Starter Removal

Post by Newbie »

I've got a bit of dreaded starter run-on w/ my '80 CBX. I do all my own maintenance, so am familiar w/ the bike. The shop manual isn't really clear on pulling the starter. After removing the CS cover, ground & power connections and the 2 end nuts, what's next? The manual doesn't mention having to tilt the motor.

Any advice would be greatly appreciated. TIA :?

OBTW, I replaced the starter solenoid also.

Ooops. Just kidding about the 2 end nuts. :oops: Took off the CS sprocket packing (you know, that curved thingy around the sprocket cavity), but can't seem to figure out how to persuade the starter to jump out. It feels pretty solid in place. Come on guys, what am I missing ?

Starter Run-On ....

Post by John S. (5594) »

Could be a fairly complicated task.



I have starter run-on on my red '79 and have done most everything with the starter and associated electrics - but the trouble seems to be the starter clutch within the engine cases.. Tried changing the oil a few times (probably just a shot-in-the dark - but easier than splitting the cases). Did also drop the oil "pan" to check for metal - nothing there.



A fairly low mileage example (~15k) - and well maintained - I am afraid that I will have to remove the engine this winter and replace/repair the internal starter clutch.



I posted on this subject some time back - had read long ago about this problem - but no-one that responded had any experience. Oh well - I suppose I will have soon enough.



If anyone here can shed further light on this problem - you may save two CBX owners a pile of trouble :)



Good luck and all the best,

If I recall correctly, there are two bolts that hold the starter to the case. Pull those and it should come right out. Might have to pry carefully to get it moving as the o-ring might be hard from time and heat. Hope this helps you.

Hi Skip,



Just curious here. Since the starter clutch is internal to the engine - how is removing the starter motor itself going to resolve the "run-on" problem?



Could use any and all advice myself.



All the best,

Thanks for the information and ideas. BTW, 2 questions.

#1 Are the two bolts mentioned accessed from the alternator side or the clutch side. I haven't been able to find them, but haven't gotten to tilting the motor yet.

#2 Will it damage the starter or gear to leave it as is? I'd rather not pull the motor apart. I'll try the multiple/early oil changes for now. It's a very sweet/original black Marysville w/ a sport kit and original mirrors w/ 17K on it. I love riding it so much on weekends, don't think I could bear the time it would incapacitate the bike.

Thanx again for all the advice.

To remove the starter, pull the countershaft sprocket cover. Then remove the spacer under the cover. There you will see the starter with the two mounting bolts. Remove these two bolts and the starter will come out. As far as run on, I personally have not had any problem with this, although I have heard others have. If it is in the starter clutch, the only way to gain access is splitting the case. I think I would look at a possible electrical problem first before commiting to removing engine. BTW, no need to tilt engine to remove starter. Hope this cleared things up a bit.

Pulling the Starter

Post by Tom Neimeyer »

I'm not sure, but I think there is another step to pulling the starter. On my '79 and '80 there is a "chain guard" that is part of the engine spacer top mount that also keeps the starter from coming out. When I have tried to pull the starter, I had to remove this piece. that being said, I have also seen where some poeple have modified this piece and do not have to remove it to pull the starter.



Anyway, to remove this piece, you have to partially remove the upper rear engine bolt.

Tom, you are correct. That is a chain "guide" that would either have to rotate out of the way, or remove. Loosen the thru bolt nut and it should rotate. If its still in the way, lift slightly under the rear of the engine with a floor jack and remove the thru bolt enough to remove guide.

I'm stuck removing and checking the starter. I've already replaced the solenoid. No change. The darn thing fires right up, but the starter still just winds down for 1 to 1.5 seconds after it catches. :x

Try punching it out from right side w/ a piece of wood and a hammer, they need a bit of persuasion. All fasteners and brackets removed first, of course.
