Whay exactly did you do to modify your snorkel?

dfaz · Veteran Member

I cut two sections off the external and two secttions off the internal which did improve breathing,then added a kand n filter these two mods made a big difference but it did run a bit lean,(we are at sea level)see pics

Cheers, I get you now. The pictures explain it nicely. Very bling K&N!

if you went through water and stuff that is nothing. theres only a little run off in there. I put a bead of silicone around the hole where the snorkel was ripped out of mine to act as a barrier for any run off. had nothing in there yet. actually ive had nothing in the area and been doing heaps of puddles and stuff lately

where do the two breather hoses above the snorkel in the first pic lead to? the ones that arent secured in your picture

dfaz · Veteran Member

thats where they terminate from the carbouretor ,they were loose after refitting the airbox hadn't finished before I took the pic

davecambo · Senior Member

but what are they. does anythin come out of there?

dfaz · Veteran Member

they have non return valves on them cant remember what they do exactly but nothing should come out of them.Brian may shed some light on that one.

davecambo · Senior Member

yeah just thinking cause i ripped my snorkel out and they finish right next to the hole where the snorkel was. if something does come out of them its going in that hole lol.

i could just re route them easily enough.

They are breather tubes - one each side of the carb where there is a T joint. The lower pipes have one-way valves to allow the tubes to drain but not allow water back up.

Seems like mine have suffered mods or damage. One NRV missing.You wouldn't happen to have a picture or diagram of where the right hand hose fits?

I've got the left one on but I suspect the other one has been adrift since I got the bike!
