I'm probably over cautious but anything that has a wet clutch, with the same oil feeding the engine bearings, I change every 3 hours. I'm not as worried about oil breakdown as I am about bits of debris getting where it shouldn't be.

I guess my cbr, v-star, XT, and Maxim need to be changed more often than 3-5,000 miles.... Your oil filter is supposed to catch the wear particles that are big enough to cause damage, or are we removing filters to save weight now? Just remove the oil pump while we're at it and throw in premix, some of you change Pistons every ride and sell your bikes at 25 hours....

When and where did this craziness about 3 hour oil changes come from? Does anyone know, was it some jackass on a forum hazing a new member telling them "you gotta change your oil every ride or your bike will blow-up"?

I understand what you're saying but it's not a fair comparison. Why can a truck go 20k, a street bike go 3k and a dirt bike go a couple hours on oil change? Different applications and different abuse.

I will add, a very reputable engine builder told me to not go more than a few hours on oil, in the name of engine reliability.

Disappointingly, this story ended with the bike shop tearing down the engine and finding a few more pieces of spare clutch pin and no other damage. Reassembled and I raced a LL regional and destroyed my shoulder. That was 2 years ago and I haven't even washed the bike yet from that race, but that's another story. 

So the conclusion was that a rogue clutch pin was dropped into the engine during manufacture. It found its way to the bottom of the engine where it was held in place by the magnetic drain plug and must have been crosswise across the drain hole. So when I drained the oil it just sat there, and I never poked my finger into the hole because, well, you don't ha ha!.  I changed the oil every 2 to 3 hours and the bike had almost 30 hours on it at the time.  I only discovered it because it got dislodged while riding and I heard a crunch and the bike stuttered a little.  I did an immediate oil change and discovered the broken clutch pin, then came on here and wrote my original post.

THE END.

Cheers

This is still baffling.

Your bike was a 2016. From the factory this rogue clutch pin is dropped in the engine from new. It floats around the engine for multiple oil changes before showing its face. 
 

My 2021 has the exact same issue.  This pin shows up in an oil change after 80 hours. Engine and gear box work normally. No pins missing from the clutch. 
 

anyone with intimate knowledge of KTM engine assembly recognize this pin?

Not sure what it is but 10 hours on an oil change sure seems like a long time to me

Yup! 5-6 hours at the most for me!

I thought it might be a clutch pin but it can’t be because all my clutch pins are fine. I run a Rekluse Radius CX fully auto clutch which at 55 hrs the EXP plate broke into pieces but stayed together inside the clutch basket, including all the pins. Last oil change was 50 hrs and this oil change is 60 hrs.

This is a hollow pin with the same OD as a clutch pin but, to the eye, its wall might be ever so slightly thinner. In any event, it’s not complete so I have to assume there’s the rest of it rattling around in there. Any ideas what it is and how I go about fixing it?
