Madrigger,
Seeing as how everyone is on the 2-stroke waggon I put in some for the 4-strokers. Having a four stroke does not mean you will have to go and get a degree in engineering. They are different thats all. Look at it this way if you have to learn about a 2 Strk or a 4 Strk what's the difference? You still have to learn right? I'll take that a step further, GENERALLY SPEAKING (so don't send me messages boys) for all intensive purposes: 2 Strk guys don't know about 4 Strks, and vice versa.
It all boils down to what you think you are. If you like the speed go with the 2 Strk, if you like the big stuff or warbirds then go with the 4 Strk. Catch my drift?
Finally just to make this as confusing as possible if you think your gonna be a "Pack Rat" like the rest of us and intend on accumulating WAAAAAAAAAAAAY TOO much gear then it really dosen't matter, you'll end up with both anyway!
