Sorry guys - just wanted to get a row of keywords in for those who are not electrically minded but need to know if the dreaded HES is dead or alive. From Motorworks:

https://www.motorworks.co.uk/hall-sensor-tester-toa00130-1.html

The description is a bit up sht creek as it talks about boxers, but it does appear to be for the K series. Price is a bit... those with multiple Ks will probably find it more than acceptable. Maybe. I'm not sure about that description.

It says for a 7-pin HES connector. Ks only have 5 pins.

Hence the comment about the description being up sht creek! Also it says 'uses the bike's own power supply' but I don't see a pass-through connector. As it happens, I'll be on the phone on Monday or Tuesday for some new top yoke handlebar mounting rubbers, so I'll ask.

Just been talking to Sid at Motorworks: it's a new product and he's not sure what's going on with the description so he's going to get it clarified. I noticed today that more HES testers have appeared on the website for various oilheads, so I'd guess they're trying to start a new product line.
