That’s the idea! I searched for these videos myself and never found ones I liked, so I decided to make them myself. Thanks for watching I appreciate it.
Hey Link, I really like your videos they are great and really helpful. I have a huge crush on DRZ's but here where I live (Finland) you can't buy new ones only used ones and that kinda sucks, the newest one I found was 2006. But in the other hand these bikes are pretty reliable so that might not be an issue. Next summer I'm going to buy one forsure! Keep it up man, you are the best! 💯
Great vid man 🍻 thanks again for an easy vid to follow, there is only a few others on this and they are on Australia bikes which have a diff carb and vacuum setups
Very nicely done and detailed. Your channel is exactly what the drz community was missing on youtube. Did you really notice any real world difference doing this? A video on the drz locktite fixes would be epic! Would also save your countershaft from premature failure
Thank you Max! And honestly I didn’t ride it very much. I almost immediately swapped to the FCR39 Carb and was busy filming that. But after I rode it all together it sounded and ran fantastic. I appreciate that. And I hope I’m offering something that helps people out there.
For the guys removing the pair valve and installing a Yoshi pipe and header Buy a pipe for the older model of drz without a pair valve system. They actually shaped different to clear the valve. Older style pipe looks cleaner. I found out the hard way.
I got a 2021 and take it from me. Get that vacuum petcock off there ASAP. That sucker was leaking gas by. I got a Pingel Manuel petcock and it’s perfect. Very heavy duty.
Yep. It’s gone. Installed a manual one. Did it a couple months ago. Didn’t get a pingel. But those are prob the best ones out there. Thanks is for watching. I appreciate it!
Awesome! Just got a Keihin fcr39 for mine also. I’m cleaning it and replacing gaskets and rejetting. What kind of petcock did you get, what bike did it came off of? Or is it a chinese part like the fcr carb?
This is the petcock I used. Worked perfect. The fuel nipple points tout instead of down, so just loop the hose and you’ll be good. www.ebay.com/itm/265344699648?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=8tjRy9AxRMi&sssrc=2349624&ssuid=fNTislqYQny&var=&widget_ver=artemis&media=COPY
Nice video! Looking forward to your carburetor video. Where did you pick up your carb? I have been thinking about doing the same but the price for the carburetor is steep
Got an FCR39 slant carb off eBay. It’s a copy. Not an authentic. But the quality actually looks really good. And it came with a great assortment of jets etc. and it freaking rips.
@@georgespoirier481 yea, the genuine article is for sure better. This was kind of an experiment. For $150 what can you make. And so far, I’m impressed.
Hey, I love your DRZ Build series, helps inspire my build forsure. I was just wondering why you did this or what the benifit is of removing this PAIR valve?
Are you replacing the petcock because of the carb swap or just to eliminate the vacuum style one? Looking forward to the carb install. You might try taking your sharpie and blacking out the vacuum cap even though that is getting replaced soon. One question, do you have the baffle in the muffler? I would like to change my exhaust, but that is a bit louder than I want. I guess I'm getting old.
Replacing to get rid of vacuum operation. I’ve already replaced the carb and it’s all together. It rips! And yes. It has the baffle in it. Sounded a bit cleaner that way. Thanks for watching!
@@NittoSmoke770 the vacuum Petcocks are known to be problematic. And fail/ leak. So I went with a standard gravity style. Plus, the FCR doesn’t have a vacuum port like the CV carb. I could have used the vacuum port on the cylinder, but this was cleaner. And hopefully more reliable. Thanks for watching!
Weird mine didn’t come with that on there. Maybe 2018 DRZ didn’t come with it. So the knock off FCR39 slant is worth a try? All I’m doing is wheelies really. How’s the petcock ? Every thing in my bike has been modded besides my carb an petcock. If you think it’s worth it send me sum links brotha. I’m down to try it out. I’d want the exact links from you tho cause I just have bad luck with buying knock off stuff. Great vid brother. Keep it up.
I’ll shoot them your way. I will have videos coming soon. Filmed and ready to go. Detailed install and all parts used etc. the slang Knock off freaking rips. Blast up the front wheel throttle only on 1st and 2nd. Never did that before. Thanks for watching, I appreciate it.
