2003 R6 -

2nd gear has been popping out!

And now the bike does not want to down shift?

Anyone know what is causing this, (please only respond if you know, let's not fill this thread with speculations).

Also would like to know what year engine can fit on this year bike?

PS if you are in the NYC area & know someone selling an engine from a totaled bike, send me a message.

peace!

Sounds like your shift forks are bent or worn and the gear dogs on your drive and driven second gear pieces are shot. Basically you need to pull the motor and split the cases. Probably cheaper to replace the motor.

its hard not to speculate with so much information provided. Check the detent spring first. The dogs were fixed that year so it shouldn't wear out. If you do want to replace the motor, an 03 or 04 are the only years that will fit. Oh, and the 06+ S model.

Thanks to you I opened up the cover, the spring looks fine, but I discovered a small piece of the shift shaft broken, hopefully this is what the problem is. Below are photos.

So to clear up what I was saying in the PM's, when you put it back together, it doesn't really matter where the star gear is positioned, but it does matter how you put the shifter back in. In photo two, on the backside of the shifter to the right of your fingers, there are those two little claw thingies with springs on them. When you this back together, you have to make sure that you have 2 pins from the star gear being gripped by those claw thingies. Otherwise it isn't going to shift correctly.
