I’ve recently bought a Honda XlR125RW and it has issue idling (cutting out), after adjusting the ideal screw it idles a lot better. However will still cut out randomly so I was testing the spark with a new spark plug and it has spark but it will randomly stop sparking one of the jets in the carb is not original and is smaller or bigger I’m unsure of which as didn’t do it myself I know very little about bikes could this be the issue or is it something else? any help will be much appreciated thank you.
