A couple holes in the baffle do some good, jetting you just gotta figure out. If you fuck it up and drill to many holes, metal flask funnels make excellent replacements. One thing to look at is the header pipe. Some of them are factory crimped at the end. If it is, cut the crimp off. Also, the fast header is about 1" in diam and has 5 holes drilled in it. From your profile pic, you have the pipe that starts with a small diffuser and then comes to a long cylinder with the baffle stuck in the end. There are two plates in there with holes drilled in them, I have no advice as to what to do with them, but they're in there clogging up the works. Pipes work on acoustics, it's just sound, keep that in mind. Don't dremel on your jug, it's fine the way it is. Garelli's are pretty well ported to begin with. Unless you've got the 36 tooth rear, or the 9 tooth front I wouldn't muck with gearing until you've got more power to play with. Optimal for stock NOI is 10/32, fo' serious. Unless you can find an 11 front. But good luck with that. You already have the curvy intake. Dremel your 14.12 to 14.14. Upjet. Try different shitty 30 weight oils in the tranny until you find one you like, then tune oil level. I'm kinda tempted to go gut a Garelli pipe...
