Calling all Gen2 owners: 2nd gear issue/s

[b1k3rdude]

Gnasher and I have already chatted at length about this, but I am curious to hear if any other Gen2 owners have have the same issue I am seeing or any other 2nd gear related issues. So here is the history on this -

Riding

• If I change gears gently, roughly a 1/3 of the time it will go into the neutral instead of 2nd
  
• If I make a conscious effort to firmly engage 2nd gear, I can feel the foot lever notch twice (so into neutral and then into second)
  
• If I give it some welly away from the lights, so far I have found it goes into second no problem (I assume because I am being far less gentle with the foot lever).
  

Checks

• Gear lever rubber – This is in good condition, with little to no wear
  
• Gear lever linkage - There is no slack in the gear lever, it is correctly adjusted for my foot/boot.
  
• Clutch lever stack -  It appeared to be correctly adjusted and the span adjustment set for my hand size.
  
• Rear drive chain  - It is correctly adjusted.
  
• Dirt/Old engine oil - The bike has had a recent oil and filter change.
  

Update

• Today I moved the lever down one spline on the the gear change shaft, so that its over adjusted and a little bit too low to deliberately give me more upward movement. I also checked and re-adjusted the clutch lever so it was giving me atleast 3mm on full left/right lock. Then spent a few hours riding around.
  
• What I found was it 'mostly' removed the 'going into neutral instead of second'. It did not remove the 'knotch' that I was getting every few gear changes. But then on the way home doing 20mph behind a car, I snicked from 1st into second and sure enough, went into fucking neutral, and it was going so well.
  

So in addition to my other owners request above, What R1 did the engine for the FZ1 come from? so I can check if owner of that year etc have had issue with 2nd gear etc.
