Did you get a look at the inner cam chain?

Well the cam still looks properly timed, you can see the mark at the 3 o'clockish position.

I'd put it back together and fire it up, then take it for a ride if it doesn't sound ugly.

Because you did not do a compression test prior to taking it apart you can still check to see if the piston's, rings and valves are ok. First crank your motor by hand with the crankshaft nut with the plugs out just to make sure nothing is binding. If every thing feels pretty smooth then bring your front cylinder up to tdc so both valves are closed and put air to the cylinder through the spark plug hole and listen if air is escaping any where. If you bent a valve or anything, you will here air escaping out the exhaust or back through the intake, make sure you remove your air cleaner. You will also need to pull the oil fill plug to make sure nothing is coming back through the rings or possible a burnt piston... This should eliminate any serious broken issue. Good luck man....

I wish you had a video to help us help you......

Well dudes....I think those who said it was the compensator are right.

I bought one of those Vulcan compensator eliminator sprockets and threw it on tonight. I left the outter primary off.

See the video at the link below:

I no longer hear what previously sounded like something broken rattling around in the engine. The clutch made some noise but I'm guessing it was normal and would be well dampened once it's enclosed in the primary with oil around it.

I'm feeling confident that it was the compensator. You guys let me know otherwise.

Now I have to decide how I want to fix it. From what I've read about these comp eliminator gears, most are afraid they will do damage to the engine/tranny.

I've read some good stuff about this Baker comp:

I guess the Baker comp is the way to go?

Yeah..when I get home I can post a picture. However, the only thing I saw was that the ramps were shiny. There were no broken teeth on the sprocket or broke/galled gear splines. All the springs looked good. The whole thing has me puzzled.

I picked up the Vulcan sprocket for peanuts just to help diagnose the problem. I really didn't intend on leaving it on because I've read a lot of stuff that makes me think it might do some damage to the engine/tranny over time. I was hoping to read/hear some more about comps versus the comp eliminating gear.
