Hi and happy Xmas everyone, I'm going to treat the 400F to a set of new spark plugs, caps & HT leads - not as straightforward as I imagined! I've read several posts about plug types, 'R' plugs, resistor caps, don't mix them, etc, but I can't track down an accepted best solution - is there one please? I notice DS stocks only NGK DR8ESL 'R' plugs, but 2 types of NGK caps - are they all compatible?Also I've never had to make HT leads before (1st bike project, it's a lot easier with cars!) - the coils on the bike have what I would call a male conductor fitting: (Attachment Link) but so does all the HT cable I can find for sale, eg: (Attachment Link) Again, are they compatible? Is there a thread that covers best practice for making leads please?Apologies for the newbie questions! Darren.
Back to original post... those HT leads aren't male connectors, that's the copper wire left sticking out. Cut the HT lead straight across the end and then screw it into the coil fitting. The coil screw should line up with the copper core to make the connection.Just out of interest, how old are you Darren? 🤔

Just wondered. That fitting was pretty standard in 60s and 70s on British cars and bikes with Lucas type coils.

I got the correct plugs and caps from here: (Attachment Link) https://www.gsparkplug.com/ignition/spark-plugsThere are two different pattern plug-caps used, 2 90° and two at about 45°
To my experience, the straight caps work better for Cyl 2 and 3. I get a weird bend in the plugwire when using an angled cap.Those are SD05F (instead of the XD05F).Cyl 1 and 4 take the VD05F.
