I went through the same crap man. Constantly fixxing crap, everytime you make something better another part falls off. Then I made a long trip to the dunes and didn't have a lick of trouble for 4 days straight. Ran like a top and the 4 poke puked out. It's a coin toss. With the stuff I have the 4 strokes are all newer everything. The Banshee is a relic. I've learned the hard way which gaskets suck, what oils to use, where you can cut corners and where you need to overkill stuff. It's a learning curve just like anything else. Some of the stuff you've been having problems with can happen to anyone. Once you get those issues fixed right you shouldn't have to worry about them for a while. These things are really reliable once you figure out the limits. Just takes time, money and patience.
