Project 83..gl1100 carb rebuild

Postby scooter123 » Thu May 01, 2014 9:27 pm



Hello guys well after getting a new front tire I took the bike for a nice ride and noticed a little bit of fuel leaking from the carbs!! So I ordered 4 carb rebuild kits from Honda.....so I started the painful task of getting the carbs out......HOLY MOTHER OF PEARL!!!!! I GOT THEM OUT!!

Any tips and tricks on rebuilding these carbs??

Best tip out there: Take Your Time! These carbs can be quite picky. If you can, find a couple walk-throughs and read them first. Want the best? Visit Randakks site. If you aren't in a rush you can purchase his step by step guide. What ever you do, triple check it all before reinstalling. After, do a good carb sync and she'll purr like a kitten. Have fun, it's worth it in the end. Frustrating pulling the carbs multiple times, I pulled mine 4 times to get it right because I was rushing. Float height has to be spot on. That was my issue. Measure each one. They have to be the same.
    You only need two tools in life - wd-40 and duct tape. If it doesn't move and should, use the wd-40. If it shouldn't move and does, use the duct tape!

This article has a lot of good info: http://www.ngwclub.com/forum/viewtopic.php?f=8&t=12168
Clean carbs one at a time and keep ALL the parts for each carb separate - don't put # 3 slide in # 2 , etc.

Also, before you set the floats be sure they are not bent in any way. Getting the height set on the floats can be frustrating, as they have to be level heel to toe, but it HAS to be spot on in order to work, "close enough" simply dosent work. Let us know how it goes. Regards, Johnyy

Hi guys and gals.............I started the cleaning process of the carbs.....I've taken two of the carbs totally apart and I hope and pray with the help of this forum they will go back together!!!

I removed all the linkages and even the butterflies from the carbs.....keeping both carb parts separate.....there was a lot of old fuel and crud around the shafts so I ordered carb rebuild kits from my Honda dealer.

So my question is did I go too far in removing the butterflies from the shafts...there were these felt like O-rings on the shafts that need replacing.......I thought there would be rubber O-rings in there.. I wonder if they come with the carb kits that I ordered??

here is a pic after its all cleaned

So are you saying that there is no felt seals for this....or rubber o-ring.......or because I removed the butterflies from the shafts....which I think will be easy enough to put back into place.....but what do I know...lol

For my 83 GL1100A, I bought my carb kits and the 31 page walkthrough instructions from the Randakk site. It had EVERYTHING in it that I could possibly need, every o-ring, every seal, every cotter pin.

I disassembled the carbs simultaneously, but placed each one into its own container, and did the actual cleaning and reassembly one at a time.

I don't remember where I read it, but I do remember seeing this idea somewhere in my research before beginning the carb project... Carb cleaner (in a dip-tank) is really hard on the old aluminum/die-cast zinc (pot metal) that the Japanese bikes had in this era. Reportedly, too long a soak in a carb tank can actually leave the carb body porous. Instead of soaking in carb cleaner, I literally boiled mine (in distilled/purified water) in a one gallon stewpot over a fish fry burner. 20 minutes in the boiling water and a blow-out with compressed air left a phenomenally clean body and tiny parts as well. I reassembled per the "Honda GL1100 Gold Wing Carburetor Repair Guide" (Written by Howard Halasz, available on the Randakk site). The best $39.95 I've ever spent.

I had pulled the carb-set 3 different times and half-assed gone thru them each time, never getting it right. The last time with the Halasz book, and synchronizing per his instructions as well, and I've ridden the bike every day since (Vertical precipitation allowing).
A successful leader is someone who may be chased down the street by an angry mob but will make it look like he is leading a triumphal parade.

well here it is........put it back together to get it running and it fired right up!!! I let it run for 10 min and did a good inspection for leaks and saw nothing with a flashlight!!! rolled the bike into the garage and let it sit for a while and I cleaned up my tools and did another inspection for leaks and yip I have one on the accelerator pump.....so my question is...when I installed the accordion looking boot it has a little hole is there any sort of orientation of this little hole???

The hole in the diaphram should line up with a hole (channel) in the accelerator cap. Did you remember the O-ring also? Regards, Johnyy

Good job. Not many get to that felt ring and survive. I know I have not. I have seen pictures of the felt being replaced and lubricated. I have always been concerned that the lubrication there is lost during the cleaning process.
When you say accordion piece, I think you mean this:

If so, I have rebuilt similar carbs several times and have never concerned myself with the orientation of the hole. It seems there to protect from dirt and whatnot getting onto the shaft connected to the accelerator pump diaphragm. As for your leak, be sure to check the O-rings for the the transfer tubes if you have not already done so. Also, the pump O-ring that goes on the carb bowl can unknowingly become disoriented in the process of securing the bowl to the body and leak as a result.
