Is it ok to have the trans input shaft bearing on the points side an eighth inch inside the outer case edge? When it is flush, the gear on the outer end of the input shaft rubs the case and shaves the metal. Seems like a lot of lateral play on both shafts anyway; is that normal?
Are you referring to the countershaft bearing? Behind the countershaft sprocket?
The manual I have calls it the needle bearing on the end of trans main axle. The clutch pushrods goes through it.
I'd post a picture, but iPad photo res is to high.

This is the last case I split, it is pretty much right up to the ledge. I don't remember any clearance issues with this going back together. This was an RD, not an R5.
I have posted some Yamaha Tech Bulletins regarding the transmission in the Tech Library that may be helpful. http://www.2strokeworld.net/forum/index.php?topic=51.msg2858#msg2858 (http://www.2strokeworld.net/forum/index.php?topic=51.msg2858#msg2858)
Check out the one called "Yamaha Tech Bulletin - Spacing Transmission Axles and Gears_No 259". Let me know if the link works OK. The file is really big so I'm trying a new hosting method since it can't be posted in a message.

@socal- yes thanks, the link works perfectly.
What I gathered from reading the bulletin is that when the clutch nut gets tightened, the shaft draws to the right, which will keep the gear off of the case.
Thanks, everyone!
