Hi I have a 31k had it all running many times this year since a engine and carb rebuild and have ridden it 120 miles or so this year so far to test it etc, but have now developed an intermittent starting problem where some times it won’t start and has no spark. ive checked all wiring and replaced the spark plugs and leads, fitted new battery, but now sometimes it’s all ok got a spark and starts up first kick, but then for no reason no spark again. Yesterday wouldn’t start and had no spark again so left it, then came to it this morning fired up first kick! I’ve also noticed the power valve servo when turning the ignition on does the clean cycle ok but then with ignition still on and engine not running sometimes stutters and makes a noise and twitches, not sure if t could help point to the fault, could it be the CDI causing both issues intermittent spark and the servo twitch? Or any other ideas what to check? Coil?

If it's a 29k50 cdi you can probably guess what I'm going to say 💩
