DON’T DO THIS | ENGINE DAMAGE HARLEY DAVIDSON

My friend Matt dropped off his 2018 Harley Davidson Limited by Dave at JD'S cycle Works, I stopped by to take a look at the damage that was created to his engine. The camshaft that was installed, was not only installed incorrectly without the necessary components, but should have never been installed on this motor. Make sure you watch this video and it's entirety, it will save you a lot of money and headache by not going through what he is now.

I don't get why people try and turn a Harley touring bike into a performance bike. I have a couple of Ducati's and a Road King and my Road King is for cruising, I didn't buy it to go fast. Leave it stock and it'll run forever.

[@atrain882]

I agree brother it’s all that damn baggers that started racing like MotoGP bikes

Because any bike under 200 hp is broken, so we try to fix it

Sorry to hear this for Matt. At least you brought him to a reputable shop with an owner who has the knowledge, ability, and integrity to get him back riding. Thanks John for lookin out for our friend and brother. Keep em comin, I'm with ya the whole way. Great content. Be safe brother.

Dave is a mechanical genius, he knows his stuff I'm so glad I got my stage 2 done by him, could not be happier.. Ty Dave & John for bringing Dave to those who would have never known any better.

[@edwinparedesnjusa]

This is why I thank you for introduced us to Dave , he knows his stuff and will tell you straight what it is

[@125saito]

You are correct. Last year I hauled my bike from Minnesota to Pa to have Dave put in a new cam and dynotune my Road King. Still running great.

Dave is the best!!! He is the only guy I let work on my bike. Great job John as this is useful content.

George Bryce at Star Racing says .485 lift is about all you want on stock springs. I’d be comfortable following his word

[@Jslestak]

George Bryce is a racing legend. His word on engine building is gold.

[@frankmarkovcijr5459]

That's the type of damage you have usually in a jet bike when the cam chain breaks. The timing goes out the pissy kisses the bow the guys get broken the head gets torn the cylinders get screwed up probably your crank too. Such a shame that happened I'm so sorry for you good luck with the rebuild

[@user-qw3zt9vl4n]

Thanks for this video John. Lots of good information. Good luck on your rebuild Dave.

What a nightmare! Great work sharing this. Dave is the man.

[@jimmansi1187]

Wow, I learned a lot in this vid, for me a Stage 1 is good enough, my bike has plenty of power as is & can be ridden hard with no issues as I would hate to have to deal with this problem, very educational, this dude seems like an awesome mechanic!

[@125saito]

Good morning Dave and John. Matt, good luck on your rebuild. You're in good hands now. Dave is a top shelf mechanic and a great guy.

[@sandman1585]

Awsome info John. Thanks for sharing.

[@ocglide2566]

When you started this I was expecting to see a different problem like lifters or push rods, I installed the cam in my 114 40K miles ago and was smart enough to research cams thoroughly so I installed a RS 468. That is a pretty dumb mistake to install a high lift cam on stock springs even I know thats wrong.

[@rodneyhanbaum697]

IMO, One of the best videos!! Super enjoyable, explains everything in a short consise manner, why's and why not! Great job!!

[@stevencoleman4149]

There are a LOT of things that need to be done for an engine to benefit from (or survive) a radical lift cam, springs while a no brainer are only a start. I wouldn't call whoever sold your buddy that set up a mechanic.

Great information! So many bikes are built with false information and miss matched components that will put senseless wear on engines . Then a poor sap buys it used and it's junk !

[@TyFromTennessee]

Great video. Seriously man, I learned something new so thank you sir!

[@KrakensGarageandAdventures]

Man, I feel bad for Matt and thus burns my britches that he got sold a package that was wrong for his bike. Ultimately costing him a load of money that wasn't necessary.

[@montejones5788]

The only Harley I ever owned that I felt like needed performance help was an '09 ultra with the 96 inch motor did a stage one and a remap and wrote it over 30,000 miles and traded it for a 103 when they came out rather than dumping 5 grand into the 96 motor to make it run

[@ryant3694]

Bet they didn't even check runout for the pump and cam plate.

