I hope you will post some detailed photos of your final set-up.

throttle connection

So I think I am almost done with my throttle set up. I ended up using a few pieces from Ace hardware and pieces of the removed governor.

Pics:
1- piece from the governor that caught my eye as a potential throttle arm adapter

2-I dremeled the piece i needed off the rest of the governor control. I then drilled three holes in it (two to connect to the throttle arm and one connect the throttle cable to). The two holes that were for the throttle arm connection I threaded with my smallest piece from my tap and die kit. I also threaded the holes in the throttle arm too and bought two tiny bolts to fit the threads.

3- This is the mod in place. I used the little wire from the governor to connect the cable to. Spring has a longer lever arm to pull on which works well because the throttle cable contains so much friction, it will prevent a return if the cable and spring have equal lever arms.

My bike isnt functional yet but I will repost when I can comment on the real time functionality of my throttle setup. I really like the piece I took off the governor. It seems to work perfectly. I can get almost 100% of the intended throttle arm rotation.

Stupid question maybe, but why isn't it possible just to put on a stronger spring? (I don't have my kit yet so I haven't examined the problem first hand)

I was just trying to use the parts I already had. Sorry I was referring to the fact that with my spring it wouldnt return with equal lever arms.

I see, so the idea was to put the spring on a longer lever arm...

Also, i should say my kit didnt come with any throttle connections at all.

OK....I got my kit and now I understand the problem. I got nothing to work with. And, what's worse, the instructions say one sentence. "...and attach the other end to the carb." or something like that. Good grief. But now I will understand what I'm looking at when I study your pics Scottyo.

Throttle kits that might help?

I've been doing alot of thinking about how to accomplish this throttle connection lately and think that either of these kits would be very helpful

GXH50 Throttle Set Up

Its raining today in SOCAL so I thought I'd use the time to post some photos of my most recent solution to the GXH50 throttle cable hook up. I started out by purchasing a $8.00 lit from AGK (see photo #1). Then I added a few parts from the local hardware store and the local bike shop (see photo #2). I started out by modifing the governor vane by drilling out the bottom attachment point to 5/16th in. to accept the bronze bushing shown in photo #2. I then drilled out the ID of the bushing to be an easy slip fit over the governor rod the goes thru the case of the motor. This makes the governor no longer function. Then I added an L-bracket to the mid point of the vane for the spring hook to attach to. You need to get this attachment point away from the vane to get proper alignment. Last I drilled a new hole in the vane to attach the return spring. (see photos #3, #4, #5) The remainder of the photos show the various parts installed on the motor.

So I finally got my **** electrical problems figured out and got the bike started. AND Im very happy to say the throttle works like a charm!
