I have a new 06 and am still in the break in process (300 miles). I have had numerous miss shifts from 5th to 6th. None of these were during any type of aggressive riding. When it happens, I am expecting to be somewhere around 4K, release the clutch and the tach flies up to about 9K. It's just like a 1st to 2nd neutral shift. If I let off the gas, sometimes it will drop in without doing anything else. Other times, I have to actually pull in the clutch and go for 6th again. You can actually hear the gears skipping when it happens. Like I said, it is brand new and obviously under factory warranty so cost is not an issue. I am just curious as to whether this is known issue with the Busa. One of the things I have loved about Suzuki is their silky smooth gearboxes. So this is very unusual to me. Advice?
