Just picked up a used 08 Trail Boss for my son.
Brother picked it up, so i did not get to hear it run till it got home.
Has a noticable engine knock at idle/low rpms. Seems to go away at about 1500-1800 rpms.
Runs great!
Motor has about 30 hrs, and had original oil in it. I changed the oil next day, along with spark plug, oil filter, and gear lube.
Called previous owner, and he says he was told it is a normal noise for it.
Talked to 2 Polaris dealers, and both say it's a common noise. "Nature of the beast". Was todl that some make more noise than others.
Took it to one of those dealers yesterday, and he litened to it, and says not to worry, it's common for Polaris.
I've owned Honda, kawasaki & yamaha, and never had a noise (knock) come from the engine like this
Anyone have a Trail Boss 330, and what your's sound like? Is this noise "normal".

Thanks in advance,

Jeff
