Gas in my oil..have i killed it ?

[errorcauser]

Ok, here's the deal. I've replaced the intake boots and o-rings. Dipped the carbs over night, replaced all o-rings in them. Bike runs like a new bike, now. Problem is, I noticed a slight tapping sound when it was running and found that I had gas in my oil. I had no clue that gas was in the oil. So, I drained the oil and put new clean oil back in. Started it back up and all the worrying noise is now gone and it sounds like it should. Sounds really good now.

I suspect the gas got into the oil before I cleaned the carbs, running it with almost full choke to get the thing to run with the old dirty carbs. I don't have to use any choke now. It idles like it should and runs like it should.

I'm keeping a very close eye on the oil level now, but I strongly suspect that the gas in the oil problem started with the dirty carbs. But, with the gas in the oil, and the engine making a tapping noise while the gas was in the crankcase, have I destroyed the motor ? I know it runs and sounds really good now after I put clean oil in it, but will it definitely 100 % kill the motor at a later time ? Will changing the oil like I did save it ? Should I just give up on the thing and forget it ?

Number one cause of gas in the crankcase is a faulty petcock. Make sure there is no gas dripping down the vacuum line.

Your motor is probably fine.

My petcocks good, I've check it several times after I found this problem, and before I found this problem. I sure hope the motors ok, it's worrying me silly.

You'll be fine. GS engines are tough. If you want to be really nice to your engine, change the oil again after a few hundered miles - there is always residual oil left in the engine when you do a change. Also, double check your petcock. Get a clear hose for the vacuum line and make sure fuel is not running backwards down that line and into the engine. Also, make sure the fuel flow stops when there is no vacuum present.

Good luck.

I plan on changing the oil and filter a couple times real soon after this mess. I'm going to run out here in my "motorcycle office" and change that hose out for a clear hose now..just to be safe.

I went out and changed the hose to a clear hose and fired it up, let it run for a while and watched the clear vacuum hose. No fuel coming though that hose.
