2011 M8

There is a single row bearing that is prone to fail in the Diamond Drive. Do a search here on the forums on "Diamond Drive Bearing" and/or call Black Diamond Extreme. They will get you set up with a bearing. Or tear apart the Diamond Drive and see if the bearing has been updated.

Keep up on the Diamond Drive oil changes and ride it. Its a great sled.

Other than that potential diamond drive bearing issue, they are similar to the M7 for gas, oil, and go riding. Can and some sort of modification to the running boards to shed snow and ride it. A good suspension revalve is good for anyone. Especially if you feel you are getting a bit on the worn side.

2009 -2011 M steering have high resistance. been told installing the 2007 or earlier spindles will make them steer much easier. Just need to grind down steering stops so you won't lose steering radius

Congrats on still getting out there and getting after it!

Agree that the dd bearing needs checked if u dont know what is in there.

Also, inspect the primary for cracks in spider and make sure spring isnt broken. I dont think springs were an issue in 2011 but were in 2010.

Oh, and the oil tank cap doesnt fit the best and/or the tank neck is weak cause they warp. I put some duct tape around the grip part of my cap and then installed a hose clamp over that and it allows me to snug it up without warping or jumping threads as u snug it. I tried the aluminum neck insert and like my method better. 2010 M8

I agree with the recommendations made by the rest of the folks.

At this mileage, I would remove all the shocks and send them to Andy Youngstrom at Gasshockrepair.com in Rigby Idaho. Have him refresh the oil and seals and he can revalve them for a more compliant ride if you would like. He does it very inexpensively and i bet it would be roughly $100 (give or take) shipped to get them all done.

Yes, it's true the 2008 and earlier spindles steer MUCH easier than the 09 and later. I put 07 spindles on my 09 and it feel like it has power steering now. I love it. If you would like, I have a set of very nice 2007 spindles for sale in the swap meet. Heck, I'll even add a link for you.

As the others have said, good for you for still getting out there and tearing it up. I admire you and hope to one day emulate what you are doing. Thanks for being a great role model for all of us.

oil cap

I did not only the neck insert, but also the RKT cap. The insert by itself wasn't enough to satisfy me as it started to get funny after about a year and a half.

Age 73? That is awesome and I hope I'm still riding at that age!
