    Great!
    That means it's still too rich.
    That there is still a rich stumble in the 3rd position corroborates that there is extra fuel coming from somewhere. Possible sources are a worn emulsion tube, larger than stock pilot jet, high fuel level (due to incorrect float height adjustment or faulty float system), drilled slide, cut slide spring, clogged air bleed jet, stuck cold start enrichment slide, and/or additional preload on the slide spring.
    That's good.
    The cold start circuit is supposed to take care of that until the engine is warm enough.
    If it's a Uni UP-123, those don't come oiled, and don't filter very well even when oiled. I recommend adding an oiled foam sleeve or replacing with an oiled foam unit.
    It should be replaced if it's been smashed flat as they commonly are.
    I don't think the wetness means a leak (actually the contrary may be true). It's probably not necessary to replace the cover unless there is visible damage and/or testing reveals a vacuum leak.
    In my opinion the tail of a caliper is not accurate enough as it's difficult to assure that it's normal to the gasket surface and there is not enough overlap to the float.
    What year is your DR650 and what code is stamped into the existing emulsion tube? Also, does it have the Mikuni square in the corner of a square symbol stamped in it?
    09494-00884 is what I sell for '96 & up DR650s.

    Regards,

    Okie doke. Got a few hours in the shop tonight.

    Filters oiled (lightly) and installed.

    Tach is good to go. Left the fuel mixture screw and idle as is. Did a 10 mile jaunt. Finally have some numbers to play with.

    35mph twistie road, I'm in 3rd at 4800-5200 RPM. 5000 seems to be my average.

    Behind a car on a 50mph road I'm also riding at 5,000 RPM.

    35mph road with straights I click up a gear and ride at 4200RPM.

    Overall, my go-to rpm is 5,000 or just a tad under. Is that really racing this motor?

    Got back to the house. Engine was idling at 1,700 RPM. Fuel mixture screw was a tad over 3 turns out. I lightly seated the screw, backed out to 1.5 turns, and set the idle to 1500. Went for a quick half mile loop, no popping on decel, but I'm not sure if I took a hit in power or its just my mind messing with me. I'll have to take it for a longer ride. But, it idles fine and throttle seems to be instant just like before.

    We'll see what the mileage is out of the tank.

    Now that you have a tach..
    did you set the screw by ear and it happened to be at 1.5 or did you just go to 1.5.

    Scroll down and follow " how do i adjust the fuel mixture properly "
    https://procycle.us/info/questions/dr650/fuel_system.html

    Motolab may have instructions as well, but i have no idea where on his site to link to if he does.

    Schmokel,
    What tach did you get, and do you have pics/video of the install? I'm in the market and schmokeling between a full computer or simple tach.

    Just went to 1.5. The reason being, I looked all over to find that link you posted on my phone, but it was a pain in the ass to find.

    I knew you mentioned something a few pages back, but again it sucks looking through my phone. I may have to retackle this again.

    Directions say there is supposed to be an hour meter and clock, but nothing happens when I hit the button. Broken maybe? Iunno. Tach works good so run it.

    @motolab also, when I initially set the idle to 1500, what should the mixture screw be set to? I simply started at 1500rpm with the screw to 1.5 turns out.

    Cheers.
    I'll add it to my links i post if and when someone else asks.

    I'll be honest, i like to post links to the sites of the guys that hang out here if i can and it also helps people in case they need to buy something.
    You guys that hang out here and run a small business need all the support i give in any way, no matter how small that may be.

    It's appreciated what you guys do.
    I prefer to support the little guys, rather than search for the cheapest price on google.

    I think it's also criminal, not just a ticket. I'm always nervous in VA since I've read that the fines are huge.

    It's likely a matter of perspective. You seem to like to ride using a gear selection that is at least one too low for your given rate of travel. Personally, I think a broadband (sustained) use of 5K rpm on the DR650 is too high (and I say this as someone who has a 14T CS installed, with the attendant effect on average engine speed.) Others may disagree, but here's the thing that matters: It's your bike and your riding experience. If you can make peace with the resultant fuel mileage, and your bike continues to run well, then that's your style and that's that. Maybe there's a proper sport bike in your future. They're much more suited for your need for a braap braap fix than is a senescent dual sport.

    The way I look at it is this: an engine has, let's say, a billion revolutions before it starts burning oil. I short shift to keep my RPM down and to extend my motor's life. I got to about 60k miles before I started burning a bit of oil. I'm guessing Schmokel will be burning oil at 30k and blaming Suzuki. :dirtdog

    Ok guys, I'm proud of myself. I just finished my first solo tire change. And it was the rear to boot! Dead T63 removed and new S244 installed. Only slight rub is that I'm pretty sure the bead isn't all the way seated all the way around.

    I aired it up to 70psi and that caused a pop, but it doesn't look even. Rode it around the block at 70psi, then aired it down to 23psi and rode around the block again. Got up to 35mph or so.

    Got any tricks or do I just need to go ride it more? Faster maybe? Or lower pressure to cause more carcass flex? Something else entirely? Don't worry about it?

    Bought a 5.3L tank from Justgastanks July 27 and was notified that it was on backorder and would be shipped late August. No biggy. I wait a while since shipping to Canada is always slow, but no shipping notification came.

    Nothing showed up in the mail, but the order status was listed as complete. I contact JGT and they said I never responded to say I still wanted the tank. Wtf lol Of course I do, and they didn't actually ask anything.

    They say it'll be shipped in 7-10 days, then follow up to say it'll be shipped late October. I'll be getting the sled ready by the time it arrives! Oh well.... Hasn't caused too much of a hardship for me...

    My rant for the evening

    I can't imagine why the delay. There is no availability problem with the 5.3 tanks.

    Find this line and follow it around the rim, that'll tell you if the tire's seated. If not seated, find a dirt road and go for a ride or air down, unseat tire, lube and try again.

    Yeah, the lines aren't even. I'll see what I can do with it in the morning. Hopefully I don't need to take it back off the bike.
