Mike's Technical Corner:
Repairing your own Engine
If it has been awhile since you ran your engine - you may need some parts - a picture and idea about the condition and how it was stored will help me - help you get the "Wind In Your Face" sooner. Most engines that have spark and have not ran in awhile will need a new fuel pump kit, foot valve, primer pump, fuel hoses and carburetor cleaning. Spark can include an ignition module, spark plug and adjustment to magneto spacing.
PLEASE DO NOT ATTEMPT THESE WITHOUT THE LITERATURE - SOME PARTS ARE COSTLY TO REPLACE - ONCE LOST OR BROKEN YOU ARE IN A FIX.
We are a Tanaka parts distributor specializing in Bicycle Engines. These engines were made in the 70s and are Classics. If parts are broken or lost on during attempted they may be difficult to be replaced. Highly recommend you get the literature before wrenching on the engine.
We are happy to help you work on your engine. We have developed these parts by working with other owners and have sources to substitute other parts.
We do not sell parts to folks who do not have the literature. This is our hobby helping folks repair & maintain these engines. Have had too many times working with folks where something is lost or broken that should not have been because the person working on the engine did not have the benefit of this information. That can mean one unhappy owner. With this literature and a little elbow grease this little engine will last many years - that is our goal in putting this together - so folks can enjoy them for years to come.
Enjoy the engine - they are really neat little machines.

Literature & Parts
These little bike engines are really a HOOT. I have mounted these on mountain bikes, cruisers, three wheelers, and fold up bicycles - 16”, 20”, 24” & 26” bikes. They are such fun and real head turners. They are simple to work on but were designed by Japanese engineers so sometimes the why that way is interesting.
I remember seeing them in Popular Science as a 12-year boy - dreaming about having one. Fifteen years ago I found one at a garage sale and rebuilt it - took me about three months - no manual, parts lists or diagram - just trail and error.
I finally found a man in New Jersey who had one who had a manual and experience rebuilding these engines. We became and still are long distance friends. Once I got that engine running and rode it - I was that 12 year boy again - What a Blessing.
I have since rebuilt many engines and in the process of networking I have gathered an extensive amount of literature and experience plus figured out how to built or find parts that are better than original and cost less.
