SV650 Carburettor Synchronisation, using vacuum gauges. Thanks to AJ for supporting. I really enjoyed this and was surprised at how little time was needed once the gauges were set up.

It might be worth mentioning that the front carburetor is "fixed" and has no adjustment. The rear is the one you sync to match the front with the adjuster screw. Thank you for the video! As usual, simply brilliant!

This is a basic sync. To truly synchronize your carbs you need to follow my 7 step method. 1. Remove carbs from bike 2 . Use a wire gauge to set the throttle plate gap using the throttle linkage adjuster screw. The throttle plates should be set to be open the same amount( use a piece of coat hanger wire if necessary, between carb wall and throttle plate, adjust until Plate to wire contact is equal in both carbs). 3. Then drill out the brass plug that is protecting the pilot jet screw located on the base of each carburetor, right next to each float bowl. Be careful not to drill too deep, use about 1/8" bit and stop 1/4" - 5/16" deep, use a screw and some pliers to remove the brass plug. Underneath you will find the Pilot Jet Screw (Idle Jet). 4. Install carbs on bike and get running again. 5. Put your vacuum gauges on and sync using the Pilot Jet Screw instead of the connecting linkage (the linkage should already be set to provide equal throttle plate opening). Sync using the "lean drop" method to get the best idle rpm. 6. Once you have these things set perfect: correct float level, clean jets and passages, throttle plate openings are exactly equal, pilot jet screws are adjusted to achieve highest vacuum, stable desired RPM, and both cylinders match. 7. Then you apply vacuum gauges again, rev up to 2500-3000 and if vacuum is still uneven adjust slightly with linkage on side of carb( You will find vacuum to be uneven on some bikes due to difference of cylinder cooling, especially an SV). That is the ultimate tune without going into pilot and main jets, jet needles, needle jets, air bleeds, slide mods, etc.

@@fulesmackofule you don't need it anymore once removed. It only covers the screw to prevent adjustment. The first time you take your bike in for this service they may or may not reinstall a plug depending on dealer policy, most of the time I see it left off by factory service techs.

It also prevents losing the adjustment screw if it ever unwinds.
@longobardir9 ай бұрын
@andrewoshea35 that's what the spring is for, keeps the needle from loosening. The plug was mandated by epa, older carbs didn't have them. They were added sometime late 70s or early 80s to keep people from adjusting. Bikes are set with lean idle for emissions.

I cannot locate what it connects too. I disconnected the wires there to change the cylinder head, Did not take pics as I don't have a magic camera. Could you help me please??

Hi Tamsen. I have a 2006 SV650S and its idling high at time, not always. I would stop at a light sometimes and it would be at 2.5k RPM and other times its normal at 1.5k. I have adjusted the idle screw, changed spark plugs, air filter and oil. Not sure what else could be causing this as its not happening all the times. I can give it some gas with the clutch off and sometimes it will drop to 1.5k pretty fast. Any help is appreciated.

You have to connect the vacuum gauge to the carb, so also connecting it to the tap would possibly mess up the reading. I just sucked the end of the tube until the tap clicked open, folded the pipe to seal it and held it there with a small clamp. A clothes peg or bulldog clip would probably work just as well.

Hey, I hadn’t ridden my bike for 6 months- due to being unwell, the first time I fired it up, it took 5/6 goes with the choke on full, after it was sat on the driveway idling, fuel poured out of the overflow pipes. I think because it had been sat so long, anyway, after running it a few more times, that has stopped completely- so maybe there was a slight flooding effect, a bit of grunge pulled through the tank etc. Maybe the bike just needs to be run for a bit if it’s been sat a while? Otherwise, I would run it, wait until you smell the fuel, then lift the tank (I have done a video on this if needed) and follow the pipe from the tank, look for split pipes or weeping seals. See if you can see any drops of fuel to give you an idea of where the problem might be. There is an idle adjuster if it is revving too high when idle (again there is a video on this) or it could mean it’s time to look at the carbs- you can do it yourself or send them off to be cleaned (usually ultrasonic cleaning makes them come up like new) I hope this helps- let me know how you get on xx
@fulesmackofule2 жыл бұрын
It was useful, but as for a starter, i am just wondering what tools I would have to use (order) to do everything. I assume, for a first time synchronization, I would have to remove the radiator in the front to access that point where you already preinstalled the tube (what diameter?) for easier access in the future. Can you leave the hose there without plugging in the hole for dirt protection? It would have been nice to see the right points on the carburetor where you have to put the hoses on. I would have liked to see the whole process of removing the seat and lifting the tank. Can I leave the tank hose on? I saw another video where someone removed it totally and used some hospital kind of dripping bag. Well, I might be a bit freaked out, but I think it has to be straightforward. By the way, can you feel or hear that when the cylinders don't get the same amount of air/fuel ratio at the same time? Thanks.
@francois8956 Жыл бұрын
Hi, You can find the same vacuum gauges on Amazon. For the extension hose you can use 5 or 6 mm. Don't forget to close the hose with a bolt or something once you finished or you gonna have some air leaks. The hose goes on the bottom right of the carburetor. It's not easy to access you either have to remove the carburetor or as she said move the radiator. Good luck

Eskimo doodle i believe what you are referring to is actually the water drainage from the tank (from the fill opening). This will.connect to the "T" piece which also drains away the overflow of the coolant reservoir. These two together will drain away on the right side of the clutch cover, right between said cover and the frame.

@TamsenCooper7 жыл бұрын
Hey, sorry if it wasn't clear, just to recap at 1:53 I highlight where the synchronisation screw is located. At 2:58 is how to read the gauges (and that you want both to read the same to ensure the same ratio of air to fuel is going to both cylinders) At 4:07 AJ is adjusting the tap to reduce the fluttering effect of the needle on the gauge. At 4:46 the adjustment screw is pointed out with the gauges in shot. This can be tightened or loosened and will affect where the needles point on the gauges. The idea is that they are both showing the same reading as it did during the video. I hope that helps. Thanks for watching.
