I have an 86 with only 17,000 miles on it. I am in the process of putting a stator in the motor. Being that I have the engine out, I am going to get rid of all the air filter stuff. I have found some Emgo pod filters for the carbs. Also. I have punched out the cross over in the muffler making it kind of flow though. With both of these changes what would be about the correct size for the main jets? I am thinking about 142 or 145 from 132's stock. The pilot it now has in 40.
