Wow thanks for posting this. I'm always uneasy about valvetrain noise since I've never had a good reference for what a knock sounds like. I think I'm good now....
New Buell for me.

Use the video posted here. I was able to get the bike to idle after replacing that hose. I probably need to clean the spark plugs again after cleaning the gunk out of the TB.

You do know what color the coils are supposed to be, right ?
The motor is probably going to be out of my XB tomorrow night. Really all that is left is the 2 isolator bolts and I’m just going to drop the motor using my floor motorcycle jack and lift the fuel tank/frame/fork/front wheel off over the top.

Unless there are pictures, It never happened !
Ok, everyone... let hear your guesses to what’s actually going on with my engine. The big reveal is going to be tomorrow with pics and all. What do you think the noise is?
Mike lowery - crank
Njloco - bad lifter
Me - crank
Cooter - crank
Barrett- piston slap

Wouldn't the crank be more of a thumping sound ?
I kind of thought that too, but the noise seems to disappear for a second when you rev the motor. Usually piston slap gets worse as you rev the motor.
I pulled the primary off a couple nights ago, and rotated the motor over with the spark plugs out. I rotate to the TDC so the rod is still pushing the piston upward then quickly rotate it backwards. If there is a sloppy wrist pin or especially lower bearing, you'll feel a clunk as the rod reverses its motion. I couldnt feel it this time, but my breaker bar had some slop in it, and since the motor was in the frame I had a hard time verifying I was at TDC. I think I was, but it was hard to tell.
What do you think is going on? Let’s see who has the keenest ear.
Shes peeking out from the bottom.
I actually grabbed the bike by the seat rails, lifted up and forward and rolled the frame forward away from the motor. Easy peasy. I'll probably make a stand this weekend to hold the frame upright and more securely.

Last chance to vote on this party people.
Surprisingly the intake seals look good.

So, it looks like Barrett figured it out.
So, what probably happened is that the bike is likely still running the factory stock (lean) map. Now with the Jardine, its going to run leaner. Add on that the fuel pressure was probably falling off as the leak in the hose got worse and worse. It was likely barely able to provide enough pressure to run the fuel injection making it run even leaner. At some point, things just melted down. In fact I think the wrist pins were starting to seize as well.
This also happened. So, they probably spun in the small end.

forgot to say my vote was "whatever barrett says"...
34,
Well you just weren't using your head. Instead of mucking about with the old frapped out XB you could be roaring down the freeway on my(your) EBR 1190RX at 150mph enjoying the big double overhead cam sensation. Probably could have had mine for what it will cost you to get the XB up to spec.

Are you looking for an XLCH or XLCX?
Well, 34, I am not familiar with the XLCX designation so lets go with the XLCH. The why is 'cause no electrical system to speak of, kick start, gravity fuel supply--primitive. Has a big appeal, and I am not in too much of a hurry these days.
My trips are more aimed towards camping and even fishing in some remote lake.
The kickstart on the XLCH might be a problem(kneesville) so am definitely interested in the XR1200--Barrett says they are the bomb.
Offering a twofer on the XR1200--my Uly and the EBR

An XLCH was an older model sports model from back in the ironhead days.
The 2016-up Sportster Roadster is an XL1200CX
Two completely different bikes.

34--I got that--and the XR1200 is in the middle. Yes and some of the late XLCH's had the electric start and one year had both.
Some how I missed the XR1200--seems like a good choice. They are out there from $5-8K.
You told me the Roadster is like carrying a passenger around on the Uly--ha ha.

Other weirdness...
I received my RH scoop last week and wanted to verify that nothing was missing/weird/etc. Good thing I checked. For some reason I couldn't figure out how it was mounted, although I had installed 5 or 6 of these in the past.
How does this mount again?????
WTF? Seriously people!
Also this....
Meth is bad people. Don't do meth.
