air filter hoses
air filter hosesHi, I have a 66 honda dream, The airfilter has 2 hoses attached and running to a port on each side of the motor. Could someone tell me the purpose of these hoses. What do they do? Thank you, Fran
air filterConsensus here is that they do pretty much nothing.
They were discontinued on later Dreams. Intake valve guide ventsFracro they are intake valve guide vents. The therory was that by venting them it would help keep the motor from sucking oil past the valve guides during deceleration as the motor has no valve guide seals. It did'nt work very well and honda deleted them from the motors in later years.

Thank you for responding. Thought maybe that was our problem. We realized we hadnt hooked them back up and now w have a timing problem. Here is the problem:
WE rebuilt the carb, (original), installed new points, plugs, wires. We set the timing by lining up the red F and the arrow on the case. Bike will start right up( but, when I ride it and give it full throttle it acts like its running on 1 cylinder and it will shut off when you let it go back to an idle. Now the exhaust pipe on the right side of the bike is turning blue. Question?. I know this sounds silly, but, When you are sitting on the bike, which cylinder is the # 1 cylinder. We used the the cylinder on the left to set the timing. Could use your help or suggestions.. would really like to get this bike running. Fracro
We used an Inductive timing light to set the timing. 1st, We installed new points and set them to 14 thousands, (0.014 ). We then hooked up the timing light by hooking Hot and negative side of timing light wires to the correct sides of the battery. We then hooked the end of the timing light that goes around the spark plug wire. Next, we started the engine, ran till warm, then pointed the light at the flywheel to line up the red F on the fly wheel with the pointed arrow on the case. We lined up the marks by loosining the screws on the back plate of the points and moving the plate to line up our marks with the flywheel. We were careful not to move the timing mark while we were tightening up the screws on back plate. Now, the bike will start up OK but, after a short warm up, if you give it full throttle, engine sounds like only 1 cylinder is firing and bike has no power. We have noticed that the exhaust pipe on right side of bike(sitting on bike, right side) is turning blue and the other side is fine.. Any suggestions will help. thank you, fracro
Wrong! Static timing first -- use the timing light to check that full advance doesn't exceed 45º-48º. Sounds like another issue other than timing. Maybe valve clearances or valve timing a tooth out? Or perhaps just a duff condenser -- that symptom is indicative of it breaking down under load. There's no #1 cyclinder; just L & R. The header pipe? Could be something as simple as an AfterMarket, single-wall pipe fitted to that side -- they go blue in a heartbeat; or could be a weak (lean) mixture. Theoretical scenario: Mixture is weak / ignition is over-advancing Left side isn't firing under wider throttle openings Ergo, right side is combusting and will display overheat tendencies (blueing header)?
