritty good idea on how they work but this one has got me bugged :unsure:

i have looked over that parts Diagram a million times but it is all there :dry:

the next thing i am going to look at is the floats they mey be the wrong ones for the carby :unsure:

thanks for your help Ollie

[DeanMember]

No worries mate

Ollie

[dougMember]

Mick any chance you could post some pix of your floats just wont see if my ones are the same cheers if you can

[Mick DMember]

I dont reckon they would be the wrong floats.That is certainly drawing a long bow. :blink: Is the carby old and well worn? Have we explored float level? Even cable adjustment?

[GregMember]

Can you source a carby for loan that you can fit, even a standard one that would tell you if its carby or fuel supply, and I dont have one anymore, Chicken may have I will see what I can find out for you

TB

[dougMember]

i have the standard one that i pulled off the bike to put the mikuni on the standard one was ok no probs with fuel supply with it on

how would cable adjustment help the cable is new anyway

the carby dose not look worn dont know how old it is as it was second hand

[dougMember]

ok so i found out that the floats were put in wrong maybe by me :whistle: so that have fixed the fuel flow problem

now i have another problem and that is that there is fuel poring out the hose on the bottom of the carby only stops when you turn the fuel off is that to do with float level :unsure:

[alanMember]

sounds like you have a lot of patiance think your on the right track but
