So everyone raves about how reliable these yz250fs are but I’ve had atleast 6 different friends each blow there bike up within 30 hours, weather it be valve, rod or timing chain issues. had another buddy blow his bike up at 12 hours this past weekend from sucking in dirt, it’s also important to mention they all do the proper maintenance. I’ve had 3 250sxfs all over 100 hours and never had a single issue, I’ve been wanting to switchover to yamahas just to try something different but these yamahas blowing below 30 hours is kinda scaring me away. And I know some people have had plenty yamahas without issues, but I’m questioning that reliability quote.
i had some big troubles with my 19 yzf aswell, well taken care off.

These two sentences can’t coincide with one another lol. If you do proper maintenance, you use grease on the sealing surface when installing the air filter for a proper seal which doesn’t allow dirt to get in with proper filter oil in the filter on top of it.
There is a reason Yamaha is known by everyone for reliability, because it is.
Signed, your friendly KTM owner.
The only issue we had was a wire off the quick connect for the start button broke. It was due to a top over or the pressure washer? Not sure but its all good now.
The timing chain was upgraded in 2021 but its still a good idea to replace within 50 hours.
Good Luck!
I am curious because I have a 14 year old who is now almost 6 feet tall all of a sudden. He looks like Arminas Jasikonis on his supermini...
Shit happens, people grossly overstate their maintenance/riding abilities, and sometimes you just get lucky/unlucky.
Only thing I'll ever say is stay away from Hot Rods cranks lol

If he sucked dirt then he's not doing his mantaince correctly and who knows what else he screwed up.
Is that pretty common or just random? I've not seen it happen to another bike personally, in the real world.

Another thing to note, iirc the YZ250F is the sales leader in racing dirt bikes in the USA, so there are lots of them that run without issue and you never hear about them.
Fresh Rotella every couple rides. Clean/re-oil the airfilter as needed.
I put in a set of clutch plates at 83 hours, the OEM looked great.
The only thing I've had fail/wear out prematurely in my opinion is the starter system. I've rebuilt the starter 3 times. Glad I have the kickstart backup.
Figure I'll continue riding and racing as I have been until it starts making noise or won't start. Then I'll rebuild it and start all over.
I don't moto much at all, just A class off-road racing.
