    Scotty!! Let us know how your doing when you get a chance. You'll be purring/pulling before you know it. Is a great feeling and I want to see you get there.

    That's exactly it. Is been decades since I've worked on a 70's bike. EPA was all up in everyone's business. Thanks for the refresher course. That does clear things up quite a bit.

    Thanks amc. It's all coming back now. If they're behind the slides they obviously aren't getting fuel. The air only screws are commonly referred to as mixture screws despite the fact, just to confuse people...... Or is it so people don't get confused..... Things that make you go hmmmmmmmmmmm?

    Xschris, do the pre 80 bikes also turn the mixture screws in the opposite direction? Never owned one before 80. Still learning every day. Also, could he be missing a washer? Long shot, but bikes can run lean with low fuel in the bowls. Not lean enough for this condition. I don't think it's...

    Check the cable while moving it around, too.

    Good job, man. You are so close! Yes slightly is ok. You will need to do it again when it is fully warm after a 20 minute ride to hone her in. Some of the earlier bikes are different; I think you should try turning the mixture screws clockwise to richen the mixture. Or begin by going for the...

    Hey, wire. You mentioned you sold some things to Alex. Did they include the side panels that look like check marks(Matches Tank, one side says maxim 400)? If so, I'm gonna ask him. Thanks -ATX

    Don't know if you've tried this, but make sure the throttle cable isn't binding on anything, too. Even move it around while moving the handlebars. You're doing everything right; it won't be long. Make sure the boots are tight. Spitballing here. Do you have a manometer? If you put your hands...

    Sorry, didn't know you had them apart I guess I meant separated, but I see you've synched them. I totally understand what your saying about understanding. Can be confusing at first. Have you sprayed wd-40 around the boots?

    You should look at a diagram whenever you get a chance. I know it can be intimidating, but someday you'll be giving advice. Until you take it off and apart for the first time, a picture is worth....

    Scotty! Ooohhh. The idle knob? It controls both carbs. Is that what you meant? That knob will be the last thing you adjust to get your idle right after you dial in the mixture screws? Where are you starting them? Try 2.5 turns out after lightly seating.

    There's another knob/screw under the throttle shaft (SOHC) that controls idle only. It's a flathead screwdriver on the DOHC, and on the side. Almost there!!

    1980 XS400 revving problems (videos)

    amc49 nailed it on this one. I listened to the video as well, and it's sounds to me like she's only firing off one cylinder. I think you should touch the exhaust and see if one of em isn't getting warm. It's could be something as simple as a bad wire from the coil. Check for spark, man.

    Looking for some advice

    Hey, Jimmer. U said you are looking for something easy first. Make sure your exhaust is not clogged. I've seen rusted, also hornets nest show the same symptoms. Place your hand behind the exhaust and feel the pressure of the exhaust. It's pretty easy to tell if one it's pushing harder than the...

    I'm afraid they are correct. If the engine is sentimental it could be saved. If you're looking for a challenge it can be done, however, it would save a lot of trouble if you were to spend a couple hundred on an engine(with compression). If it has compression you can get it running. Good luck...

    1981 idling issue

    if you have not done so already, be sure to check your idle adjustment screw. the one with the spring on it, as well. This opens and closes the butterflies and only controls RPMs. This should be one of the last things you do after fine-tuning is complete, but there's a possibility it could be...

    1981 idling issue

    Howdy, Jwin. As AMC mentioned hanging RPMs can be the result of a vacuum leak. Your mixture screws can create a lean condition which mimics a vacuum leak. You could start by richening the mixture or setting the mixture screws at two and a half turns out from being lightly seated.... do not over...

    Hey, Raymond. At your current status this information may be a little late, but could possibly help you or someone else in the future. Years ago, an old Harley guy showed me an adapter tool he made out of a spark plug (with the ceramic end cut off) and a grease gun fitting welded to it. He said...
