I own a 1973 CB100 and run about 50km everyday. I have changed my firing plugs and contact breaker but the running is not very smooth at 70 -80 kph it jerks. I was advised to replace the ignition coil conderser (under the gas tank). Q. can i replace it with a Honda CG125 ingnition coil+condenser? i live in Malaysia (Penang).tk
