Power Lost Power Drop 2022 Thruxton Rs

Well if I were you I would put the new battery on (assuming it is fully charged) seeing as you have one there.
Bad fuel could well be the issue, the stp treatment shouldn't do any harm. I don't know what octane fuel I use but I only use E5, never E10 in my T509.

 

Shame E5 will be phased out in 2026.


Edited to show correct information/ newspaper rumours, fuel type changed from E10 to E5.

 

Did you mean E5?

EDIT - I’m confused (it doesn’t take much) I was asking a question as a ban of E10 sounds less likely than a ban of E5, but the disagree makes me think I’ve got completely the wrong end of the stick. Anyone cast any light on the situation for a numbnut like me? Thanks

 

Have you checked the fuel line from the tank isn’t kinked?

 

I had a similar problem with my Speed Twin 1200, virtually the same engine as the Thruxton. A new battery cured it, no problems since then. I use E5 petrol whenever possible, and avoid supermarket pish unless it's Tesco E5. In the UK E5 is either 97 or 99 RON, depending on which brand you buy.

 

Hi not sure if you resolved thus issue but on my 2020 Thruxton RS i had a similar problem when starting, engine would turn briefly not fire and reset the clock… second attempt it would fire up. Problem was the earth point, just follow the negative lead to the mounting point on the back of the engine and clean the contact. From memory 10mm socket is needed ans emery paper to scuff up the contact surface. Job done.
