I am just a little curious after reading more than a few posts about the XRL's having issues with counter shaft wear, what is the common factor? High mileage, poor quality sprockets, lack of maintenance? I know we have more than a few XRLs with more than 20,000 miles on the odometer. For those that do, have you replaced your counter shaft? If so, about what mileage?

IMO and from looking at my bike the previous owner had the chain on too tight. Also it didn't look like he ever took the plastic engine guard off to clean out the grease and dirt build up.
BTW: 9,000 miles and my Cshaft is all messed up.

I've got 27,000 miles on mine, there is some wear on the splines but not severe. I think it's poor fitting sprockets and popping the clutch doing wheelies. If it runs right you shouldn't need to pop the clutch. :confused:

Maybe the bean counters cheapened up on the heat treat?

If this is any comparison my cousin once had a '92 XR600R which im fairly sure has the same countershaft as the 650L. This bike had around 18,000 kms and was showing signs of wear - eg front sprocket slopping around but would've probably gone another 8-10,000 kms before needed replacing.

over 31k miles on my L and no real signs of wear. Keep them clean and lubed and they will last a long time.

Yea I had to replace mine. A little over 15k on the ticker. The previous owner ran hardened steel sprockets on the bike. He said they lasted longer. Problem was they were harder than the countershaft. When I found it out I was changing chain and sprockets for a Dual sport ride in VA that weekend. I got cheap and welded the new one on the shaft to get me through the season then started collecting parts for the build. I thought since I have to open the thing up I might as well go BIGGER.
I only run OEM or Sun Star sprockets on the front now. No signs of abnormal wear over the past 2 years.

Replaced mine at 8k mi. Had just purchaced used and while replacing what I think was orig. chain and sprockets I noticed the wear on the c shaft splines. Chain had been run very loose and the rear and lower front chain sliders were worn to almost nothing.

Since mine is low mileage I've never taken a look. I'm wondering if you're supposed to grease it or not. If not, would it help to do so?

Definately take off the sprocket and clean the teeth on the shaft and the sprocket. Then apply a light coat of grease to the teeth.

Make sure to use blue loctite on the sprocket bolts.

OK just took mine apart and inspected - looks perfect so I lubed it and reassembled with blue locktite. I'm curious though, even when the retaining thing is tightened down, the sprocket has some free play. Is this normal?

Yes, that is normal.

I'm just new at this too, so please feel free to correct me.

I would have thought that the metal that the sprocket is made from would be softer than that of the counter shaft. Is the counter shaft's surface not case hardened?

In other words, should we not be wearing out a series of front sprockets before even considering worn out splines on the c/s?

Also, would a good moly paste (70%) not be a better lubricant for the c/s splines than regular grease?

The sprocket should be softer. The problem is, not many actually clean the splines and lube them after.

Moly is probably a good choice.

Ideally you'd want the spline area unhardened while the tooth area was hardened like a mofo.

I wonder if you could buy the hardest spkt out there and temper just the spline area?

I would guess it's dirt/sand/debris that gets on the shaft that does the most damage.
