Topic: Float Height

[rchrdms]

Hi,

I'm rebuilding my carbs and the manual lists a bunch of different float heights for my model(1972 CL 350 Twin).

My engine number is CL350E-4040351. This number is not on the chart. The float heights are 19mm, 21mm, and 26mm, depending on engine number.

I have twin Keihin 722A carburetor.

The engine numbers listed are 1055165 to 1065278 (21mm);

1065279(26mm);

and prior to 1045165 (19mm).

Thanks.

I would probably check your engine #s again and see if your  4 could possibly be a 1. Some old bikes can have some corrosion there making it hard to see.

I might be able to help, here is what I came up with:


CL350K4
Sell Date: 1972-73
Rel Date: 02/01/72
Product Code: 345 (Middle number of Honda part numbers)
Frame number: CL350-4000001
Engine number: CL350E-4000001

So the engine number does match up as a `72 K4 model.

NGK: B 8ES/ ND: W24ES Gap .028-.032in
