Help, crankcase filling with fuel

[Pipeliner_86]

Just picked up a 1981 GS1000G, and I am having issues with it.
It runs smooth and crisp throttle response, but it has serious problems. I took it for my first ride down the road and all was fine until I started putting the fuel to it. It started to run strong, then began falling on its face and then spewed oil and gas from the airbox. I ended up pushing the bike home and got it into the garage. I pulled the airbox and the rubber boots from the carb to the box were melted, and there was also oil/gas running out of an overflow orfice on the bottom of the case above the exhaust pipes. The oil sight glass was full, so I pulled the oil drain plug and the oil poured out with a heavy mixture of gas in the oil. The case was really full too. It filled my oil catch container I use for car oil changes.

I hope all my bearings aren't wiped out from all that gas in the case. Has anyone had this happen to them? Any help is appreciated.

Thanks

Pretty much anyone who hops on a thirty year old motorcycle and rides it without doing any maintenance has. These are super reliable bikes, but thirty years of neglect needs to be made up for. Cliff's list will show you the way.

Your problem is typical of carburetors that need to be cleaned, and maybe a petcock that needs to be replaced. You probably didn't hurt the engine at all, it has roller bearings and a small oil problem for a short time won't hurt it.

Nice Intro
Wait for the basscliff want to be jesus inundation and then.

View this from a reasonable POV.

Frain you oil Then check your petcock and associated tubing.

Not all suzuki bikes have roller bearing you ignorant guy you!

Jeep, you are absolutely correct, but he did not say "all Suzukis have roller bearings", he said that the original poster's bike had roller bearings.

Please keep your comments relevant to the thread. And calling one of our better members "ignorant" does nothing to enhance your credibility.

Hi Mr. Pipeliner_86,

Yours is a story that has been repeated in these hallowed annuls countless times. New owners of vintage motorcycle machinery all experience many, very similar, seemingly mystical conundrums trying to enjoy their newfound mechanical Pegasus. At first they will dance, they will chant, toss beads, smoke pipes, and curse. After these efforts have failed they will resign themselves to actual, proven, repair procedures that have been performed on these classic steeds for decades. I am here to point you down the path of enlightenment. When you can take the valve shim from my hand, you will then be free to ride your Suzuki GS. Now, gather up thy tools, gird thy loins, and steel thyself for copious amounts of GS knowledge.

Anyway, let me dump a TON if information on you and share some GS lovin'.

Wow Cliff, how long did it take you to come up with that one? That's pretty good.
