I am considering a tuned 1100GS currently for sale on EBay, yellow one based in Esher Surrey. Has anyone tuned / chipped their 1100 and found it to have a negative impact on reliability or longevity of the engine. I'm in no hurry to buy so happy to walk away and wait for a standard one if that's the general opinion. Any thoughts / advice would be gratefully received.
Thanks
Mark
