Default ZX6E 2nd gear problem.

All of a sudden, whenever i tried rolling hard on the throtle in second gear, the bike would jerk pretty bad, it felt like the chain was slipping. Once my rear tire locked up. This happens when i try to wot in second gear, when i do it gently, it doesnt happen.

Strange thing is, when i downshift from 3rd to second, this problem dissapears and it only happens when i switch from 1st to second.

Is the second gear stripped, or is it the sprockets not coming on top of each other completely creating slips?

What do you guys think.

Thanks in advance.

ps. if this is second gear that is stripped, i would do the swap myself. There was a website with detailed pics of step by step process, but i cant find it anymore.

ps2. its a 1996 zx6e with 9700 miles. I got the bike with 5940 miles. It started happening around 9300-9400 miles.

What happens is probably a combination of a couple things. Worn shift forks and rounded engagement dogs. The shift forks get worn and or bent which doesn't engage the gears all the way causing the engagement dogs to round off. That causes them to slip by each other under accelleration. The only sure fix is to pull the engine, split the cases and see what parts are damaged. Probably 1 or more shift forks and at least 2 transmission gears. It's a pain in the butt to fix but it is fixable..

More the gears themselves than the forks. The engagement dogs and slots in the gears get rounded off and then slip out under hard accelleration.

I have a 1993 zx6e and I fixed the second gear problem, but it was not an easy fix. As ZXLNT said, the engine has to be dropped and cases split, and then if the good lord willing, you will be able to identify which parts you need. I ended up needing two forks and two gears. Both of the gears were on the output shaft. It turned out to be a terrible pain to fix but it was a good learning experience. Hopefully you have plenty of patience and good mechanical knowledge before you attempt to fix this yourself. I would like to also say that it was no small feat to get the friggin motor out of the bike. Took me darn near forever. After pushing and pulling and almost breaking my arm I finally got the stupid thing out. I don't even want to talk about putting it back in. Also, if you decide to do this, I found out that there were two different types of gearsets, some had six dogs while others had five, be sure to order the right ones, because I got in too big of a hurry and didn't. Hope I was able to help.

Usually its 2nd and 6th gears I think


13260D and 13260G The dogs get rounded off on one and the slots get wallowed out on the other gear.. and that lets it pop out of gear..

Same difference and same damage and same procedure to fix. The dogs and slots skip by each other under hard accelleration....
