POPS INTO LOWER GEAR

[chief]

It may simply have not been in gear completely... rule of thumb... happens once forget it... happens twice monitor it... happens three times - needs fixing.<LOL>

Hello,
I am new to Drifting, with a 2005 800 model.  Only 5K miles on it, but it did something strange yesterday on the freeway.  It popped from 5th down to 4th gear without any help from me.  My foot was not touching the shifter, front or rear.  Is this a warning of worse things to come?  Anyone else experience this?
Thanks,
Greg
