Good coverage of an often overlooked part of the bike. When i bought my DR, the previous owner gave me a box of parts and one part was the UNI secondary filter. Like you, he installed filter material in the original unit as he didn't like the effect of the UNI. I never tried the UNI as i have no issues with the way the bike works. I can only wonder if he may have over oiled the UNI and it caused him to have a funky working carb. Years ago, i replaced the filter in my Concours with a K&N and it wouldn't pull through the rev range. Come to find out, the filter was over oiled. Once i put the stock filter back in, problem solved. Just thought i'd pass that along. Cheers from NB!
Very good information Brad, I have ha d no I'll effects with mine but maybe this summer I will try an experiment and really oil it up to see if it impacts the performance. Thanks for sharing your knowledge. Dino
Thank You Dino, another great information video. I haven't seen much if any info on that secondary filter, I appreciate your explanation of exactly what it is and does .
Very good explanation of what this filter does. Not only this applies to the DR-650 but also to another bikes with a constant velocity. Working many years on bikes but some times you hardly take attention to this little piece. Thanks for this excellent information.
Thank you for the additional information, I love it when others add to the story, I have said it before, I am not an expert or even a mechanic so others knowledge is very helpful. Thank you again and I am glad you enjoy the content. Dino
Another great video Dino! Even though Emma's DR doesn't have a hidden trumpet (pre '96), we still watched it all the way through and enjoyed every second of the video! Always makes us really zen!🙋🙋♂️🏍️🏍️
When I spotted the video I thought you may be talking about the secondary air system. My Honda has that filter with a big hose going to the carb. The can was filled with nasty foam. I replaced the foam. Never looked at where the air goes.
Thanks so much for the information a bout the small filter for the carburetor. I had cleaned mine quite often but didn’t no about the little retaining screen as someone had been there before me. So it was not were it should be but it was under the filter. So this time after removing the filter I found the outer retainer and put back on the outside now the filter will stay in place. Plus I cut out extra filter out of a old filter from a old dirt bike filter. So thanks so much for this information. I have been a Auto Tech for 50 years and new never stop learning.
Thank you for the feedback, I was lucky enough to work with some very fine mechanics over the years and all of them loved to learn new things, I think they have a built in curiosity that never gets satisfied. Thank you again. Dino
@@DinosTinkerShedTy for the info on the filter. I bought a 2007 dr bk in 2014 I think it has the filter you purchased,I never cleaned it,now I will im like the rest clean the main filter but not the secondary ty so much,I'm getting on that soon..tks bud.
If not cleaned reports Iv'e heard can be extreme bogging and loss of power. A lot can be said for women's stocking material, I have used that in past yrs on several engines. It acts as a pre filter of sorts, very breathable but stops bigger to medium particulants getting in. I used it on the outside of filters / boxes ect. . Great vid as usual Dino. Thanks.
Wow, what a great tip!, I will have to try that. I have heard the same issues about the bogging as you mentioned. @MOTODANS has said that he has experienced this first hand due to a dirty filter. Again, I love the pre filter idea, thank you for sharing. Dino
Did the TST Industry for LED blinkers when I got home for work. Thanks for sharing all your great videos would have never known were to the get part's.
Thank you for the comment, and you are very welcome. It's fun making the videos and knowing other can use the information makes it all the better. Dino
Love your videos Dino. So calm, informative and nicely made. You seem like a relly cool guy to hang out with and drinke some cold beer. Nice greetings from germany ✌🏼
Great video Dino! I'm currently installing the new Cogent suspension upgrades I recently bought from Bushpig Performance for my DR650. They were great guys to buy from and of course a huge bonus they are here in Canada 👍
Nice one Dino, something that would get over looked i reckon. I fitted a uni air filter ( not like your one ) for awhile but I found it would get dirty around twice as often as the stock one ( enough to cause running issues ) and it actually ended up falling apart after a few washes. I cut it up and have stuffed it into the end of the stock one like what you have done. Been going well since then, have a k & n style in a box like yours just haven't had a need for it yet.
Thank you for the comment Dan, very interesting on the additional cleaning, I think the one I have also gets dirty a bit more often, however I have not noticed any ill effects as of yet. I wonder why that is? Thank you for the comment Dan Dino
@@DinosTinkerShed Only thing i could think of was how it was completely open? Being that open and oil maybe attracts more dirt? I am not sure the uni filter one i have was a bit different to yours basically just a foam cylinder had no plastic end piece so it would just get completely covered.
