My bike wouldn't start the other day at 6am on my way to work. (I did
manage to force start it but it cut out) I thought it might be the oil
as I'd given it a proper thrashing on the way home (80 mile journey) a
few days before (hadn't used the bike since) and thought I might have
blown a gasket or something. Being 6am I couldn't see a bloody thing ,
so i put some more oil in. Still wouldn't start, so I left it.
(unfortunately I still went to work )
Today I've taken all of the oil out (far too much in now) started to
think maybe there's water in the oil as so much came out. It was pretty
thin running, I've never changed oil before so don't know what it's
suppossed to be like but the oil coming out wasn't milky so I guess that
ruled out water in the oil.
FINALLY- I undid the air cleaner drain tube and a load of what i thought
was water poured out, so i plugged it back up, then I realised it was
petrol! Now things start to fit together a bit: When I get home from
work I always fill up the bike with petrol and I definately overfilled
the tank last time (I always wondered where the overflow went as it
never seems to drain out of the bottom of the bike, so now I guess it's
pouring into the engine and then in to the air cleaner. I've now taken
out the air filter and it's soaked in petrol...
I just read in the handbook "Never overfill the petrol tank" (whoops!) Can I have done any damage?
Should I replace the air filter or just let it dry out? anything else I
need to do? can i use the oil I've drained as it's not old?
CHEERS for any help.
Overfilling the petrol tank (GSX750F)

**Youll probably find the **
petrol drained into a engine breather or similar in the airbox and into the engine. Thats probably why the engin oil is very watery then again oil that needs changing can get watery. Did the oil stink of petrol. I would change the oil either way.
I may be wrong but i wouldnt think overfilling your petrol tank would cause this problem at all as the extra petrol would just exit through the tank breather and i would think it would be difficult to overfll anyway.
What years the bike. If its carbs its probably the carb float is jammed on or something and the petrol is pouring out of the carbs. Father in law had an er 5 with exactly same problem as you described and this was the problem. His oil was also diluted with petrol.
Change the oil before you run the bike as if it is full of petrol it wont be doing its job of lubricating the engine. I also wouldnt overfill the engine with oil you can cause damage also.
AS for the airfilter if its the paper type it might be worth changing but would sort the problem first.
Petrol in oil
Just went to smell the oil and YES it stinks of petrol!
It's a 2000 (X-reg) so yes it has carbs.
When I took the air filter out you could see a puddle of petrol coming from one particular inlet/outlet.
So now all the excess petrol has drained out of the air cleaner drain tube and I've removed what's left from the airbox I'll fill it up with fresh oil and give it a try (Yes/No?)
No,find out where the fuel is coming from,a faulty needle valve shut off or a faulty fuel tap diaphragm if fitted letting fuel into the carb manifold.
Unfortunately I wouldn't know where to find either of those or what they were if I found them...
Could it not just be the case that now the overflow/excess petrol has been drained off it'll be OK?
No,putting too much fuel in the tank will/should go down the overflow pipe and out under the bike.
You are dealing with a dangerous bike and needs sorting with a pro.
If you mean Ballcocks there fitted to water tanks and have overflows,
Is this yours,

no`s 21 ?
All have overflow pipes.
i think he meant boll ucks
That's a nice response to someone who is telling you the truth and trying to help you,and stopping you from blowing your engine up
Let it be Jaffa90
take it easy mate
sounded like pinhead was expressing his appreciation of the possible severity and exasperation with the bike, not with jaffa's advice, for which I' sure he's grateful. Perhaps the expletive got lost in translation?
Lost in translation?
I apologise if this is the case?
