Without the year of the bike I am hampered. Lets assume it is an older bike and has a set of ignition points and not a CDI model.
.
Pull the cover off the shifter side of the engine. Remove the spark plug then turn the flywheel so you can see the points. Oil on them? Dirt, or rust? Next check the main bearing. Do not rotate the flywheel but instead hold the flywheel firmly and lift it up and down, left and right. Was there any movement or was the flywheel rock solid?
.
I am willing to bet that the points were dirty and there was a lot of play in the crank bearings. If so, you will need new crank bearings and seals plus new points and condenser. The engine needs to tear down into about 75 parts in order to replace the bearings. The job requires some special tools to remove the flywheel and clutch, plus a crankcase separator the split the gearbox.
.
This is not a job for the beginner. I suggest you have the shop do the work and also that you spring for 3 more bearings and seals plus a fresh cylinder bore, new piston and rings and a new spark plug. You now have a brand new engine that should run well and last for many years. Please rate this solution. Thanks

SOURCE: 1971 yamaha 175 motorcycle electrical problem

ill do a list of things that can help or be the problem.

1) Pull the coil off and wire brush down all the bare metal. then do the same to the frame where it bolted on. Make sure there is a grounded wire that bolts back onto the coil if there was one, Replace the wire end for the ground peice.

2) Pull off the spark end cap and cut the wire down a few mm until you see new wire then screw it back on. (if its NGK)

3) follow the wire from the kill switch and make sure it isnt grounding out.

4) Hotwire - find the kill switch and unplug it. if this doesnt help unplug the ignition key wiring. on older bikes it will work for ignition but not lights for the key part. if this helps you need a new Ignition barrel / Kill switch.

5) check your wiring harness make sure it isnt grounding anywhere exept where its ment to.

6) make your your engine to CDI is plugged in and has no oxide in it

7) try and find somone with a running bike the same as yours and borrow there CDI, if this helps you need to buy a new CDI or check yours for wiring shorts.

hope this helps if not buzz me ([email protected])

Is it off on both upper and lower sideband? how about AM? Did someone mod it so that the clarifier works on transmit too? Hope not.
If it is off on LSB adjust CT2 next to C104 and for upper side band CT1 next to C105. You will be tweeking on a capacitor in series with a crystal. caution as it could stop it from transmitting (oscillating) if it isn't set right. best if you use a frequency counter to see if the stage is working right on frequency. Here is a diagram hope you know how to read one. If you dont and you attempt to tweek on this and that, you have a great chance that you could foul it up to the point it wont work at all or sound really bad. The main thing is to narrow it down where the problem is: Is it just LSB or USB or both? If both do not tweek on C1 or C2. I would say it is the 11Mhz crystal area. meaning the problem could be a bad varactor diode, even a resistor or capacitor failure in that portion couldmake it off frequency as the varactor is voltage controlled. By varying the voltage to it, the capacitance changes and therefore changing frequency.
If both uper and lower sideband are off then I suppose AM is off too. the reason you are not being heard as well. Adjust CT3 to bring it back on frequency. You got it CT3 if upper and lower and AM is off or if only lower is off CT1, if only upper is off CT2.
Good luck. I am not responsible for your actions. I am only giving my opinion and logic on this. here is the diagram, dont hurt yourself.....

I want to wire up a ct1 175 enduro yamaha to only have a headlight , and the ignition was missing when I got it ...... Where do I put the kill switch ? Before the coil ? And , can you tell me where ea

1. The can looking thing should be a oldtime flasher and can be gotten rid of.
2. The ignition kill switch should be grounding the point set (it should have points on that model). Find the wire that comes from the point set on the engine (should be under the flywheel but the flywheel does not need to be taken off to see it or find it).
3. headlight - if all the wires are still in place on the bike, connect the battery up and turn the key to the second position (which is the headlight) , probe the wires(with a voltmeter)coming off the ignition switch until a wire is found with battery voltage (should be 6 volts). The wire should only have the 6 volts when the switch is in the second postion; connect that wire to either the high or low beam side of the headlight and it will give you a light.
4. Also if you should video again and add things like wire colors, showing the handle bar switches, ignition switch and all related parts, it will be easier to give more information about what you are trying to do.
