[Quick_Shifter]

hey guys, i just striped my crf 50 down to its bare frame to spray and fix head bearings and when i was putting it togeather theres a little house poking out the top on the gearbox next to the top engine mount and have no idea where it goes haha

pretty sure your talking about the crankcase breather hose,

one end is connected to the engine case, and the other end hangs neatly where it cant get squashed shut anywhere, and it just vents out to the atmosphere and pollutes the ozone lol.

you gotta make sure it always stay unblocked, they are known to get squashed between frame parts etc,

yep, pitmaster is right just make sure that no pressure can go back into it, dirt doesn't go into it and it's not squashed or blocked..may cause seals to pop, a good idea is to pop a little air filter from uni onto it, and then mount the tube and filter onto the subframe with zip ties
