Heres a pic of my 01 grizzly 600. There seems to be an air duct/hose missing. I had put a piece of steel wool there to prevent anything getting in. Id like to know what piece is missing. How important is having it? Assuming it is important. Would i have to order the exact part or can i get some type replacement tubing/hose from a hardware store? Looks like it probbably connects to cvt belt area. This has had me puzzled. Thx.

That's the CVT Intake. Very important to have that there.
You can do a snorkel type intake with plumbing supplies from a hardware store, or buy the factory plastic piece that belongs there.

Part #: 4WV-15471-00-00

Got to any online Yamaha parts diagrams. Under your specific model, go up "crankcase cover 1", item #21.

Thanks. Im gonna look into snorkel mods probably. Would it be okay to leave that the way it is for now, until i can fix it? Assuming im not doing any crazy mudding or nothing.

That's up to you. Short term riding around the property it won't hurt much. But longer term is a different story. Water and dust will enter easily and cause belt slippage, clutch face wear, grease hardening in the primary, etc...

Im probably not going to need to actually snorkel it. I think im going to look around and craft a substitute w some simlilar hardware piping.

Would making one myself be okay. I just cant afford to order a new one rn and i cant find used one w same year. I figure this would be okay as long as i fixed it to where the oringinal is supposed to be and its out of the way and purpose served. What kind of piping should be used?

Make it up if you like. Nothing wrong with that. Just as long as something is there higher than that.

So i spotted another open duct that i got to figure out where it connects to. Heres a pic. It is the top right of the T shaped duct assembly. I really am grateful for everybodys help on this forum. It has helped so much.

That's normal installation of that duct. It's the belt box exhaust. It is only missing a small back turn that directs air to the cylinder head. It prevents water from being splashed into the pipe by the front tires. Basically a splash shield.

That's the part number of the peice you'll want. I suspect it's no longer available from Yamaha, so either buy used or make it yourself.
