While putting everything back together tonite I noticed in the bottom of the signal generator casing a broken small spring sitting there , now I know theres two springs in there and its not such a big deal !! Im sure I have a spring kicking around .but not my brain is turning and I want to understand how the governor assembly works and whats its purpose ?? Yeah im sure this isa stupid question , but hey its after midnite and I have been working on a bike for 7 hrs , so I think im entitled to a stupid question.... hahaha
 
Mechanical timing advance. There are weights, they spin, the springs hold them in place until enough centrifugal force is generated.
 
The springs hold the timing to about 10 btdc at idle and then gradually release as revs go up. You'll need both- did you find the rest of broken spring?
 
Those springs will have equal pull strength, you can't just install another spring, it may not have the same tension. replace in pairs
 
Ill pick up two then ... now tell me what would the symptoms be if there was only one of these springs functioning in there for say the last two weeks ? What would happen ? Would I notice a difference ?
Was up till midnight got the old valve gasket finaly all cleaned off , and the new gasket installed , carbs are back in after poking and spraying every hole and replacing all o rings on mixture screws .. tonite I guess I jump in and learn about points !!

If you were running the bike with 1 spring , you would probably experience poor throttle response off the idle circuit, in other words the ignition timing would be OK at idle but would probably advance to quickly as you turn the throttle, causing either a hesitation or a stumble.
 
No Tom I have not found the broken piece yet ...
Appears as though just half the hook part of the spring broke ! Ill take a looke around for Iit tonite ..

Thank you !! That is exactly the symptom I was experiencing !! And I thought it was the fact that my o rings on mymixture screws on #1 & #2 carbs was causing the issue ..
Ill pick up 2 new springs and already installed 4 new o rings and hopefully the bike will be back running good ..
 
Looking forward to getting this gs650gl out of my livingroom , and moving my new 78gs1000E in !!!
 
Broken spring !! These older bikes sure do get frustrating ... replaced fork seals ,all rubber intake boots , new filter , new tires .carb cleaning , R/R, battery , valve cover gasket , shims, new battery , spark plugs and caps ... Now a tiny little itsy bitsy spring ...sure would be nice if something didnt break for just a week or two !!!
 
All in the last 2 months !!! Said a prayer to the bike lords above last nite .... NO MORE PROBLEMS JUST FOR A LITTLE WHILE !!!
 
Does anyone know of a good link or site on information about the signal generator and governor assy ?
Would appriciate it .. been searching and cant find anything
 
Bugger I cant find 2 new springs anywere ..
And the guy at to cycle says he cant just sell me 2 springs he can sell me the hole governor assembly ... grrrrr

be careful what you wish for! This could be like changing girlfriends- looks good at first, but then......

The guy that's been selling all these parts to you should just give you the governor assembly,cuz you're his meal ticket or his alimony payment! Besides, he'll likely make a killing off the gs1000 too !
 
I agree with you 100?/○ Tom !!! Free sounds awsome ... lol like help a single full time father out thats raising two daughter !! Haha
 
single guy ,two daughters !

Finding springs is very challenging!
I checked my old spare governor; the wire thickness is 1mm, the outer diameter of wound part is likely 5.5 mm. The eye center to eye center is 15mm; material is music wire not stainless. A little variation is probably OK, by 4k the spring is fully extended and hits stop.

Thanks for the info on the springs Tom ..
And yeah single full time dad ! What women is going to tolerate me with 2 motorcycles parked in the livingroom ?? Hahaha
 
For the time being this will have to work !! Spring with hook broken off , repaired by bending up one loop and made a new hook and just to keep things the same I removed the spring that was still good and did the same ... hopefully I can come to a better salution over the weekend !!!

That will not work as it will put more tension on the spring and not allow the advancer to move when it is suppose to. Possibly not allowing the bike to accelerate my guess above like 4500rpm and up. It will act like a stuck or frozen advancer.
