it;

I have about 400 miles on my 2017 RC 390 and the chain is very loose and lower part of the chain touches swingarm if I move it; it was like this from the day one. Is it normal, if not how much slack it should have?

Okay my name is Gary and I’m bashful so I will make this short and to the point... I’m old 74 to be exact, been riding since I was 24. I currently have three bikes a 2011 BMW S1000RR with 90,000+ miles on it; a 2015 KTM 350 EXC-F and a three week old (purchased new) RC 390 with 1,118 miles on...
