i wonder if a similar effect could be acheived by filling the recess with epoxy and then milling/drilling out a recess for the cutout for the needle jet and cable nipple.
but the thought of reducing the pilot by 50% scares me.
i have some spare slides to try it out on if anyone else has sugestions or input.

This has been around for at least 5 years or so.....but I've not known anyone who has tried it/them. The theory looks sound....but only back to back dyno runs would tell the REAL story, IMO. Anyone got a dyno to put my 550 on ???
