KZ650 Gas Cap Compatibility.

Hello KZR, I've picked up a tank from a 1979 KZ650 SR I believe and I need a gas cap for it.

I've had trouble finding the original one that looks like this:

Anyone know what other caps might fit this tank? Thanks in advance?!

Tank in question:

The fuel tank cap for the 78 KZ650 SR was 51048-1001 and it was used on the following models
Model (11):
AR50-A1 (1982)
AR80-A1 (1982)
KZ400-B1 (1978)
KZ400-B2 (1979)
KZ400-C1 (1978)
KZ440-B1 (1980)
KZ440-B2 (1981)
KZ650-D1 (SR) (1978)
KZ650-D1A (SR) (1978)
KZ650-D2 (SR) (1979)
KZ650-E1 (LTD) (1980)

there is also a gasket part# 11009-1053 the the cap uses.

Thank you, you rock!

Hi,

I am also looking for this type of gas cap. I bought a project bike from a guy and the gas cap was missing. Guy told we it was a kz650 tank from early 80's. Did my research and found a replacement cap (which I thought was 51048-1001). Long story short, gas cap came in over the weekend and it is too small. It measures about 1-1/2" diameter and my gas tank opening is 2". Which gas cap model should i be looking for? Please help.

Hi everyone, how did you solve the problem? Which fuel cap can be adapted?

The Lucas guy obviously got the wrong fuel cap & was just guessing about the part number for the one he got.
Try searching the part number on eebbaayy >> there's 1 nos fuel cap listed. Or search the models listed above plus add fuel cap to the search or gas cap or whatever other terms you can think of. Dimecitycycles has a universal fit fuel cap, but it's probably too small. you could measure your tank to see if it might fit. the dimensions for it are listed.

Exactly which year and model bike do you have that needs a gas cap? Ed

they sold me the tank as belonging to a KZ650 SR / D from 1978.
I measured the hole is about 34.7mm

Thanks for the reply. The size of the hole in my tank is about 34.7mm. Below I attach a photo sent to me by the seller.

Does your fuel tank look like the one pictured below? Ed

identical ... it's gorgeous!
but the one found has no cover on the lock ... do you have one to sell? if yes let me see it as soon as possible and give me a price before I can no longer withdraw the order ...

I do not have one to sell. I pulled that picture from the internet. Ed
