Try flipping your ignition switch back and forth also if you have a run stop switch there may be just some carbon or oxidation prevent a good contact.

Get on the web and GOOGLE " motorcycle salvage honda ".
If you can't find the CDI unit there you won't find it.
Please rate this solution. Thanks!

The CB250 RS unit should be similar. The FT500 lump was actually derived from the XR/XL500 dirt bikes, so if you can find one of those, that may help. There was also a U.S. version of the FT500 called the Ascot, so you might try checking out U.S. websites.

Hey whats up? Try back probing your wires going to the CDI unit with a volt meter or continuity tester to make sure you do have any broken wires. Then check the stater make it is good. If sure how to check the starter take it a bike repair shop they should check it for free.. If that does work let me know and I will look further into it for you. Good Luck.

SOURCE: No spark
Check the side stand kill switch if your bike has one. It kills the engine so that you don’t start out with the side stand down. If broken or out of adjustment, it would kill the spark. Check for a broken wire at the side stand switch and coupler. Try moving the kill switch by hand. If that doesn’t work then wire a jumper around the switch to bypass it. Check the fuses. How good is the battery? Try a jump start from your car battery. Is the handlebar kill switch on? Check the operation of the ignition switch and all kill switches with a volt ohmmeter. Install new spark plug.
If that doesn't do it, check the wiring harness. Did a wire come unplugged? Are all wires clean and with solid connections? Any abraded or pinched wires? Is the bike in neutral and the neutral light is lit up? If no neutral light, check the neutral switch and neutral switch wire on center casing. If still no spark, get CDI system and coils checked at the dealers shop. You can screw up a CDI unit checking it yourself.

I have a 83 DR 250 and i'm not getting enough voltage to create a spark, all I can suggest is that you check your battery and make sure its at full flavour. Check and see if you are getting any voltage prior to the ignition coil (should be 18-35v). If you suspect battery then try clutching it as the alternator moving faster might give you enough to get her going. Also check all your connections and earths. Earth wires are often overlooked and can cause you just as many problems as the actives. So give that a go and get back to me mate. Cheers
