There is a one way clutch that grabs onto a smooth cylinder on the side of a large gear inside the motor. The smooth barrel surface is damaged or chattered so the one-way clutch will not grab on the side of what Honda calls the "starting sprocket". A chain connects the starting sprocket to a smaller sprocket that has the starters spline plugged into it. The chattered surface does not allow the three small barrels of the starter clutch to grab and turn the motor over. The sprocket runs about $70 and the gasket runs about $30. This is an internal motor part so you will have to take apart the motor to get to it. If you go to you can look at the microfiche for the motor and see the parts you are looking for.

soory about your trouble but it sounds like the yoke inside the starter itself is not engaging. If you know how or know someone that could take the starter apart and try to grease the yoke shaft so it can slide freely back and forth it should do the trick.

no need to gap them if they are new. straight out of the package is just fine. you only ever need to gap used plugs after you clean them, cause as they wear the gap gets bigger.

I just purchased a 1984 700 nighthawk and the starter doesn't work. it has a good battery, but the gear indicator always says it is in fourth gear. could this be the problem? if so is there a way to...

i think the starter operation is basicly like a manual trans automobile, in that, it has a switch in the clutch system that does not allow the starter to energize if the clutch pedal is not depresed which closes the switch.

i suppose you tried the starter in neutral. so perhaps you are correct in assuming since the 4th gear indicator light remains on; it's acting like a neutral safety switch in a automatic trans in a car, the starting system thinks your in a gear, and disables the stater motor circuit.

if you diconnect the light, you probably won't take care of the problem. you could get yourself a repair manual and see if you can locate the problem. i couldn't give you any advice on fixing, i'd have to be there. i'll try to look around for you though
