Radiator Cap Dimensions/X-ref

[SPOONDIDDLY]

G'day guys,

I'm looking to do an overhaul on my RVF's cooling system - inspecting, cleaning and replacing everything.

So I have started to stockpile bits for this and the one thing that I am unsure of is the radiator cap!

Does anybody know any aftermarket brand part numbers for radiator caps that will work?
Or the dimensions/specs for what is needed?

I would prefer to go aftermarket than OE as I work in automotive and can easily access parts locally

[SPOONDIDDLY]

So nobody has an alternate part number or a spare cap that they could measure up?

If I have the correct measurements I can find a suitable part number and post the x-ref for all

[SPOONDIDDLY]

So I take it that no NC30/35 owners have radiator caps?

Hi.i have a cap to hand.what do you need know chap?

[SPOONDIDDLY]

Brilliant!

I guess I need to know:
- diameter of the main seal
- length from the top of the cap to bottom seal
- Inside diameter of the radiator cap (not including the toggles that hold it on)
- Distance between the toggles
- Pressure that the caps rated to (if it's printed on the top)
