come on now.. don't be pulling my local homie's leg.. LOL
pretty sure i saw your post on TSB too. As many indicated, it will happen or it won't. Keep good oil in there, (rotella blue jug or silkolene pro4 synthetic) and take care to make good shifts.
IF you ever have a problem, hit my mechanic and fuel injector business partner, Jim Scala up in New Port Richey. He could do an r6 motor with his eyes closed at this point he has done so many for me over the last 9 years..
very reasonable prices, not dealer rates. give me a call if you ever have questions.
As some mentioned, you could get a used trans if needed, but if you had the bike apart "IF" (lets not jinx it) the 2nd gear goes.. i would just buy a new 2nd gear and shift fork as that is likely the only gear to show damage. That happened on my 2000F4 honda my AM racing season, but i was downshifting some gears without a clutch (i don't do that anymore..LOL)
Some drag racers, and some model roadrace bikes get the gears undercut at Falicon in Clearwater, FL, but that is big money and simply not needed on an r6.
