I have a 2002 Legend 700 that won't start. Using electric start, we hear a grinding noise from near the battery. I replaced the relays one at a time to no avail. The battery shows full charge and we even tried using a jump pack. The started does spin, but not fast enough to throw out the gear to engage. When I pull start, I get a good fat blue spark, but can't seem to get it started. Usually for the first start I have to crank this think on electric start for 30 or so seconds anyway, so maybe I just didn't pull it enough. Any thoughts?
