I am new to Quads and reworking a 1996 Blaster that was partially disassembled to get my education.

I do not have a reference to where the large line from the crankcase, just in front of the kickstart hooks to on the blaster. I also am not sure where the oil line from the container, under the seat, hooks to on the carb. Can someone help me either or both questions? These are the last two items needed to try and start-up the beast.

Thanks

From the factory Yamaha blaster's had oil injection. There is a small oil pump under the right front side cover that turns with the crankshaft and pumps a specified amount of oil with each revolution. There is a supply line (from the tank) into the pump and then a line to deliver the metered oil to a nipple on the right side of the carburetor.

Most will tell you to do away with the oil injection system as they have problems with the plastic gear inside the motor (and have generally been suspect since their invention) and just premix your gasoline with the proper amount of oil. With proper care the oil injection system works fairly well as long as you're not trying to modify your blaster (and have to desire to premix your gasoline).

Go to the general support section of this forum and download the service manual. It's worth its weight in gold. These are fairly simple machines but some serious damage can be done if you don't follow specific processes while working on them. The service manual will walk you through the steps to purge the injection lines so you don't run your engine without oil.
 
The large nipple on the crankcase sounds like the vent. Normally this large hose is routed up to the front, near the steering stem. The point of this is to keep it out of water. I have seen others route them to other places for various reasons, most of them aesthetic. The far end of the hose stays open.
