I have been forever working on my bike. I will try to condense this a little because it is kind of long. A few months ago I installed the following:
Drago Stg II heads (bigger valves/ported)
SE Adjustable push rods
40 thou head gasket.
(I have had T-man 555c cams for about 15k miles)
Everything went well. It started right up with a little bit of noise but it mostly went a way about 5 or seconds after start up. I had oil pressure of about 32 psi cold at idle and then as it warmed up, it would drop to the normal 5-10 (whatever it reads but it has always been low) After the heat cycles and checking everything over I rode it. I noticed a tick I couldn't get rid of. I adjusted the valves a few times to make sure that wasn't it and swapped lifters with a new set of Gateman's. It was driving me crazy until a valve in the head let go. So, I pulled it apart.
I put it all back together with new parts. I still have a damn tick. Usually this doesn't bother me because I am building up the engine so there is usually a give and take with something but this didn't add up. I re-adjusted valves a few times, pulled the lifters and checked them. Anyway...
Turns out I supposedly had a "sumping" issue. I was told to start the bike and run it until warm. ( I drove it for a few miles in traffic) then shut it off and pull the drain plug. This is where I am confused.
When I pulled the drain plug, oil comes out really quick (as it should) and then tapers off really quickly BUT it never stops flowing. Is it supposed to stop flowing completely? I am told I should get anywhere from 4-5 oz. of oil in the cup all the way to 6-8 oz. but then it will stop?
This initial dump of oil seems to be like a 6 oz. then tapers off like I said but keep flowing. Eventually it would all drain out .
Can anyone help me with this?
Fast forward to now...I have the same 106, Stg II Heads, but this time I added a "Fueling" cam plate "Fueling oil pump "Fueling" lifters and while I was there upgraded to Drago's 580 cams. My head gasket is now a 30 thou instead of a 40.
One thing I can say is the Fueling cam plate is bad ass. As soon as I started it up the oil pressure jumped to 50-55ish. The ticking noise was gone. It was smooth as a sewing machine. I haven't had that for a while now. I ran the bike down the road and put 60-70 miles in it. No issues, everything seems fine.
Well, I was still curious and needed to change the oil so I decided to check for the sumping issue. It did the exact same thing as it did before I changed over to the Fueling stuff. A large amount comes out then it tapers down really fast but never stops flowing.
Anyway, I am just trying to make sure I don't have any issues. Thanks for reading (if you made it to the end.
