I'm going to echo with the above, check tire pressure, suspension too tight on the rear(check rebound & preload) and rear wheel bearings.
And, if the tire is new, wash out the oily film they bring on them.
The oily film is there, so they don't stick to the mold on fabrication.
Good luck.

 

thanks for the input everyone. I've got to find a better tire gauge, the one I use for the car doesn't have the right angle. Have any of you had any clutch problems? I was wondering if maybe some of what I was feeling could be clutch slipping?

Maybe you have a bad tire, or maybe you're in to low a gear and getting a little happy with the throttle. I can make my bike do the same thing if I'm not smooth on and off the throttle in lower gears. I'm not saying you're doing anything wrong, but these bikes while not power crazy, do have enough to spin out the tire coming out of a slow corner. The engine will brake hard enough to slide the tire if you are in a low gear and chop the throttle.

I always run my tires at 36 front and 42 rear, so 30 would be pretty low for the back.

 

Hello, sorry to hear about the slippery rear tire, however this sounds very similar to a recent problem I have resolved. The reason for my rear tyre slipping was due to the rear shock having no travel and seizing up, I have replaced the broken bit of kit and now the back wheel only spins when it snows or raining or I want it to

 

Hmm ??

 

30 PSI is too low on the street. At least 32 and at that, you're probably wasting your tire to no advantage. The most I'll lower on the street is to 38 and that goes with the tire as much as anything. On the track I only go to 36 rear with Diablo Corsa tires. The lowest effective change I made was when I ran D-207 Dunlops at 32 on the track, at least 36 on the street. I tried them as low as 29 once but gained nothing. I typically run Diablo Corsa's at full boat, 42 on the street with no problem.

An item not mentioned but along the order of the bound rear shock is too much rebound dialed in. That will do what you described. The rebound adjustment on these is pretty bad. The screw turns about 1 1/4 turns if I remember right but it seems all of the effective range is in about 1/3 of one turn if not less. And that third lies in the last 1/2 turn. I know at the track that 1/8 of one turn went from OK to too much. That's pretty sensitive. And it showed up as handling OK but a 20 deg rise in tire temperature, resulting in greasy, within about five hard laps. That was from a typical 165F to 185F.
