I meant to update the story of my cheap Chinese radiator ages ago but time, enthusiasm and access to the photos took a while to coincide.
The upshot is that it was a pain to fit.
At the bottom left hand end of the rads, the main inlet port on the original is angled back… the steel pipe that the short length of hose connects to is similarly angled so the hose has a straight run.
The new rad was made with the port in line with the main axis of the body. This means the hose has to make a slight Z bend to fit, but the diameter and thickness of the hose is too great to make that possible without putting a lot of strain on the fragile alloy radiator.
It was the same problem at the other end of the radiator (sorry, didn't take a comparison shot of that), with the thin pipe arranged in line rather than angled back.
Rather than face the hassle of sending the item back to Hong Kong, I decided to modify the fittings on the bike to make them suit the radiator.
On the right, I bent the mounting brackets of the thin steel pipe so that the narrow hose was parallel with the connector on the radiator.
Then I found some longer bolts and assorted spacers (arrowed) to mount the steel pipe forward enough to get the hose in line with the rad connector.
I couldn't manage the same trick on the left quite so easily. The top mounting bracket on the big steel pipe fouls the radiator when it's mounted far enough forward to give the hose a straight run.
So I cut it off.
Here's a side view: top arrow indicating the unsupported end of the pipe and the lower arrow indicates the spacer on the remaining (bent) mounting bracket.
I was a bit concerned about having the pipe unsupported at one end, but the bottom bracket holds it firmly and vibration doesn't seem to be an issue. It's been ok for the couple of thousand miles I've covered since doing this bodge anyway.
