Alright, we're going to do a carpe seat on a Suzuki Katana today. Same thing for anything else on in line 4, real similar practices. We got a real problem. Can you see the big gap between the throttle, PM plate and then the adjuster screw? So you can see here's that same Suzuki carburetor there. As we get ready to synchronization, you're going to see that there's a lot that we can do on the bench. Any four-cylinder like this, you're going to have three adjustment screws. So as we started cleaning carbs, I said that we always want to take this and we want to make sure that we're a certain position. Here's a nice picture of that position that I'm talking about. That throttle plate right there. You can see where the arrow is pointing. There's usually three, sometimes five little holes there. Many service manuals will specify to put the throttle plate just forward to that first hole and that'll get you a good baseline idle. What we're looking at on his bike and the thing we want to build a relationship to, he's got that big gap in there. Okay? And his throttle cable has free play. Usually what I'll do is I'll take the throttle cable off and make sure that the cable isn't hung up somewhere, but his cable will sit and flop all over there. So the cable's not holding it open. What in the world's holding that open? Let's look at our possibilities. Could it be that one of these were installed crooked and they're hanging it open? Could it be that this is bent from somebody doing a previous disassembly or something? Because if that's bent, that's going to hang it up. Well, we're really going to go focus on right now. I want to go look at the three adjusters and I want to see if this spring is like severely compressed. Okay? I'm going to go ahead and I'm just going to mess this one up. Let's prove a point. See what happened? Look familiar. We look at that bracket and see that that's off of this carburetor. Whatever the idle one is, the base one. So on the bench on the rebuild, this is going to be a good idea to always make sure that the butterflies will be able to hit against the stop. Alright, let's go ahead and fire it up. Watch this. We just about get the thing to idle just by adjusting that center screw alone. Now you see we're actually turning the actual idle adjustment screw and we have room to go back and board. Let's see if the bolt's on the gauge just now. Listen to that engine and see if you would have guessed that it's this far out of sync. Check out the gauges. Okay, this is the track. It's made for a 90s and it works down. It's one thing we have to do is check the tool. So what we've done is we made a little manifold tool here and what we want is we need your caps because what we're going to do is we're going to take all of the gauges simultaneously and pull them off one vacuum. What's that tell us about our gauges? How off each gauges from each other? Right, so the last time these gauges were checked this one reads one less than that. These two obviously read the same and that one reads two more. So do you give them same for us to truly sync this engine with this tool in its current condition? We have to actually have this one say minus one and this one say plus two. What we're adjusting is those adjustment screws that we talked about earlier here. There's the one for the middle two. We're going to sync these two. These two and then we're going to pull them together. So all I have to focus right now is I'm going to focus on a pair of gauges, dial it in, focus on the other pair and it's a really a back and forth process. What you might see or hear in the video, we're going to go ahead and speed this up. It's sometimes it's easier to just kill the motor, tip the throttle plate to easier access the screw. Alright, let's go ahead and sync this. Alright, you see how we're just somewhat closer? Remember how jacked up these are, right? Yeah. So now we're just going to switch to the middle one and you're going to watch them pull around each other. Where people get into trouble is they're sitting here and they're trying to think about, well should I go clockwise, go counterclockwise, don't think about it. Just start turning the screw and once it just starts moving the right direction, keep going to the right direction. I'm not going to start the idle back now. Alright, let's prove a point, let's focus that camera in on that throttle stop. Look at that, it's the craziest thing. We can actually use the idle now. Yay! Let's do a little checklist quick here. We want to make sure that the engine's fully warmed up. We've got a fan going across the engine because it's air cooled here, that's an important tip. Not to overheat it and then we want to do what we did is we synchronized our tool so that we know we don't have any issues there. Then we go ahead and get it hooked up and you saw how to start turning them, it's nice to do pairs and then try and pull them together. We were actually really good on this side, we did next to nothing. We just had some whacked out stuff because of people messing with screws there. And it's still, it even ran, it didn't run terrible, you're the owner, didn't you say it didn't run too bad. But man, this is how you do it, fully right. Another thing, did you notice how every time you make adjustment we flip the throttle, don't forget to plug any vacuum lines like off the fuel valve or what not, otherwise all the work you did is going to be wasted.
