Well mate let me tell you from experience it's never a good idea to purchase first and ask questions later! Lol
Correct me if I'm wrong spanner spinners but it looks like a lifan 110 estart? Imho anything less than $150 providing everything works without the battery isn't too bad.
Good little paddock basher to learn mate, don't spend too much on it and sell it off to the next young bloke looking for a cheap little bike.
There are plenty of threads in here to fine tune your little steed, give us a yell if you need anything!
Cheers
