Can any one in the UK help me with some gears, I have got a full spare set of gears unfortunately they must be for a later model.
As I have allready mentioned my cb750 jumps out of 2nnd gear while under load and on inspection of the gears they look OK but after the advice I have had on here I would like to replace 2nd gear pinnions
The part no's are 23431-300-010 2nd and 3rd for main shaft 24teeth and 27teeth
and 23440-300-010 2nd gear counter shaft 41 teeth

Unfortunately new parts are prohibtively expensive another mortgage
Cheers
