My RS has always had a lumpy idle, fluctuating and never steady. I also notice that when pulling away gently it stutters then suddenly it will surge. It almost feels like it’s a fuelling problem. I did take it into triumph for the idle issue, who thought it may be an air leak and they tinkered with it but it is still doing it. I can kind of live with the idle but I was wondering if a remap from Hilltop would fix the stutter when pulling away?
I would give Triumph another chance to sort it first, but if it’s been like this from new and they can’t do it. Take it to Hilltop and ask for remuneration if they sort it out
I’d be wary of going to Hilltop as there’s been a lot of negative press about them recently https://www.thetriumphforum.com/threads/hilltop-vs-other-dyno.17160/page-2
