I have heard that people run regular car motor oil in their bikes..I can't believe that..Car oil is ok, but its made for car engines that redline at about 6000 RPM's, most bikes don't redline till about 12000 or better..The car oil can't stand that kind of RPM's or Temp's..Am I correct in this assumption? Also What benifit would I get from running a synthetic oil and not a regular motorcycle oil?
Car motor oils labeled (Energy Conserving) contain anti-friction additives which, will cause clutch slippage. I went to a semi-synthetic oil on the R1 at 3000 miles. I plan on doing the same thing on the Busa.
Car oil will work fine, I like castrol gtx, also they dont make oils based on rpm ratings I dont know where you people get this poop. And it will never hurt your clutches syn or non synthetic. 9.40s not bad for an oil that is ruining my motor and clutches. LOL

How many miles has your bike done?
Synthetic is the way to go. Most of the other companies buy the polymers for there oil from Mobil so if you pay big bucks for motorcycle specific oil don't waste you money. In a motorcycle engine it is the transmission gears which put the viscosity of you oil to the test since automotive engines use separate transmissions the oil only lubricates the engine internal moving parts. Motorcycles have to also lube the transmission with the same oil the gear pressures are what break down the oil viscosity Mobil 1 synthetic 15w-50 will stand up to this kind of abuse with no problem and you will have no clutch slippage using this oil. It's all I use and have never had and oil related failure even in my dragbike...........
