thanks teazer ill get with you on tbe phone befor i.do anything i cant reverseteazer said:On a 400 the oil pipes go to a special drilling on the lower front part of the carb just before the reed boot. Piston port motors are drilled at the side of the boss where the intake manifold bolts on. That applies to DS7, R5 and TD3. The oil feed can also go into the float bowl as is done on some Kawasakis or into the reed cage.
Try to avoid having them discharge into still air for example above a dead zone or to teh sides where there's a ribber intake stuffer obscuring them..
