what is this hose?

91satanslegend · November 4th, 2011, 08:42 AM

What is this hose coming from the carb and is it important, because i took mine apart and did not see this hose....so im trying to figure out what this is and if its something i need before running the bike...

I'm not sure what you mean by not seeing this hose... you mean you didn't notice if it was connected to anything? It's been a while since I've dug around by carburetors, but I'm fairly certain that's a vent hose, meaning it doesn't connect to anything at the other end

A helpful way to check is to look for a clamp on the other end. if there is one, it defnitely connects to something. if not, it's probably a vent hose.

ok if its just a vent hose, do i need one? or will i be fine without it?

you'll want some length of hose there if it was there before; enough to direct it a bit away from the engine would be my guess. I have a new gen, but on mine the various vent hoses all run back and down to about where the rear shock is.

I believe that's a vaccuum hose, or snorkel, as I've heard it referred to as. I may be wrong there. Those two may not be the same thing. But I've heard of people removing their snorkel with no ill effects. Mine is still connected, haven't played with it since re-jetting. But maybe someone can pipe up with absolute correct info on that.

its an overflow hose that comes from the carb bowls . if the float gets stuck the overflow of gas runs out the tube to the bottom of the bike. no "technically" its not needed BUT i would rather have any gas run out under my bike than all over it waiting for a spark. some might argue that without the tube attached an negative presure can occure where the tube attaches and can cause gas to get sucked out. (don't know how true that is but i have heard of stranger things).

The snorkel is the rubber rectangular tube that forms the air intake section of the airbox. It's unrelated.

well i had to take the carbs back out anyways because they are still leaking...UGHHH, and i might as well go by ace hardware and fit some tube to the overflow...

91satanslegend · November 4th, 2011, 10:30 AM

btw, my carbs leaking, its coming from one of the screws under the carb, nearest the idle knob. could this be a broken seal???

GateKeeper · November 4th, 2011, 10:47 AM

broken seal, or a loose screw

before you put the new seal in, were the faces cleaned, no old seal materialwas left, any little bit could cause a leak

careful on tightening the screws, do each one a little bit, and if you can tighten in a criss cross pattern, snug em down, then apply more torque

91satanslegend · November 4th, 2011, 10:58 AM

um... im going to go take em apart now, im pretty sure i tightened all the screws and the seals were clean..but they are probably old.
