Default Tranny Question

Still waiting on winter to vamoose so I can work in my uninsulated shop. 2nd gear pops in and out occasionally and it's either the shift fork or the gears. When changing gears, do you normally replace both the mating gears at once? Seems like you should, but asking any way.......measure twice, cut once so to speak.

It just depends on how far gone the other gear is. Chances are probably good that if the gears are disengaging themselves, then they will both have enough damage to warrant replacing both, but you won’t know for sure until they are in your hands; maybe you caught it early.

No experience here, so theoretically which side would wear 1st, the male or the female gear? It's done it 3 times in approximately 200+ miles, so I don't know if it's a fresh problem....only has 200 miles on it with me riding it and it's a 79 XLS with unknown provenance except the previous owner didn't mess with it at all.

Both to a degree, but I think you will typically find more wear on the pockets/female gear.

Just to note from your first post, you will find that it’s the gear wear causing them to disengage but it’s the shifting components - forks, finger rollers and cam plate - that absorb the force of the gear separation so be sure to look over them closely.

Something else you can check to rule it out is that your shift lever is making its full arc when you toe it up from 1st to 2nd, and not hitting the foot peg support. If the gear shifer is not making a complete shift, it can act the same as and also cause the gear wear.

Incorrect shimming can also cause this.

Going for Andrews gears, I installed forwards on the bike so there's no interference with the foot peg, that might have what created the problem originally, shims and fork width will be checked when it's apart. On another sight a guy changed his gears and found the replacements were 1mm wider, so I'll be checking that also.
