Well...I did 2 things today at the same time, and wondering if anyone can tell me why my motor was so happy today coming in to work:
Until today, at lower speeds (<17mph) I would feel inconsistancy and slight hesitations in the motor. I was telling myself that it's switching back and forth from 4-stroking to 2-stroking because of my mixture. So the day before last, I moved the e-clip on the needle valve down (1 step) to the lowest position. That certainly improved things a bit, but didn't make the hesitation go away at lower speeds.
Today, for kicks, I:
1. Added a bit more oil to the mixture (I truly do not think this had an effect)
2. From the completely down position, I moved the choke lever up about 1/4"
I think the little bit of choke that I added in smoothed it all out at low to mid range on the motor, which is where I'm usually cruising at. Seemed a lot smoother.
So...question is: what exactly does choking do? It is limiting air or fuel flow? With the positive results I'm seeing, should I make a different adjustment to the motor, or just ride from now on with a little bitta choke?
Thanks,
Mark
PS. I will be picking up 2 new NGK plugs this afternoon...not sure how a better plug will add to the mix, but I need to understand the choke first so I can do this scientifically. (Yes, I know I shouldn't have made 2 changes at the same time, and I won't do that again...)
