worse.the Harley motors aren't externally balanced but are somewhat mechanically balanced.I don't know how to explain it on a keyboard,persay, but I'll try.it has to do with rotational mass and laws of motion and gravity.the weight of all the parts on the Harley all have a better rotational mass than the Vulcan parts,hence the need for balancers.

There's quite a few bushings on ebay, but they are $10-12 each, plus shipping, and you have to search around to find the two magic ribbed ones.

Saw one listing with the same 92075-1748 part number, but the ad said it was for a Vulcan 800, so maybe they crossover.

Well, $4.22 + $4.88 shipping in a couple of listings.

So if Delrin scares people, how about steel?

The round 1747 damper is unique to the VN750 and does not crossover.

The cog shaped 1748 damper is used in our engines and the 95-06 Vulcan 800 Classic

I'm not syaing the Delrin scares me, rather pointing out I suspect people will be hesitant to use them over the OEM ones without descent mileage data and feedback from a member willing to brave the untested dampers.

That's why I listed the 1748 part number.

Have you ever held a set of dampers in your hand? They are nothing special, kinda sh!tty actually. I think Delrin is a few steps up.

My dampers are new and I don't see me riding enough to wear them out out. But if I needed a set this week, I could have some made, with Delrin, brass, steel, inconel .....

Give Kawi enough time to drag their feet, somebody, somewhere, will be making them, even if they only make one set. The 750 is already 10 years out of the last production date, Kawi has no legal obligations to this model at all. What do you think the beancounters will say?

I think the best recourse right now is for Everyone who has a Vulcan that has not replaced their dampeners to go to your local Kawasaki dealer and order a set.
Perhaps if they see a large increase in demand they might be more obliged to fill it.

As far as running the bike without them....I again counter with the fact I did say it might have been "a stupid question" , but will also point out that no one has done it .....so we really do not know for sure how badly the bike would vibrate. If in the future Kawasaki ceases making this part, and no one steps up to do so, it will either be this or the death of the model.

I think this is a good idea. I don't think were in any danger of Kawasaki making the part obsolete and discontinuing it any time soon, rather the hope / goal is to get them to produce MORE per batch and go back to maintaining a positive inventory of the dampers vs the new standard of order and wait months to get a set. The dampers are a wear and tear parts like engine rings or clutch discs so going "used" (a good option for many parts) is really not a option.

I have a glass half full attitude regarding the notion that without Kawasaki producing the dampers, our VN750's will die out. Necessity is the mother of all inventions and I'm fully confident someone among us would discover or manufacture replacement dampers if that was the only option. I have a 1983 Honda CX650 Custom sitting in my garage. The bike / engine was only made in the United States for ONE year. Most of it's parts have been discontinued by Honda for 10+ years and guys have come up with numerous ingenious ways of keeping their CX650C's on the road. For example, engine rings have not been made for over a decade and given the age / mileage of these bikes is a frequently needed part. So one member of the CX650 community (vastly smaller than our own) took a used engine ring to work with him at Autozone and went through box after box of engine rings until he found engine rings for a Hyundai Elantra that with a very simple mod work perfectly in the CX650's engine. No matter what Kawasaki does, we will find a answer to keep our bikes moving down the road...

Sorry to cause all this obsurdity in the community. I made about 20 different phone calls to all the venders I could and no one would supply the part from inventory. All back order. This is my daily driver so I didn't have time to wait for new. I put a good used set in and hope for the best. I do have 2 sets on back order just for the futures sake.

I guess the price has just naturally gone up in three years. It was $40-45 for a set, now roughly $60-65.
