I recently bought my first bike, it is a 2006 Zongshen ZS250-5 Sports bike. 250cc. It has around 1700 miles on it, and according to the previous owner, it had been sitting in a shed for about 6 months before I got it.

Anyways, it starts up fine. However, I just took it on the highway for the first time today, and couldn't get it over 60 mph. It goes up to 120 mph on the speedometer, and up to 14k rpms, but I couldn't get it over 8k rpms either. I have to get it all the way to 4th gear to go around 40, and then anything above is 5th gear. With full throttle in 5th, it goes around 7k rpm and 55-60 mph, and I can feel it cutting out a bit like it isn't getting gas.

So, my question is: how do I fix this? Is it just a cheap bike and I am SOL? What do you suggest I do? I think I will take it to a local cycle shop to see if I can get it tuned up and whatnot, but I'm wondering if there is anything I can do myself, as I'd like to learn.

Many thanks in advance! I greatly appreciate your time.
