Upgrades
Upgrades are options for going beyond the thorough, basic carb rebuild. Some rebuilders claim to offer more by including many of these things as standard, but actually cut corners in the basic rebuild in order to provide the extras at no additional cost. There really is "no free lunch."

Unexpected expenses
Sometimes missing or broken parts become evident during a rebuild. I include a number of unexpected repairs and services in my rebuilds even though not all carbs need them. Thread repair and float bowl repair are examples. Even some unexpected parts, such as the bowl vent tees. However, slides, tops, throttle plates, float bowls, floats, castings, jets--these are expensive parts that are rarely needed.

Quality
I don't use commonly-available kit parts in CBX carbs because they are junk. This includes Dynojet kits, which are next to useless on the CBX carburetor. If I wouldn't put it on my carburetor, it doesn't go onto yours.

Guarantee
My guarantee is simple. I am not satisfied until you are. No matter what the issue, I will stick it out with you until it is resolved. I am blessed to be able to say very few times has a significant oversight emerged.

Please read
First things first. Avoid assuming that the trouble you're having is neccessarily carburetor related. After measuring cylinder compression, ignition timing and spark strength (using a special opened up spark plug), and ensuring good fuel flow through fuel tank and petcock, confirm the final diagnosis with the t-shirt test. Loosely wrap a t-shirt around your air filter element as a test. If the engine runs better, then carburetion is indicated as a problem. If no change or worse, repeat the test with neither t-shirt nor air filter element. Improvement in either case indicates carburetion. No improvmenet in either case mostly exonerates your carburetors as the trouble. When ready to send me your carbs for shipping, be sure to drain them well before packing, include in a baggie any loose pieces. Be especially careful with the float bowl overflow hoses, they are the most delicate parts during shipping. In fact it's best actually to remove them. Please advise me of any modifications on the motorcycle, the type of air filter used, what you have been getting for fuel mileage, and be sure to aprise me of any peformance issues you have been experiencing and what if anything has been done in response.
