carb rebuild rubber bits - alternatives

Post by Dubdenny »



Hello GWD World,

I've been waiting patiently for Randakk's Cycle Shack to get the GL1100 Carb Overhaul Master kits back in stock. Problem is every time I get an email notification saying "back in stock", by the time i get to the website they're sold out again :x

In any event, what are my alternatives if I want to stick with Viton? I've read that Harbor Freight sells Viton o-rings but I don't trust the Chinese tool store for important stuff and frankly, w/o knowing the actual dimensions of the multiple o-rings required I think it would be a nightmare trying to do it this way.

Anyway, TIA for your advice and comments

None of the HF orings are usable for the carbs

Im in the same predicament at the moment. Have my 82-gl1100 carbs open only because the fuel cross over tubes were leaking a bit but other wise the bike was running fantastic. Been waiting for the Randakks kit but it still out of stock.

It looks like I may have to find those specific O rings separately and any other bits that don't appear to be within specs as it still needs the full disassembly to go the cross over tubes.Or I may just get the generic kits and replace only what's needed and see how it goes.

partzilla shows gasket sets in stock for $43.80 each ... $43.80 x 4 = $175.20 which is somewhere close to what randakks set cost me last year.
i find myself wondering why i bothered to order from randakk rather than oem. did i succumb to a load of hype ? to be fair, their kit DOES include those TINY cotter pins and washers which are hard to find and easy to lose. i emailed them with a question which was never even acknowledged, much less answered, and others have recently been reporting problems with their customer service.

If you just need O-rings and you have the sizes (sometimes listed in the Honda parts breakdowns) you can always get them from McMaster Carr. But for a complete kit with gaskets and such I would just go with OEM.

I split the plenum today and once I disassemble all the carbs separately, I can make a list of and order OEM of what ever is needed for the full split so I don’t have to do that part again. It’s the linkages and separating the carbs to get to the cross over tubes that was intimidating and hope I can slowly work through it.

If it’s just removing the bowls and caps to clean the jets in the future that doesn’t seem to be as involved as the full split. Was happy to find the carb internals looks pretty clean and minimal crud as I had the worst experience with totally corroded carbs on a KZ400 once

Did the gasket set include everything including the air cut off valve / Accelerator pump pieces ? I saved the tiny washers and plan to use thin wires instead of the cotton pins.

the oem gasket set does not include the air cut-off valves (they are rather expensive) or the accelerator pump diaphrams (no longer available from honda).

by the way, there is an air-cut-off valve delete method. i have never done it but i heard about it from a reliable source. a google search should turn it up if you are interested.

After examining all the parts, the air cut off diaphragms were the only ones that were almost about to shred at the edges so they have to be replaced. Due to unavailability of the Randall’s kit , I would like to split the project in 2 parts. First ,replace all parts that require the full split with OEM as Honda carries the air cut off diaphragms. The parts that dont require the full split can be OEM or aftermarket as it doesn’t seem to be complicated to dive in to the carbs when the full disassembly is not needed.
