Hi from Oz,
I recently purchased a CB 750 K2, it is a restoration that has been sitting in someone's shed for 10 years. It is a complete bike, once I freed up the engine, cleaned carbs, points & timing added some fuel and the bike fired up. U beauty I thought, until I jumped on it to take it for a ride.
I have no 4th & 5th gear, 1st,2nd & 3rd are all ok. I pulled the gear cover off to inspect shifter fork and selector drum all looks ok. If I go through the gears when I get to 4th i can sometimes hear it trying to mesh but majority of the time it is another neutral, 5th gear there is no noise just neutral. At times it has gone into gear 4th&5th but not very often.The engine is not running when I have been doing this.
I am hoping some one out there may have some idea what is wrong , I will at least have somewhere to start when I pull the motor apart.
Any info will be much appreciated,
Cheers
