Yea I have yet to see any Honda built in the 80's that didn't have electronic ignition. You may be able to rotate the pickup plate though for minor timing adjustments. Valve lash is a must check and should be done every other oil change. Have you made sure your air filter isn't clogged or that you have rodent nest in the airbox. Once all that has been done if the problem persists then it is a good carb cleaning time. As for the sprocket issue, when you say a smaller one is installed, are you talking about front or rear. How sprockets work is smaller up front, or larger in the rear will raise the gear ratio making the bike accelerate faster but sacrifice top end. conversely adding teeth to the front sprocket or reducing them from the rear will decrease acceleration but make the bike cruise at a lower RPM on the highway. For every 1 tooth up front is roughly equal to 3 teeth on the rear.
