petrol in oil wat?

Well as most of u know i bought a yamaha maxim was told its all there,,, but never new the exhaust is tottally shot,,,,going to cost alot to get 1 any way i tried to turn her over, and im getting this great big smell of fuel, ? funny im using a little bowl instead of tank, to check if ok,, ive stripped carbs seem fine, done plugs etc, so i looked into it more, i dropped the oil out, bingo lots of fuel mixed in with oil,, done oil change,, she sniffs,and coughths out of carbs,,,when i try to get her started,and she wont,
1 why did i have fuel in oil
2 can it fire up, without exhausts
any help please

 

fuel in the oil is usually caused by sticking needles on the carbs
if the headers are completely gone, I wouldnt fire it up

 

i aint shaw how long the oil was in there, i hope i can get it all out,or clean it up, ill put a bit of fuel in bores, to clean and fire them up, i got the headers on the bike, but no centre box,or rear pipes,,,,

 

as long as the headers are on, you will be fine.

as for the oil, I would drain, fill and monitor to see if it keeps happening

 

oo just noticed,while u are on, when i blew through the breather pipe on the left of the enjine,it was blocked,and the oil,petrol would come out of the pipe,new oil, clear,cranked her over a bit, shes blocked again,,,,

 

Make sure the petcock is on reserve or run, Do not leave it in the prime position as it will fill the crankcase with fuel.

 

how much oil did you put in?

 

i took out 5 litres? thats with petrol mixed in, i put 3 and a half in, i think, 3 quarters full on the oil sight on the side of enjine,,,

 

They sell an affordable 4 into 1 in Europe for the XJ750 that should be able to be adjusted a little in the muffler hanger to fit your bike.

You can run with just the "straight" pipes, but it'll sound like a dragster.

You did buy a new filter?? The breather is (of course) supposed to breathe, so get some solvent/penetrant in there. If pressure builds in your engine, it's going to push out somewhere.

 

ta mate for that, do u know where i can get an exhaust from, ie name of a place,,,, i aint buying nowt until engine fires up,i took it out and cleaned it up,once i dropped all the oil,then flushed it, and it seems like its blocked again, as i cant breath down it,

 

Well, they call it a Positive Crankcase Vent, so, (not to be rude) did you try sucking on it?? 8O

I don't remember the name of the major catalog vendor in Europe, it was mentioned here recently, can someone HELP OUT with that??

 

sucking and pushing, i dont know alot on these bikes yet, but im learning, like how hard some parts are,bugger
