I have a 2008 yamaha raptor 700 bone stock. It started acting up it lately if the lights are on It runs perfect but with them off it spits and sputters like crazy. I replace the rectifier/regulator but still doing the same thing. Any help would be greatly appreciated.

Thanks in advance

 

Odd! I would check with the guys at Raptor 700 Mods - Modded Yamaha Raptor Forums for that answer!
