McCabe-Thiele (Ted):
I put mine in the Ultra Sound Cleaner - then just made sure they looked clean.

Nurse Julie:
They have no moving parts in them Mike. Give them a good clean out, don't make the holes any bigger though as they restrict flow to the head which gives the oil priority to the crank. Making the hole bigger reduces the priority to the crank.

Mike_Berkshire:
Thanks both, that sounds very straightforward.

Mike_Berkshire:
Another beginner query. I have been trying to get my brain around how the airbox assembly goes together and I think I get it apart from the connection of breather tubes. What I have understood is that: 1) the breather tube from the rocker cover should connect to the horizontal spigot on the bottom of the airbox but can actually vent direct to the air passing it between the carbs and dangling it behind the swingarm pivot; it only vented into the box to comply with US emissions regs. 2) there should be a drain pipe from the plenum which vents to the air but it should have a pinch valve at the end - a sports drinking valve (Camelbak) can be bonded on the end to make this as the original one is no longer available 3) the drain from the bottom of the airbox can vent to the air along with the other 2 but needs something like open cell foam in the output end to prevent crud ingress. Is this right and if so should I plug the now unused spigot in the airbox?

Any thoughts, corrections or general ridicule at my interpretation welcomed. Cheers, Mike

DomP:
I recommend using the parts diagrams on CMSNL, great fir things like assembling airboxes etc
