Counter Shaft Sprocket Nut Removal Horror Story

I put new chain and sprockets on my Vstrom expecting the counter shaft nut to be tight with a 24" breaker bar and my wife standing on the rear break. I went to pull on it with all my strength and almost fell on the floor it was so loose.

Yea, I'm with you on that. I have good reason to believe that nut had not been removed since the bike left Japan in a crate. It's like it tightened up in service, although I don't see how. Far as penetrating lube, I covered it in PB Blaster for two days prior. Made no difference at all, that I could tell. As one poster mentioned, I thought for a while it had been red locktighted. That's why I heated it before the 3/4" IR gun removal attempt. But after cutting it off, there was clearly no evidence of thread locker. It's a conundrum, for sure!
I'll try Richard's suggestion of witness-marking the nut after I get/install the new one. Thanks Richard!

Ha, here in the Philippines torque wrenches are never used..just reef on it as hard as you can. Even oil fiiters are way over-tightened.

Yeap, I've never encountered a nut on as tights as these. Although, I hear after you bust the nut the first time it's easier next.

I didn't have problems with either of my KLXs. Doing the sprocket on my 650 was the first time, seeing sprocket wear and the OEM tooth count tells me the 250 was too. Used an impact on the 250, don't remember on the 650.
Once torqued on with the new sprockets I've not had a problem with either bike. Impact off hand tool on is definitely the ticket. With the tab washer on the sprocket bent over the sprocket would not move unless seriously loose allowing enough play to wear the washer teeth. Thus the reason for it. I would have no problem installing the sprocket and tightening as tight as I could with a ratchet (12"?) having that lock tab washer on it.
