does slipping out of 2nd gear on weak shifting makes matter worse?

[mtc]

if i kick it in no problems

if i half heartedly shift it in on occasion it pops back into neutral,

since i ddin't grind the gears going it will it damage anything coming out like that once in a while?

Its not the grinding of the gears, when the gear is not fully engaged under load, it jumps out while the shift fork is trying to hold it in (like a BANG). This bends the older style shift forks. Once bent enough, it will not hold the gear in place under load. The test for this is simple. Once in the gear you suspect is faulty (2nd gear on my 86), take it gradually up to redline (somewhere safe). Depending on how bent the fork is (or not) the symptom will be a revlimiter like surge. That is the gear popping out under load, then once out, the load is lighter and it goes back in, then out again real fast like.

you mean like engage and not engaged so on and so forth

so if, it's bad then doing that makes it worse?

funny thing is when i rode it home 150 miles, no issues and the po said someone fixed it....yeah right

so does the fact that a light shift not fully engaging the second gear indicative in and of itself a second gear  problem?  without going the 2nd  gear all the way to redline test
will test this weekend

Yes and Yes. I think the aggravating issue is that Neutral is between 1st and 2nd gear when shifting. When shifting during higher revs and missing second (less than positive engagement) means all that energy gets applied to parts not designed for it. I am sure you can bend even the newer shift forks this way.

lots of bikes have this issue, i wonder if the Japanese zero had flaws  lol

Worst thing doing to a gearbox is shifting carefully that is how the dogs it gets damaged.

i did it to 6 grand , no popping out, then i ran out of room, it missed 3rd and it didn't go in to 3rd today.... but if i pay attention on the shifting the bike "does not have a 2nd gear issue" thanks again
