Is it possable on these things to have a bad injector load a cylinder up with fuel so when you crank it over it will almost hydraulic and give that bang and sudden stop? Just a thought.

(You really mean "piston" and not the "Head",,I am guessing)
I want to lean more toward what Breeze said about a weak compensator. I swapped out my comp for a SE comp on my 2009 bike and a lot of noises did go away. The removed factory comp was like BRAND NEW (6K miles) so installing a New factory comp would Not have cured my noise issues.
You also may want to perform the "primary chain tension adjuster" trick. It just may help if your primary chain has too much slack. Worth a try cause it's FREE!

Re: auto adjust primary chain tensioner
Here's what you do. Accelerate from a stop in first gear rather hard to about 30 MPH and then brake rather hard using only the rear brake without locking up the wheel and don't pull in the clutch until the bike slows enough.
Do this 2-3 times in succession and you'll notice that the noise that you thought was the valve train is almost completely gone now. Low speed riding is a bit smoother also due to less play in the chain.
By doing this, the automatic primary chain will ratchet up a bit tighter if it was loose before this. The acceleration and braking causes slack in the lower strand of the chain and will ratchet it up tighter if it needed an adjustment.
If it wasn't loose there will be no noted difference.
That is most likely the noise that was heard and not the valve train at all.
Sounds strange but try it!
Great point. I actually saw that happen on a Marine Chevy engine once years back. Good point Charley
Thats a really good point...I will run it by the service manager when he calls me...Thanks would not have thought of that.

I have the same year & model, & the same problem. Have you found a fix?
Some say it can be tuned out with the SEPST, Some say ALLSBALLS starter clutch. One said it's the Temp sensor.
