Have an 08250 ninja that we are attempting to start up after a short winter. Put the stabilizer in and ran prior to storing. Bike has power, but just won't start. Already drained the tank and put in fresh fuel to eliminate that. Just looking for suggestions on what to tackle next....

How long did you run it? If you didn't ride for a while, the gas in the bowls may not have gotten full treatment.
Easiest thing to try next would be to drain the float bowls and makes sure the new gas gets in there.
If no-go after that, you may need to pull the carbs and clean the jets.
To confirm it was fuel related before pulling the carbs, you could do your best to get some starting fluid down into the crabs while cranking and see if you get some amount of popping.
Check the plugs also to see if they are wet or dry.

Gummy bears are not gummy bears until they have soaked up a 26 of rum....anyhow....jkv45 said:
Stupid question, is the bowls different that the fuel tank, drained the tank over the weekend and filled with fresh premium, still no love.
never owned a bike and he is the wife's that we are trying to get running.
Did the stabilizer treatment in the fall, as we did the year prior (no issue last spring). Also last spring we did a full service on the bike. Bike is currently sitting around 2700 km.
If it wasn't run enough, the treated gas in the tank won't get into the float bowls. I like to add stabilizer as the riding season ends, then top-off the tank just before storing. There's a good chance the fuel in the bowls didn't get enough stabilizer. Drain the float bowls and get some new fuel in there. I'd add 1oz per gal of fuel system cleaner (Techron Concentrate or Seafoam) to the tank and run at least 3/4 down before filling. Letting the treated fuel sit in the bowls may help open things up (if they are plugged). If not, the carbs need to be removed and the jets cleaned.
Always use Ethanol-free gas if possible. No need to use Premium unless it's the only grade without Ethanol. You'll get the best performance and mileage with the lowest safe (recommended) octane level.

Well, finally ripped the carbs out, cleaned them ( were nit dirty, but suspect clogged), also pulled that stupid factory airbox out and put pods in its place. Bike fired up... As expected, after putting the pods on she is idling at 3000 getting to a max of about 6. Gonna have to get a jet kit and install that in the near future...
The pod filters shouldn't cause it to idle at 3000 to 6000. Either the idle adjustment is way off, the throttle cable is routed/adjusted wrong, or you have a vacuum leak.
I'm not a big fan of pod filters. The airbox is designed to keep the air flow smooth to the intake bells and use the reverse-pressure pulses from one cylinder to help charge the other. With pod filters you lose that. What you end-up with is less torque at lower and middle RPMs with a slight gain at the high end. Fine if you are wide open at the track, but not usually what you want with a 250 on the street.
