So he actually has bearing failures, or he's following some prescribed replacement schedule?

Do the other guys he rides with on KTM/non-KTM have the same issue?

He's having bearing failures from what he tells me and on both of the KTM's that he owns. I'll find out which models. He says the other guys with KTM's have the same issue but the Honda's & Suzuki's are fine. This guy is an experienced rider and when younger was sponsored by KTM although not on a paid, factory team.

This is happening on the 300XC and he says it happens to all the guys he rides with that have that bike. Supposed to be a big torque engine that just over powers the rear. He says that when he was racing the smaller bikes, a 125 and a two something, that there were never any issues like that.

300cc 2-smoker?

Odd.
Perhaps it's got some peculiar geometry that funnels grit to the seals.
Or perhaps the wheel or spacer puts too much/not enough preload on the bearings.

In a past life I did a good bit of design work on gearbox/driveline stuff.
By the time you get a shaft big enough to carry the power, even the lightest-section bearing was usually up to the job.
A typical wheel bearing has a load rating of ~2000 lbs, and you've got two.
And bearing load ratings are *really* conservative.

I keep telling him it's because he's installing them wrong.   

He says it's because they ride the ever lovin' piss out of those things!

I think we need a little more orange talk in here. 

Just doing a simple oil change last weekend, I had a weird angle with the socket on one of the oil filter cover screws and thought that was why the screw wasn't turning in very smoothly...

I was wrong.


I was worried about snapping an easy out off in the bolt as I have done in the past so I got some left hand drill bits, center punched the broken bolt and started drilling.  I was hoping that the bit would encounter some resistance and start turning the bolt out, no such luck, drilled all the way through it.  I didn't have any choice now, I drilled it with a 3/32" bit and got out the easy out.  Using the clutch on the lowest setting then slowly applying more and more torque with the clutch settings it finally came out.



I was so happy it came out, I wasn't sure what I was going to do next.  I tapped the threaded hole in the block and put it back together with new M5 screws.  Everything has somehow been much more difficult with this bike than any other bike I've had but I love the bike and am still having a blast with it.

Nice job!

[MadDuck]

It's great that you love it because sometimes some bikes/cars are just that way.

Awwe yeah!

Finally spotted in the wild, an 1190 ADV in downtown DC. Aside from the display ones at a show, first time I've seen one

Just signed up for supermoto school at New York Safety Track.   Only 12 spots available, taught by an AMA SM champ I haven't heard of, Corey Alexander..  Should be fun.

Woot!  Videos are demanded!
