    Yeah I was moving the throttle all over the place to keep it running. I rode it around the yard a little. It's closer than it was. Gas isn't flying out the back and it barely smokes anymore. The rings seem to have seated. 35 is the smallest jet Keihin makes so if this is too rich I'm going to have to get rid of these carbs. I don't understand how it could need a smaller jet. It came with 48s jetted to a 350 2-stroke. Would a 350 2-stroke pull that much more air than a 1000cc 4-stroke? :dunno

    I'm hoping it was just the mic, but why did your bike sound like a chainsaw?

    That was crazy. WHat were the random numbers, again?

    It sounds like its crazy advanced and running on one cylinder or something

    You should just have to figure out hte idle jet right now

    It does sound a lot like a 2-stroke but that video doesn't really show the sound. If something gets too loud it make it into a garbled mess. It's definitely louder than I want it. I still need to put a spark arrestor in the muffler so I'm hoping that will dampen it a bit.

    The gauge is the air-fuel ratio but since I was opening and closing the throttle it didn't sit in one spot. 14.5:1 is efficient but there's a peak torque somewhere around 13:1. I'm hoping to be able to dial it in that closely but when it's this far off it's hard to figure out which way to go.

    I found a guy on a XS650 forum that had these carbs. He went through 2 months of screwing with them, swapping the needles twice, but he said it was like fuel injection when it was dialed in. He had a 40 Slow Jet and a 125 main jet. I've got a 35, 40, and a 38 coming in the mail. The main is a 160.

    Bill, the guy that helped me the first time, has plenty of main jets but he's been in the hospital. He knows a lot more about these carbs than I ever will, that whole setting a land speed record thing ya know?, so I'd rather wait until he can help me.

    Of course, I've played with these carbs quite a bit anyways, moving the needle up and down and swapping jets, but I haven't gotten it running consistently. You might not know this, but I don't know anything :confused I think maybe if I hold the throttle open for a while and let it warm up....

    Anyways, new project.

    I made a big underseat toolbox then realized I needed a wrench to get the seat off. Yeah, it's kinda like locking your keys in your car :doh

    I chopped a piece of square tubing in half and made a standoff for the sub-frame. This way it'd be in line with the back rail on the solo seat's luggage rack.

    [​IMG]

    I welded the keeper to the seat.

    [​IMG]

    I mounted one of the hatch latches like I used to hold the battery on that plate.

    The original mounts had nuts welded on the bottom and the seat bolted on from the top. I ran a bolt up from the bottom instead and held the seat tabs down with a second nut on the top. The holes on the seat were ovals so this made sure the nuts were in the right spot. I welded the nuts to the seat, pulled the bolts, then drilled the threads on the top nuts with the tightest drill bit I could find.

    [​IMG]

    All I have to do is unbuckle it at the back and pull up on the seat. I can lean back standing up on the seat and it doesn't move at all. The posts take all the weight and the latch just has to hold the seat down. I think it'll hold up.

    The best part is that I didn't alter the original mounts. If my latch fails I can still run bolts in from the top the way it was before.

    [​IMG]

    I didn't weld the latch because it'd ruin the powdercoat. As it is, it blends in. Hopefully crooks won't notice a way to into my tool box.

    I'm planning on making a new dash when I'm not broke. I'm aiming for 2020 :D For now I'm building the cheap stuff.

    I never felt good about my ignition switch. Anybody could pull two wires and take the bike. Of course, I use the rotor lock that Jenna gave me...usually :augie

    Anyways I want to hide it somewhere.

    [​IMG]

    I found a vending machine switch on Amazon. Maybe since it doesn't look like a normal switch a crook won't think to yank the wires attached to it and tie 'em together.

    The key doesn't stay in the switch like on a car or bike. How much sense would that make in a vending machine? So I turn it, pull the key and put it back in my pocket. Neat! I won't lose my keys!

    [​IMG]

    I also mounted an outlet from my favorite sailing website. It's made by a company called Blue Sea Systems and it was $9. It's a lot better than anything I could find at the auto parts store. The lid actually stays closed. My old one kept opening and rain would get in. I bought two of these and I'm planning on putting another one on the dash. That oughta take care of jacket and gloves.
    Gotta make that Enduralast earn it's pay. :pierce
    I also left a spot for another switch if I find I need it in the future.

    [​IMG]

    Those pink hoses kinda stand out. I guess I'll tell people they're my breast cancer awareness carbs :D Or maybe I'll just get new hoses.

    It's hard to get your hand in there, even from the other side. I guess they could yank the whole plate out :dunno It's safer than anything I could come up with on the handlebar in any case.

    I think my best defense is going for the 'this bike isn't worth stealing' look :lol3

    The wiring will have to wait until I get the dash put together. I've been too busy failing Calculus tests to do it.

    Bill's been too busy having near-death experiences to fix my carbs. I told him I was holding him to that 'not dying before he tunes my carbs' promise. :deal He should be out of the hospital this week.

    I had some 22.5s but his meter told him that he was lean on idle. So now he needs another 25 jet as there was only one in the box.

    +1

    I'd also like those jets back ... I believe that there were some 175's in there ... I wanna try them in BB. You got your O2 meter workin?

    Let's beer. I'm gonna sell the /5. I took the Dobber out on Saturday for a 30 minute romp, and I'm still wearing the grin. That bike will get up an leave your ass if you're not careful. :evil

    Looking for fuel
    Just upgraded to 1000cc from 800, using a 145 main and 50 pilot?? Runs ok. Same set up when it was an 800.

    Yep it's got some 175s in its. The A/F gauge is working great. I'm running right around 12.5:1 at idle with 22.5 idle jets in Mikuni VM34s. I haven't started the synching/idling process yet but I doubt I'll have to change the idle jets. I put some 160 mains in and I'm still running a tad rich when I open it up. Makes me think this new intake sucks. It ran fine on 180s though so maybe you're running way rich on the Dobber.

    I can't ride much until the bike shop opens tomorrow since the oil pressure switch is pouring. My left boot is now 5 shades darker than the right. And waterproof.

    @Wydell: It makes sense that you're jetting wouldn't change as long as it's the same intake. Bigger jugs don't need bigger jets.

    I'm next in line....been waiting since Blaine got his miks. I'm still having a devil of a time starting the bike and I can't figure out if it's lean or rich? Going up or down on pilot isn't changing it.