@@linksgarage1985 haha wheelies are addictive. I learned on my grom an pitbike. Just remember to keep that foot on that brake no matter what. Kool. I’m subscribed so I’ll be waiting on that vid. Much appreciated 🤙🏽🤙🏽
'Passive Air Injection'. Did they have to put that on the bike to make up for the way that they suffocate the engine with the stock muffler and spark arrestor/emissions crap? Or, something else?
The Pair Valve is to passively "Inject" fresh air into the exhaust system at the exhaust port, to cause ignition of unburned fuel vapor *before* it leaves the exhaust pipes, or to thin out the mixture with enough air to pass emissions. It also causes popping and backfiring on deceleration when you jet, and exhaust it.
It is. It needed to swap the petcock in this step. However I changed carbs to a FCR39. There is no vacuum port. The vacuum petcock can fail. If there is no vacuum you get no fuel. A gravity or a standard petcock, will always let you get fuel. Plus the vacuum petcocks leak. And the benefit is, decor pop. I explain it briefly in the video
How much would you say doing the pair valve delete got rid of the annoying decel pop? I’ve done all the mods and this is the last thing I have left to do. Full aftermarket exhaust system on mine.
Having done secondary air deletes on R1s/zx9rs/R6s etc, not 1 has benefited from it. It doesn’t solve popping etc. 90% of popping and backfiring is down to ovaled emulsion tube/s on carbs or airleak.Secondary air is emission related
Question The pair valve create the vacume needed for the carb? You talk about going to a gravity feed. Is that needed. I just did it and the carb seems like it is not getting the fuel needed
@@WillMein-ho6hi for sure. Just cap off that little vacuum port from the line you disconnected from the pair valve and fuel will pull. (A truck if you were ever in a jam, you could probably run on PRI or prime) in this setting fuel continues to flow regardless if vacuum. Let me know if you need anything else!
@@linksgarage1985 I live in NV and my 2021 was originally from CA so it does have that rear canister. Can I remove it while doing the pair valve removal or will that screw something up?
Just got a 22 DRZ sm 5k miles bought it with Yoshi R2 which is the only mod for engine. Noticing in high RPM it surges. Previous owner ran 93 octane, i just filled it with 87. I just found this video and going to do this and replace petcock. Do you think these 2 mods will help the surging?
Right on bro, I'm REALLY appreciative of your help, .... Truly! I'm a newbie to this bike so it's awesome to have your channel. Is there different sizes of jets and what would work with my stock motor?
@linksgarage1985 Thanks i just bought a 23 drz400 sm,my background is superbikes, ive changing lights,i noticed the muffler is really restricted, are the cheap exhausts on ebay any good ,great video thanks
I did the removal and now my bike won’t run It starts on full choke but when I close the choke it dies I completely removed the part from the engine block and used a bought block off plate. If the seal wasn’t tight on the block off plate, would it cause air/fuel ratio to be off? Or if the petcock pipe wasn’t blocked off correctly would cause the same ?
@@linksgarage1985 bike was perfectly working before I removed the pair valve. I put the pair valve back on and it still wouldn’t start unless it was on prime. I took the pair valve off and installed block off plate But instead of capping the end of the that three piece connector for the vaccum I put the vaccum line from the carb straight to the petcock that way I don’t need to block that part off. Anyway it’s still not starting unless on prime. Will be testing if there is any vacuum pressure . 400SM 2019
@@arrrahawk I bet it’s not getting fuel. Something isn’t right with that part. That’s why it will only run in prime. Because it’s bypassing the vacuum. I’d swap in a standard Petcock (I did this in my carb video) and it’ll work perfect.
@@linksgarage1985 thanks! I’m going to try just adding the caps on the 2 lines while leaving everything else on the bike - just to see if stopping that bit of fresh air into the header makes any functional difference - I’ve got a jetted Yoshi RS2 pipe/header and I’ve heard rumor from some DRZ owners that disconnecting the PAIR system reduces pops/backfires….I guess we will see. 🤔
@@linksgarage1985 are you looking to adopt any children I’m just a 30yr old no dad learning on his own lmaooo jk man thanks for the intuitive, visual and descriptive videos
