Thanks for your reply. Will check these out also to rule out any potential issues. 🙏

Ok thanks. I will have a good look over the wires on mine whilst I am doing.

Thanks for the reply Wow. Did you ever get to the bottom of what was causing it? Dodgy CDI's ??

Evening all, was hoping someone might be able to shed a little light on a problem with my sons 125. Its a 2019 125 and after about 30 mins of running it runs rough and won't go. I have had the carb off stripped and cleaned it all a couple of times now with no improvement. I have replaced the seal on the bottom of the choke plunger also. It runs for about half an hour absolutely perfect then starts to struggle and run rough. Won't rev etc. If I take the plug out its all black and sutted up. I cleaned it off again today and it still wouldn't go. Last time it was out, it did the same thing and we put a fresh plug in it and it went again. Its only a quick fix solution though as next time it does the same again. I was thinking possibly CDI?? Has anyone else had the same thing or able to point me in a direction as to what else to have a look at. Thankyou kindly in advance.

Quick hello, I have been trials riding off and on for years since I was a kid. Got my son involved now so try to get out at least every month. Hoping to have some help on a few bike related issues. All the best
