Hi everybody, if someone know couple places in KM not far from center where I can repair my motorbike?

Try this.
Google [kunming map].
When the page comes up click on the map.
When the map comes up, in the search box, type 'motorbike', a range of pink arrows and dots will appear. Hover over the dots and the names come up (in English), some repair shops will be specific to your brand of bike.

First Ring north, about hundred meters east of the river, behind one of these little police posts. Good guy, professional.

North East corner of Jiaoliong Lu and Xiyuan Bei Lu, they good, fast and honest.
