Due to 2 project cars getting in the way of saving for another bike I'm having to sell my leathers before I have ever even used them. I bought them brand new from sportbikeshop about a year ago and have only test fit once or twice. I believe they are a size 44, will double check on the weekend. Was hoping for £750 as they are still brand new, location is Bristol/ Telford and am willing to deliver if needed (if close enough). Open to offers and of course will get photos of my actual leathers when I get home on this weekend Feel free to ask anything

jesussssss christ, luckily mine wasn't quite that bad

Oh okay, i was just wondering if there was anything i was missing. But on my bike the crank breather is just aimed out anywhere and isnt connected on the other end, cheers anyway

Yeah the tank coming has that tap. But if it's still not 100% then i will look further into the carb. Or even get a different second hand one, i can see the adjustment screws have been mangled so everything is most likely way off and god knows what else has been done to it or whatever. In terms of the oil, how does the petrol get to the crankcase? as wouldn't the only way be for it to go past the piston rings?

The fuel only ever leaked when the tank was being taken off. So, from the time the rubber pipes were taken off to it being upside down. During that time all that fuel just want all over me really and not the bike

I will have a read now about this, but my idle is pretty shocking from the start I have read it and some does relate. Only difference is that with mine no matter what it will go back up to 4000rpm, welllll it ranges between 3000-6000rpm. The choke did also work normally before. Also if I look down into the carb when I turn the engine off, it is very very wet and i can see fuel evaporate off it

I will have a read now about this, but my idle is pretty shocking from the start

Yeah I only paid £30 for the tank with a new fuel level sensor (my current one is broken too) and the diaphragm valve moboby thing. So not too bad, especially considering a whole new assembly is £60-70. I plan to replace it and go from there, as the choke moves freely as it always has done and that wasn't touched before the problem occurred. That is why I believe it is the problem and nothing else, but I'll replace it and see. I'll just have to wait till I'm back from uni and what is what.

But if it is operated by vacuum then surely when its not connected no fuel would come out? When I take the tank off, fuel pisses out of the top line of diaphragm with no vacuum

NO . There is a fuel metering device in the carb ( assuming this bike even has a carb and its not fuel injection ) consisting of a float and needle valve . A diaphragm in a fuel tap is operated by a vacuum from the carb intake . If a fuel tap diaphragm is damaged i.e it has a hole in it then it will not operate and you will get NO fuel. I'll tell you what , may i respectfully suggest that you get a Haynes manual called Motorcycle Basics and have a good read on what things are called, what they do and how they work . Once you understand the basic principles of things it will be easier to see what's wrong and put it right. I'm going to look at a parts list for this bike to see if it even has a petrol tap because there isn't one in your picture. There must be reserve function on this bike so it has to have a petrol tap . . Then why would 2 people from the motorcycle garage both have said it? I'm quoting from what they said, which was that one of the pipes go directly towards the cylinder. And if its broken and no fuel should be coming out, why is it pissing out more than ever?

Yeah I know, hence the diaphragm being broken and stuck open, pouring LOADS of fuel in. NO .

There must be reserve function on this bike so it has to have a petrol tap . . And of course i know its not EFI, and it has no reserve tank. As you say the diaphragm is vacuum operated, it if it broken then the fuel will go through the carb and also what was the vacuum pipe, meaning more fuel will go in.

well the tank was empty till the other day, i put in 5L of fresh fuel on monday. there was maybe 150ml left in the tank over christmas and whatever was left in the carb too.

yes the throttle is closing properly, and i know for a fact the diaphragm is broken as all of a sudden petrol pisses out of the tap unlike how a tiny bit would dribble out and that would be all. i assume its dumping loads of fuel but not too much to stop the running of the engine and enough to just have a high idle. It stopped running well all of a sudden after the lines had been put on the wrong pipes. I went to a garage and explained it to them and they agreed it would be the tap diaphragm. I do also know how an engine works btw.

I was thinking possibly, but the then it returns fine and is smooth. The idle was smooth at the start of the day and the throttle hadn't been touched or barely even moved
