what size is the breather pipe hose?? looking at fitting an oil catch tank but will need more hose so unsure on the size
-
Standard breather piping has a ID of 19mm if memory serves me correct... I knopw alot of catch cans are 15mm and less so you could use reducers etc....
-
if you fit the sakou michi catch can then the outlets on that are 19mm so keeps it to the required oem size