Hi Dino, have just purchased a DR 650 and watch most of your videos. They are extremely helpful and your delivery is great. You must be a teacher? If not you should be. Have a query I’m hoping you can help with. With the bike on a stand and the bike in neutral, if I turn the back wheel in a forward direction there’s a knocking noise from the counter shaft/ front sprocket no knocking if I turn the wheel backward or if I put it in gear pull the clutch in and turn the wheel. Any ideas? Thanks in advance and thanks for the great videos. Harry
I don’t even own a DR650 (yet) 😂 but I really enjoy your videos 👍 I can see you own the Clymer service manual. Do you think it is better than the official Suzuki DR650 manual ? 🤔 I feel like the official Suzuki manual would mention the secondary air filter, no ?
The Suzuki manuals do have some errors so make sure to cross reference with corrected online versions available in PDF or the DR650 app for Android users.
Thank you for the comment and the question. I do use the Clymers manual most often but I do have access to the factory service manual as well. as Gone Awry points out there are a few errors in the factory manual but there are amended versions available from what I have heard. Even in the factory manual I could not find much more than a part number for it. now it may be in an obscure area of the book that I did not look but I really did not find much on it. Again, thank you for the question. Dino
I will have to look into this. Is it more durable than the standard regulator? Or is the power cleaner? Not familiar with this mod. Thank you for sharing. Dino
@@DinosTinkerShed Yes, it is more durable and will boost your voltage. I run auxiliary led lights on my DR; with the stock regulator the battery voltage would drop to 12,3V with all the lights on. With this mod, it never goes below 13,2V and stabilizes around 14,7V with the lights off. And this voltage is available at idle speed. I bought a FZ8 regulator at a scrapyard on ebay, all in all, it cost me less than 60 €. The downside is you will need to relocate it as mosfet regulators are bigger.
Dino, that replacement filter you added (the green foam) seems to me like a lot more foam than stock, wouldn't it cause a reduction in air flow? I'm sure it would. But I'm thinking, considering the purpose of that airflow, it shouldn't matter?
Thank you for the question, I suppose it could, again, I went another route and used the UNI filter. I believe MOTODANS used a thick foam filter on his and he eventually changed it out, it was an aftermarket filter not a moded stock unit but you may be right. Thank you for the comment and information. Dino
It is strange that my DR 650 RSE doesn't have this secondary air filter. Instead that hose from carburetor is connected to filter box, so it is using the main air filter. I am wondering if using standalone secondary filter would be beneficial.
Hmmm, that's odd. I would have thought the RSE would have shared the same filtration. I'm not sure how adding this secondary filter would impact performance, your bike may be tuned to use the current set up. Might be interesting to try though. Thank you for the information and comment. If you do try tood your bike, please let me know how it turns out. Thank you for your comment. Dino
@@DinosTinkerShed Ive also heard that some people who do the air box mod, drilling holes and no snorkel have had problems with that secondary air filter being too close to the mod and its competing with the extra suction / robbing it causing extreme bogging. Just hear say on forums so just saying, something to think about. Good luck.
Hey Dino could you tell me how to adjust clutch on 1999 Kawasaki bayou 300 2x4? I’ve heard turn the screw forward till you feel tension then back till you feel tension and I’ve heard forward till you feel tension and back 1/8th so please help thanks.
I just remembered I did a video on this. the adjustment chapter is in the description and you can skip to it, I know this is a 400 but I am sure they are similar in set up. th-cam.com/video/Gxew3V3Nv8c/w-d-xo.html Hope this helps Dino
@@jessejones9207 hmm, I have never worked on a 300, so I figured they would be the same. Sounds more like a Honda 50 style with only one adjustment bolt Even with Two bolts, the 400 is very similar to the Honda's I have worked on, only one of the adjustment bolts are actually used forost adjustments. That being said, I would look for an online manual to make sure it is set right. Sorry I can't be more help. Dino
Ciao Dino , è molto strano che nel mio rse del 92 non ha nessun filtro . Eppure monta lo stesso carburatore 🤔. Tu cosa ne pensi ? Un saluto dalla Sicilia 🖐️
Thank you for the question, does the vent hose from the Carburetor lead into the main air box? It might have been a different design that they changed in 1996? Thank you for comment Dino
that's odd, maybe they did not feel a filter was necessary at the time but added one in later with the 1996 SE. Thank you for the information, it is always nice to learn new things. Dino
