The transmission was whining in 1st,2nd & 3rd and made some LIGHT noise just barely audible over the engine/exhaust @ idle. It was silent in 4th & 5th gear. Given the way it sounded I was pretty sure it was the input shaft roller/needle bearings that go inbetween the input shaft & output shaft - as they were the only bearings I didn't replace when I rebuilt the trans about 2 years ago.
This last sunday I had Rob come over to give me a 2nd set of hands to yank the transmission. So we get it out on the ground, tear it down and find the bearings are fine. Fuck

But the input shaft which has 4th gear on it, as a part of it, is scored/damaged. As well as the countershaft front gear. These are the 2 most heavily loaded gears in the trans as they supply power for 1st, 2nd & 3rd gear. For a minute I'm like shit, wtf am I going to do.

Then I remember I still have my other trans

So I grab it, we rip it apart, the gears look ok. Sweet. Grab the input shaft and countershaft out of this transmission and clean them up. They're going into the trans I just blew, 2 trans into 1 (hopefully) good one. I figure I may as well replace the input shaft bearings on this one (they were already ordered), but I'm going to leave the countershaft bearings alone.
But wait, the drama isn't over yet.

This last saturday (before the trans removal) I do an oil change on my truck, and I noticed the coolant level is low in my reservoir, so I top it off and yank the radiator cap. It's low as well. I think, "Man, where the hell did the coolant go?"

I get home, pop the hood. Great the front edge of the hood is soaked in coolant, and staring me in the face is a 4-5" long crack in the plastic top tank of my radiator. Fortunately I know a few suppliers, 800 radiator has a warehouse in town. Gave them a call. New radiator $146, called @ 8:50-9am, radiator delivered to office @10:15am. Got it in and running that tuesday night

Yesterday night picked up my input shaft bearings & new speedo gear. Stopped by Marvin's (The guy with the ZX750RR) and pressed on the main front input shaft bearing.
So hopefully I'll have this thing back together tonight.
