Hi Multistrada 1000ds is back on the road & while checking rear brakes after a ride i noticed my swingarm was pretty hot, Not to hot to touch i've owned the bike for years but i have never noticed if this has happened before or is normal? any thoughts? Also i have a random misfire seems to happen when the bike is 90oc to 110oc no problem 90% of the time just rare and random. Thanks for any help.
