I would like you to do a video on tuners for the average guy. Which is easiest. Which is best. From a guy who just wants a stage 1. And up. It seems to get confusing. And there are so many opinions on tuners. That it's hard to decide. I'm just wanting a stage 1. But want longevity and cooler running motor

[@darrellochs6700]

For someone that has ridden Harley’s for years but I’ve never broke into the power train I love your videos. They are very informative and helpful. Thanks for putting them out there and please keep making them.

[@TuckerSpeed477]

Glad people are finding them helpful. Thanks for watching.

[@ken2tou]

Fueling HP Plus lifters and adjustable pushrods are quiet and great performers in my 110.

[@TheTrex284]

I just ordered the 574 chain kit from Tucker Speed for dyna screaming eagle 110, I’m super excited

[@MapleBar777]

This is exactly the type of educational video I need. These are awesome and easily comprehensible. 👍

[@TuckerSpeed477]

Glad you found it helpful!

[@AsherS.HavensIII]

Best explanation of valve train on internet imo. The cavitation of the lifter(minimized in a short travel lifter) is minimal until absolute efficiency is wanted like you said for racing with 150+ hp engines. Thanks for a great video. Im subscribed looking for any other videos you put out. Thanks Sir

[@TuckerSpeed477]

Thank you! Glad it was helpful.

[@PitCrewMotorsportsLLC]

great info Tony keep em coming

[@TuckerSpeed477]

We've got lots more coming!

[@Breakout2018]

Great video! Nice info!

[@TuckerSpeed477]

Thanks for watching!

[@stanwerner7484]

thank you for the info---Question: I do not see Fuelings adjustable push rod for the M8? it only states "Twin Cam" on their web site?

[@TuckerSpeed477]

It looks like Feuling is currently only offering one piece pushrods for the M8. S&S does have adjustable pushrods available.

[@pb68slab18]

When it comes to tappets for the Harley V-twin , JIMS! I use their Power Glide lifters in Pans and Shovels.

[@tennesseebound6597]

What’s the advantage or disadvantage of a full travel versus a short travel lifter?

[@TuckerSpeed477]

Biggest thing is the area under the piston inside the lifter is smaller on the short travels. There for the affects of aeration are less. Aeration will cause a decrease on valve lift, when the lifters pushes up against the pushrod it will compress the air and lessen the lift.

[@FireMedic541]

If you’re spinning the pushrods after adjustment, how much resistance if any should be felt when you spin them with your fingers? feuling 574 reaper with adjustable PR and Full travel rollers.

[@jonathanslack259]

Man did I need this! LOL! At least I can say I kind of have a way better idea at how this works!😁

[@roncoburn7771]

just installed fueling race lifters in my 160 HP m8 1 is making some noise trying to figure it out now.good video

[@TuckerSpeed477]

Thanks for watching. Good luck, hopefully it’s something simple.

[@joelnaveira720]

Great knowledge, installed S&S quickies in my M8 at 3 1/2 turns. Is that too little for the adjustment?

[@1962egl]

Guy at s&s told me 3 turns and one flat is perfect for quikie pushrods. I did 3.5 turns on mine though. It worked perfect.

[@glennwingfield8681]

I personally installed the S&S cam chest kit in my 2017 SGS I used a U-tube video to do the work. 10k miles later, it’s still running great.

[@1962egl]

If the goal is .100, four turns is to much.

[@BackwaterJacksSA]

2012 103 street glide with woods tw222 cams and fueling lifters. Are stock push rods still ok?

[@TuckerSpeed477]

We always recommend replacing them when installing a cam. The stock ones might be fine but you might as well change them while you're in there, they will also make installation much easier with adjustable pushrods.

[@jamessmoth8683]

My bike already has the SE Stage 3 kit with SE adjustable pushrods, I want to change the cam to something more aggressive. Should I change the pushrods also?

[@TuckerSpeed477]

You should be able to reuse your adjustable pushrods.

[@brianthomas1359]

I believe Fueling lifters are made by Hylift Johnson, but not totally sure. What is your opinion on the Hylift Johnson's?

