So I have a 929 it was stolen and recovered by the police, once recovered it went into the shop to get fixed where it stayed for about 5 months because the mechaninc couldnt fix it. Come to find out it was a bad ignition and the mechanic fried my ECM. So I replaced them both. The bike started up fine I drove it around the block and then it sat for the night the next morning I came out to start it and it wouldnt start. The plugs were fouled so I replaced them the bike started up fine, it idled a little little low but it started. I ran it for about 15 minutes shut it off and then went to start it again and it wouldnt start I just pulled out the plug and it was fouled again. Any ideas on what could be wrong.
