K1 - This is the bike I started restoring in March 2009. Rebuilt the carbs, air screws 1 turn out, points, timing, valves, sync, etc. New OEM filter and HM300's. The bike runs, idles and takes off without a miss. The problem I was having was it did not want to hold a cruise over 55 - 60 MPH and would try to die out. Not completely die out, just hesitate trying to hold a cruise. I could give it gas and it took right off at the higher speeds. But to hold a high cruise was the problem. An old Honda mechanic who owned the local Honda dealership lives in the area. He asked where my needle was set and it was at #3 position. He said that is only a "starting point" and told me to raise the needle 1 notch to a higher position allowing a little more gas flow. Did that today and appears to have solved the problem. Held a good cruise at 70 MPH. I do have some popping now on deceleration and at idle out of #1 pipe. Would this raised needle position need for me to adjust those air screws now? I was a bit concerned moving from the #3 position since the service manual says #3, but figured I could always put it back. What are your thoughts on this move? I certainly did not want to do something that would blue my HM300's.
Thanks
