Hi all,

I have the same 1" pipe from the primary and it runs along the chain guard,
then heads up over mudgaurd (fender) at the frame diagonal then all the way over to number plate.
The smaller breather from top tube runs under tank and drops down inside the battery box bit
where it joins the main breather (with tee) which is just above the front chain guard bolt.
There is also small hole in the motor just above drive chain,
this was for a chain lubricator pipe, which is another tee from the main 1" pipe just above it.
I do not have this bit connected.
