Carburetor Clean & Rebuild

Keeping the carburetors balanced and clean on these bikes is one of the most important steps in making sure they run correctly. The carbs were dismantled and cleaned with Threebond engine conditioner, then new Litetek seals installed to replace the old original seals. A quick bench balance was done after reassembly, though it will need a proper vacuum balance when the bike is up and running. In the near future the rubber carb boots will be replaced but they are in OK condition as is.

Current main jets are:
(1)  -  (2)  -  (3)  -  (4)
118 - 115  - 115  - 118


PROCESS


Original condition once off the bike
Soaking and brushing dirt away
Carbs pulled apart and cleaning again
Carb bodies cleaned
Carbs completely disassembled
Carb bodies ready to be reassembled again with Litetek seals (Note: some seals are not on their correct parts, this was changed after the photo was taken)
Final check of galleries before main/pilot jets are installed

Refitted to the engine
