I have a 2002 Honda Foreman 450 ES. I recently rebuilt the entire motor putting a new bottom end and top end on it. After rebuilding the bike i started it and it was running fine for a couple minutes. I shut it off because i still had other parts to put back on the bike. The electric shift went out on it so i made a price that welds onto the shift peg and it makes the bike a floor shift. On the old motor i never unhooked the battery just kept my ground close to what i was welding on. After i welded this peice on now i have no spark. There is no power going to the coil.I changed out the stator but that wasn’t my problem. Any help would be awesome thank you.
