【KEIHIN】45. Float Chamber O-ring (Repair Parts) Review

Finally leaked after 20 years of purchase.

I have not replaced this packing for almost 20 years since I purchased the FCR Carburetor Body.

There is no seepage, so if it is Large sturdy, it is Large sturdy, and if it is Large sturdy, it is Large sturdy, and if it is Large sturdy, it is Large sturdy, and if it is Large sturdy, it is Large sturdy.
However, after 20 years, it finally leaked.
It may have shrunk because I had been draining Gasoline for a while, but when I ran Gasoline through it for the first time in 6 months, it started leaking to the point of dripping, so I had to replace it.

It is necessary to remove all the float chambers, so when replacing the float chamber gaskets, you need to use a gasoline resistant bond and stick it in the groove, otherwise the workability will be very bad.