How do you know when a licensed builder made a serious mistake? 99% of the customers can't hangout in their garage, this stuff frustrates me and it's not my bike! Thanks for sharing this important information 👍🏽

[@krotchlickmeugh627]

Because no mechanic wants some jack ass that has no idea what the hell hes looking at. Staring over his shoulder watching him work. All that customer will do is ask you if youre sure you're doing it right. The second the rubber mallet or brass punch comes out. They freak out. Drop your bike off and screw off. When its done ill call you

[@loosewheel75]

I’m surprised the stock valve springs withstood as much as they did. That was a terrible combination of parts to put together.

[@garyforestiere7732]

592 ! That’s a monster cam !

[@drainmonkeys385]

Yes….. if you are going to drop a cam in.. you gotta address runout.. on the primary side.. really you might have have to swap everything out including the flywheel.. if you want to make sure it’s bullet proof.. and then you have to address the clutch

[@prosedi17]

these cams are for the track not street bikes,unless you wanna tear down top end often.put duration not crazy lifts

[@semperfipar1299]

The parts guy saw that coming. Then there was the half ass install knowing the customer did not know anything mechanically. Always ask to see your old parts.

[@frankmarkovcijr5459]

Imagine spending all that money to Hot Rod your engine only to have to go back to stock because the Builder didn't do it right and you ended up with a blown motor such a shame.

[@robertperry5272]

[@davehunt8952]

evening, just curious about the heated grips you have. was thinking of adding the same ones to my bike. my ? is, do those grips have a narrower feel. they look like they have a taper to them. really like watching your videos. thanks

[@merlinphumc69]

Highest lift you can run on a stock m8 valve train is .485 that’s what the 30-30 by star racing “George Bryce” is. Lift plays a factor but duration is where the power is made. 107-114 cr480, tts175, or 30-30. All make loads of torque and respectable hp. 124+ depends on cylinder pressure, and desired rpm range. I’m sorry y’all had to experience this failure I’d 100% be calling the installer and I would be questioning why that combination was recommended on a 107 m8. I’m sure this bike isn’t the only one running around.

[@davidjordan5925]

I have 468 zipper cam stock springs never a problem!

[@frankmarkovcijr5459]

Can he sue the other motorcycle shop where you had the engine built because they screwed it up? Does he have any recourse whatsoever?

[@jasonholby8915]

Have the bracket cut and made an inch taller. Then powder coat or re chrome.

[@tobpitbull]

Check the psi of valve spring at installed height and guessing about stock is gone

[@ronaldhicks2965]

Using a spacer plate and longer bolts should allow you to use the tour pack.

[@31Icepic]

Hey John have a question or perhaps a video topic. It seems the S&S 475 cam is the goto, but was curious about the S&S 465. perhaps yourself and Dyno Dave could answer this, or just a different cam to install on your new build. Thanks and Take Care

[@garyehrhardt3136]

Got to do your due diligence

[@TorqueCustomCycles]

Makes no sense why the springs were not changed. Someone was obviously in there because I noticed in the video that the rocker shaft bolts were changed out for studs. So why disassemble all of that change out to studs and not change the springs. My guess is they didn’t have the proper tool to change the springs with the head on the bike.

[@badcompany3828]

I would have went with a screaming eagle 255 cams for a touring bike. Gives great low end torque

Want to take my 2000 road king classic to get dynoed and see what my numbers are. Bought this bike as my first harley early this yr. The guy got a 95 ci kit installed as soon as he purchased the bike. Just curious to know what I'm working with.

[@Roadglide117]

Hey bud, you may already know this, but make sure you have your cam chain tensioners looked at. They were notorious for failure on the early twin cams. Great motors otherwise. If the tensioners have never been replaced, or need replacing look into gear drive cams. Very solid setup. Just my 2 cents. Hope it helps. Enjoy the Road King. Awesome bikes!

[@johnjubie7144]

I suspect that a cam that large might need a rocker arm upgrade also.

[@alfredomiranda7002]

Once again for clarification, when installing a TTS 250 cam ,for example on a 117 M8, one should put on heavier valve springs? Awesome content. Thank you

Which would be better a 465 or 475 cam in 107?

[@jackiesutherland5905]

I really like your page but I do have a question and please don't take this the wrong way. I see that you do a lot of things on your page that companies give you items to put on your ride. out of that how much do you pay out of your pocket for the things that you put on your bike because I like I said I like your page but you know the average guy like me I can't go out in the Ford to do an engine build kit and do a carbon fiber fenders and the high-end stuff like that so I'm basically to be honest with you I'm jealous but that's just my question no offense intended at all.
