same thing happened to me you threw your gears or bent your shifting forks

i crashed realy bad at the IXCR race round 9 (the final showdown)
when i crashed, my foot slipped off the peg and knocked the shifter down into 2nd, which then bent 3 of my shifting forks, it broke teeth off of 1st 2nd and 3rd gear on both shafts. I ended up having to get a new piston, have the cylinder bored, new valves, valve seals, all new gears on both shafts and all new shifting forks.

it costed $1800
it would have costed more but i had corey regan from dreyer yamaha do the repair

The least you could do is TRY and spell correctly. People on here are doing you a favor by answering your questions, the least you could do is make your post understandable.

If your having transmission problems, you need to tear your motor down. That's all there is to it. You can pop the clutch cover off and make sure the shifter, etc is working properly first but most likely you'll need to get into the bottom end, which means splitting the cases.
