    No. The preload is already built into the design.

    The rocker with the adjuster allows you to balance the other rocker to zero clearance for the both. The lifter will pump up to take care of any slop between the cam and the valve stems.

    Awesome info in this thread! I'm currently building a BB olds, and one important steps in the lifters is setting preload, do our bikes require the same procedure?

I don't know if the old lifters are OEM, does anyone know if the OEM lifters had the oil hole? I'm assuming there are no issues using the Sealed Power without the oil hole? It looks like there is an oil galley from the feed line through the rocker arm and back down the push rod so I'm thinking the oiling will still be okay.

    Sitting at a gas station/ convenience store eating a snack watching a group of HD riders all decked out from head to toe in their HD garments talking and walking around looking at each other's bikes. They were there when I pulled in. I ordered a sandwich and eating it now and they are still just walking around. I am just about to leave and they are still just standing around. Ridiculous! Drop dead gorgeous day being wasted hanging around.

    End of Rant.

    Anyway you mentioned that you installed Sealed Power Lifters. Did you use the Sealed Power HT2011 Lifters? They have the hole in the center of the cup. DO NOT run your bike with the lifters you have if there is no hole in them. You will starve the top end of the engine.

    My apologies for the confusion. I just double checked and there is a hole in the center of the lifter bucket. The oil goes up both sides of the motor; the external passages and push rods.

    I looked in the manual and the oil flow diagram shows oil going up through the pushrod to oil the rocker shaft and the valve stems. I have it all back together now but it is a bit of a worry for me now and I wish I had paid closer attention to the oil passages. The oil flow diagram shows the oil coming up through the external pipes but it doesn't show it going up into the rocker arm like I thought it did. I'm not sure what else that oil would be oiling so it doesn't really make sense that it doesn't go up into the rock

    If your'e talking about a hole right in the middle of the lifter where the push rod seats, then no. I had no hole in my OE lifters or the Mellings aftermarket replacements. Just be sure to use a thick assembly lube *with ZDDP* [like the one in my post above] on the cam lobes and lifter faces for the initial break in.

    What Dave said, no adjustments on the rocker arms are necessary if they're working good now. When heat expands the whole rocker arm, the adjusting screw will expand a little more length ways then the non adjustable rocker finger.

    Doc I'm sure it's not an issue I'm just explaining why the engineers call for a lash. Metal expands when it gets hot.I would also think that the lifter absorbs the expansion on the non adjustable side. I adjusted mine with the lash because I want that valve shut as tight as it will shut.Mine also has 2 adjustments,1 to synchronize like all of them do and 1 adjustment for the length of the pushrod. I'm sure you also seen Dukes response above basically saying the same thing. Also back to what was said earlier don't make more to it than what it really is. The rest is just conversation answering and explaining questions that have been asked. You should be able to do the job without touching the adjustment on the rockers anyway and it will stay at the same adjustment you have now.

    OK Dave, now I'm even more confused, can you clarify? Earlier I asked if it was bad to set the lash to zero when cold and the response I got were it's not a problem. What am I missing here? I'm sure I'm not the only one who'd like to know.

    Thx.

    If anything adjusting to "0" lash "cold" will make the valves a little out of adjustment when hot. You are actually synchronizing the valves opening more than adjusting them. I guess the word adjusting vs synchronizing is about the same as when we call the enricher a choke.

    He has them for a 07 and they don't require HC pistons they are just more fun with them,even more fun with Big Bore HC pistons

    Yah, a *few* pennies... Oh well, it's only for 99-03. And I think it also requirers HC pistons too.

    Those are the cams I have in my bike, you need to get the collapsible push rod tubes with them If you don't adjusting the pushrods would be just about impossible.

    LOL, thanks Duke, I don't have any Listerine, but it'd be glad to provide the bourbon. I think I'll be OK though. I would have been less concerned if I hadn't seen the "cam killer" threads on the old site. I just like to know what I'm getting into when there's potential for serious consequences, but I think I've got it now.

    Mmmmm… Listerine. Yummy!

    Just put in 8 ounces, then save the rest for the next oil change.
    A little to much will not hurt the the engine, it could affect the clutch if it's week though, I think.
    You'll be alright buddy. I wish I was there to help you, I love doing this stuff. I like hurricanes, tornadoes, and Listerine too!

    Hey doc, i think you are overthinking this job a lot. Dont torture yourself like that. Its just lifters, not even worn lifters, just leaky lifters.
    i know the internet is designed to scare you out of doing a lot of things but in reality this is a very common issue with hydraulic lifters and gets done all the time. 99% of the times the old lifter is removed and new one installed and that is that. No special oil or break in required.
    i understand your trepidation, its your baby we're talking about. But seriously, this isnt a big deal

    Is there such a thing as too much zddp? Planning to add some Lucas zinc additive for the lifter break in. One 16oz. bottle is intended for a full size engine, so I'm assuming half would be good for the R*. Would the be any benefit or downside to just adding the whole bottle?
    Protects camshaft lifters and valve train during break-in period of motor. Excellent for flat tappet camshafts during break-in or as an additive to an...
