Actually I've been reading your local forum before I bought my bike. Unfortunately I can't post in your forum since I have to use google translate to understand what you are writing. However it has been very interesting reading Gligoras adventures with his bike.
It seems that there has been an update of some components för 2010 years model. I think they can sell the bike with other components if you want. The company I bought it from here in Sweden claims there is a "performance carburettor" that they have ordered with the bike from China.
However the bike has 520 km on the clock right now and no problems so far.
