Feed Hole Size
2.0, 2.5, 2.8
This size is an actual measurement in millimetres of the diameter of the float valve hole and usually is stamped on the end of the seat. If converting from gravity feed fuel to pumped, down sizing this hole size eliminates the risk of seat pop off and flooding. When using with methanol select the largest size possible.
Some seats may not be found in our listings and these will only be available from the OEM motorcycle manufacturer for whom they will have been specially made.

The KV/10 O-Ring suits this float valve and numerous other Mikuni Needle & Seats.
