How do you stop a Honda cr85 from bogging out at low revs?

If its bogging out at low revs it is most likely a clogged up idle jet, you need to take apart the carburetor and clean out the idle jet but while your at it you might aswell clean the whole carb. search on YouTube 'how to clean a motorycle carb' and it should give you step by step instructions. As a temporary fix spraying CarbCleaner into the petrol intake of the carb may fix it but your better off giving the whole carb a good clean.
