Thanks for the input guys. Addressing some of the questions asked. I checked the valve clearances 3 months ago and changed the ones out of spec. Plugs are fairly new and gapped correctly according to manual. Carbs were checked out and adjusted 2 months ago by the same shop quoting me this work. They said at the time the points etc. looked good so did not change them. They did urge me to install Dyna electronic ignition at that time but funds prohibited that from happening. Spark appears good. Installed new coils last summer. Original coils on bike were cracked and gone bad. Guess next test is to get them to do a leak-down to narrow down the problem. again thanks guys!
