I found these online and I think they may be an alternative for the fuel injection relay. Can anybody confirm the wiring configuration is correct.https://www.aliexpress.com/item/4000545650948.html?spm=a2g0o.productlist.0.0.13293af13yBjBO&s=p&ad_pvid=2020032300480912250372252879900000246618_1&algo_pvid=9f2ab320-d775-4012-af43-e786c06084f9&algo_expid=9f2ab320-d775-4012-af43-e786c06084f9-0&btsid=0ab6f83115849496898153239e1049&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_

By the look of the picture, the power goes to 87 or 87a,  but bricks need power to both 87 pins at the same time.

I've bought a cheap starter relay from aliexpress a while back just to see what they were like. It was really really poor quality. At US$7.50 for 5 relays, you can bet they will be cheap quality and probably unreliable.
You can get a FI relay from Motorworks for about AU$25 +frt

Sorry Martin - that's a boggostandard changeover relay. Nothing to stop you using one; you just need to attach both green/red wires to pin 87. There's also a further problem in that the K relays are DIN 1 Type A standard i.e. pins 30 and 86 are reversed compared to DIN 2, so just about none of the modern relays are a drop fit.

If you (or anyone here) is worried about getting stranded with a knackered relay, just remember that. Unscrew the relay block, push out terminals 30 and 86, reverse them and drop in a modern relay. For the FI what you need is a Type B switching relay.

If you're not sure what you're looking at, check the pin numbering. If there's a pin 87a then it's a changeover relay. If there's a pin 87b, it's an FI-type relay. If there are two pin 87 (no suffix) then both outputs are permanently connected together. A better idea IMO is to pre-empt any possible problem by doing the pin swap now and dropping in a set of modern relays.

As Hollister says, Chinese relays are crap. I have a suspicion that a lot of the cheap Chinese relays are ones that have failed their QA checks but have somehow managed to find the back door.

The factory relays are very very reliable and proven over time.

The one exception might be the low battery starter relay issue.

Thanks fellas I won't be going down that track. Boredom set in and I wandered off track.

far simpler than that dai ..the contacts are under rated by what appears to me a factor of 3x and just poor manufacture metallurgy standards , impurities are rife in almost anything from there  I have stories just about copper cables that would water the eyes of an lucas officianardo

Dammit Charlie - Even Joseph Lucas, "The Prince of Darkness" would reject such relays...although my first Ducati (a very early 860) had the most diabolical Italian wiring - crap insulation over terrible copper wire that oxidised due to impurities and oxygen contamination...and lets not talk about the electronics and switchgear...oh I could go on.

They always quote inrush current and not steady state. A 40A Chinese relay is probably only safe for 10A steady state - if it works at all for very long.

lol
then you could imagine my old duke   a mid 60s single ...  enough said

My personal choice would be getting a European relay, I had a 1999 Suzuki burg an and the ice failed, I bought one from Belgium that had European components and it was a lot more stable.
