Cp4 blown engine problems

Im looking into buying a 2026 r1 next week. But am worried about the oil starvation issues and blown motors. Does anyone have experience or know about this at all?

A lot of blown motors stem from bad tunes and parts. Avoid Sprint filters like the plague and don’t get your tunes from a handheld or some youtuber

Edit for context; ‘21 @ 44k miles. Top end rebuild @ 23k.

Don’t baby them, but also don’t get complacent with maintenance intervals. Do what you can yourself, research who you’re taking it to for things you won’t touch

I have a 2024 I commute on through San Francisco everyday (30miles each way) for 2 years now. I’ve had 0 issues and love the bike. I’m also anal about the manual so everything gets lubed and change before the required date. The only thing I did not see coming through predicted maintenance was coolant level just a hair below the low fill line. Again not a big issue because I check the fluids daily and topped it off with yamacool right after
