Hello, I recently did some work on my 91 vn750. After putting everything back on the bike I went to start i t and was getting no spark in all cylinders. I checked the IC ignitor and traced the problem back to a loose stator wire. I repaired the problem and then the bike started..... for a few seconds and then cut out. I checked both coils, stator, IC ignitor with an electricla tester and they all were within the listed limits in the clymer manual. I pulled the from spark plugs and still am getting no spark. The rear are working just fine. Any suggestions would be helpful.
