You most likely won't find the tools at any auto parts store.

The tools include a flywheel holder that I built, a puller, and a large deep socket.  The tools can be rented for $ 15 - but you will have to pay shipping both ways, and provide a $ 150 deposit until I get the tools back without damage.

You don't have to drain the oil, if you can lean the bike over to the right side....I put a piece of carpet on the floor, and rest the handlebars on a stool. You might want to buy  magneto case gasket just in case you tear the original.

NOTE:  I need to post a sticky about the tools being available.  At this point I "own" the tools....as I paid for them.  The original idea was that members could donate $ 20 and get a lifetime subscription for the loan of the tools - they would only be responsible for the shipping and deposit.  Or a $ 15 fee if you only needed them once.

I can't guarantee that your flywheel is loose - we only have 2 documented cases of a loose flywheel.

I am still so puzzled as to why the header is leaking from where the bracket hold it into the block.... I replaced the gasket and made sure the bracket is on in the right position... Any ideas?

Are you sure you removed the old header4 gasket before putting the new one in?  Sometimes those old gaskets are so black with carbon it is easy to mistake it for part of the head.

A leaky exhaust might sound a bit like a knock?

Have you checked your valve clearance?  If it is off by more than a thousandth or two (loose)....then maybe you are getting some serious cam/rocker wear and that is the source of the noise.  On the last 4 cylinder heads I have worked on - only one cam/rocker assembly was in good condition, and the other 3 had severe wear on the rockers and cam lobes - and one bike only had 3,800 miles on it.  (This is why we recommend using Rotella T so strongly).

Interesting point about the old gasket. It was basically shot. I assumed I got all of it out but I didn't do a very thorough check. I will go back in there before doing anything else. What's the best way to pull out the old gasket? Pop it out with a screwdriver?

Here is a poorly executed video of the engine noise. I will try and take a better one once I replace the battery (most likely will be on Wednesday). At that time I will also quadruple check the header and exhaust system.

Note: I bought the bike with a drag exhaust from Blue Collar Bobbers.

Should I warm the bike up first? Or is it okay to do this fresh after starting?

"Do you hear the noise when it's cold and warmed up? If so it doesn't matter."

Makes sense! haha.

Luckily my girlfriend is in medical school so I can use her stethoscope to really isolate the noise! Should have it fully inspected by the end of the weekend or as early as tomorrow!

I will post a pic with a circle around the area. Looking forward to what everyone thinks!

I have a feeling it has something to do with valve clearance, but who knows.... (Luckily if that is the case there is TONS of info here to walk me through the process!)
