lets see if you can help me,im stumped! i recently split my case open to fix my tranny. the problem that when i was in 2nd gear it would like clunck and pull really eraticlly when i was on the throttle like the gears were shock loaded and some teeth were mabey missing. 1st,3rd,4th,5th,6th all work just fine!! anyway theres nothing that really is bad looking once i got it apart, yeah some bearings are a little worn but nothing is broke, im frickin stumped!! Thanks

shift forks bent at all causing the gear to be pushed too far??

yes check your forks,but also pay special attention to the gears.not so much the outside teeth,but there will be 3-4 cogs on the insides of the gears.these engage to the gear next to it.the cogs are supposed to drop in holes of the neighboring gear.sometimes the cogs get rounded off and will slip out of the gear that they engage with.you will see evidence of the cogs and holes on the mating gear wearing away.this is usually cuased by shifting without the clutch.if you see this wearing of the gears,replace all of the affected gears.not just one.and you will have to replace the shift forks and shift fork rod.usually the edges of the forks will be ground up.this is from shifting with out a clutch.always use the clutch to shift it.

Here's another option for you if you find nothing wrong with your tranny gears and cogs.Inspect your chain and sprockets,The chain may be trying to climb up your sprocket,Same symptom as your describing,I had this happen to me and mine would only do it in first and second gear on the throttle.
