Question about 1970 Honda CB 100

1 Answer

Kick start lever is loose and teeth are not catching on the shaft. How do I replace? I found a part on ebay brand new in thailand but not sure if it will work since the previous owner changed the kick start shaft to a larger diameter shaft.

You may want to get a service manual to work on this one. The expanded parts diagrams that are available for ordering parts online will show you all the parts. If you can not find some picture of the 100cc models the 1974 CB125 is basically the same. The design of your motor dictates that you will have to take the engine out of the frame, pull the top end off, and split the cases to get in to the area that houses the mechanism you want to replace. You may be able to pull good used parts out of a salvage motor locally or even purchase a used motor or donor bike if the price is right. You will need a complete gasket set for the motor. As for the change in the kick shaft size, it may be that the shaft was replaced before with a shaft from the CB125. You may have to measure your shaft and then measure the shaft on the motor you are taking the replacement part out of. Chances are you need to replace several parts to repair the kick mechanism. You will have to disassemble the motor to find out everything you need to properly fix your classic.

I have a 2000 Volvo s80 and I can not get it to turn over or even fire

Hi,regarding your Volvo s80, have you noticed recently in the past that it almost did not want to start and maybe sometimes it did start?
I am asking to see if you noticed this recently?
If you do not hear your car even click, when you turn the key,
Have you checked your battery,and the battery wires to make sure the battery is good?
Maybe the battery needs to be replaced or a wire is loose and there is no connection with the battery,and wires, please check your battery first.When was your battery last replaced? Check the battery cables to see if there is any
noticeable corrosion that you can see that might be interfering with the contact.(If you see green and or white powder try cleaning off this area with a battery terminal brush)
Remove the terminal wire clamps, most can be loosed and removed from the batteries positive and negative terminals with a flat head screwdriver.
Then clean the area with the battery terminal brush ,if it has the green/white corrosion,you will be able to see if it does.
Be safe and protect your eyes always with safety glasses.

I just went through this with my daughter's car.
The Volvo s80 also has what is called a flywheel. (Very expensive to buy new from the dealer, it will cost a few hundred dollars)
Tip, If it is the flywheel you can shop around for prices depending on your budget and preferences./(New or used)
Yes,you can replace the flywheel even with another used flywheel,just make sure the teeth are not damaged,or worn.
A used flywheel could save you money, which most likely will be needed to pay someone to replace and do the work,if it is the flywheel.

Replacing the flywheel entails taking apart the entire front end,
the entire suspension needs to come out if it is a front wheel drive,
the engine needs to be dropped,
and the transmission needs to be separated.

Second and very important tip make sure if you are replacing the flywheel that the new or used one is an exact match for the one that is in your car.
(It must have the same exact number of teeth.
(I learned this the hard way)
Some flywheels have 133 teeth and some maybe 142, so make sure it is an exact match.
You do not want to have your car taken apart,and put back together again and find out it is not starting after all this work because you bought the wrong flywheel.
If the flywheel in your car has 133 teeth then a flywheel that has 142 teeth will Not match and you don't want that to happen,because your car won't start after all that work and you have to do it all over again which will cost money.
The flywheel is a large almost 12 inches in height and 10 or so inches in width,heavy metal circular shaped piece that has grooves(or teeth that go all around the metal,if any of these teeth are worn down what happens is when you try to start the car it will turnover but the car won't start.
The reason is the flywheel rotates to catch on the grooves and sometimes over years there could be an area were maybe even 2-3 of the grooves(teeth on the flywheel becomes worn.)
If the flywheel has damaged or worn teeth ,it won't be able to turn and catch,and the car won't start.
If you do not have someone to do this type of work,take it to a transmission shop and they replace flywheels

I hope maybe all you need is a new battery.
Keep in mind the flywheel ?

My daughter's car is a Volvo s80 2003.
I'm not sure how many miles are on your vehicle or if you just bought the vehicle,but over time If the teeth are damaged or a few,even 3 teeth in a row are worn down,this can happen and the car won't catch to start.

As I mentioned the cars flywheel turns and the teeth have to catch on the starter and the flywheel rests on the starter enabling the car to start once the teeth catch.

