Woods Lifters Question
Thinking of putting a better cam in my 2011 Limited 103 and wondered about the opinions of also replacing lifters with Woods directional lifters. I have a Fuelmoto Stage 1 on the bike now. Thinking a medium lift cam like SE-204 or Woods TW-555. I have 10,000 miles on the bike. I see posts of some replacing them and others not. Seems its done more on higher mileage and higher lift cam installs. Is it a requirement or just a good item to do. Does it quiet the valve train down any. Opinions?

Woods lifters are precision made hardware. Many have claimed reduced valve train noise; some say not so much. They did reduce valve train noise in my 107" and I will probably use them in my next build as welll. There is not enough mileage on your OEM lifters to justify replacing them but that's your call. There are other options like VThunder and HQ Black Ops that many have had good luck with.
Why not upgrade cams and replace the stock pushrods with adjustables so you can adjust the preload on the OEM lifters and see how that works out. You can replace lifters later if you think that will solve the problem.

Thanks, that is an option that can be done later and significantly reduces the initial cost. Still have not decided if I want to learn to do cams on my almost new Limited. I'm a capable mechanic but not experienced at wrenching on HD's beyond routine bolt on stuff. I've watched the S&S video, read Atrain's post and have a service manual but just do not want to have a problem.
Another question: Saw a post on another site suggesting increasing the preload on the lifters to quiet valve train. Is this advisable and if so how much additional preload distance should be used. Most directions I've seen indicate lifters should be compressed about half of available compression distance when pushrods are adjusted.

You will need to replace the OEM fixed length pushrods with adjustables to increase lifter preload. Increasing lifter preload has helped reduce valve train noise for some but not for others. With adjustable pushrods, you increase preload from .100" (half of the available travel) to .110", .120" or more; it's a trial and error thing. If you increase from .100" to .110" and there is some improvement, try .120" and so on until but you don't want to increase preload much past .150".

Just put a set of Woods tw-555 cams in my buddies 08 Fatbob.We used the stock pushrods and there is no valve train noise at all.We were both really impressed with those cams.Runs like a raped ape!Pulls hard and revs quick.Totally different bike now.
