Have 2005 CBR 1000.
Under heavy acceleration in 2nd gear, occasionally it will pop back into neutral. Once I back the throttle off, it will re-engage 2nd without me having to do anything.
Not a regularly thing but happens occasionally. It doesnít happen as soon as 2nd is engaged. The gear can be selected and revs increased to near redline and then it will happen or as low as 6000rpm.
Only happens on the up shift.
Have dropped it back from third and then accelerated, on those occasions it holds fine.
Donít believe its rider error.
Any suggestions. Have already adjusted linkages and no fix to problem there (so far)
