Frequently Asked Questions

What carbs does this O-ring fit?

Mikuni HSR42, HSR45, and HSR48 carburetors found on Harley and Indian engines.

Why would I need to replace the float bowl O-ring?

Over time the seal hardens and shrinks, causing fuel to seep from the carburetor base. A new O-ring stops the leak.

Is this a genuine Mikuni part?

Yes — this is the genuine Mikuni OEM part number F616-94028, not an aftermarket copy.

Do I need any special tools to install it?

No special tools required. Remove the float bowl, swap the old O-ring for the new one, and reinstall — a 10-minute job.
