How To: Clean and Seal a Motorcycle Gas Tank | Yamaha RX50 Restoration

In this video, I show the process of cleaning and sealing my rusty 1983 Yamaha RX50 Gas tank using muriatic acid and por-15 gas tank sealer! This is a VERY important process, it will save your carburetors from getting clogged up, and could prevent your gas tank from leaking, gas leaks are very bad!
POR-15 Gas tank sealer is bad ass! It can seal pinholes, and even cracks!
Watch me restore a much worse gas tank: • Restoring a Rusty Gas ...

Recommendation : place some glad wrap ( plastic food wrap ) or rubber glove; under the gas cap to protect it from the sealer. There is a really tiny breather hole that you DON"T want to block !!!!! . :)

[@mobilecellmart7442]

Thank Paul, That tip is very important on other tanks.

[@addisonsautoserviceinc.7075]

Just a tip for you, never EVER shake any sort of coating that you need to use to create an air-tight bond. Your going to create very small air bubbles in the coating and will therefor make it porous causing rust to return. Stir it instead.

Just found your video. Now restoring my 1980 Honda PX50. Thanks!

[@shmez33]

This video gave me ~*Special*~ vibes. Ready to seal my bikes tank now.

[@Spitfireseven]

This has been an excellent video. It was so loosely put together that while it was one hundred percent effective, it was also fun and enjoyable. I loved it.

[@kevinscheifele6833]

I have done this exact procedure. Works amazing.

[@gage133]

I have a 1984 Honda 3 wheeler with a very rusted gas tank along with holes in it. This method was 110% worth it. You saved me a ton of money instead of fabricating it, possibly ruining it and spending quadruple the money!!! Very much appreciated !!

[@kylemartz2251]

2 comments... 1. I lost it when you showed the man and the giant rooster. That was genius. 2. please consider making the font color gold in the opening title “Gold Guy”. To me that is your signature. Love your videos.

[@charleskuss8538]

Finally, someone who understands that to get a long lasting seal, your prep work [cleaning] must be first rate.

[@Tech-qt2yg]

I own a 1996 yamaha rx100 and it's the exact problem but hey thanks for the additional knowledge I never thought it could be restored👍👍🔥

[@ParkerEdwardsParties]

Killing me pushing that tank around on the concrete!

[@966Mako]

Thought the same, until he said he was re-painting.

[@auctioncrazy8053]

I'm gonna do the same thing I'm scared

[@davestrain9529]

OH GAWD im 50 years old DONT Work that SPECIAL tank around on CONCRETE!

[@krotchlickmeugh627]

@@966Mako thats fine. If you really like to do bondo and sanding.

[@lbdrummer3]

We use to do this when I worked at a shop a long time ago. It's the only way to prevent rust from plugging up the carb. Once they start rusting, it's done, gotta coat it or trash it.

[@MotoMango]

Haha the cut to the "special" clip kills me every time 😂😂

[@vinnymartinez2579]

Yo how do I let it dry cap on or cap of do I rinse after if so what also have you ever done anything shorter than a 96 hr cure

[@itssyedfazal]

Same

[@kimberlyv5846]

Thanks for the great video! I have a red 1983 rx50 that I need to do this to, your tips will help me a lot THANKS! I also need to rebuild the carb, that or buy a new one.

[@codelicious6590]

I have an old 70 yamaha HT1 90cc enduro I've been dinkin around restoring and when I took the speedo cable off I noticed it looks exactly like the flex shaft from my 2016 Chinese dremel tool! Exactly the same inner rotating piece!!

[@fatrat137]

This guy fcks.... for sure 😎 Took forever to find a proper gas tank resto video

[@mobilecellmart7442]

Thank you for making this video. Nice Job!! Very Helpful as most vintage bikes don't have tanks available on Ebay!!!!

[@jeremyandrews4022]

Nice. I appreciate the help. Actually the first time I’ve heard of por15 sealer.

[@joelsdobermans45]

Awesome videos love to see someone fixing things like I do ( without a million dollar shop and tools)

[@joelmcintyre3061]

Gonna give this a try on my R1 tank before I try and find a new one. Thanks.

[@joelmcintyre3061]

Just an update. I tried it and it works. A bit messy and the fumes from the acid tore my lungs a new one. Have done a couple treatments and all but a couple spots have come off.

[@codelicious6590]

Gosh I love that little Special.

[@santo3120]

Love how the sound effects match the year of your bike!! :). In reality... really enjoyed and learned! Thanks for sharing!

[@gabrielgrucela]

This video was great. It was funny and informative at the same time. Keep it up!

[@kylemcweeny878]

Came for knowledge left amused

[@johnwiechel]

EXACTLY what I was looking for. Much appreciated man!! Can you get the tank sealer at a auto parts store? . Got a new sub!!

[@martinperez8502]

Great work goldguy good content sure will apply ur knowledge to take on my gas tank love ur skills keep up the good content always and cant wait to see a vid of that tank painted

[@bradleyshunn8679]

Thanks so much I've been trying to clean my yamaha xj600s but failed at getting a good clean 2 times I think this will get the job done 3 times the charm right

[@mcspr21]

thank you very much for sharing

[@My68Tempest]

Sweet vid. I need to do the same with my Yamaha R1 tank. The gas that came out looked more like thin chocolate sauce it was so bad.

