hi ChinaV!

Thank you very much for your help offering!

My bike is working perfectly. It has around 6500 kms so far. I bought it new on last october 2010.
I use it every week day as my personal transportation to work. I do 30 kms to work and again 30kms back home every day. Most days with my wife on the back seat.

The bike is awesome so far.
Here in Argentina is a good selling bike and has the best price/product ratio for me and their competitors are:

Yamaha YBR/YS 250 u$s 5750
Honda Twister CBX250 u$s 5250
Bajaj Rouser 220 u$s 3250
Gilera G1 250 Naked (another chinese bike Yingang YF 250NF) u$s 4000
and other 250cc chinese brands (there are plenty of them) u$s 3000 to 3500

My Beta Chrono 2.5 is worth aprox. u$s 3200

The quality of my bike is similar to Bajaj's but a little inferior to Japanese first Brands.

The mayor problem we have in argentina with our QM250-2D at the moment is that the axle of the intake valve swing arm is having some unusual movements. It should be fastened and it shouldnt move. But it swings. On some bikes more, on some less. We told this matter to Beta Argentina and there are making an investigation about that.

Please, can you tell me if you experienced this on your bikes? Can you please do me a favor, and with your engine running, touch with your fingertip the axle of the intake valve swing arm and notice if it swings?
As we could made research between several bikes, it doesn't matter iof it is brand new or it has 10.000 kms it swings. We asume that it is an manufacturing problem.
Can you help me with this issue? Maybe if you have any contact at QingQi do some questions about it?

Thank You for your hospitality and I will now take a look to the link you posted.

See ya!
