Congratulations! Read all the pinned forums. But mostly it's a reliable dirt bike with a four stroke motor. Service suspension, check valves, tune to suit your needs and enjoy.

Welcome to ThumperTalk Dan! And welcome to the Yamaha family! As Rocky said, the Yamaha's are very reliable when maintained correctly. The three best things you can do for your machine are the following:

1: Get a Yamaha manual. This will save you hours looking up torque specs, cable routing, etc. etc..
2: Check your valve clearances! One reason that your machine might have backfired is a tight valve. It's not the only reason, but tight valves will shorten the lifespan of your bike!
3: If you have any questions, look on ThumperTalk! Were all here to help!!! :thumbsup:
