The 750 came out in 69 so points was the standard for the day. The stock point system works very well as long as you keep up on the maintenance. If you dont have the timing, point gap and dwell set you will lose performance quickly. Point adjustments and timing are critical to how well the bike runs. Even with electronic ignition you will still have the mechanical advance so you will still need to check that it is working. Over time the springs lose a bit of tension and if not maintained the advancer mechanism it self can easily get stuck...either at base timing or at full advance. Little dab of grease at point change keeps them working and dont forget a dap of point rub block lube...most people never do it and 30 years later the lobes for the points get worn/ You need to start and go through all the basic tuneup items i you are having running issues...beings you didnt know it had points I assume you havent checked any of it. Point condition, gap, dwell, advancer function, compression test, valve clearances, timing chain adjust, running carb sync are at the top of the list.
