Firstly, yes I purchased the nearly finished Kubota D850 superdream from Tim.
Now onto the question.
When I got the bike, I Wasnt happy with how much turn of the throttle you had, so set to make it less/harder.
Here is a picture of the throttle arrangement:
What I did was drill the rivets on the arm, and move the adjuster further to the right. Whilst this did work, it gave me too hard of a throttle.
Whilst doing this, I Stripped the threads in the head for the bolt holding the ali plate on. These the adjuster lever plate in place. I had to remove all 4, drill out the whole and put a helicoil in.
I kept the springs connect and just moved the place out of the way, I didn't stretch them or put lots of force onto them. I was careful with this.
After realising that It was too hard, I put it back to how you see it above, but rather oddly, the lever action has moved towards to the bottom of the image. I have had to screw in the idle adjuster screw 5/6 turns, and also had to screw OUT the fuel adjustment screw 2-3 turns(!) to get it back to the same power output as before.
Not quite sure whats happened there.
Anyway, now its running as it was before, I would like to know how to tune the fuel screw. At the moment I have it set to that if i'm going 15mph, and twist the throttle to full, I get a small puff of smoke, then the CVT shifts up, then the smoke seems to dissapear.
Any assistance?
