GL1000
1975-1979
SU-type all-metal slide. Removable air bleeds. No accelerator pump. Central aircut valve. Same carb family as CB450, originally sourced from Honda's N600 car. Heavy zinc content and very prone to corrosion and pulled threads. Wonderful "time machine" carbs though!
  • Ultrasonically cleaned inside and out
  • Laborious individual circuit testing
  • The best Viton sealing parts
  • Factory Honda float valves as needed
  • Checked for correct jetting
  • Off-idle hesitation removal tweak
  • Choke system and throttle linkage carefully massaged
  • Throttles carefully bench synchronized
  • Vacuum tops tested and polished
  • Manifolds inspected if included, new o-rings supplied
  • Entire assembly leak tested

$495
Plus shipping

Available options include:
  • Vapor blasting
  • Re zinc plating of linkage
  • Casting repair/replacement
  • New screws (incl Allens)
  • Thread repairs
  • Polish manifolds ($25)
GL1100
1980-1983
SU-type all-metal slide. Non-removable air bleeds. Accelerator pump. Four individual aircut valves. Same carb family as CX500, DOHC fours, CBX. A higher grade alloy than the GL1000, so less susceptible to casting issues, but a more complex carb at the same time. Really nice carbs!

GL1200
1984-1987
Stromberg type diaphragm slide. About 1/3 the weight of the GL1000 set, this is a high performance semi-downdraft carb related closely to that used on the early V4, and thus in technology and performance equal to the very best street CV carbs Keihin ever produced. Nice!

Did you know?
Each few years Honda made these carburetors smaller and smaller. Yup. The 75-76 carbs are the largest, then the 77-79 shrunk a little, the 1100 series are smaller yet, the 1200 are tiny compared with the original Wing, and the 1500 intake area is absolutely miniscule for six cylinders. This progression in increased intake airspeed follows the Wing's evolution from sportbike to unmistakable touring platform.
Shipping
Shipping insured FedEx to 48 states, Latin America and Asia. Insured USPS Priority (Air) to Alaska, Hawaii, Western and Eastern Europe and Scandinavia.
Options
Extras include replacement of broken or missing parts, welding, thread repair, bracket replating, and new screws.
Quality
I don't use kit junk. All parts are OEM, Randakk, or sourced from known high quality suppliers. If I wouldn't want it on my own bike, it doesn't go on yours.
Guarantee
My guarantee is simple: I'm not satisfied until you are. My reputation is the most valuable commodity I have, and I guard it zealously. Visit my guestbook and see for yourself.
Before you ship
First of all, realize that 90 percent of performance problems on points ignition bikes are related to the ignition. And it isn't enough to check timing, though that is important. If you haven't serviced the ignition system and/or you have Diachi points in there, you have no business trying to solve running issues with carburetor work. Take care of the basic stuff first. Once that is put to bed, along with cylinder compression, only then turn to the carbs. Drain them well, and include in a baggie any loose pieces, and remember to include the chromed linkage covers on GL1000 and GL1100 carbs as they play an important role in throttle sync. If you don't include them, sync will change when you install them later. Please advise me of any modifications to the motorcycle, type of air filter used, traditional fuel mileage, and be sure to aprise me of the specific performance issues you have been experiencing and what if anything has been done so far in response. Please include your ship-to address on a note inside the box.

Other rebuilders
There are a lot of other carburetor rebuilders out there, and some very capable ones. Naturally, each of us believes we have the most to offer. Don't choose on the basis of hype or rhetoric. Look at the customer feedback, sense the depth of background/experience (choose a rebuilder who has a powersports technician background, that is, who knows the bikes the carbs go on and didn't just one day decide to rebuild carburetors), and gauge the rebuilder's integrity. Everything else is marketing. There seems to be a little infighting, if that is the correct term, among rebuilders. I try hard to stay out of it, so please don't ask me to comment on other carburetor rebuilders.

Overseas customs issues
It's an unfortunate and frustrating situation with goods returning to Europe and Scandinavia, and their prohibitively high customs duty. I have learned that marking the box a certain way helps, and I do that whenever possible. Please don't ask me to falsify customs documents. I feel your frustration and angst over this, believe me, but my life as a Christian prevents me from taking that tack. If there is anything else I can do I am willing to do it, simply let me know.
