Hoping someone may have experience this. 1988 Honda Goldwing starts fine but will idle erratic. When operating and when you ask it to go it bogs a bit and will catch up and run ok for a bit then it does it again. This trike belongs to my brother and I am trying to help him trouble shoot. Plugs have been changed, fuel filter, carbs cleaned, coils cleaned, traced vacumn hoses and found no issues. Read somewhere where a temperature control sensor could be the culprit. Also reading said that 1988 and 1989 used a different sensor than the 90-2000. We have had this trike to a Honda Mechanic but he did not mention this. I have asked for advice here before and really appreciate you all. It is hard to find someone in our area that will work on a 1500. I live it Ky so any help in a good reliable mechanic would be helpful if we cannot get her going.
