Was it the front cylinder ? if so how much skin did you take off your knuckles on the radiatormark vb wrote: ↑Fri Jun 11, 2021 8:58 pm After a bit of winter fettling - new C&S, greasing shock linkage, rebuilding wheels, caliper clean-up, oil, filters etc. - it was MoT time today for my '98 Africa Twin.
Bizarrely, as I was setting off for the MoT, the front cylinder cut out, so to and from the MoT shop was on my XRV375!
Fuel was getting through to the dead cylinder, so not a carb issue. The culprit turned out to be spark plugs. Both plugs renewed in the offending cylinder and it's back to it's old self, running fine.
Yeah, it was the front cylinder. The offside plug is easy to get to, the nearside one however is a bit of a bugger. But my flexidrive plug spanner, as ever, worked a treat. It's a bit of an art not getting your knuckles scraped, but I seem to have mastered it after many years of AT ownership Whoever designed the AT certainly didn't do it with ease of maintenance access in mind!boboneleg wrote: ↑Sun Jun 13, 2021 4:21 pmWas it the front cylinder ? if so how much skin did you take off your knuckles on the radiatormark vb wrote: ↑Fri Jun 11, 2021 8:58 pm After a bit of winter fettling - new C&S, greasing shock linkage, rebuilding wheels, caliper clean-up, oil, filters etc. - it was MoT time today for my '98 Africa Twin.

Nice work anyway
It is odd. Yes, the two plugs per cylinder run off a common coil. I can only imagine one plug failed a while ago, and then the second one failed last Friday, namely when the front cylinder went dead. I (wrongly) assumed that with two plugs, one at least would be working and therefore suspected the common denominator to both plugs - the coil - had failed. But when I checked it out it was showing all the correct resistances both with and without the plug caps. And a good 12.5v was getting to the coil's low voltage winding. As a bit if a long-shot, I renewed one plug and it fired-up without hesitation. I renewed the second plug on the offending cylinder as it too must have been faulty. As a precaution, I also renewed both plugs in the other (rear) cylinder in case they were to pack up in time, too.
