High temps, low grip?

That certainly would affect the handling of the bike. When you adjust your speed prior to entering the corner, the weight is going to transfer over the front tire, load up the front suspension and compress the forks, and the rear end will lighten up and unload the rear shock. When you trail off the brakes and begin to apply the throttle at apex and beyond, you'll get that weight transfer back onto the rear and load up the rear suspension and unload the front.

Okay, so perhaps everything was perfect but you set the rear preload too soft, now what will happen is as you add throttle you may feel like the rear end wants to step out on you, so you close the throttle, but now the bike feels like it wants to fall into the inside of the corner, so now you get back on the throttle to stabilize the bike.... Blah blah blah.

Soooooooo... Add a ton more preload and study up on Suspension Sag on youtube and with a search in the rider forum here.

If you want to corner like you're on rails, typically you'd want a stiffer, less forgiving suspension so that throttle and brake inputs upset the balance of the bike. One of the biggest things most riders will do is upgrade their suspension or even get it adjusted properly by a tuner for their weight and riding style by a tuner such as Pro6 Cycle or Riders Choice.

If you are smooth with your inputs, clutch, throttle and counter-steering, you may find that your rear end will "wallow" mid corner. Ride through it, but be aware that your rear shock isn't adjusted properly.

But, more preload for better cornering can make for a nasty ride on pot hole filled streets, and imperfections mid corner, like tar seams, pot holes etc are MORE likely to upset your cornering lines, possibly even causing the rear tire to break free and cause a highside.

Practice: Increase the preload and ride a couple of familiar and predictable corners, now back it off step by step until you find a setting that you like that's comfortable. Try not to change too many factors all at once, like damping, rebound, preload, tire pressure so that you can concentrate on once adjustment at a time.

Now to think of it, during the winter I put on A LOT of weight due to an injury. I weighed 145 before and now am a little over 160. The spring preload is still set at the softest setting! Is this enough to cause the problems I'm having?

The tires are the original irc tires that came with the bike. Even though I've heard nothing but bad things about them, surely they and also I can't be that bad..., right? :)
I'm on bt45s now and to be honest, I liked my IRCs better. But I'm sure that'll change over more time as I get more experience with these tires. I got to know the IRC tires really well (and how my bike handled with them). It should make a noticeable difference if you bump the preload up to the next level that matches your weight - check the manual!

Unfortunately, the rear springs on our bikes aren't too great. There isn't much room for adjustment. If you wanted to get it tuned, then you'd be better off replacing it with an aftermarket shock (which I'm planning to do next year).
 
Was riding around today but for some reason I just didn't feel confident leaning the bike over. It constantly felt like the bike was going to drop out from under me with any real lean angle. I went home to check things out and can't see anything wrong with the bike.
So I'm now wondering, is it the +30 degree temperatures we had today making the road feel "greasy", or is it just in my head?
Problem is you are riding a ninja 250. Tires are crap, hot weather should be better for the tires ...anyways

No Offense but all this talk about limits and leaning angles, you need to learn how to ride your bike.

Don't worry about tires or suspension or any of that stuff until you get some proper instruction

Good luck
