Bro as someone who doesn’t know shit about this stuff, I appreciate you taking the time to teach how everything works. Awesome vid

Everytime i watch one of your videos makes me have to work on my bike. 🤣 and i love it. 😁 keep em comin brotha.

Those 80s petcocks wrecked my life so many times as I knew nothing about how to use them correctly. I ended up going "modern" with fuel injection. Never knew bikes could pee themselves, after half of dozen times (all my fault) & 1800 bucks later I sold them. Thank you for the vlog, GREAT topic, nice Link! p.s. nice job keeping it rated PG

Excellent explanation, well done. Just rebuilt the vacuum petcock on my old XJ600, it’s almost identical to the one on the DRZ. I’ll probably get a standard petcock when I pick up a DRZ.

Thanks for the info! Ditching pulsing vacuum style in the near future.

Good shit as always buddy, thanks for including the part number for the aftermarket petcock in here

Thanks 👍

Thanks Dad, I mean link.

great break down Link !!! ill have to swap ours out when we get the bigger tank. hope you guys have a great weekend brother.

Great informative vid as usual Scott. I must be lucky my 16 yr old petcock(which I check regularly by running the fuel line which goes to the carb into a jug for a couple of nights) does not leak a drop although I know that could change at any time.I do have on the shelf a DRZ400E petcock which gives you the same reserve as the stock one and will get round to fitting it at some point. Ride safe from the UK Martin

I know you're busy now with the GSXR, but i'd love you to do the Free Power Mod on the DRZ, no one else explains or shows things as clearly as your videos do!

Nice job! Yeah, you're probably right, on assuming that they designed it like that to prevent gas from spilling out, in the event of an accident. (Even though, it's only a 2 - 1/2 gallon tank) safety features, like putting the squeeze bar on the handle of these newest pushmowers. Ridiculous... My old 1950 Massy Ferguson 135', just has the old standard petcock.. you have to remember to shut it OFF. Just like remembering to park it in gear, and set the brake.. really difficult '. 😅. Now, for best performance and piece of mind, we have to go in and remove all that shit! Put it back the way that they used to be.

the drawback of less reserve fuel on the standard petcock, easily remedied by laying the 300 lb. bike on it's tank petcock side to refill the carb...got me out of trouble a couple of times or more with the oem petcock.

I couldn’t run my gas line the way that you did, it got crinkled up right off of the petcock. Same petcock and fuel line. I ended up having to go across the carb and back to get it to connect without crinkling up. Hopefully this doesn’t cause an issue.

Love u bro , u always help me ❤

Solid intel explained perfectly and delivered brilliantly. As you were explaining the fuel line routing and the choke interference issue I was noticing the fuel line clamps ,are those mini ty wraps ? They look slick and clean ,traditional clamps are bulky and awkward looking compared to what ever you are using. What's your secret?

Thank you. Great content!

Great info as always bro keep ripping

What size fuel line do you use? From my understanding the 1pz shutoff is 9mm but the drz barb is 8 mm. 5/16 seems like it’d be too loose for 8mm barb but 1/4 seems far too small for 9mm

My DRZ vacuum operated one failed. Oil sump was full of fuel. I hope the motor isn't damaged. Waiting on new petcock.

Do you have a video showing you taking out the TPS? Idk where it’s located or what it looks like. Thanks!

Hey man, first of all, thank you for that video. It helped me understand a lot of things as a beginner rider. Second, I have the stock petcock paired with the keihin fcr39 carb. My bike won’t run when the petcock is at the ON position and will stall on idle at the PRI position. From your video, I can understand that it has something to do with the vaccum of the petcock since there isnt any hose or vaccum block on the vaccum port. My question is, while I wait to buy a ON/OFF/RES petcock, what can I do to make my bike rideable? Block the vaccum port of the stock petcock? Thanks mate!

Where did you buy your gas line and filter from a auto parts store or did you order it from Amazon or what I saw a filter like you have on the Amazon I think maybe a K&N Filter are tusk filters I like that fuel line too it looks good on your bike and it'll look good on mine if I can find out where you got it

You should start leaving links in the description to the parts you use! Please!

Do you shut the petcock off each time you park the bike? My understanding is if the float valve sticks and the petcock is left in the on position when you park the bike, gas will flood the cylinder. Remembering to turn it off and back on would seem to be the only drawback. That and the reduced reserve range. Switch to a standard petcock and removing the PAIR valve gets rid of all those vacuum lines and fittings which is nice.

