Rejetting '77 GS750

[Guest]

Got a 77 GS750 with Emgo pod filters and a Mac 4:1 exhaust. Haven't rejetted yet and I'm wondering if someone has a similar set up. If so what jets are you running?

If, your carbs came with 97.5 main jets, and you ride near Sea level, change the mains to 112.5's or 115's for a good starting point. If, they came with 105 main jets, try to start with 120's or 122.5's. Jets are cheap from Z1 Enterprises.
Good luck.

Thinking 125's with one clip down on the needles as a good starting point. Might be a good idea to pick up some 122.5's as well.

I think the 750s were all 102.5 or 105, but whatever you do get better pods. Those Emgo pods let sand through, don't flow much air and are hard to tune. it's nothing but a layer of screen, no filter media at all.

I was thinking of getting some Uni's instead actually. They do seem kind of crap to me.

Drill the old jets out to save money too....
