This is not always the case it sounds like your bike was put together poorly.my friend Josh has a yfz 450 and its down with some electrical, he still isn't positive what the problem is, I can put a new crank in my motor with the amount of trouble he's had with it this time.any machine 4 poke or even a banshee can last forever or have constant issues with a little good luck and carefully applying your skills, the banshee should do great. One last thing, you need to start reading the expiration dates on that gas chief! Lol
