[/B]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).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.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.
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
Whats the possibility that you got new bolts with new parts and the two that are left were replaced?
You said bike is running OK, you ran it for150 mi. From where I'm sitting it's OK adjust the clutch.
