I recently got a 2005 loncin 250, got it running, and it drives relatively well. I’ve only taken it on test drives, but it has never stalled or bogged out, starts right up and idles fine. I’m pretty sure it’s a Yamaha bear tracker clone. I changed the oil and diff fluid yesterday… the oil was black, diff fluid was like a grayish-silver. Also, I got new tires, and a new air filter.

I want to take it out in the desert (calm trails at low speeds), but I’m worried about getting stuck out there. I’d Ike to take it out for a couple hours. Should I be worried or should it be okay? If I were taking bets, what would you put your money on?

Here it is on a 15-20 min test ride and it did fine:

 

Chinese electricals are always a bit suspect, but older Honda/Yam etc, electrical stuff sometimes gives trouble too. Some Chinese bikes came out with poor hardening on engine and transmission components, so they wear fast or break, but on an older bike this would have shown up years ago. If you can, partner with another rider, so they can tow you if you do have trouble, until you are sure your machine is reliable.

 

I wouldn’t trust any one of those machines to take me around the block without having problems.