We also replaced the starter which went through a toll from her continuing to try to start the car.
If it is the flywheel it is always good to replace the starter also in th s80.

I hope this information is helpful to you.
If your wondering,we went with a used flywheel and new starter and now the car starts great.

Why does my starter not disengage after the bike starts

Solenoid is sticking, age,heat, dirt etc on the solenoid shaft makes it stick. It may be possible to replace the solenoid assy, but easier to replace the unit as a whole motor and solenoid, it may also be non serviceable. Make sure you did not loose any teeth on the flywheel. it will make a deadspot, motor spins free without engaging the teeth. And if it catches one while spinning it will break another one off. Good Luck

Shift lever

Possibly the lever's locking bolt thread has stripped or the thread on the bolt is worn. Another aspect is the splines in the lever are shot and/or the splines on the gear change shaft are badly worn. Remove lever and check the splines on both shaft and lever also check around the lever fixing section for any cracks. Check the threaded section of the lever with a brand new bolt the bolt should be easy to turn in and out by finger and should have no side to side play. When refitting the existing lever or a new one make sure the lever is a good fit on the gearbox shaft splines before you tighten the bolt.

Kick starts slipping it not engaging,can you help me please,with advice and cost.thanks

Is the lever sli[[omg on the shaft ? OR the shaft in the case is not holding?
The lever can feel tight yet be loose when kicking. Remove the lever and check the knurling on the shaft. If the clamp bolt is not kept tight, the lever will slip and destroy the shaft knurling as well as the lever and they won't grip each other. If you replace the lever, you will need a new shaft also.
Good Luck, -Ned-

1974 honda scrambler wont kick start their is nothing their whats wong with it and my start button is no good so i got a bike that wont go anywhere

You have probably sheered off the teeth that engage the kick start with the gearbox, else ( more commonly ) the spline in the kickstart lever has worn out and is slipping on the input shaft.
You should still be able to bump start your bike ( in second) .
All the relevant broken bits are on the right side of the engine, I would remove the kick start lever and remove the right crankcase cover for a look.
You should still be able to get bits for your bike, they are getting collectable and some parts interchange across models.

Have 350 dirt bike kick start was ok left bike shed for a while used kickstart ok but next time it appears jammed wont move tried rocking in gear to free up but no go. Do you have an idea as to what might...

Assuming the engine will turn over, the ratcheting assembly on the kick starter may be worn. Remove the kick start lever and then the side cover, (place a pan under the bike to catch any oil). The kick starter is basically just a gear and a spring; the gear will in some manner engage the flywheel, (sometimes indirectly). Make sure there is nothing obvious wrong such as broken teeth or debris lodged in the mechanism.

The other possibility if the engine does not move when rolled is the timing chain may have jumped teeth on the cam sprocket. To get to this remove the gas tank, remove all but the rear engine mounting bolts, remove the valve cover. To check remove the fly wheel cover set the piston to Top Dead center, (TDC) on the compression stroke and make sure the mark on the cam sprocket is at the top of the sprocket and not off set.

Good luck.

Kick start thinggy on the engine as rounded off

Usually a Honda part will fit those pit bikes. Honda 50-150 cc should fit. Take a file and clean up what you can of the splines on the shaft going into the engine. Fully remove the bolt and nut before removing the kickstarter as the bolt is in a groove to help retain the lever. Refit the new lever and tighten down well......Good luck to you...Tim

Kick starter

new spring and little ball. My question is were does the little ball and spring go? I tried to get it down where the bolt threads in but no dice. Any help would be great.That's the detent for a fully closed (folded) kick start lever. Look in the splined base which you ordered (female) which fits on the kick lever shaft (which is also splinedbut male) there is the hole where the actual kick start lever fits. This in the same plane as the little indent in the lever it self. Put in the spring, Then the ball on top, press the ball down with a small screwdriver or whatever from one end as sliding the lever in from the other. Once the lever end has started over the ball just push in all the way and turn to engage the lever a couple of times to make sure the detent works. Then slide the unit on as you would any kick start lever. I did this in the field yesterday, so its not difficult. I used an allen wrench to push the ball down. Took maybe a minute. Hope I did not over explain, its pretty obvious if you look at it enough. Good luck.,,,
