Welcome!

Nice looking bike. May we see some more close-up pics?

yes sure ill post some more pics soon but you can see bigger resolutions pic if you click on it

I've never seen a twin cam China motor; how does it run? Any trouble with the cooling system?

run really good before i have the DF250rtc bike , and this one is a lot better more torque and better output on the highway 140km/h at 6000 rpm with 2 people on board, the cooling is ok ,some times get temperamental?? build to much pressure and leak a litter bit on the reservoir tank cap but that is if i fill up to much. other of that i'm really impress with this bike .

here is a pic of my old DF250RTC

So, you've had three China sport bikes?

That looks like one of the most inteseting bikes I've seen in a while. Is it a derivitive of the NX250? I like that bike.

no 2, the white one on the pic, and now this yg250, but if count before of this bikes i owned a 150 cc chinese scooter here is a pic of my old baby.

well the engine is a almost exact copy of the nx250 , is just different on the cooling system inlet to the engine, but internally you can switch most of the parts like oil pumps , cam chain, tensioners and several other parts.

Welcome; we are glad you joined us. :hi:

That is a great looking motorcycle! :tup: Please tell us more about your modifications to this bike. :)

thanks for the welcome.
i removed the SAE. i change the air intake system(removed filter box, put filter to carb and engine breather),change handlebar ( one 2 inch lower) to give a better look, change levers, aluminium mirrors, rejet carb,change all hoses to better quality ones, led city lights ,front sprocket from 13 to a 15, new cylinder head and and valves ,and now ill change the muffler to one with less restrictions.
