Re-jetting 83 1100 E

[Mad GS 750 E]

Hey I got a V&H header used (but never been on a bike) that i'm going to install on my 83 GS1100E. I got instructions with it and they say run a 122.5 main jet ,47.5 pilot jet and remove the airbox cover,has anyone ever done this or heard about it? I'm leaning towards going with a K&N filter in the stock airbox ,what would the jetting be and how do i adust the needle #washers ,size, placement etc.. The pipe has a baffle and i live in massachusetts .Thanks for your help in advance.

You need to get adjustable needles also. A Dynojet, or even better a Factory Pro jet kit, will make this a LOT easier for you to get running correctly. Ray.

Ray I take it you like the Factory Pro kits better/

I'd try it stock and see how it runs - the factory exhausts on those bikes actually worked pretty well.

I really dont have the cash to buy the factory jet kit now,does anybody have the same bike(83 gs 1100 e) with header that can steer me in the right direction on the jetting ? thanks

I can sell you the adjustable needles for 65 bucks shipped to you. Ray.

The jetting that V&H recommends is fine. I would look into the needle that Ray sells though.

I have never heard of an 83 gs 1100 e, is it a V twin?

Yah its a v-twin ,with ape hangers, im suprised you never heard of one ! :lol: so anybody got anymore advice on the jetting?

 

[rapidray]

Yes, buy the adjustable needles! Even if they are from someone else. How many of us, that have been DOING this for YEARS, does it take telling you that for you to get it? Ray.

I realize you don't have the money for a jet kit but that's what needs to be done not only for a good running engine but one that keeps running.
I've blown up enough motors to say this.
Put the 122.5 main jets in there and shim the needle until you have the money for Ray's needles, DJ or factory Pro kit.
Rays needles are the deal I'd jump on.
