Finally used a sight tube today and set the floats. They were not off my much at all, like 2 mm. I guess that means the float vavle assembly is working correctly. I have to go to a family function, so Ill give another update tomorrow.

OK guys, like I said, I hooked up the sight tube and finally got my float levels set properly. I went to fire the bike up after sitting for over 5 weeks and it started on the second kick. It didnt take but 10 seconds for my left cylinder to start gurgling and farting. I put my hand over the left pipe and it felt like it was barely pushing anything. Remember, this is and always has been my problem cylinder. I am seriously done with this machine. I have done every single thing more than twice and nothing helps. Im pretty damn certain my problem is in the fuel mix, because all of my eletrical is spot on. My left plug was black and sooty after only 20 seconds of idling. Mixture screw was half way out as well. Someone please say somethign to make me feel better.
OK, Josh, you've eliminated the float mechanism as a problem, since the sight tube will run high if the float valves aren't sealing no matter what level the floats are set to. The problem preexisted the ignition change and you're getting spark, so I think it's safe to rule out ignition. There was no defect in the pilot nozzle, fuel screw or fuel screw seat that I could see in the carb set I gave you, and the intake air jets were clear; but nonresponse to the fuel screw points to a problem in the pilot circuit or the choke seal. Take a close look at the float bowl gasket; is there any blockage at the outlet of the pilot air intake? What happens when you remove the right side air filter? If all else fails cut a piece out of a plastic bag the diameter of your old choke plunger, stick it on with weather strip cement, and see if that clears things up. Gasoline will eat the plastic up and make a mess after awhile so don't run the bike on the street that way, just stick it in there long enough to test. Apart from that I'm stumped!

Guys, It was my compression all along. Im only pushing 90psi in my left cylinder. Time for a leakdown test. I assume its in the valves somewhere and not through the rings. Looks like round 3 of tearing this thing apart.

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.
