I had the carb vapour cleaned, all new jets and vacuum sliders. Next step was to replace the complete ignition system, including new, genuine plug caps. The cdi was a ...

Sounds like progress

Glad it's sorted

Thanks charliext1vj,

I have the Fowlers app, what a waste of time that is as it doesn't list the plug caps. I got a pair from CMS in the Netherlands, arrived in two days - 124 euro for the pair delivered. Bike now runs fine.

Fantastic, well done.

Thanks for the link, unfortunately, no spark plug caps for the Super Tenere.

Does anyone know of any suitable spark plug caps to replace the originals, I'm having trouble finding a pair of genuine caps in the UK. Is there a suitable alternative...TDM maybe?

Thanks, I've taken a look at my vacuum hoses and they seem fine, be keen to hear what else you may find.

I'm located in South Wales.

Ah, ok, I'm in the East Riding of Yorkshire. Unfortunately I don't have a garage to work in, I need a decent day to wheel the bike out of the shed to take a look.

Thanks for the pointers though.

Nick,

I have exactly the same problem as you, and have been scratching my head for a while now trying to sort it. Where are you located?
