Ticking Noise

[kfsrq]

I am trying to rebuild my CB-77. I am an experienced CB-77 rider, from 1964 and more recent dates, and my current problem is a ticking noise. I have put the pieces back together, and I am looking at the upside-down engine, with everything in its place. The bottom cover is not installed ... but it has been, and the ticking noise persisted.

I have the Parts Manual, and on page 53 many transmission parts appear,
including the parts that are puzzling me right now. Part 19 is the Layshaft,
on which part 7 is a large gear with circular notches on its inside surface.
Part 20 is a small piece of metal (if it was a gun I would call it a sear) that
wedges part 7 so that it can turn in only one direction.

I know the Layshaft does not turn when the engine is running, but part 7
persists in turning, so part 20 clicks against every interior tooth of part 7.

If I simply continue with what I have, will the engine oil's viscosity prevent part 7 from
turning, or have I overlooked something? I am very puzzled by this, and am willing to
put significant expense into solving the problem. The bike has been off the road for
way too long.

PS. I am not quite a novice at this, I managed to replace a broken crankshaft in a CM-250.

With the tension of the kickstart spring on the shaft the ratchet will be held against the stop in the lower case and not be in contact. When putting the lower case back on you need to make sure the stop does not interfere or if you have removed the bolt stop you need to make sure there is no interference when putting it back in.

Thank you, Kevin. I am sure that advice is correct.
I remember, on occasion, nudging the kickstarter while the engine was running,
and of course the ticking noise commenced and continued until I let the starter
return to its stop.

I just am not sure how to achieve the goal. I must refer to the diagrams in the parts
manual, and to the instructions in the service manual (not very easy to follow!), and
make sure I get it together properly.

In 1965 I had two chances to reassemble an engine right. The first time, I must have
left a bolt loose on a shifting fork, because I did enormous damage in the transmission,
and resorted to buying a whole engine from a shop in Ottawa. The second time, I was
under more pressure because I was far from home. I did it right, and got home safely.

I will try to reach two-out-of-three this year.
I appreciate your help, and I expect to report success before long.

... or so it seems. But I think I have learned what I needed to know.

When I study the diagram on page 54 of the Parts Manual, I finally see what you meant.

Part 24 is the "kick starter stopper". As you explained, when I screw this into the lower case, it stops the kickstarter from rotating back past its rest position, and also depresses part 20 above so it does not interfere with part 7.

Success is within my grasp.

Many thanks. More reports soon.

I am grateful to Loud Mouse for confirmation that I am on the right track now.

He also gave me some valuable information concerning how to put the right cover back on.
The proper method of pre-loading the spring for the kick starter is very important,
and far from easy to impart in text.

Thank you again, Ed. I know I will never stop learning from you.

My Super Hawk is running well and reliably.
She starts with the kick starter with reasonable effort, and soon idles well.
She shifts through all the gears, especially engaging second gear well.

I am not used to a bike with a feminine personality,
but this bike is named Mary Ellen Carter. Anyone who knows the songs
of Stan Rogers will understand at once. Anyone who takes the opportunity
to get to know Stan's songs will find many wonderful rewards.

We are not all the way to a complete recovery. I merely wanted to report here
that this forum helped me in many ways to get my 1965 Super Hawk running,
after a long period of stasis.

Tasks ahead of me: rebuild the stock carbs, using kits I have ordered.
Reinstall the stock carbs, and park the XR-200 carbs which are doing the job now.
Fix the electric start. (I am 71 years old, and do not need to kick start my bikes a lot.)
Paint the tank and clam shells and taillight.
Find or make a duck-bill (or tail fin or mudguard, whatever that distinctive thing is).
Program a microcontroller to be turn signals and 4-way flashers and security.

... and most important ... RIDE!!!
