CARBURETOR CLEANING, REBUILDING & JETTING

Professional, meticulous & thorough is how we rebuild certain vintage motorcycle carburetors from the 1960s, 70s & 80s.
Below are several examples of the variety & scope of 
carburetors we've worked on.  Also, a common 
petcock/fuel valve issue is explained - please see below.  
* We only rebuild vintage street bike carbs
* We do not bore carburetors
* We do not sell carburetors

aluminum, rotten fuel & moisture.

AFTER:  A thorough cleaning, re-finishing, and new parts are what we call a "Carburetor Rebuild".
INSTALLED:  What a lovely rebuilt Amal 636. 
Pity the customer requested we reuse, as is, the intake manifold instead of cleaning.

Here we are correcting a home mechanic's attempt at rebuilding the carbs from his 1981 Honda GL500 Silverwing.  
To save money & time, it really pays to have a professional do the work.  Plus, while we had the bike in our shop, we found hidden under the side cover 3 tiny bubbles under the paint on his fuel tank.  These are the beginning signs of rust.  The owner didn't notice them when he removed the carbs only 1 month earlier.
Note the double gaskets    
 Different needle valves - 1 was homemade

Randy is seen here correcting the carb work done by the owner of a 1977 Honda GL1000 Goldwing. The problems we found were inconsistent float levels, a torn o-ring (intake manifold seal), plugged primary & secondary air jets, and debris that was found in one of the carbs.  Replacement of a damaged needle, 4 kidney-shaped gaskets & the intake manifold seal were required along with a proper, professional carburetor rebuild.

Here's an example of why we don't purchase or use "cheap" petcocks/fuel valves.  Cheap ones use a rubber sleeve/seal on the inside.  When the sleeve comes in contact with Ethanol gasoline, it swells.  See picture 1.  

In picture 2, the swollen sleeve is on the left while a new, UK made petcock is on the right.  Instead of low-quality rubber, the UK petcocks use a nylon or metal sleeve that's doesn't suffer the same problems as the rubber sleeves.

What we do when we re-build a carburetor
  • Total disassembly of the carburetor
  • Complete & thorough inner & outer cleaning the carburetor body & all parts
  • Provide correct, quality aftermarket or OEM rebuild parts as a kit or purchased individually from manufacture
  • Perform repairs such as milling carburetor bowls or bodies & float repair.  (Additional charge of .25 hour labor.  Labor = $90 hr.)
  • Bench test the carburetor for leaks
  • Photos of the rebuild emailed to you showing the before, during, and after 

NOTE: final tuning of the carburetor is the responsibility of the customer.  We bench test but fine tuning can only be done once the carburetor is on the bike.

This is what can happen to a petcock's rubber seal when it's been subjected to 10% ethanol gasoline for only 2 weeks.
  
On the British bikes we service or restore, we ONLY use UK petcocks that do not use rubber parts.
