Radiator cap fitment

[MrFeo]

Had shop do my coolant since I was taking it in for a look after purchase. Noticed expansion reservoir was below the min 2 weeks later. Hoping they foolishly didn't fill enough and not leaking into oil. (no signs of leak on ground, I need to check the oil (I just changed month ago) itself but lack of dip stick hurts the cause).

Anyway. Topped it up and noticed radiator cap looked like funny fitment to my untrained eye. Is this typical? I only took apart the 2 front small plastic pieces to get expansion reservoir. Not the full fairings.

Yes, that’s pretty much how they look; they usually look like they’ve been fitted on askew 

It’s just that the cap is horizontal, while the radiator is tilted forward.

Blimey. An XS400 - that’s a blast from the past! Is it silver? Or, possibly, blue?

Exactly - thanks! Thing looked slightly cockeyed. Almost back to the right, but not severe. Also goofy is has another notch in the pipe right below the cap, as if the cap were meant to go down further and rest on it. thanks for confirming - just wanted to make sure it wasn't a half ass job by the shop setting me up for trouble down the road.

XS400 Special II (the special had drum brakes, not disc... special indeed haha) - it's blue. It is awaiting a R/R rewiring (apparently crappy wire doesn't last 40 yrs) and carb re-recleaning and balancing. fun little thing to bolt around town if I find the time to get it back on the road

That cap doesn't look like it's closed correctly.

I'll try to monkey with it, may require also taking off the side panel. That could explain the reason it was low on fluid...

Going to let the shop know... and probably stop taking it there i guess 

I wanted to get a more modern bike so i could trust a shop with some of the more involved work (i know, fluids aren't the most involved). If putting on a radiator cap is challenging for them, doesn't inspire confidence. Luckily got another 2 years of just changing oil. And some TLC for the wishbone suspension. And the bobbins

Thought I saw, somewhere here, that the rad cap needs replacing simply because of gasket wear or deterioration.

Anyone have the part # for the radiator cap?
I'm sure its on this site somewhere but, a search didn't turn it up. Nor did a search at BB. List the cap as #2 but no part #!
