I got the 1986 Honda Elite CH80 from a close friend whom I lived with back in 1995. He had the bike in a storage area at an apartment complex we lived in together. I found the landlord of the complex, and got permission from my friend who now lives in AZ to take the bike. I took the bike in 2003 and took it apart. Washed it down with all the fairings off.
I took off the carburetor and took it apart, and used a sewing needle to clean the jets and float jet. I used good old Chem tool B-12, which most auto part stores do not carry any more. I also used canned air to blow all of the debris from the jets. I put the carburetor back on, but the bolts kept turning and would not tighten. So I tapped the intake housing, so I can thread the screw in and put a ten mm bolt on the back. Nice tight suction with no vacuum leak.
I sprayed Chem tool B-12 in the carburetor and got her started. Adjusted the speed idle screw and she ran wonderfully at 40 Mph.
When I took it to my sister's in LA, I think I ran hard down hill and lost compression. I checked the oil and saw fuel mixed in, which was not good. My first thought was I burned the piston and rings. I changed the oil and now I am in limbo deciding whether it is the piston and rings, or something else. I bought the service manual for her and will take baby steps.
