I have a 2005 Yamaha WR450. My bike has developed the following problem lately. When starting the bike cold using the electric starter, it will not start. If I use the kick starter or roll start it, it starts up quickly. Once the bike is warmed up it starts easily using the electric starter. I figured that if there was some kind of short or voltage drop to the ignition system when using the electric starter that this would be a consistent problem even if the bike is warmed up but electric starter works fine when the bike is warmed up. The battery is new and voltage readings are good. Any ideas? Thanks in advance!
