just did 60000 KM service.
changed the oil and oil filter and the collant(for flash purpuse, just in case)

the bike runs smooth, strong and great.
so the rebuild went good
Cool to know your rebuild have been ok :)
Hope my bike doesn't break at 50k km, i do over 35k km every year... and i want to keep this bike over 3 years without any expensive repair (and i can't rebuild it myself...) :D

How are your wheel bearings?
i am at 64000KM and the original bearings still good.
my father changed his front wheel bearings at 32000KM.

mine rear shock degraded , it almost don't have rebound so i going to change it soon.
the front disk is on the last pad set, going to replace.
the front brake micro switch started doing me trouble, so it's going to be changed.

BTW, still with the original rear sprocket and changed the front sprocket only 1 time, now on my third chain.

Now I bought BMW F800ST,
Passed the cbr250 to my girlfriend.
Now on 76000km runs fine.
I have tested the BMW F800R two days long, the motorcycle is great, but in my opinion too expensive compared to the competition. Unfortunately I have read about many cases that have troubles with the engine, many engines fail between 70.000 and 100.000 km. Please keep us up to date how the engine works in your case, if the engine should be more durable than expected, I will think about buying that bike. By the way: the engine is not made by BMW, they buy it from Rotax and install it into the F800 Models. Anyway: I wish you a lot of fun with your new motorcycle, ride safe!

My friend with f800st also did 140000km
Only the known alternator problem showed up.
I hope you will be able to ride much more than 140.000 km, but in the past there were some problems with the 800 Rotax engines, some failed after about 3.000 km and were then replaced under warrenty by new ones, others died after about 70.000 km, that’s what I read on forums, maybe it’s not a problem generally, maybe something like the stunning or overfoldding problem with our CBR250R, some people experienced it, many, including me, fortunately not, not under the so often described circumstances. But please don’t forget updating us how your or now your girl friends CBR250R runs, thanks in advance!

"stunning or overfoldding" problem with the CBR250R?

Can you elaborate, as I have no idea what those terms even mean... :confused:

I mean “stalling” / “flooding” of course, as you know some riders have the problem that the engine unwanted turns off while riding. Here is a link about that problem, which you know about:

http://www.cbr250.net/forum/cbr250-problems-issues/2100-my-cbr250s-engine-turns-off-when-downshifting.html

Some have a theory that under special conditions too much fuel is injected, that can’t be burned, which leads to a flooding with fuel and the engine turns off.

Wow I actually sat here for an hour reading this whole thread. Why? I just got off a long day at the office. My father and I always debated on what works and what should be done or not. One time he told me that there is always tried and true methods but they aren't the only methods. Wish I learned more from him when he was still alive. As my father was a math whiz but never got the always correct answer the "proper" way. Great job on the rebuild and may it last even longer

I've got 70k km on my bike, and haven't had any of the same issues.

So far I've had to change the clutch plate, and the stator, front disk rotor.

Think that's it besides the service stuff and chain and tyres.
