Engine Noise
12/01/13 at 15:59:30

Perhaps someone can point me in the right direction. Their is a faint clicking noise that sounds like it is coming from the top left of the engine when sitting on the bike. It becomes more apparent when the rpms are between 2500 - 4500 (I'm just guessing). At first I thought it was the cam chain but, my understanding is that shouldn't be a concern till 12K miles. It runs strong; although, if it is something I can correct before any serious damage occurs I surely would. Any advice would be appreciated. Best regards.

Noooo.... Harbor Freight sells them for less than $5...
It's just like a doctors stethoscope but without the flat bit on the end...
You just put the end of the tube at different paces and try to find the noise source... (I took the end stick bit off, and just use the chrome tube part.. seems to work better for me)...
... you can also just put your ear to the handle end of a long screwdriver and touch the tip at different places (just can't do corners very well)...

...(cam-chain is on the right side... and the sound is usually in the lower case)......but sound location can be tricky...
Your noise sounds more like valves at upper left of engine... Are they adjusted?...

A piece of rubber tubing will also work.....just not as fancy. Put one end up to your ear...the other is poked around the areas you think the noise is coming from.

Common rattles on the Savage are the speedometer and the headlight.

From the area you are describing....it might be the compression release touching the exhaust rocker arm. Maybe the springs is broken or the cable is too tight. Or it could be a loose spark plug.

I went and picked up a the mechanic stethoscope and it is amazing what you can hear. When sitting on the bike it is definitely on the top left of the head. I'm guessing it has to do with the cam shaft in some capacity?

Assuming so, I suppose it would be a good time to replace that as well as anything else. The cam timing chain sounded a little loose, not excessive; although, the 12 K inspection sounds spot on. If you have any thoughts that would be greatly appreciated. Thanks and best regards.

If there are rough or flat spots there....most likely it was from using an oil that does not have sufficient ZDDP.

I'm guessing this would be an ideal time to do the Versey tensioner. What else should I consider? Thanks again.

Re: Engine Noise Reply #10 - 12/02/13 at 09:09:44 Push the compression release arm to Home,, make sure the spring has it all the way back. I like a stethoscope with a hose for homing in on where a noise is coming from, then I stick a rod in it to listen to see what kind of internal clicking/clacking/squeeling noises are coming out.

pg Serious Thumper Offline Posts: 5273 In Transit	Re: Engine Noise Reply #13 - 12/02/13 at 11:38:59 I'm going to do a bit of research; although, I guessing Dave is probably correct. Is it going to sound a little rough for 5K then seize.? What do you think? What a the general scenarios? Thanks.

Try the compression release first as JOG2 suggested.

Then make sure the spark plug is not loose.

Then take the valve adjustment cover off and see if you can see anything inside that makes you think the cam or lifters are worn. There is a post a long time ago where the fellows rocker arms were just about worn completely through......no idea how to find that old thread and I can't rememember who posted it.