Awesome videos man. When your replacing the petcock, do you need to remove the gas tank? I imagine as soon as you unscrew the OEM one, gas will flow out everywhere all over the engine. Curious as to how you replaced it. Thanks man

Well to no surprise mine is definitely leaking - taking your recco and buying the petcock you installed. Question: what did you do with the vaccum line off the carb? do you cap it or just leave it?

Thanks Boss!!!

I've yet to find a solution for my petcock being too short which makes it so i can't put it on reserve. Is there a specific one that is longer?

Do you need to turn the peacock to off at every stop or only when you’re parking it for awhile?

Another quality video

Thanks for all the help. Have you ever figured out the total cost of all the upgrades you've added to your bike?

Thanks for the video! Any chance you know what fuel filter you’re running on that fuel hose?

Great Video , where can I get the garburator vacuum plug and is there a part # for that blue plug ? My DRZ is making a lot of back fire when I shut off the tootle , maybe it is cause by the bike running lean since I did not plug the vacuum hose .

So we’re forced to delete the pair valve by getting a standard petcock right ? Just making just I understood correctly at the end you put a blue plug on the carb that went to the pair valve / carb ?

Hey Link, at around the 8:25 mark on the video you can see the lines on the petcock going to the carb. It’s seems like you have a little fuel filter in the line. Is that a fuel filter? And if it is which one? Also do you think it’s a necessary “mod” for the DRZ400SM that helps protect the engine/carb/jets? It’s my only form of transportation and I wanna protect my baby the best I can

heads up to everyone - this works but you need a smaller size fuel line and to delete the TPS to make it work.

I personally hate manual petcocks....you have to Remember to switch them On and Off, or get gas in your oil, cause Needles aren't really designed to withstand the pressure with the bike off. I guess for off-roading applications, simple is better, but for riding on the street in 15 years I've never had a vacuum petcock leave me stranded! But I also maintain my shit and make sure to visually inspect things often....if I have doubts, I rebuild or replace. But thanks for the informative video.

Man I've got a question. I've got a 2014 drz400sm. I put the lower links on but I can't get the front to lower. I loosened the 8 bolts but it's not budging. What am I doing wrong.

The gas in the oil problem is because of a leaking needle/float problem in the carb not the Petcock. Without a vacuum valve how does a manual petcock prevent this issue?

What kind of plastics do have on there brother ?

Isn't using the original vacuum operated petcock on prime mode the same as using your new petcock in the on position? Just curious about what the benefit is here. For the petcock that you are suggesting, You will need to turn your petcock off after each ride right?

This is great info. Why did you change yours? Was it leaking? I recently developed a issue with my 2021 SM where my choke dosent work. Can only start the bike and keep it running by giving it throttle. It idles by itself withthe choke off once warm. I wonder if the peacock vacuum could be related.

What gas filter did you use? Mines keeps leaking from the bottom hose coming from the filter.

I've taken my gas tank off and left it in the ON position but gas is not coming out of it... is that because of the motor is not using vacuum?

please tell me yu went back to stock carb for the video purposes… smh . FCR replica gave yu issues ?!?

What size of fuel hose did you use for the replacement?

Where did you get the purple fuel line?

Wait so if u have to put that spacer you run way less fuel on reserve

Where do I put the vacuum stopper on the carb

What kind of fuel line is that? Does it hold up good?

Hey would my DRZ cut off 10min into a highway ride due to a leaking petcock? My DRZ would run for about 10min on the highway then shut off. It would take a couple tries to start up again but it would start then cut off again after 10min. I noticed the petcock was leaking I hope this fix solves my problem. Thank you!

So I’m going with her after market tank. So I’m not sure which pet cock go with. If I go with a standard do I have to delete that valve ?

Hey, it's been like 8 years, since I rode motorcycles. Just picked up a 2023 Drz400sm and I've been having issues, where starting it up, it takes forever and I have to hold the ignition button, while it does, which makes me feel like, I'm gonna burn out my starter. Am I not setting the petcock right? Should I put it on prime, when I park it? I had 80's bike's, so I used to always shut the fuel off. I just filled it, for the first time, since the dealership and I used premium, just because I feel like, it'll make it run, smoother. Edit: I'm retarded. I forgot about the choke. Talk about, being a beginner, all over, again.

Hey man not sure if your going to see this but how did you get the fuel line to stay in place I see you have it set in place somehow but how and where can I find it?

I ordered a manual petcock where did you get yours from
