I know that the crankcase breather on the KLX300 has a restrictor stuffed in the hose, but it can be pushed out easily. Why do people sell a kit to replace the factory hose when all you have to do is remove the restictor and re-attach the hose? The only thing I can think of is because you may suck oil thru the carb??? Any thoughts on this subject? I have the restrictor out but haven't re-attached the hose yet until I can reason this thru. Thanks.
