The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

The last time I rode was about 3 weeks ago. I finished up by filling the tank and putting the battery tender on it.

This afternoon, I went out to ride. Had an unusually hard time starting it, followed by a huge cloud of white smoke. I turned it off, and a gas/oil mixture came gushing out of the airbox and down the engine. It looks like maybe 1 1/2 gallons has disappeared from my tank, mixed with the oil, and got blown through the pistons into the airbox.

What happened? I put on a rebuilt petcock about 3 months ago. Is it likely the culprit, along with stuck floats? How badly could my engine be screwed? This event took about 15 seconds.
 
Get a new petcock and change your oil. Don't ride it with gas in the oil.

You'll probably be OK. Needle seats or petcock. Did you leave it on pri ? You got an unscheduled engine flush. ;) Change the oil and try some seafoam in the gas to loosen up those needle seats..
 
No permanant damage, just change the oil. Replace the petcock- unless you left it on prime ??? May need to clean/ replace the float needles & O ring on the needle seat
 
I figured out the don't ride it with gas in the oil part. But, what's the likelihood that the engine has been damaged?

And, other than making sure the airbox/filters are cleaned, the oil/filter are changed, and the spark plugs are cleaned, and the petcock is replaced, am I likely "safe enough" to start it up?
 
Left it on prime? Naw, I wouldn't have done something so stupid.....I'd better go check.

I doubt you have damaged engine with short start up. One thing I would do before starting is pull the sparkplugs and spin over engine to be sure cylinder is not filled with gas. Don't be too surprised if you have a "gusher".

Most likely, the repaired petcock needs replaced, not a lot of people have had success rebuilding them.
 
Yeah, this has only happened to about everybody here. Usually only once and you won't do it again!:o

I personally am in the habit of shutting my (new) pingel petcock off 1/4 mi. from home and coasting in.
 
no damage just messy . what you have is temperature related.

every thing may be just fine in normal temperatures. freezing does shrink everything solid.

Make sure to completely remove the plugs and move the leads away from the open hole, you don't need a spark while you are purging the cylinders!:eek:
