where are you located?
i have a R6, i could probably take a look at it for you?

check your tire pressure,
i had a similar problem to what you described,

i was running 31 psi on the rear and it felt like the rear was loosing traction through the first 3 gears when the throttle was wide open and the tires developed tire boogers really easy(sign of low tire pressure on race tires). I rechecked the tire pressure with 3 other guages and they all read 24psi!!! apperently my buddies guage was defective.

i put the pressure back up to 32 psi. and the symptoms dissappear.
