Motorcycle Repair: Wondering., honda 550, frequent service


Question
My husband just talked me into a 1978 Honda 550.  The bike looks good and supposly ran last year.  It kicks over but it does not stay running.  My husband assures me that it is just because it has been sitting.  He says tommorow he will get new plugs and that should do it.  He says Bikes are not like cars.  
The bike as I mentioned does start, but it does not stay running.
My question is, are Bikes much different than cars?  Is it likely it will run.  My husband is very good with working on things, but I am just afraid we got a lemon.

Answer
Hi "R"

Q: My question is, are Bikes much different than cars?

A: Motorcycles tend to need more frequent service to keep them running properly. The number one problem with motorcycles is gasoline varnishing in the carburetors while parked suring storage, such as during Winter. When this happens, the gas turn to a gel like substance and obstructs fuel passageways within the carbs preventing the engine from running properly. In severe cases, preventing them from starting. A good indication of varnishing is the engine will run on choke, but runs roughly or stalls when choke is off, even after engine is up to temperature.

Q: Is it likely it will run?

A: Sure. I suspect the carbs need a thorough cleaning, fresh gas, and maybe new plugs or at least existing spark plugs cleaned.

Send me an email address as requested. I'll return carb tuning, cleaning, and synchronizing files for your husband. He'll appreciate the information in these files. They are very detailed, professional, and easy to follow. Intel the service manuals leave out, so to speak.

Happy Easter and God be with you.
