Hello again so if you don't know the story is I bougt a 2000 savage for $500 got it home and it was seized as in melted metal stuck in the spark plug and all in the engine.
So I ordered a 1998 engine with 1,500 miles (according to the seller)for $530 on eBay and they shipped it the whole way upside down. A few top price were broken so I replaced them from the other blown engine. Like the valve check cover and one other thing. Anyway I started it right up no issues other than backfire.
I did line up the valve timing and what not anyway to make a long story short there is an engine knock that happens when I give the bike throttle in the engine top end near the exhaust manifold. It is a definite knock. So I'm pretty worried.
I had to sell my chopper because of money issues and really needed a bike and found this one and between the bike, the engine, parts, tools and getting it on the road it was a little over $1400 not to bad but I want it to last and would like to enjoy it.
The knocking can be pretty faint and really comes and goes with throttle but again I want the bike to last

yea, try to record a video as the valves sometimes tick a bit loud...

BTW. Good luck with the bike!

I think we need the long story.
so hard to diagnose something you can't see.
you timed it... so you had the cam chain off?
what else did you do?

check your charging voltage.
if it wasn't charging, a weak battery will cause poor running.

mine is very quiet, no mechanical noises coming from the engine.. just a slight ticking of the valves

I bought some pretty inexpensive oil and I am starting to think that is my issue have you guys ever heard of Brad Penn V2 4-Stroke High Performance Motorcycle Oil "The Green Oil" ?
I'm thinking I empty this cheap nuts out and get some Royal Purple and I bet that metal knocking stops.....

Anyway here is a video although it really doesnt do much good but if you have normal bike like the one in the previous post and this one playing at the same time and you pause one you can really tell the difference mine sounds like it has old used up oil in it.

Yep, I watched the video too and it sounds pretty normal to me. I had a "Frankenstein" with a 1987 motor in a 2005 frame. It sounded pretty much like yours. I have a new 2007 with 2,000 miles and it sounds like the previous video posted by someone. As a new Savage owner with no other real recent 4 stroke bike experience (my last bike was a 2 stroke Yamaha road racer in 1971) I don't have a frame of reference, they just seem to be a noisy motor. On the video you said it had 15,000 miles but I thought you mentioned it had 1,500.  If it has 15,000 I'd be sure to check out the cam chain tensioner before riding it seriously if you haven't already.  I checked my '87 and it was JUST about ready to fall out and the previous owner said it had about 9K.  Good luck with the project. Once you get it up and going you're going to love this bike! Hang in there!

get a mechanics stethoscope, you don't hear it in there it's not a problem.
