I recently purchased a 2005 bigdog mastiff, when i recieved the bike the starter was bad! I replaced the starter with a new one. about 3 weeks later in which i may have riden it 4 times i was out one afternoon when we made a stop! With my bike off and the key in the off position the bike wanted to jump"as if someone was trying to start it in gear without the clutch in"! then it jumped again I was able to grab it before it fell! so i figured keep it in neutral when its off till i can get home! bike started up fine! Next stop about 100 miles later, we stop for gas gas and something to eat! 30 minutes later we come outside with my key in my pocket i now see my headlight is on. Switches all off and key in my pocket. I try to start the bike and I get nothing at all! tried bypassing the starter will crank but wont turnover! Any ideas?
