I have a bit of front wheel 'bounce' on my new 1250 GS (with ESA) with cast wheels which has me scratching my head. I have Wunderlich bar risers / backs on there and have rotated the bars down slightly closer to me. Could this have upset the front end handling (i.e. not enough weight on the front end)? I had them on my 2017 GS TE and they were fine. I've tried the ESA on all settings. Makes no difference. Will be having it's first service next week, but wondered if anyone has experienced this? Obviously, tyres etc are all good as it's only done 500 miles. Tyres are the Bridgestone A41s and I'm running the correct 42 / 36 psi (2.9 / 2.5 bar). I also have one of those ram mount bolts in one of the handlebar clamps. Many thanks.
