I need help. I replaced the sleeve with a steel one. I replaced the stock cast piston with a wiseco. I cleaned the powervalves and drained & flushed my coolant. I took my time and put every thing back together. The bike had been apart for I month. I left the cover off the ignition side. I thought maybe some moisture may have gotten in the magneto & rusted it. Whats a simple way to test a spark? I Unthreaded my new spark plug & connected it to the wire. I then kicked it over & no spark on the plug was present. Last Question: I lubed my rod bearing and crank very well & forgot to remove the oil upon reassembly. Could this be the problem?????
