Since the pwk spigot is shorter than the stock mikuni spigot there is a bit of space and then a lip where the mikuni usually bottoms out.

Should I trim this lip off to give a smoother flow at the intake?

There will still be a step down out of the carb, but it seems better than a step down then a lip.

Now bevel the carb outlet since you did that...about half will work better.
