Main jet removal

Postby Barry Barker » Tue Aug 07, 2012 2:41 pm



How do you remove the jets on these early keihin carbs? I have never seen jets like these. No slots, no hex head, thanks for your help.

I do not know what the goldwing carbs are like, but some old carbs had jets that where pressed into the carbs so they could not be changed (to prevent messing up the emissions). It may be that your carb jets cannot be changed, but hopefully someone more knowledgeable than me can give a definite answer.

I have never seen jets in a true GL1000 not be unscrewed. The GL1100's are all like that. Is it possible you have 1100's ?What is the carb number stamped on it?

Anyway, the press in jets can be pulled by screwing a sheetrock screw in to them and pulled, or some other means of attaching to it.

Thanks guys, I just cashed in the benifits of using a local service manager for small ATV repair. He informed me that early keihin carbs had o-ring pressed in jets. A bracket holds them in place by attaching to the jet via a slot and then resting on the float bowl. Thats what I have, lots of penetrating oil and elboe grease with pliers and they are all out. Now I am soaking the jet tubes in carb cleaner using aresol spray can tops. Hopefully i can remove the idle jet and emusltion tubes once all the gunk is removed.

Are you talking about the two emulsion tubes in the carb body that sit under the secondary and primary jets

Yes i am talking about the tubes under the jets. i have found randakks site and will be buying parts from him and am following his instructions. Hard to argue with instructions like his!!!! The idle jets are stuck, I hope i did not damage the slot on one of them, but i think i did. They are soaking for the evening, maybe 2 days. Using the paint caps i can just soak the jet tubes.

Thanks for the site, I now feel confident I can make this thing run right, pictures are worth a thousand words!!! Got the carbs all apart, soaking the jets and emulsion tubes, only broke a few screws, but i got the remaing studs out. i used a cut tooth brush and a hammer to get the emulsion tubes out, one took about 10 min to get out, it was stuck, and that was after soaking all night in carb cleaner. Someone tried to clean these carbs before, it apprears they gave up early, thats a good thing. Jets are all plugged, emulsion tubes plugged. Judging from these carbs I can almost bet my buddy who owns this bike has never riden it running properly.

I need a bushing for the choke linkage, guess someone before me lost it, has anyone got one, or can direct me where I might find one? Here in Bismarck AR, I do not have any resources for parts.
I
Additionally, How much is Randakks carb kit?

Thanks again, Barry

Yes, thats the bushing i need and the pricing for the kit is fair. Randaak is open for business tomorrow so i should be able to order parts.
i must say these carbs are a lot more involved than my VMax, way more parts!!!

Thanks, Barry

Anyone have a cheap float needle and seat. I damaged the seat trying to get it out. All i really need is a seat. Thanks, Barry

If I could spare $130 for spare parts I would jump on this.

Luckly, i do not need a complete carb assembly, but I did pull the trigger on all new float seats and needles. The more I thought about it the less I wanted to use the old ones. Barry
