Doc Harley’s Exhausted Tech Tips

[@scottlin777]

Every dealer needs a Doc Harley

[@LowCountryHarleyDavidson]

But then all would not come and visit with me at Low Country Harley-Davidson SC

[@RNintheTrenches]

Great tip, thanks Doc! Nice to see a dealership taking care of a older bike.

[@joeharley87]

Really great tip Doc as always.

[@SixShooter14]

good advice there. Another thing to look for is make sure all the old gasket comes out. I had an issue that a small piece of the old gasket was crushed in and stuck to the port. Put the new gasket on and could not get the flange to line up square. Turns out that bit of old gasket had the new gasket and the pipe twisted and not lining up with the port.

[@LowCountryHarleyDavidson]

That is a great tip….Doc

[@alanwagers7073]

You are the best ! Thank you for sharing ! The education is priceless

[@LowCountryHarleyDavidson]

You’re most welcome. I’m glad you found it helpful. ….Doc

[@robertlevites7146]

I emailed you awhile back about my check engine light coming on my 2017 FLHTK. I had code 154. The dealer replaced O2 sensors 3 times and the last time I had it in the dealer they replaced the smart pro tuner. Well, that didn't fix it either. I remember you telling me you ended fixing the same problem by putting SE mufflers on a customers bike and that fixed the problem. We'll to prove out your theory I put my stock mufflers on for approximately 600 miles and no problem. I ended up putting Krome Werks 4.5 with baffles. So far so good. Thanks for your expertise and knowledge

[@LowCountryHarleyDavidson]

That is awesome, glad it worked out!….Doc

[@schachat01]

Thanks Doc for another important and helpful tech tip👍

[@steventwiddy3402]

[@LowCountryHarleyDavidson]

Thank you, I appreciate the kind words. ...Doc

[@kjm81of]

Always great tech tips!

[@nhrider88]

Another great tip Doc. Keep em comin!

[@LowCountryHarleyDavidson]

Appreciate that, glad you like it!….Doc

[@Chainsaw2373]

Thank You Once Again! I remember your old video about the exhaust gaskets and that also helped me solve my problem. As an old retired mechanic it means a lot to me. I started as a mechanic for Harley Davidson and moved to sports cars and then to diesel and worked on the government fleet.

[@LowCountryHarleyDavidson]

You are most welcome, thanks for watching. …Doc

[@joannecastonguay]

Thanks doc! Love your vidoes and all the good info!

[@LowCountryHarleyDavidson]

I appreciate it!….Doc

[@stevel7071]

Another excellent video thank you

[@martinwall7297]

that's right always change the ex-gasket

[@theodavies8754]

My 99 factory service manual torque sequence for dyna TC88 is wrong,don't know if it was corrected later. Cross reference with metric NM which is correct. The retaining rings are high tensile spring when supplied but lose the temper through heat cycles. Old ones will be soft, new will be a bear to fit with chisel sharp ends. Use copper grease as recommended on the nuts. I made a gasket driver on the lathe from some 2" aluminium. No idea if the new gaskets can be pressed in without damaging without a driver,probably not from my experience. Crossover gasket will also be junk when refitting standard headers. Just do it properly or leave it alone.

[@gremlyn1439]

As always, good info. I remember the fun I had with my shovels and the exhausts.

[@LowCountryHarleyDavidson]

Glad I could bring back some good memories….Doc

[@jondoe8816]

Top advice. I re torque when I change oil. Just to see if it’s loosened off. ,,, might turn 1/8 to a 1/4 turn till the torque spec

[@LowCountryHarleyDavidson]

That’s a great preventative maintenance tip….Doc

[@fernandocamilli4232]

Explained it perfectly.

[@Biker-Jim]

Changing my exhaust on my roadking before Daytona next year, replacing everything exhaust related. Thanks for your expert advice Doc, always enjoy the videos

[@LowCountryHarleyDavidson]

Thanks for watching….Doc

[@shameless6963]

Gonna have to check mine. Didn't think to look for a torque spec

[@bradduffield9603]

Thanks Doc as always a great tech tip.

