Cb 750 1973 I’m having trouble with the second gear on my bike when I shift into second and go hard on the gas it feels like it keeps on coming in and out of gear ,but this is only if I’m going hard on the gas and it only does it on second gear
I’ve changed the clutch already but it made no difference as I thought it might have been slipping


 
Has worn dogs on the gears in the transmission, need to split the cases and replace the gears. Its common in many bikes not just the 750, second gear gets most of the punishment getting jammed from 1st through neutral into second...its the gear that takes the most punishment when people get on it and shift fast. I strongly suggest getting an undercut transmission and swapping it out. Cycle X has complete transmission sets with the cut. The undercut puts a bevel on the dogs so they cant slip out under power.
