Yes tex, I think it was a combination of things:
o Couple missed shifts when breaking in the bike in from not being positive with the shift lever, its so smooth I was being gentle with the shifter as is normal on a sportbike. My rocket needs a positive kick into 2nd from 1st to ensure it fully seats, not sure if this is normal or an effect of a miss-assembled tranny from the factory, but it's been that way since day 1, so I learned to kick into 2nd positively (not abusively hard, but positive).
o I have had a couple of false neutrals before while shifting, didn't ever think much of it, as every bike I have ever ridden has done it once or twice when ringing them out hard.
o Some hard 1-2 shifts lofting the front end over the course of the bikes life.
o Then add in an inadvertent shift right after the quickshifter was installed from 1st to 2nd at full power around 5500RPM (quite a violent event to say the least).
A week or so later, this situation developed, I suspect the 1-2 with the quickshifter was the straw that broke the camels back, so to speak. I've always felt like 2nd gear has too much drive train lash, it has notably more than any other gear as you go on/off throttle, I assumed it was a side effect of having a shaft drive bike, in reality, it may have been that 2nd gear was ****ed from day 1. Another oddity, when in 2nd gear slowing down to a light or something, as I come up to stop, when I pull in the clutch and the back-torque is removed from the tranny there is a clunk that you can hear and slightly feel, every single time, assumed it was normal as it's always done it.
Now I have a sneaking suspicion that it's been "broken" from new after looking back at it lol.
