Update: Terrible Engine Clanking Noise

[Shadow Camaro]

Okay guys so I pulled the right side cover off to take a look in there. The part adidasguy said to look at was totally firm and didn't move a centimeter. I played around with everything and only the one gear in the following video moved. Let me know what you guys think. Should I open up the left side next?

My vote, time to find a replacement

IMO, there is a whole lot of things that are going to make that sound but a rod getting slapped around on the crank.

Doesn't have that ringing sound of the balancer bearing.
You might remove the valve cover and look for a cracked or loose cam journal.
Running out of gas would not cause that. Was it low on oil?
Did your friend drop or otherwise abuse the bike in any way?

Is the sound only when in neutral? You can put on the center stand and see if it goes away when in gear.


Try using a hose to your ear like a stethoscope and isolate the location of the sound as best you can.

the first video sounds like a rod bearing. i'm surprised it gets quieter with more rpm's though. could be the oil pressure is masking it at higher rpm's, and the rod bearing is worn badly enough that lower pressures aren't improving the gap.


definitely not something i would ride, or run, for any length of time. sorry man.

Completely unrelated but:

It looked like in the first video that your PAIR system is removed but no block-off plates are installed?

Worn main bearings tend to make less noise when revved and worn rod bearings tend to make more noise when revved.

One thing is for certain though, its a bearing and you wont find or be in with a chance of rectifying the problem until the engine is out and in bits

educated, ty sir!

[Shadow Camaro]

Ok so what are the chances that I can open it up and fix the bearing and be fine? Or is it more likely that the expensive parts have to replaced? Unknowing I open it up, then at the very least I'll have to replace all gaskets, seals, and rings. Can anyone give me a list of these items? Or is there a kit that comes with everything?

You are better off replacing the engine.

Spun rod bearing mean bad crank journals and rods

+1.  You can get a bike with no title, or an engine alone for $150-$200.  Swap out in a weekend, and RIDE.  A good Winter project.

[Shadow Camaro]

Where can I find an engine for cheap like that? They are all 700+ on eBay.

[jestercinti]

Post in Wanted/For sale section.  Someone has one.  Be patient, and you'll find one.

Also look on craigslist.  Remember, it can be a whole bike with no title, as long as it runs.

[weedahoe]

Yeah, you gotta be patient and keep an eye on a lot of sites. The last one I bought I paid 400 and 150 to ship from ebay.

[jestercinti]

Shadow is talking to someone now on the for-sale/wanted section of this forum.

Well I have the motor out of the bike now guys. Bout to start breaking it down to see what's up on the inside. Haynes manual will be helping me out. Also, a local guy said he would sell me his entire 2004 gs500 for $300. Says the engine works, just has carb trouble. The fairings are all busted to hell tho due to its previous owner being a drinker driver. But he says he has no time for it so he will sell it to me for what he paid the drunken driver for it so $300. I've know him for almost a year now and he seems trustworthy and he never offered to sell it to me until I told him my motor might be done for. So what do you guys think? I figure that at the very least, I could part it out and easily make that $300 back.

[bombsquad83]

Nothing to lose other than your time for $300.  You can part it out for around that if needed.

[weedahoe]

Yeah, I would buy it for 300 but if all it had were carb issues I would fix it and sell it. That's assuming the title is clear

[crzydood17]

Sell his, fix the new one.

[jestercinti]

Use his motor in place of your trashed motor.

Good winter project. Problem solved.
