Just replaced my faulty electronic nosecone ignition & coil. Fixed the problem but now I can't seem to dial in the timing position of the unit. Seems to run OK but notice a pretty loud knocking around the front cylinder and that plug fouls with black carbon deposit within a day or two of riding. rear cylinder plug looks fine. Is this due to the timing not set properly with my new ignition. Ran strong before my old ignition went bad.

please help if you know these symptoms. Thanks!

 

'99 EVO motor.