[@coreyboren3476]

I’ve got a 2023 lowrider St 117. I have the star 3030 cam coming in but I’m trying to find the right combo lifter + pushrod. I can’t find the adjustable pushrods on fuelings website for the m8.

[@TuckerSpeed477]

@@coreyboren3476 I don’t think Feuling has an adjustable pushrod for the M8, may have misspoke in the video.

[@coreyboren3476]

@@TuckerSpeed477 okay. No problem I could have just assumed they did also. What would you recommend my setup be . I fully understand how to adjust and everything. I’m running 2-1 Sawicki and star 30-30 coming in. Going to upgrade my manifold and breather. I’m stuck at what lifters and pushrods though. I know star is .485 lift. Says stock springs are fine.

[@TuckerSpeed477]

@@coreyboren3476honestly the S&S quickee pushrods are a great option. We’ve been running them in a lot of builds. With your setup the S&S lifters and pushrods would work really well.

[@jamesstafford62]

The owner of Star Racing who makes the 30/30 Cam uses the HD Screaming Eagle adjustable push rods on all his builds. He says he’s never had a failure or any problems.

[@JCunningham21]

In my 128 with stock valve springs and a .475 lift cam the s&s quickies rubbed the tubes.

[@hydroboy35th]

I have a 24’ Road glide and just purchased the SE-511 cam kit with their pushrods/lifters. Once zero lash is set on the pushrod is it 2-1/2 or 3-1/2 turns until it’s halfway down the lifter? I can’t seem to find the info of the thread pitch on the pushrod or the depth of the lifter.

[@theodavies8754]

Measure the top of 10 threads with a digital Vernier. For 20 tpi 10 will equal ½" or .500. it's ok to measure the top of 5 which gives you .250 for 20 tpi. The more threads you measure the less error you get. 16 tpi will give 0.500" over 8 threads ect. Might have to do a bit of basic division but make sure your logic follows the rules.

[@shoey5406]

fuel moto and woods products for me !!

[@TuckerSpeed477]

We use a lot of their products as well. They make great parts.

[@BigGeorgiaBoi]

Can you used fueling pushrods and S&S lifter

[@TuckerSpeed477]

Yes you can mix and match.

[@JW-ROADKING17]

Anyone using the new woods platinum lifters? Fuelmoto swears by them nowadays. No needle bearings to fail but only been out like a year....

[@tennesseebound6597]

What’s your opinion on the screaming eagle adjustable, I’ve read a lot of good things about there adjustable s compared to others, S&S just seem to thin and cheap.

[@TuckerSpeed477]

They are actually a very nice pushrod as well.

[@jerrylong381]

I have a 2000 TC 88 with 15k miles, It has a tick on the front cylinder when at temp (200°). I pulled it apart to replace the cam chain tensioners and check pinion runout, leaving everything stock because, money. Everything looked very good, runout at .0025", rocker shafts tight in their bore and no slop rocker to shaft. I couldn't see anything wrong on the lifters. Cams show no wear. I went a head and put rocker lockers in it, reassembled and it still has the tick. I intend to put a gear drive cam kit in it, but that won't happen until next winter. Do you think premium lifters with adjustable rods would eliminate my Twin Cam tick?

[@TuckerSpeed477]

Yes, a good quality lifter and pushrod will help in quieting down the valve train.

[@kdar93]

I was thinking of going with a cycle roma 485 cam with fueling solid push rods no my 23 low rider st will that work? thank you

[@TuckerSpeed477]

Should work fine. Just need to make sure you get the correct pushrods for your setup.

[@thomsoncustombikes]

Yee!

[@LarsGalbraith]

Thank you very much. That was very informative. I am I understood it all perfectly. Did a great job.

[@JCunningham21]

you need adjustable pushrods to find out what solid pushrods you need. 😁

[@Dipndots87-ms6ds]

What ever happened to people doing the math to find out what length push rod they need so they can put solids in? Solid push rods are superior.

[@lesrinehart933]

What wears lifters out

[@FireMedic541]

Lack of oil changes, excessive bearing play, and valve spring failure
