Hey ya'll, i need some help. i am trying to get a 1971 honda started. it has a kick starter on it. i have power going to the coils but i don't think i have spark. hard to kick it and look. the bike has been sitting for several years. i have been trying to start it with the batter charger on it. i did put new gas in it. the tank has been coated somewhere down the line. i have never worked with one of these bikes. any idea's. if i get it running i am thinking about getting it for the little woman. she wants to learn.

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!

not sure what model it is, it has semi off road tires/ road tread. it is 4 stroke. it seems like the gas is getting to the plugs. i tried to see if there was spark but unable to see it while i kick it over. i did spray a little either on the plugs and laid it on the head and no ignition. maybe it wasn't grounded good enough. the bike was running when the PO parked several years ago. i will try again tomorrow. i'm just not familiar with the kick start.

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!

Kill Switch?
Yep, I think it is called that way. Engine stop switch.The switch (usually on the right hand side of the handle bar) that you use when you want to stop the engine without turning the ignition off (with the key). Itusually cuts the circuit towards the coilsor in some cases shorts the circuit betweena coil andthegrounding (on the smaller 50ccmbikes without battery, chainsaws, etc.).

i flushed the gas through, tomorrow i will put new gas in again and some sea foam. i used a test spark plug at night and no spark that i could see. i sanded the points to make sure there was no corrosion there, i will play with the kill switch and try it again. i will keep you all posted

So first to get the spark back, then she will maybe fire?

Before the kill switch I would first check the contacts (where the wires are attached to the coils and points and capacitors), are the points and the capacitors grounded well, is there a power to the points (spliteach points, one at a time if there istwo of themand check forvoltage between thatpoint's input contact and ground, remember to split them first), check the ignition leads, etc. You mentioned you have power going to the coils, so probably not the kill switch as it usually cuts the circuit towards the coils. Try to put it in "off" position and see if the power to the coils will disappear. And remember the battery should be charged to geta goodspark!

Good luck!
