Actually, in the "intent to recall" notice that was posted in another thread, it says exactly that, owners should not ride their sleds.
The problem I have with riding it and depending on the warranty is this: I have a 3 year warranty, one year is gone due to a crappy winter (not yami's fault of course). They KNOW they have a problem, I want it fixed now because if i wait for it blow up, it could be a situation where I don't get the sled back for 3-4 weeks, essentially sh!t-canning half of my season and 2nd year of warranty. Yamaha needs to do what's right..now!
