If there is a oil tank under the rear fender, and the blaster is running fine, I would stick to using the factory Yamaha oil injection system. Its a solid system that works great. The only thing that screws it up is operator error. Just keep oil in the tank. Top it up before, or after you ride. We run it on stock blasters, and ported/piped blasters with zero issues. If your blaster still has the stock oil injection system, Perhaps give it a shot, before just taking it off and throwing it in a box. The oil tank lasts through 3 to four tanks of fuel. I like mine.
