How do you adjust the chain on a 1986 Honda fourtrax 125?
Adjust the sprocket of the chain
Sorry for my English I will do my best to explain this. The carbs of this Honda Magna have a knob in the middle of the carbs. It is for idle adjust, but is the problem is bigger you have to clean the carbs, check the jets and diaphragms is better if you can use an air compressor or maybe a vacuum sincronizer.
