I don’t hear anything unusual. What is your concern, are you hearing a knocking sound? If anything (ie a bearing or big end) is worrying you you’d hear it rumbling or knocking louder with more revs. If it doesn’t get obvious then I think your engine is OK.
Thanks. The bike runs fine, matter of fact I'm back from a 2000 plus miles trip. It was the knocking sound I am not sure of but I suppose it's just the normal running sound of my tractor.
I’m guessing you’ve come from a four cylinder bike. A big v-twin is lumpier and lower reving, but gobs of torque and imho the best configuration for a road bike.
