1981 Suzuki gs750e needle jets

[Sgagne199]

I have tracked down and purchased 3 nos needle jets for my gs750e. I am in hopes somebody on here can help me find a fourth one. It is a Y-4 needle jet I need. Mine on my bike are worn out and are in definite need of replacement. Any help would be greatly appreciated

The main jet holder tube (incorporates a needle jet function) is SIZED Y-4; the Y-4 is the code for the diameter of the hole. There is also a BADGE number that indicates the series of the needle jet (main jet holder tube) and each series has a different conformation. Once you know the badge number you can search for the part you need at various carb parts sites:

You can also use the Partizzla.com parts fiche to get the part number and then plug that number into their search and find out what other models it was used on. I did this and found you part on eBay (searched for SP400 needle jet):

Thanks for the advice I have been watching Ebay everyday and I want to find a new one because I am worried if I buy used it will be worn also. And unfortunately Suzuki discontinued the part

I have some Y-4 emulsion tubes.

I have some Y-4 emulsion tubes.

Are they new and if so can I buy one off you? I already acquired three on eBay a while back and need a fourth one to get my bike straightened out

It is not new but I'll clean it in an ultrasonic cleaner so it will work fine.

Emulsion tubes on these bikes do not wear and as long as they are clean they will work perfectly.

Don't waste your money on new emulsion tubes. Unless there's some serious issues with the needle jet, the emulsion tubes simply don't wear out. The can clog, but they don't get warn. Low mileage doesn't apply here. If yours are worn then pick up the one from Chef and look at the condition of your needle jets. Something is very wrong if your jets are worn out.
