    I think the pre epa will have larger jets as it comes however you still may have to change the jets to get the correct tune for your bike the epa carb should be pretty much the same as the pre epa carb just with smaller jets to give a lean mixture jets can be changed
    The cv carb uses 2 cables one to open and one to close the butterfly i hope you have taken this into account as your handlebar setup may need to be updated to suite
    Plug off the vacuum port if it is not required

    I don't think either will work. I looked for free end play but couldn't find it. You will have to get cables for '95 and earlier to fit you grip. The '95 and earlier screw in where the '96 and later pop in the throttle grip housing. You will also need a different manifold as the CV slips on the manifold and your present carb. screws on like an S&S. A S&S should bolt up fine and is a very good performance carb.. The CV will also wake your Baby up.
