Honda Cg125 2002 electric start ac generator wanted?

Q) I have a 2002 electric start Honda CG125 CDI. The generator(ac) is only giving out 5 volts AC on the yellow and white and 10volts on either colour and green(earth). So i think its shot. My question is A. does anyone have a generator for this bike? B. do you know of a matching generator from another bike that would be cheeper and easier to get hold of from a breakers? I have asked my local Honda dealer and they are quoting over £70 for it to be rebuilt, or £200 plus for a new part... i would like to find a secondhand replacement for about £30

A) get a copy of motorcycle news look in the parts section for a company called partfinder it a quid for the call tell them what you are looking for leaving your number with them they will then get up to 200 breakers ring you if they have the part then you can sort out with them.also look in used bike guide they always have a list of bikes that people break you may find that part.also a company called dave silver sales cheap bits for honda,s you may be surprised sorry i don,t have there number to hand but do to my knowledge have a web site.also try ebay.good hunting

How I can make electric generator from Honda CD70 engine?

Q) I want to make a electric generator for residnetial use from 70 cc motorbike engine..

A) Sounds like a fun project, but there are some challenges. I suggest buying a new or used generator or getting a scrapped one and rebuilding rather than trying to make your own. But, to give it a shot anyway, check the power output of the engine online. I recall claims the 50 cc put out 5 HP, so the 70cc should be able to do 7. This seems a little high, but maybe not. Look at the power curves for the engine, and determine where on the curve you want to be. Max power is typically at the top end speed, probably 8,000 rpm or so for this engine. You might want to back off quite a bit, because the generator has to be run at the same speed all the time, no matter how much load is on it. Running wide open all the time, the engine won't last long. Get a generator, perhaps from a scrapped unit. Usually, the engines put out about 1 HP for each 500 watts of possible load, so 3500 watts max for yours. OK to use bigger generator than you need, won't hurt anything. Look at the speed of the generator, determine the speed you plan for the engine, and select v-belt pulleys or some type of gears so the generator runs at its normal speed (normally 3600 rpm) when the engine is at your design speed. Now the hard part. You have to figure out a way to keep the generator speed almost exactly at the design speed. Most small generators use lawn-mower type engines rated at 3600 rpms, and have a governor on the engine to do this. Some of the Honda generators use electronic controls to change engine speed as needed, and electronics to make AC with the right specs. Good luck, you've got quite a project ahead of you!

My emergency generator says "Cycle" "50" on the generator. Does that mean it is not for 60 cycle electric?

Q) I inherited an emergency Honda electrical generator.. the generator side is American made and looks very standard to me, but oddly enough, it says "Cycle 50" on the generator. Now, I thought all electric in the US was 60 cycles per sectond. Why in the world does this say 50. Do I have an oddball thing here that is useless, or is this probably just a misprint or a misundestanding on my part. I want to use the generator to run my small well pump in emergency if the electric goes out.

A) As long as you are using it on a motor, assuming that it is 50hz, it should not cause any problems at all, the motor will run at a slightly reduced speed but you will probably not even notice the difference when it comes to the output pressure.
