Need to replace the transmission on my bike I thought it was an crf450r 2008 but the engine has me thinking the previous owner swapped out the tranny for 2007 parts. When I came across the three stud dogs on some of the gears when I opened it up it threw me way off. Heres some pics to show you better.
Thanks all, I have tried to search the net extensively but can't seem to find the info I need
Pay no attention to the markings on the whiteboard under the gears it's all out whack now....

I want to find a good condition replacement for the complete transmission. this ones a bit stuffed and i dont know what compatible trannys or years will work with my bike. sometimes like 05 through to 08 will just fit right in I have no idea though...

That's a link to the gallery of images. Thanks again for any advice.

ALSO the number or serial im not sure which is which is PE05E 2610097
