If it has the oil injection, there should be an oil tank under the left rear fender. The benefits of premixing is that you'll know the engine is getting oil. The oil injection gear can break and the only way you find out is when the engine seizes
Ive never had any problems with mine but alot of people dont trust them, so they take them off. If you take it off you run your own mix, and you dont have to worrie if its gonna brake on ya
the blaster i had the oil injection,its was a 96,and it never broke, i sold the blaster so i odnt know if its still working. But if you wanna go safe take it out.
