Crashed, Have you received all the factory updates? The twitchy front end issue was addressed by the factory already,I thought. Make sure that you are getting the most current info from your dealer, and double check EVERYTHING.Call another dealer for the price on the oil filter. I thought the new ball joints cured the front end problem.. Again, This is the time to check on the updates, Dont wait. Congrats on getting a super quad... As far as the top end speed, for 25.00 R&S performance will remap your efi (probably back to what the FX was) for greater performance...Sounds like a good deal to me. Let us know how it goes...
