Hello ! I am 56 years old and live in Vienna Austria. Have a new Grand Dink 300i with 1500km, and always have oil in the tube out of airfilter box. Dealer says no matter is bleeding from crankcase. Oil level was a bit too high so I reduced it, cleaned airfilter, box and tube but still oil is coming out. Before I had an 2005 Grand Dink 125 ccm and never had this problem so I am little bit scared. Hope someone got an idea. Thanks in advance for your help !!

Yes sir, when refilling the gear oil upon change you are probably putting too much in. Are you measuring the correct amount per the owners manual or just filling til it runs out the fill hole. If the latter, then it's probably getting overfilled. Might think about cleaning out the tube next time you change the gear oil to make sure that no residual oil from the tube is spitting into the airbox giving you a "false reading" next time you check it after a change. Of course you'll refill the the exact specification from the owners manual.

I had the same issue with my Super 8 150. Dealer said it was normal to get a little gear lube in the air box, even if it's filled to the proper level.
What I did was put a small piece of foam sponge in the air box, in front of where the breather tube comes in. Any oil that does come through the tube gets caught by the sponge, and doesn't spray all over the air box and filter.
At my last oil change, I had no oil on the inside of the airbox to clean up. Just a little in the sponge. I just washed the sponge with warm water and dishwashing soap, and dried it out with a hair dryer. Put it back in, and good to go!
And no more oil in the air filter clogging it up! 8)

Thanks Folks, Oil change was made by dealer it was the 500 km first service of engine oil. I Think they put too much oil inside. So I will wait a little bit, maybe its getting better, if not they have to check the engine on garantee
