bike won't start.

And which model is it (as it is not a Goldwing, they showed up in '75th)? Is it a two or four stroke engine? Anyhow, first thing I would do is to check the engine oil (if 4 stroke) andreplace it.Then remove the plugs and put some engine oil directly into the cylinders and crank it slowly for a few times to lubricate and preventdamage tothe cylinders and rings.Then switch the ignition on (still with the plugs removed) and put a plug in its cap and rest the central electrode against the grounding and crank the engine slowly with your hand to see if there is any spark on the plugs. If no or week spark then try to determine the cause, you said therewas the power on the coils so check thecontact breakers and capacitors,ignition leads, the plugs themselves, the contacts....also check the coils as that could be broken as well. However, if there is a normal spark on the plugs then check theignitiontiming and adjust if needed. Make sure that the carb(s) are getting the fuel from tank, and after that (if still won't start) remove the plugs again after the cranking and see if they are wet/if they smell of fuel, if not then probably not enough fuel feeding (carb problem).

Also pay attention to thecamshaft timing belts(if present) and to thevalveclearances.It would help if you could find some service manual or something....



Good luck!

Change the plugs if youhand't alredy. The plugs willalmost certainlygo south after a several years of sitting. Thenif I were you I would firstmake sure if there is the spark or not (find some assistance if needed). Do not spray the plugs with anything as that could short the electrodes. If you are sure that there is no spark and the gas is getting to the plugs thensome electric problem is the matter. If the engine was running before laid up then we can assume that the coils,ignition timing and capacitors are good, as sitting shouldn't affect that. Thesitting also shouldn'tdisturb the valve clearances, though thevalves could get stuck alittle, but that will hopefully go away once the engine is started, though you could check the valve clearences as well.However the points (contact breakers) probably need cleaning, as do the othercontacts (on the points, capacitors, coils, etc.).Also check the ignition leads and the plug caps. Check theengine "kill switch" if present, if it's shorted or something it will kill the spark.Then I would check for a spark again. If it's still gone than try to find out why. If it's there and the engine still won't start then the carbs might bewrong as well (though they certainly need at least a goodcleaning, but I hopethey are able justto start the engine).Once you are sure that the spark is present and the engine still won't startI would first checkfor the cloged jets and stuck floats.And shouldn't forget the air filter - are the carbs getting enough air? However, if thefuel is comming in the cylinders then I hope that it will start oncethe spark is there.And change the engineoil if you didn't!

Well, I hope that the old girl will fire up soon!



P.S. I forgot to mention, the battery should be charged to obtain a good spark. So charge the battery first of all!
