I just did a top end overhaul / service on my 2011 FLHTK Touring Limited/ I dis-assembled the entire upper part of the engine because of valve train noise and found Mega Caron Build-UP.
Cleaned everything first, scraped and scrubbed Combustion Chamber, Pistons. Changed Pushrods and Tappets. Replaced ring on my SE High Compression Pistons. Replaced Oil Pump because it had score marks on the inside gurator and pump housing. Cleaned and honed valves, washed real good for abrasive materials etc... replaced cracked V and H headers below the six speed near mounting bracket etc..
Put everything back together and have four (4) BOLTS LEFT OVER. they are # 6 Flange Bolts (Black). The same bolts that go into the Top Breather Assembly, (2) on each cylinder head...(the smaller / thinner of them all. I feel like a jerk but I took pictures, used the service manual, you tube and help from others.
Dis-assembled and re-assembled and can't find where these bolts came from unless they came with the gasket kit I bought which I doubt because they looks used.
I did not dis-assemble the crankcase or the transmission. I took the bike out today for a 150 mile run and ran fine except I think I need to adjust my clutch...slight slippage up a hill with open throttle up a hill and balls out.
These Bolts are labeled 6 on top, 6 points or flats... which I believe is 6mm and they are Hillman black 1.75 inch or 2 inches long to end of head.
Anyone have any info on this I would greatly appreciate it
Thanks-

Sounds to me like one of your good buddies kind of snuck up on you and added a couple just to get you all sweaty and worked up.

The H-D gasket kits come with the new low profile breathers that use shorter bolts.
If your gasket kit didn't have the new breathers it's possible the kit contained new breather bolts anyways. So you would have extra breather bolts left over.

In regards to the excess carbon build-up, run some Sea-Foam thru that, and/or plumb the breathers to the outside.:)

Extra parts are completely normal.
Your sure they aren't from the gasket kit? Maybe a helper used the new bolts from the kit and left the old ones on the floor?
