Battery may be old though. She was an older mans' wife's bike and she didn't like riding which is why I got it at a good price for less than 5000 miles. He had changed the tires, oil, belt (just to be safe since she's been a garage queen), spark plugs, rear brakes, and spark plug. He was going to chop it but all he got done was put a short pipe on and boy is she LOUD! Thinking she needs to be rejetted still because she backfires a lot
Odd thing about our ignition module is it WILL NOT PRODUCE A SPARK if the battery isn't fully charged.
Your first step is to FULLY CHARGE THE BATTERY then keep a volt ohm meter on the battery terminals while you crank the bike and tell us what voltage it drops down to.
If it gets below 11 volts when cranking the starter motor -- then you may possibly get zero spark out of the black box to the spark plug to ignite the fuel.
A good battery, well charged, maintains over 12 volts when you hit the starter button, and everything works like it is supposed to.
This low cranking voltage thing has driven a lot of guys nuts over the years .....
