You are the go to guy whenever I even think about doing something to my drz. I’m glad I found your channel man thanks for giving all of us idiots a little help.
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.
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.
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
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.
'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
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
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!
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!

@@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.
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!
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.
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 ?

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

Yes. You can still run factory petcock, but you must cap off the vacuum line. If you don’t, the carb won’t pull fuel.
