Looking at a 1500 to buy but has knock in engine?

Thanks, we warmed it pretty good and checked the oil. It does get louder under acceleration. By using a yard stick to the ear method we determined the knock was coming from behind a cover on the right lower side of the engine. I am sure it is not an octane knock.

Vulcan engines can be a bit loud especially when cold. Knocking can come from a lot of things.

Do yourself a favor and find ANY 1500/1600 Vulcan and listen to it to determine if the knock is out of line with a known good engine. Make sure the engine is warmed up and has they both are using the same octane fuel as well. Most Drifter run better with premium fuel. I won't cite octane numbers, there is a long story to octane requirements.

I found a 1500 I am interested in but while running there is a knock in the lower part of the engine. Is there any thing in the trans or clutch that knock,,,is there any history of low end problems with this bike?
Thanks,
