Hey everyone, my dad has a 1700 Vaquero with about 1350 miles on it. One thing I've noticed is that at idle, cold or hot, doesn't matter if you give the throttle a good bip and raise the RPM's up to about 2500, and I'm not talking about raising the RPM's gradually at idle to 2500rpm, just a quick blip of the throttle, there will be a clunk, and it's fairly loud. The bike runs fine, with no issues, but I'm just really curious to know if this is a normal noise for the 1700 engine or if it needs to be checked out?

There should be no clunking sounds just a smooth bark from the exhaust.There may be a loose engine bolt somewhere. I would have them check the upper mount first. My VAQ makes no such noise.

Are you talking about a back-fire? A loud cluck sound doesn't sound right to me, but a back-fire, absolutely...which is usually caused by unspent fuel sparking in the exhaust.
