Crankcase filled with fuel...help!!

Shell Rotella T is sold @ Walmart, as is heavy duty Delo 400 in a 15w-40.

Don't listen to horror stories regarding oil.

Just avoid anything that says "energy conserving", and you will be fine (synthetic or not).

All oils mix, as they all come form the same place. Even the fancy synthetics (Mobil 1/ Castol Syntec) are simply super-purified base dino oils. You have to spend some real $$$ to get 100% man-made synthetic product. And for daily riders, it's not worth it.

Oil is oil. If in doubt, chage it more often.

I've gotten to the point where I just pour in the cheapest crap around and change it often and consistently.

This has been a great thread for me-- yet another rookie gz250 owner who flooded the engine via the prime setting on the petcock. If the bike just (like 30miles ago) had its carb cleaned and was running great before I dumped all that gas into the engine, could this have plugged a jet again? I've now drained the fuel/oil, swapped air/oil filters, drained the airbox, checked the sparkplug. She's quick to start on the first crank (with full choke of course). Jumps right into a healthy idle, then takes a dump after a few seconds. She'll keep going at a high rev with some throttle, but dies when going back to idle, even when warm and with no change to choke setting. Then she won't start. So I put it on the tender for 24hrs, come back, same thing.

In other threads, idle speed was brought up as an issue for these symptoms, but since she does achieve an ok idle, it's hard to believe that's the problem. New air filter is stock, so doesn't seem to be restricting airflow. Guess I'm hesitant to get the carb cleaned, and doubt I could keep it running long enough to pump through a sufficient quantity of cleaner.

I'm quite impressed with the number of capable troubleshooters here, y'all are awesome. :2tup:

Are you easing back the choke when the bike starts. It make be getting too rich a mixture and overfueling. The GZ usually needs coke to start when cold but will rev up and die due to a rich mixture if the choke is not eased off as the cylinder warms up.

I don't think so. I've never heard of a bike being charged or even questioned about drugs.

I need another coffee. I can't think of a snappy comeback. My imagination got sidetracked with visions of popcorn and a movie. I have a bag of jellybeans too..........oh look something shiny!!!

Yeah definitely. Bike is quick to warm and all. Was perusing another post for a chap who swapped air filters and found some possible solutions. I may be to quick to be ruling out airflow considering the replies there. I'll crank the idle up a bit and see what happens. Thanks for the (humorous) replies!
