Jetting advice needed

[fatboy666]

I just bought a full system fmf factory 4.1 with megabomb header. I have a dmc alien on it now. Does it need to be jetted any different especially with the mega bomb?

Doubtful you will have to change anything... Unless the Alien was a slip on, It should be the same. The megabomb doesn't do anything but suppress some sound.
