The reistors were there to eliminate noise..like the whirring sound you heard with the old tube type radios. Then came along resistor plugs and different wire ends.
Trust me here..I have 6 bikes and all 6 have 1/8 brass rods replacing the resistors..done and never to be a problem again. No damage will result.MY BIKES..1977 GS 750 B, 1978 GS 1000 C (X2)
1978 GS 1000 E, 1979 GS 1000 S, 1973 Yamaha TX 750, 1977 Kawasaki KZ 650B1, 1975 Honda GL1000 Goldwing, 1983 CB 650SC Nighthawk, 1972 Honda CB 350K4, 74 Honda CB550
NEVER SNEAK UP ON A SLEEPING DOG..NOT EVEN YOUR OWN.
I would rather trust my bike to a "QUACK" that KNOWS how to fix it rather than a book worm that THINKS HE KNOWS how to fix it.

Ink pen springs and brass ( or HEAVY guage copper ) and make new resistor replacements the same length as the ceramic ones.MY BIKES..1977 GS 750 B, 1978 GS 1000 C (X2)

Ok guys,
all went well replaced the caps checked spark nice and blue and you can just feel the strenght in it, bike fires up runs again 10 secs and died out. I removed the plugs they were wet and black. I cleaned them started again ran for 15 seconds and died. Tried starting it again with full choke no throttle at all and it backfired really loud. It has never backfired before.

Is it 10 seconds of strong running and a sudden death, or is it sputtering out?
Do you have extra plugs? If so you should use those to check for spark again immediately after it dies. Wet and black sounds like fouling to me. Do they all look like that? Maybe too much fuel? You should only ever start the bike with no throttle. How many turns are your idle screws backed out from lightly seated?
Did you bench sync the carbs the last time you had them apart?

There is a fuel control problem in the carbs...no other way around it. I would get ahold of ( humbly post an add asking for assistance) from the local Chicago land gang. Someone needs to be hands on and go over every detail of them with you.
No need to get angry and frustrated..just get someone there thats experienced and get them out together right. If it ran for 15 seconds and died because the plugs were soaked with gas...then that all telling you it the carbs.
I can speculate and ask a zillion questions, but being hands on is the way to go here. I klnow you have done them so many times your pulling your hair out.
Get that done and the bike is as good as new.MY BIKES..1977 GS 750 B, 1978 GS 1000 C (X2)

Originally posted by myown550 View PostYes very good running, she fires up right away after you let her sit for awhile and there's no sputter at all just starts and idle starts to go up and just dies out. Then i try starting it with full choke-nothing, i let go of choke it starts for a sec again and dies out right away. I pull the choke again and backfired really loud. It got me really upset almost like she's doing it on purpose Yes i bench synced the carbs and i have it on 2 1/2 turns out. Im getting new plugs again tomorrow.

Check list that I can think of.
All jets poked and clean
No broke of mixture screw tips in the carb bodies
Rubber caps over the pilot jets and they fit snuggly
Proper float levels and floats are installed the right way..not upside down
New orings in the carb intake manifolds ( against the engine) and they arent pinched and out of the grooves.
All the float seats have good orings
No pin holes in the slide diaphrams and they are not pinched or out of the grooves in the tops of the carb bodies. Check this with a flashlight behind them in a dark room and look for pin holes or cracks around the outer lip areas. Note there is a dimple that lines up with the spot on the carb top.
To lean it out and not be "too lean" set the mixture screws at about 1 3/4 out from lightly seated.
Thats about all the basics I can think of other than having them in my own hands to see for myself..sorry I cant be of more help.MY BIKES..1977 GS 750 B, 1978 GS 1000 C (X2)

How well do the float needles slide in the seats? Sometimes gripping the seat with pliers can egg them out a bit and hang up the needles..either partly open or wont let them fall and open enough. May be worth seeing if theres any restrictions there too.MY BIKES..1977 GS 750 B, 1978 GS 1000 C (X2)

I am picking up what youre layin down...i get it. Thing is I am trying to figure out why there is that excessive fuel thats almost instantly fouling out the plugs...thats the core of the issue I am sure of it.MY BIKES..1977 GS 750 B, 1978 GS 1000 C (X2)