[@LowCountryHarleyDavidson]

You’re very welcome Brad…Doc

[@chikowhitey]

[@richardhartley7094]

Absolutely right👍

[@CATmanATL22]

Great tip doc. If only people would listen to that advice, but most people have to learn the hard way …….lol 😂

[@LowCountryHarleyDavidson]

You are absolutely right! ….Doc

[@davidlarson3920]

Thank you

[@LowCountryHarleyDavidson]

You are very welcome….Doc

[@chuckflitton5293]

great video Doc. How to do it right!

[@LowCountryHarleyDavidson]

Appreciate that!…Doc

[@mattmattes3913]

I always keep a couple pair of S/E exhaust gaskets in the parts box. Having an older bike (mines a 1987 1/2 FLST-Special), there's just times when your doing regular maintenance that it's easier to just get the exhaust pipes outta the way. Like changing tranny oil on my bike. You can get the drain plug out with the front pipe on but just try to put the drain plug back on safely. Easier to do it the safe way. Same with changing the back tire. Just get the rear pipe outta the way. You got plenty of cleaning to do in the meantime so what's the rush.

[@LowCountryHarleyDavidson]

Love your attitude and been there…Doc

[@mattmattes3913]

@@LowCountryHarleyDavidson Thank Doc Merry Christmas

[@johncasor9698]

2:50 you say 50 to 80 inch pounds.... WOW i better read that in the book ... i have a disc on file... and i have a Book... i check it out Doc... Thanks so much you might be right...

[@willisluckey4328]

I used Genuine James copper exhaust gaskets, and have never had an exhaust leak

[@LowCountryHarleyDavidson]

Nice Tech Tip….Doc

[@willisluckey4328]

@LowCountryHarleyDavidson Thank you for all of your Technical support Doc 👍🏁🇺🇲

[@KamaTanha]

@2:48 1 ft pound = 12 inch pounds, So 60 to 80 inch pounds is 5 to 6.66 foot pounds. Not less than one foot pound.

[@LowCountryHarleyDavidson]

Thank you for the correction….Doc

[@garybryant1701]

How do you replace the stud once it’s pulled out? Tap and use a bigger stud? Doesn’t seem right

[@SIERRA-dx9wm]

Helicoil is a good fix I have gone one size larger tap on stripped out hole and larger bolt That’s a talk real nice hoping for success Do you feel lucky?

[@ihateemael]

in automotive ex shops they used to have a stud made with a large diameter on one end, so you drill out and tap. Otherwise you need a helicoil or similar kit.

[@positivelynegative9149]

👍

[@d1mennis]

If you don't get a good seal on the exhaust you will get de-cell popping!

[@arnoldpadilla6471]

Really!?! 2003!?!? Nice. My local HD dealer won't work on my 2006. To old they say.

[@boxfullofbluzeg2235]

First thing I thought too

[@LowCountryHarleyDavidson]

You’re not alone, I hear that a lot….Doc

[@SuperOperator4]

And that POP POP POP on deceleration!!!!!!!!!!!!!

[@karateman856]

Do it right the first time, pay now or pay later.

[@LowCountryHarleyDavidson]

Well said sir…..Doc

[@westcoast3595]

Rings and gaskets are just an annoyance. Hell. I being an automotive technician for decades would insist on replacing both. Everytime

[@LowCountryHarleyDavidson]

You're preaching to the choir! ...Doc👍

[@johncasor9698]

AT 2:58 YOU SAY WERE NOT EVEN TALKING A FOOT POUND HERE ??? one foot pound is 12 inch pounds DOC... i just tighten mine at 120 inch pound that a 10 foot pounds. i think that 5 foot pounds i too loose needs a little more than 5 foot pounds, i run this bike 140 MPH DOC...

[@LowCountryHarleyDavidson]

Thank you for the correction….Doc

[@billcarson1966]

Which is exactly why I always use a torque wrench when required. Too many caveman DIYers don't get it!

[@LowCountryHarleyDavidson]

You are a person who Gets It👍….Doc

[@donaldcross7978]

Help , People , by Saying Lb. Feet , I had a Engineer Explain it , That Help Quit Making it Complicated The Engineer Explained it stops the How tight when you say inch Lbs vs Lb Feet !!!

[@ronkuzyk3836]

60 inch pounds = 5 foot pounds. Take 60 inch pounds and divide by 12 ( because there is 12 inches in a foot) and you get 5 foot pounds. I am not an engineer, I hope that explains it. Another tip is to use a 1/4 inch ratchet when tightening the nuts.
