If you have gas in your oil, you either have piston rings that are leaking through or valves that are leaking.

    I can't help you with that, it all depends on the mechanic. There will be at least 4 hours labor involved though.

Gas getting into the oil

Usually this is caused by a leaking float valve in the carburetor. It seeps into the engine (when not running), past the piston rings, into the oil. Also you should check the float level.

Gas in my oil , 1982 1100 gl goldwing aspencade. what can I do

sure its oil? It might be filthy gas or something. If theres a strong smell of gas it can mean many things. some being costly, some being simple. if you left the gas valve on, you probably flooded the engine. youll have to let the fuel evaporate, or turn it over with the killswitch on to pump out the excess fuel. you might have to change some spark plugs if you did this. If its something else, it could be carbeurator problems or problems with the rings. If its really oil leaking out, then somethings wrong.

Strong smell of gasoline after riding my 2004 fatboy

Are you turning the gas off at tank ? If not I would do that first, then if that wasn't it then I would check your air box and see if gas is running out your carb, if so the float/needle is not sealing off, and also check your gas cap for proper venting

My 2011 streetbob got knocked over onto the right side with the lights on for about 30 minutes and all the gas ran out. now it just clicks when I try to start it. I put gas in it but want to make sure...

I doubt you have any fuel in the engine as the bike fell on the right side. Even if it ran out of the carburetor, it would have been flowing away from the engine since it fell on the right side. If you think you may have some fuel in the cylinders, take the spark plugs out and spin the engine over a few times with the starter. Just a few turns should tell the story. If you have fuel in the crankcase, there's no easy way to get it out other than run the engine and pump it out. This may contaminate your oil. Start the engine up and run it for about a minute or so then smell of the oil by pulling the dip stick out and taking a sniff. If it smells strongly of gasoline, change the oil and filter. Otherwise, you should be OK in that respect. Now, I don't anything about the security system on your bike and it may have some systems disabled.

Good Luck

What fuel and (oil does) 2003 sportster a XL1200C take?

You need engine oil, usually 20 W 50, and primary case oil, 50 weight.
Depends on your Climate. Cold, you can use thinner oil.
You can buy from a Harley Dealer, Genuine brand Harley Davidson Oil.

I have 1991 honda cbr1000f. I note that the oil smell like gas, so i change it. but after i change i still smell gas. I wonder what happen to the piston ring or the cylinder worn.. thanks

It is not unusual for the crankcase oil to smell like gasoline. What you should take note of is if the crankcase oil level increases by any noticeable amount. This would be caused by the carburetors overflowing and allowing gasoline to run through open intake valves, into the cylinders and then past the rings. Still, this is a very unlikely scenario given the fact that your bike has a vaccuum actuated petcock.

The botttom line is this; don't worry. Small amounts of gasoline that may present in the crankcase oil is going to quickly evaporate once the engine is up to operating temperature.

Only runs half throttle

so, can you tell me what kind of carb was on the bike before? was it factory? and what kind of carb was just installed? blue smoke can be caused by burning transmission oil or a rich fuel mixture. that might be a bad crank seal or case gasket, or just improper fuel/oil ratio or improper jetting. black smoke on the other hand is usually caused by too much gasoline burning, but if there were enough gas entering the engine to cause black smoke, the bike probably wouldnt run at all. but, if you can give me more info on the carb swap, and if possible any jetting information or jetting changes, thenI can definitely tell you what your problem is.

Engine skips, won't go over 55 mph. Works fine below that.

Hi ..... Go through the above list, pay particular attention to fuel delivery ie blocked breather in tank, any filter fitted to tap or change in line filter if fitted. Easy to check, take off fuel delivery to carb (place container to catch fuel), start bike and fuel should come out a strong contant flow.
Let us know how you get on.
