yamaha g9 quits after a while

thanks for the input guys
and new guy i did take a part the carb and cleaned it up and that didn't do anything...

hey new update here, i drove it for a while today and the next day there was engine oil blowen back from my valve cover into my airbox!! (From the tube that leads to the valve cover from the airbox)
so i changed the oil and put in the right amount of freash stuff, but still acts up...

hey small block, i did see if there was spark when it acts up and their is plenty of spark coming from my new plug.

Does the oil smell like it has gas in it? Or did it when it was blowing into the air box.

sabercat · 10-09-2008, 02:10 PM

no it was just dirty engine oil, thats why i changed it

sabercat · 10-09-2008, 02:12 PM

do you guys think it could be the diafram or whatever is suppling air to the fuel pump, cuz my pump and fuel filter are brand new so it can't be that...

i'm 15 and don't have to bring it to a $75 an hour macanic, so i'm trying to fix it myself

I really think the problem your having is going to end up being something simple like:

air leak: air box not sealed completely, cracked plastic spacer between carb. and intake, fuel problem: fuel filter (located in the bottom of the tank on these models) if you have an in line filter on one of the fuel lines you'll have another one on the bottom of the fuel tank
fuel pump: clogged or full of grim
float on carb.: trash causing too much fuel to flow into carb.

Get us a pic of your carb. and air box if you can. Maybe another one of your fuel pump and lines.

Make sure, only 1 quart of oil in the engine. Some of the dipsticks were mis-marked. When it dies pull the fuel line off at the carb, crank it over and see if it's pumping gas.
