Hola, I'm currently using an Alimax breather unit/catch tank for my engine and was wondering if the unit is suitable. I have just realised that the bore of the catch tank ( I'd where the pipes attach) is slightly smaller than the outlet on the rocker cover and the breather on the block. The catch tank has one of the shitty little sir filters on it approximately 2" in diameter. Do you think that the smaller borecould cause a restriction and should I do away with the filter thing and just have a hole. Cheers