[@kpsmith4241]

lol i love when the scissors fell apart you turned them over and they said Harbor Freight lol most people give them shit but most of their stuff is decent for consumer use.

[@georgetucker336]

Great fix. Will try next fix.

[@lstruggy]

New sub! Bro is sealing the motorcycle fuel tank to get rid of rust the same thing as “flushing” the motorcycle fuel tank?

[@4fiddy_a_aron]

Great tips! I've also used a cork I shaved down to fit in the petcock hole which is a little easier to take on and off

[@mellamodiego8458]

im thinking of doing cork too….does the muriatic acid eat through it? also ive seen guys do muratic acid for only 20 minutes and say you shouldn’t do it any longer but this guy did it for a whole day…which is right?

[@4fiddy_a_aron]

@@mellamodiego8458 the cork held up fine. I even used a synthetic cork which worked just as good. I only had surface rust so I did it about 20 minutes and diluted it, I suppose you could go up to an hour if you had to, otherwise your pushing you luck unless you diluted it with water

[@ghettosanta2786]

Thanks I need to do this to my ts185 gas tank and a pinto gas tank I have thanks man definitely hoing to do it now that I know it works

[@ericanderson4258]

Hello, Thank you for your help. I am not sure if I can use the sealer. I have a 1984 VF 1000f. The pepcock valve control is operation on the side of the tank, I heard am concerned there might have a tube inside the tank and I am not sure if I should take the risk. I was told . Do you hand antho3 Ok thank

[@gc6391]

Great video!!

[@cubul32]

Ever tried Tamco gast tank coat/sealer? What are gas tanks usually made of: steel? I plan to extend a Grom gas tank with sheet metal/welding so I'm researching. Thanks for the clip - exactly what I was looking for.

[@sidhamby5656]

Where do you buy the Por15 tank coating? Walmart?

[@melm8224]

Did the sealer peel??? Or still good?

[@iLike2Bike]

In the first minute I laughed 3 times. I love this

[@TipsyMarlinTravels]

I just watch your video about cleaning a gas tank and sealing it. After 3 years how is the tank sealer holding up? I am about to do my tank, acid and sealer and was wondering if the sealer has started flaking off and plugging up your carb or strainer.

[@Foysol27]

Good work Special 😎😎😎

[@dannyboy163]

cleaned out my fuel tank with good ol vinegar and gasoline wash. Topped it off, went for a ride, everything was great. a week later, the bike won't idle. i look inside the gas tank and it is completely rusted, and the gasoline has turned a brown color. gonna follow this exact video, and clean out the carb

[@rikkiroxx1430]

I'm following you and like your methods. Bravo. I'm doing this method today on my 75 ts250. I only wonder how do you know the sealant is going to work if there's still some rust in the tank?

[@jamiehamblin7204]

Thank you, that was "special" 😅

[@nephicus339]

On Yer Bike sent me here.

[@abhisheksharma3662]

i have a Bajaj pulsar 150 DTSi I will try this. thank you for your tips.

[@randypullman1155]

Nice vid GG...a gallon of vinegar,600 bbs, shake every hour, 36hrs, rinse with water, acetone and leave in the sun does a nice job. Zero risk.

[@randypullman1155]

Heat gun can melt the glue that holds the tank together.

[@randypullman1155]

I leave the tank upside down that way if its thick its thick at the top...out of the petcock area and outta the fuel and in the suns heat

[@tristanhickenbottom4372]

You don’t use a sealer at all then?

[@GjpRion]

Cant wait for the next episode 🛵

[@lordracula2461]

Awesome video dude this helped me a lot

[@MotoMango]

Muriatic acid is no joke. I use it at work all the time; we use full PPE and always under a fume hood.

[@GoldGuyRides]

Yeah it is no joke. What kinda work do you do?

[@MotoMango]

@@GoldGuyRides I'm a marine scientist. I work with microalgae and shellfish for NOAA. I use the muriatic acid for acid bathes haha nothing fancy.

[@GoldGuyRides]

Wow that's awesome man!

[@MotoMango]

@@GoldGuyRides I think so! Thanks man!

[@ogichidaawag3244]

Awesome.. Thanx

[@ranojoyjoseph589]

Hi, I was abot to clean the rust from my gas tank. So just poured a little muric acid inside, and smoke started coming out. Is that normal or I am doing something wrong. I poured some water before. And one night back I sparayed some wd40. Please let me know if the smoke is ok,or something wro ng.

[@eriksmith7142]

Thank you for these videos man

[@ankea8757]

I have 1974 Kawasaki Z1. It has been in the carage for 3-4 years now, and I used Annitrol to get rid off the rust. Then "washed" the tank with gas. Then filled the tank and put in the gas preservative, because bike will be without using in the carage. So.... 10min from "gas washing" tank was looking so rusted again. Before that it was beautiful and without any rust anymore. I have been thinkig about buying the kit where come the cleaning and the sealing materials. This is so frustrating that my work for the bike is useless. I did that at autumn and maybe at spring or summer I will buy the kit.

