So, my bike started leaking pretty bad during practice and my buddy said it could be the shifter seal. I saw some videos of people just popping theres out with a scribe or flathead screwdriver, so I tried. 

 

And then I royally screwed it up. Bad. 

 

This seal does not want to move at all. I chewed everything up pretty nasty trying to pry it out and it's not working. 

 

Any other ways other than the scribe/screwdriver trick?

 

Here's a pic to churn your stomachs. Oh yeah and my race series starts this next weekend so im screwed. !!!! I'm going to see what the shop can do tomorrow.

No big just replace the seal.  If you can not get it out you may have to pull the shaft out the opposite side of the engine.  Haven't done one in a while but it is not a big deal.  You have to pull the right side cover off to get to it.  Shouldn't take more than an hour tops.  Just follow the service manual.

You could try putting two screws into the seal (close together) and then pulling on them with pliers.  Or try a hooked pick - http://www.harborfre...e-set-1816.html

Drain the oil, drain the coolant, remove the right side crankcase cover, remove the shift shaft.  The seal will pop right out and you won't gouge up the shaft in the process.

Does that require the removal of the clutch basket too?

 

I finally got it out this morning after picking at it with my pick a little more. I really had to apply a lot of force to get it to move. You can see I gouged my housing a bit from when it slipped a few times but the new seal is in and appears to be working. I won't know for sure until i go ride it hard at the track again. You can see how bad the seal was getting tore up from the pick trying to remove it.

Not strictly, but it makes things a little simpler.

Man it looks like you may have gouged it pretty good there. For peace of mind you might wanna try to clean the sealing surface with some emory cloth and maybe put some yamabond or something similar on there to make sure it really seals well. In my experience seals and things like that will almost always start leaking again if the surface they are sealing against isnt very smooth.
