more false netural questions

[rmstrg]

im am having the false neutral problems like many others on my 2010 rmz. i was wondering if there is anyone that has an actual fix for this problem? i have read the gears are different in the 2011 bikes but they seem to be having the same problem. i have also read about "coatings" on the gears but dont know if this is an actual fix and is expensive. id rather put a thousand dollars in reliablity than a dr. bill or exhaust. any answers will be greatly appericated!

i just read something about a 450 shift drum and spring. what is the difference and does it fix the problem im having?
