So a few months ago I purchased a 83 GS650G as a non-running project. I have rebuilt the carbs, new battery, new plugs and the bike wants to start but will not. I'm getting fuel to the carbs, each cylinder has spark and motor has good compression. I was thinking maybe the timing was off but seems from I've read in manual that its a non adjustable system. Any ideas or pointers are greatly appreciated. Just getting bummed about the money I've invested and she won't come to life.

How far in is the idle knob??? Turn it out till it isnt touching the throttle linkage. Then turn it in till it just makes contact...and then go in about another 1 1 /2 turns. TOO much opening and they start hard. Then if it starts get it warmed up and adjust the idle to about 1200.
Second thing is where are the mixture screws set at??? Average starting point is 2 1/2 to 3 out from gently seated. And when you rebuilt the carbs, did you poke all the holes in the jets out with a fine wire? And did you get the hole in the very tip of the pilot jets clear???
Tight valves will also contribute to hard starts..adjust them if you havent done so.MY BIKES..1977 GS 750 B, 1978 GS 1000 C (X2)

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. -
Dont be twisting the throttle grip either. Hands off. Full choke and hit the starter button.MY BIKES..1977 GS 750 B, 1978 GS 1000 C (X2)

I will have to check the idle knob, When we rebuilt them we also did stage 3 from dynojet so all of the jets and such are new, mixture screw is 2 1/2 turns outComment

Yes, check plug wires. Left ignition coil fires 1 and 4, etc.
Briefly use prime position on petcock. Apply full "choke" and make sure that cable activates at carb end- rod slides to left about 1/2 inch.1981 gs650L

do you have the stock airbox or pod filters installed? if stock, why the stage 3 kit? and when you rebuilt the carbs, how did you do so? have you verified spark to all 4 spark plugs? have you checked your valve clearances?Comment
