hi im new to this site. i got a 95 yamaha wave venture that sat for 4 years. it only has 98 hrs on it. i put new plugs on it, fuel filter and rebuilt carbs. i had it running fine. when i was in the ocean jumping some waves it shut off and would not start back up. when i got home i determined im getting no spark. i put another set of new ngk plugs in. just seeing if anyone has any ideas or test values of the pickup coil or even a service manual. thanks
