Sure, Josh. Remove the caps. Set the range on the meter, join the probes, and zero the needle if it's an analogue type. Then stick one probe in the cap and one probe on the point that screws into the wire.
The pipes aren't the problem, Josh. The fuel screws aren't controling the mix, and that often happens when the float valves or the floats themselves are defective or out of adjustment, the choke plunger isn't sealing, or the pilot jets are incorrect size or series. The same thing has happened with two carb sets and two choke plungers and you indicated that pilots of the right series were in there, so I have only three suggestions left. Check actual fuel level with a sight tube, try stock pilots, and, since the PO also had this problem, you might check the list of components above for things you kept from the old carb set (like floats) and swap 'em out.

Dick, what size plug do I need to fit my drain screw on the bottom of the float bowl? Do you perhaps have a picture or link of what I need? Is the plug a push in or screw in? Thanks! I will slap the stock pilots in again after I use the sight tube.
Get a tapered rubber plug with a 1/4" small end; just cut it back till you have a snug fit in the drain plug hole without pushing it in so far that it blocks the main jet. Drill the plug out, slick down a piece of hard plastic tubing with 3 Bond 1104 or Yamabond #4, and shove it through till it's flush with the inside surface of the plug (small end). Stick a piece of clear hose on the tubing, attach something rigid to the outside of the hose to keep it straight while you check level, and you have it.

No updates yet. I have been really busy with work lately. I still need to go to the hardware store so I can rig up a sight tube. Also, Im going to submerge my floats overnight to see if they have any leaks and im going to take a look at my float needle seat to see if there is anything in there thats causing the needle to jam open. I will report back as soon as I can. Thanks!

This may be stupid, but I always check the easiest things first...... have you checked your spark plug gaps? Maybe that 1 side is way off. Maybe you can try indexing your plugs so that the gap faces the intake valve. I don't know if that's gonna help anything, but hey, at least then you can rule that out.

Roger that. I submerged the floats last night and they did not take on any gas. I pulled the float needles/seats and they looked fine. There seemed to be nothing out of the ordinary going on. Float height was at an even 25mm across the board. Im going to try to make it to the hardware store today to rig up the sight tube.
there could be a small burr in the needle seat. make a q-tip with oooo steel wool. spin it in the seat to remove any burrs. others have used this method with good results.

joshua: The regulator/rectifier unit I got from Mikes PMA has closer hole spacing than original. Are we supposed to mill the holes to fit?
Jun 7, 2017 19:25:58 GMT -5
joshua: My bad. I found the bracket they supplied to mount the rectifier/regulator... Uh oh. How is this meant to work? Which way is it meant to mount? Looks like I have to use some spacers or something. Good instructions would be nice.

craig8johnson: I'm checking the charging system. I'm afraid I might have fried the last battery. With the solid state regulator (after market) what should it be charging at. The book says, I think, 15 volts. I'm hitting 17 when revved. Is that too high?
Jul 11, 2017 18:06:19 GMT -5
gggGary: Yes 17 volts is too high, about 14 volts is max, sounds like you don't have the right regulator or it's wired wrong.

tt650: Trying to breathe life into a 1980 that's been stored (indoors) for 25 yrs. Air filters are dry rotted. Have cleaned carbs but she only runs briefly on choke then stops. Need jet setting info and other ideas that might help her idle and rev.

trix13: Hey everyone! New to the forum and am fighting those gremlins!! New charging system, ignition switch, coil and fuse box. Resistance is higher than normal on the ignition pick up so I'm trying to find one. No such luck yet.

trix13: Also, even though all of my connections are clean, I cannot seem to find out why , when at higher rpms, I hit the signals and the rpms pulse with the signals...hahah. same with the brake light. I appreciate all input!!

louisvan: trix13 - I had a problem with my 1975 SX650. When I got to highway speeds, the engine lost power. The problem was in the connectors. At a certain vibration and the wind pushing on the wiring loom, the connector lost continuity. A bad crimp to the wire.
