Nice to read this thread. My new 2011 G5 has just 150 miles on it - I've only had it just a couple weeks now. I love it so much, and feel much more comfortable and confident riding it since I just passed my 3-day motorcycle safety course and have a real bona-fide motorcycle endorsement now. I've been following the break-in procedure, just riding around town, varying speeds frequently and have not yet taken her over 50 mph. But I've definitely noticed that I get lots of false neutrals. At first I thought it was because I was not shifting properly, but I know that's not the case now - I'm riding it perfectly competently. But like everytime I take her out, I always get at least one false neutral, usually more.
So from this thread I gather just stay the course and it should resolve as the bike gets broken in. If not, of course, thank God for the warranty and I can take it to the dealer for a look over.
