They made decent horsepower, they were just built better and with better quality components.
Things/times have changed, but I still would not hesitate to purchase a current two stroke, and certainly would not fear holding it to the bar.
I'm not a four stroke sled guy - not sure I ever will be.
I guess like everything else, I'm stubborn, I like what I like and will go down the with the ship if I don't want to change.
