Kei Hin Carbs

[biggyfries]

I was wondering when someone would mention Randakk's video--I bought the kit and the video and did my own rebuild and when it went on and the fuel went in and it fired up like a new bike--and it ran PERFECTLY for about a day. I was puzzled, but I found out what the problem was--I hadn't cleaned the plenum orfices adquately, and I had no tiny wire screens at the main needle/seat. There was a bit of junk in the fuel tubes or orfices. I finally got the entire thing clean as it says in the vid, and it runs like a champ--PERFECT again. Its like anything else in life--you do your best and still things can go wrong, but eventually you win in the end and I am now something of an expert on these GL1000 carbs. When they are right they are PERFECT! The video reveals everything. Don't skip any steps!

I can remove carbs in unbelievably short time now that I'm all practised up. I should time myself some day. It will be just a few minutes. I invented a little wire hook that speeds the installation of throttle cables, and a special claw foot wrench to tighten the throttle adjuster nuts--it is easy when you're all 'practised up' as I am. When everything is spotlessly clean and all the threads are new or perfect--it just zips apart or back together. Nice.

could you post pics of your special tools. I can almost see them in my minds eye but a photo speaks a thousand words.

I have a nice long finish nail with a short 90 degree bend at the end, I clamp that in a pair of small vice grips and that is what I use to assist routing the cables onto the bellcrank.

I have a set of forceps that I use for hooking the cables.

once they work they work but Mikuni's are alot easier and more reliable, Have a set from Yamaha Venture I am going to get to fit my 77.

I use a piece of coat hanger with a short 90 on one end the other end has a longer 90 for leverage.

I realize this is an old post but am presently preparing to reassemble using a Randakk kit. As the original owner, I know these carbs have not been molested until now. The carbs were literally glued shut with varnish from evaporated fuel from the idiot PO not pickling them before "I" stashed the bike in 87. All parts were "crock pot" boiled, followed by an ultrasonic treatment, followed by compressed air. I've watched Randakk's DVD at least 3 times just to make me more familiar with the process. I'm finally feeling confident enough to reassemble these bad boys, so I give them one last "look over". I didn't feel warm and fuzzy with the looks of the "brass". I bought some carb cleaner and not not only shot the brass but soaked same in the cleaner. I couldn't believe how much additional particulate fell out of and off off the internals. The next couple of days will tell the tale. If after all is said and done, I end up having to remove them from the bike to address an issue, I feel confident I will be able to diagnose and correct same. Here's one pic of one bowl when I first disassembled them. They were all this bad or worse.

PO's can be such a pain!

[Dog Boy]

Hahaha! Yep, they can be real jerks!

I'm glad this thread got revived. I missed it the first time around and that first post is a hoot to read.

My direct experience with an 83; Bike has never been stored longer than 3 months since new. Carbs have never been off - annual synch and Seafoam has been the only maintenance. 96k on stock carb setup.

I was going to ask him to send me the carbs insted of smashing them, guess I am to late buy now.

I can certainly feel the original poster's frustration. I'm battling with the carbs on my 82. I've had them out at least 4 times, now. PO had been through them, as well. I still don't think mine are quite right, yet, either, so maybe fifth time is a charm?

I had the video and kit when I did the rack on my 77. I almost wore out the DVD...That set went back in, and was good to go. I went back later for the off-idle fix, as outlined in the DVD. That went fine, too.
This 82 has been fighting me from the start! It gets frustrating, and sometimes seems like NOTHING works right.
There have been thousands of them made, and repaired, I know.....That doesn't make me feel any better about THIS one, though. I hope the original poster got his carbs sorted out.

I've almost completed a rebuild of a pair of Mikuni 34mm carbs from an '81 Yamaha XS650. These carbs are simple, durable and pretty easy to understand. It's hard for me to understand why the GoldWings carbs would have had to be designed as complex as they are, other than maybe squeezing out every possible bit of HP for the engine.

Honda Civics made in the late 80's and very early 90's have carburetors so complicated that even Honda service techs won't work on them. Technology vs simplicity. Oh well.