[@mehere3013]

Where did you dispose of the chemicals and fuel

[@Foysol27]

Nice work

[@flyingmollywhop4228]

this might be great because i have a tank with pin holes and a hairline crack. might seal it up.

[@johnsingleton8571]

Thank good info

[@snowmen707]

If you leave the acid in the tank for two days will it work better, or is that too long and could cause problems?

[@mikebaird3867]

Cant help but laugh everytime the " "special" clip pops up ahahaha good job

[@bryanlettow4389]

It won't flash rust when using the heat gun?

[@stephenlove8067]

Very good video.

[@mellamodiego8458]

ive seen people on youtube say you should not let muratic acid in the tank for no more than 20 minutes and you let it sit over night ….which is right?

[@mahiralkhalil6109]

thx buddy

[@organic_masilaraj]

Sir after applying the sealant it doesnt rust again....or again we want to clean this tank as mentioned in this video the same again....after some years... is this the same procedure apply to the car petrol tank also....

[@Sig320]

Just put my first coat on my 09 Yamaha FZ6R and it looks good so far. I’ll put 2 more on then let anyone know. It’s hard finding a video of someone doing it with a modern sport bike gas tank.

[@throughlywet3722]

I have a small gas tank which holds about one and a half gallons. So do i put one gallon of muriatic acid and the rest water to the top?

[@user-hy6lu7nt4k]

awesome very helpfull thank you

[@sonofashepherd6668]

What happens if you have some small puddles due to the sealer? And can you remove the puddles some how?

[@nathanlarson1851]

First time seeing your videos. Subbed instantly based off the into 😂

[@hypervlogs4067]

tks

[@SeamTressGaming]

Hello! I got a question. How to unstuck the gas cap? Mine is that one kind that flip(?) to open. Thanks for the video anyway...

[@GoldGuyRides]

Spray the whole gas cap mechanism with pb blaster! (A penatrating oil)

[@mikeeger7581]

U can use apple cider vinegar or just white vinegar also,, right????? Instead of the acid??

[@Bassplayingboy]

What is the process to recoat a tank that was coated years ago and needs new coating? There are some metal spots coming through the original tank coating

[@er4989]

Hello, I gonna try to do your process! Just one question: did you use pure acid or you mixed it with water? Im wondering if pure acid could harm or damage my tank if it sit more than 24 hours. Thank you!

[@823peterdotie]

Do you know if the sealer has some heat resistance? Will I be able to powder coated afterworlds? Thanks.

[@handyman7297]

gasoline wont remove the fuel tank sealler?

[@colinsharp1314]

Great job

[@mick-tl5ui]

I am going to give this a go. This acid is not available in the U.K., its called Hydrochloride acid here. Can you tell me what concentration of acid is in Muriatic?

[@Addictraining007]

Really heplful A big thank you ! 🤘

[@belgianwaffle1693]

Just forget about the fact in his intro he jumped in like a super commando

[@jeanninesosa8115]

Muratic acid wont cut thru varnished gas. You might get better results using a fast flash lacquer thinner and let it sit for a few days. Empty then fill the tank up with vinegar. Then rinse with thinner again. After that and you know that your tank is really dry you can treat cote. Also I have a long air nozzle that I put in the tank to see if any stubborn residue is hanging on in the corners.

[@jijoet5491]

Why your muriatoc acid don't produce smoke like when I pour it in my toilet bowl it smoke like a burning twig

[@lynnh7694]

Cool deal, what do you think about evaporust and did you ever use it?

[@GoldGuyRides]

I have used it, it takes a while to dissolve the rust but eventually the part will be very clean..In my case it took about 2 full days to dissolve all the rust.

[@lynnh7694]

@@GoldGuyRides Thanks for the response, I have purchased the Evaporust but, I have never used it before and was wondering how well it works. I just ordered the Por-15 tank sealer. I was just going to use the Evaporust and that was it. I'm glad I saw your video so I can complete the process.

[@mikemiles3068]

Great video! 👍

[@markojerkic1210]

When will you take the TS185 on a test drive?

[@Alexander_Meyer]

Thanks for the video, would the sealer mean i can store the tank without fuel and it wont rust on the inside?

[@GoldGuyRides]

Yes!

[@rameshultra607]

Super

[@melm8224]

Can I use hydrochloric acid instead?

[@Ira-fm1xm]

Hello. Hows your tank to date?

[@CSPAR44]

I just drained all of the gas out of my tank the other day and and noticed that the original sealer was chipping up. Is the muriatic acid strong enough to take all of the old sealer off?

[@tristanhickenbottom4372]

Cosmo Sparshatt I used acetone then muratic then paint thinner and that seemed to work best

[@handyhippie6548]

uhh....where's the link to the ts 185 vid? i have a ts 125 i just bought for $75, and the tank on it is in bad shape. i'll track it down, but i was kinda expecting a link to it. other than that, awesome vid, thanx!

You stir the sealer so you don't get bubbles.

You said Yamaha never actually produced the RX50? Was it a dealer option or something.
