Shift rod problem, maybe gasket?

[H2only]

my 05 450x has sitting for a couple months because of winter, I noticed a few weeks ago a couple drops of gear oil under the bike. It seems to be dripping a couple drops over a 2 week period or so, it is coming from the area where the shifter rod goes into the transmission. It has never had any sort of leak before, and last time I rode it I had the average get offs, but nothing out of the ordinary. I also noticed a single scrape on the shifter side case, it is a scrape that exactly matches where the shifter end makes its arc when you shift though the gears, so it obviously hit on that side at some point. The shifter lever itself is not bent, so it must have flexed along the shift rod area which is where i think the leak is from, could it possibly be a deformed seal where the shift rod enter the transmission, or should I be more concerned about something bigger? It shifts fine btw

look closer, most likely the countershaft seal, not the shifter seal.

ok, went out and looked a little closer, there is some gear oil on my front sprocket as well, so that must be it. How hard is that to replace?

[Dust_Devil]

Not hard, get a service manual. Contrary to popular belief the clymer manual is fine if you can find one instead of the factory service manual.

Pull your sprocket and inspect.

ive actually bent a shift shaft before, and that sucks balls when you have to tap the shifter to the mid position to grab another gear. it also dripped a bit of oilbecause of that. simple fix though.

I have the exact same problem as you H2only, I just noticed and I am about to go take a nice close look... So have you had any luck? Fix it?

actually, I left it alone, I have ridden it a number of times and it has not leaked since. I have changed the oil and tranny fluid twice since it first appeared as well, no more leak.

Well FYI I ended up replacing my seal on the countershaft and it's been #1 ever since! Just had to heat the shaft and look the seal to make it slide in there and it was flawless... had fun doing it.
