My last ride on my 06 450 the oil drain bolt by the shifter fell out. I stopped riding thinking the bolt just fell out and I would order a new one. Got my new magnetic drain bolt from Thumpertalk today and went to put it in and it won't thread. Upon closer examination it seems there is some of the threads in from the old drain bolt. Is there a easy way to get out these threads or do I need to go to the local repair shop? Thanks.
