Need a quick answer

OK, I received my Hagon shock and was out in the garage getting ready to install it per some instructions I found on our site. Ran into something no one had mentioned so I thought I'd check it out before going further. There is a large hose (Not for the air fill - much larger) that connects to the rubber boot at the bottom of the shock and goes up under the seat and is formed to hang over the frame tube below the seat. Looks like some kind of venting or pressure equalization system for the shock. Anyone know for sure what this is? It's not connected to anything other than the shock. Thanks

Yes, it is an attempt to vent the air within the shock's rubber boot. On earlier Second Gens, there was no remote hose like you have and apparently the pumping motion of the shock boot was sucking in road debris, contributing to an early failure of the oil seal on the shock. Later versions, attempted to fix this by venting through a remotely mounted hose vent. Presumedly, the shock boot pumping action would inhale cleaner air.

OK, so it is what I thought. Thanks Kev ... I appreciate the quick answer. Now, back to the fun.

Curious that your 2000 has the remotely vented shock. Yamaha didn't start that hose thing on the shock until 2005. Is this the second go around for a rear shock on your Venture?

I don't know. I've only had the bike for 3 years, so it's possible a previous owner had it replaced. The nut holding the schrader valve certainly looked like someone had been working on it at some point so it's quite possible. The bike now has 103,000 KM on it (just over 64,000 mi.) so if this is the 2nd shock, it would seem the stock ones do indeed have a short lifespan. Hopefully the Hagon will hold up better...and at least it's rebuildable.
