Scootworks pulley for Vulcan 900 - too heavy?

[tpetty]

Interesting thread. Don't have any intention of using the pulley, though.

I for one, will never put my stock pulley back on. it is alot more enjoyable to ride now. I don't have much noise out of the belt either. about the same as with the stock pulley. I know some may be unhappy with the pulley, but I am well please with it.

Configure your bike to fit you, Like Vmuth says, he spends most of his time between 0-65, really no reason for the higher gearing. The bike is happy without it. I'm happy with the speedo correction and drop in upper highway rpm. I spend the majority of my time between 65 and 90 single. Also I have had no belt noise issues. No one setup can be 100% satisfactory for all people. It's what makes customizing your bike so much fun AND uniquely yours.

Good call on that one. I am looking forward to popping the pulley on and seeing how it feels. If I like it great. If not, I am sure there is someone out there who would love to buy a used scootworks pulley. Isn't that half the fun of riding? Making your bike your own. Ride safe everyone.

About the weight. Here are 2 pictures of the stock and Scootworks on the scale.

well now that solves the weight question dont it

but to those unbelievers:

weight makes a huge impact, ever hear of a gyroscope?

a hard drive while spinning is a good example of one.

Take a hard drive while it is running and tilt it from side to side in your hand, it is hard to do, same thing with a spinning bike tire or hey even a pulley.

Rotating mass is ignored by most people, but i have come to understand it since i went from 31" tires on my truck to 37" tires.

My truck needs more throttle to get going and more brake to stop, the weight made a large difference.

hope this helps

THANK YOU, THANK YOU, THANK YOU!!!!! Most seemed to give the same weights you are proving here, but the few that came up with double the weight differences were concerning me!!! I have wanted the front pulley since they came out and FINALLY have one coming now. I was so excited to finally be getting one, but suddenly there have been threads bashing it...I feel let down now...

I am sorry, I do not believe that the scales are accurate.

the aftermarket pulley is much heavier than three pounds.

I thought my comments on this thing was over but this is not right.

I already returned my pulley so i cannot weigh it.

Cherry Ann when you get yours why don't you weight it if you can so we can see what you get.

If you agree that the stock pulley is 3lbs. 6oz. how can you argue the second measurement?

Hey fljohnboy... you got your hand under that pulley. Pan the camera down... ?

After reading all these posts, I'm wondering if they didn't make a design change?

I can certainly weigh the new one and show the results! I own a small postal scale I can use.
Truthfully, I have a great mechanic locally that I am going to use to change the pulley. That means I will not have both together to compare.

[MrClean]

The above pictured stock pulley's measurement matches the weight of my stock pulley as measured on my digital kitchen scales. The above pictured Scootworks pulley looks like the one I put in my bike. I held them both at the same time and didn't notice any difference then. Maybe they did have a run of the pulleys that were made out of deutronium, but I doubt it.

That's interesting about the weights. I wonder if Scootworks has done a redesign, or has 2 different sources/designs for the pulleys, because there is absolutely no way that my scootworks pulley weighs the same as the stock one. It's definitely around 2x as much.

And as for the love/hate relationship with the pulley, I love mine. The only modification to my bike I like better than the pulley is my Mustang seat. The pulley means I don't ride around town in 5th gear, and I don't try to shift into 6th when I'm on the highway.

This thread is interesting. I also wonder if there was more than one version of the pulley. I don't remember the weight being that much different, but I didn't weigh them. I had my dealer install the pulley, and one of the comments made by the crew that put it on was that they were impressed with it's quality and machining! I would really like to see that 8 pounder and see what the difference is. I really love my pulley and the speedo is within 1mph as checked with GPS. I didn't really have that much problem with engine vibration, but the bike is definately smoother at 70 mph. I have noticed more vibration coming through the suspension from the road than from the engine. Oh well, to each his own.

Aw, man...

This might be a stretch but here goes... Scootworks doesn't make a pulley for the V2K, do they? I just recieved a chromed one from a Limited a couple days ago and that sucker's heavy... I'd say about 8 lbs. or so. There's not a chance they sent the wrong one is there. I mean, if the bolt pattern matches up... ? I've seen crazier things happen.

[ImpactG]

... I checked... they don't make one for the 2K... nevermind.

[vmuth]

In reality these variances are being reported because there is no control of the manufacturing process. If scootworks in making this product, i am sure they do not have the technical measuring devices as do the major founderies the Motorcycle companies are contracting out the parts to. That is why some people notice a larger weight difference than others. Some folks have more belt noise than others because the machining is different from pulley to pulley.

The scale is on a hook on the wall and the pully is hanging free, no hands under the pulley. Pulley is on the bike now so no new picture now.

It's not just the weight... it's the lever moment.
You increased the stress on your drivetrain and braking system by about 20%, as well as raising your effective gear ratio.

Of course they aren't.

They're Berkley fisherman's scales.

Those pulleys are actually about 2 pounds

[fljohnboy]

I think the scales are pretty much accurate. I just sold some handlebars and used the fish scale to determine UPS shipping cost. In the box it was 11 lbs. Took box to UPS store and when they weighed it it was 11 lbs. Of course weighing a fish it'll read about double. ,
