1970 Honda CB 100 Problems

I’ve replace evrything on bike, points, stator, harness, coil ignition still no spark. ny ideas?

to find the timing marks

I am that you are talking about the on the points plate.

Before you put the and point plate on, check the advancer for proper function. the point cam and it should snap to the correct original location.

If not the relationship between the point cam and the base. HINT. you can put it together and the bike will NEVER

The points should mount up on the with no problems, other check carefully where the wire goes onto the bolt and don’t let the terminal end get out on the point base/plate. Point and points should install so the are at about 10-11 o’clock when the plate is secured to the head. The point wire the point base plate at the far and runs underneath the point cam to with the contact breaker on the side.

When installing new be sure to check and clean the faces of any grease or oil that is a Put a drop of oil on the felt and a light of point grease (if you can find it at auto parts stores) on the cam. Because the point block is new, the little spots will wear initially in the first couple of of operation, so you will probably to come back and recheck the gap and after some run-in

The gap needs to be about .014-.016 at the highest point of the point Turn the engine over a wrench and watch the points and close, then observe they are open the widest and the gap with a flat feeler If you set them about .016, they will close to around .014 or so after have seated in.

This is how it is done in a perfect of new, unworn parts.

The difficulty here lies Honda’s choice to cutaway the cam to facilitate camshaft installation. area tends to wear causing the camshaft (and cam) to wobble around rotation, even when the tensioner is fairly snug. If you the end of the point cam or camshaft with fingers, try to move it from to side/up and down. ANY movement translate to a change in the point which makes a change in the timing.

If it is really loose, the will be difficult to set and the running will be erratic. The only way to fix it is to put on a new and cam and/or POWROLL may still be to convert the head/cam to a needle design. all a lot of work and expense for a 30 old tiddler bike.

The timing, once the gap is set properly, is by moving the point plate and forth until the points BARELY open when the F mark is aligned with the mark on the case. You can check with a 6v test light or a or audible test unit. the point gap when you move the as it tends to change the gap.

Go back and forth until you both the proper gap and the correct opening moment set.

bike MUST have a 6-volt battery installed to It is NOT a magneto ignition.

Hope helps out. Let us know how it

stuck in gear

The bike has a shift fork. This the engine comes out and must be torn down to fix the bad fork. The top end apart, the flywheel, electrics, shaft, clutch, main gear, kick starter. drum index wheel all come apart then the gets split open for to the shift drum and forks. is not a job for the home mechanic.

You have a few more problems I had mention.
