We dont seem extreme conditions here; so that's not that far off if those are what the oem recommends.


We had a 00 740i come through the shop w a smoking tailpipe(only after hot and hard acceleration) burning oil. Customer paid extra for synthetic oil when bmw requires a standard crude oil. I gambled w the customer I would pay for bmw's castrol syn oil to be put back in IF the standard oil didnt stop the smoking... it did.

Just an idea... synthetic oil is alot finer and maybe sucked up easier past the rings if the bike's engine wasnt designed for it. Again, Im a factory car guy first, bike tinkerer second and Im not familiar w the 250r design, so dont quote me. Just some ideas. Motorcycles Unlimited is open tomorrow, they may have some advise/info if you call.

the last motor in my bike did that. i was adding a quart every 3 days as well. no leaks, no smell, no big exhaust plume.........until i let off the gas, and was engine braking. thats when friends said something is really wrong. under hard accleration/idling, nothing else shown signs.

see if another person can ride behind you a bit back, and try different riding/throttle input. at some point you should see smoke, if none is ever found on the ground.



edit: you could have a leak, that only does such, when the bike is running, when the oil is thinner, and getting sloshed near a leaky gasket somewhere. the bike never left its mark when turned off...but if it ran for 15 minutes, just at idle....it would then drip. but stopped the moment the bike was off.

have M.U. take a look at it again, when you get the time.

thanks for the advice guys unfortunately by the time Im off work and make my way back towards 1960 Motorcycles Unlimited is closed so i won't have time to run it by there till saturday but ill try all your suggestions starting with running it for a while tomorrow morning. when I say it wasnt running right i meant usually I twisst the throttle and it feels like it's pulling me (this is freeway speeds 60+) but on the way back home today seemed like it was lacking on power still got up into the 80's but seemed like it had to try harder to get there may have just been my mind playing tricks on me.

That was probably my girlfriend that came in there. Her tailpipe smokes after hot and hard acceleration.

HOV is nice, except for when reg traffic goes faster than you. or when there is a slow azz in the lane, or when someone breaks down

i did150 in HOV once, it was alright...

This situation was probably over 5 yrs ago. Did they resolve her problem?

*Update* so I pull into the parking garage this morning downtown and park my bike she was running like a champ no problems the entire way. I begin taking off my gloves and helmet and what is it I smell? burning oil S**T, I look down to investigate and there are small drops of oil leaking from 2 hoses towards the back end of the bike S**T. I get down on my knees and look under the bike and it seems like oil is leaking from multiple points in that area (not too familiar with bikes yet so I can't pinpoint exactly what it is that is leaking oil, now I kind of wish I took a picture of it). So i'm walking to work thinking ok this might not be a big problem and I notice one of my shoes is shinier than the other my shifting shoe (Left for those having a hard time following) has oil all over the front of it so now i'm sitting at work counting the min. till Motorcycles Unlimited opens so I can call, very dissapointed

I wouldn't have rode the bike to work knowing there was an issue. When my car starts acting up, I fix it or take it to a mechanic...I don't continue driving it.

The bike does not call for syn. I lost some good amount of oil AFTER driving a good 1k miles after my oil change. According to Patrick, the 250s generally burn oil esp when driving on the higher RPMs. Ever since then I always peek in my window every couple of days.

Unless you drive 500 miles every 3 days it shouldnt be that bad.

Oil travels down then back(due to air flow.)

Look for clean lines in the oil grime(shows a larger leak due to oil flow carrying grime away.

That was supposed to be a joke. A bad one but a joke none the less.

The tubes on the back of the engine are generally connected to the airbox and are there so if the engine is overfilled with oil it blows out of the engine cases thru the breather and into the airbox. The oil is then run through the carbs and into the engine where it is burned as you drive. This prevents overflow from going onto the road unburnt. If you overflow with a quart, expect a quart in your airbox. It won't happen at idle because you don't get enough pumping forces in the engine to push the oil up the breather into the airbox.

My guess is you are just overfilling the bike. Run it for 2 minutes. Shut it down. Hold the bike perfectly upright for 30 seconds. Check oil level.
