That's excellent gas mileage Mickey. Especially at those speeds. My scoot is an '02 that only had 1365 miles when I bought it in 2005. I averaged 52 mpg when I first got it, but that was mainly country roads and city streets - very little freeway riding at first. Then as I got a little more experience and started riding a little faster, my MPGs dropped a little.

I replaced the belt around 14,000 miles. This was a little early, but my RPMs seemed high suggesting to me that the belt may have been worn, so I replaced it. The RPMs did drop 200-300 RPM at highway speeds. The MPGs improved back to the 51-52 mpg range. Now that I have 26,000 miles on the scoot, the mileage seems to be back in the 48-49 mpg range.

My typical riding is probably 40% in the 50-60 mph range, 40% in the 35-50 mph range, and 10% at freeway speeds. I find that my mileage drops rapidly above 5,000 RPM. I'm really impressed with your gas mileage at freeway speeds. I would probably be in the low 40s at those speeds.

I could probably improve my gas mileage if I would be more gentle on the throttle. I tend to like to accelerate rapidly

Bill:
What did you do to get 56 to 60 mpg? Was it the Power Commander with a special mapping? That is really good mileage.

Bill,

Thanks for the info. That is great mileage and I know I'm getting one now. I should get about the same since I have a Givi, that I cut down about 2", and basically a stock bike now. I will be happy with 55 mpg when I get one. Again thanks for the info.

Bernardo,

I bet your SWing really does get going with what you have done. For my birthday I asked my wife to get me the power commander so I will play with it too then. When I get it I will have the european map installed and then do some tests with the J. Costa and the Dr Pulley's.. I just like to play around with things. I do miss the J. Costa for performance but the mpg's are kind of nice to have too. I guess you can't have it both ways.

If my exhaust ever goes bad I will replace it with a Leo Vince but I don't recall ever hearing of an exhaust going bad. Have you ever raced a stock SWing with yours? I'm curious how it would do.

Jeff:
I don't have the power commander yet, but I have found that if I take it easy on my acceleration and cruise speed (basically keep my rpms below 5,000 - even when taking off) I can get 52 mpg. I am planning on putting a power commander on my bike later this year to see if I can do even better. I was impressed to read what sort of MPGs some people were reporting. It would be pretty nice to get in the high 50's or low 60's, but I won't do it by removing the J Costa. I need the extra scoot going up in the mountains. Will the sliders work with the j Costa? Or do they basically replace it?

Scootist,

The sliders won't work with the J. Costa since they Costa uses pins and not rollers/sliders. I wasn't ever able to be 52 mpg even if I rode very conservative. Maybe it is the ultra-clean fuel calif uses. It seems most of us out here just don't get great gas mileage.

Thanks Jeff. That is basically what I expected, but I thought I would ask to make sure. Interesting, but I would have thought that you guys would be able to get better gas mileage since you are at sea level (or at least a lot closer that I am). We have to use those high oxygenated fuels (10% ethanol) during the winter months and I see a pretty significant drop in miles per gallon when I use those fuels (more like 48 mpg average). The other thing is I try to coast down hill when ever I get a chance and I coast up to stop lights when I see they are red. Maybe that helps.

I just ordered my DP sliders, K&N and 2 new Iridium plugs, can't wait till they arrive!:bounce1:
I have also been working with the laminar lip mod for the wind screen. One other mod was to cut down my spare windscreen to mimic the Clearview sport model. The first test ride was good, I like the extra air. As far as long superslab riding, I think I still like the protection and comfort of the stock screen (and soon laminar lip) combination.

JeffR, You've had the sliders in use for awhile now. How do you feel about them now? Are they better than the stock rollers?

Boatswain,

Yes, I do like them better then the rollers. They are the 28g sliders and I feel they are smoother than the rollers. It seems there is more acceleration up to about 40 or 50, but not a huge difference, but after that it seems the same as the rollers. It also seemed I got a couple of mpg better than the rollers, maybe 2-3 mpg, but then I also have changed my riding habits too, so that may be why. Hope this helps.

I have to believe that the best improvement in in-town fuel economy would be an aftermarket clutch like the HiT or something similar. All that slipping is a waste of power.

Obviously you don't want to get TOO crazy, but Honda has obviously set up the stock clutch to be completely idiot-proof. I'd like the OPTION of being an idiot even if I never choose to do it. I really want the clutch to lock up a lot sooner than stock.

The sliders are a great improvement. Part of the reason that the swing does not cruise well and runs at a high RPM is that the stock roller weights do not enable the belt to ride to the top of the pulley which causes higher RPM's. The 28 gram Dr. Pulley Sliders will cause the belt to ride at the top of the pulley which will result in a 400 RPM drop. I was able to verify this by testing when I was in the process of changing the weights. This is a difference of about 5 MPH. So basically, you can now run 65 at the same RPM that you would have run 60 with the stock weights. This will smoothe the bike out a bit and yield slightly better fuel economy on runs over 55 MPH. I am curious as to whether or not anyone has achieved the same 400 RPM drop with the 23 Gram Dr. Pulley Slider weights.

Ron,

I did not measure my RPM, but I agree on the smoothness. The the lag between 40-50 is eliminated and it is one smooth pull all the way through the throttle. The roller-chatter on take off is also gone. I have noticed a small reduction in RPM but having not measured it I can't be sure. My current MPG's have not been adversely affected, still in the mid to upper 50's (58 last tank). The first tankful after the slider install was affected and dropped to 51-52mpg due to many WOT's ...I mean testing!
I am happy with the results, next experiment is to mix two different weights (28g & 22g) alternating them in the slider slots. A friend did this and reports even better performance

I am thinking about installing the 28Gr rollers and HiT clutch.
I need to send Paul a mail for the final go.

I'm pretty convinced about the sliders but not sure on the HiT clutch.
Those that have experience, can you share your insights?
Isn't the HiT cauing a more 'agressive' touch to the throttle?
Might be that I am mistaken, it just looks like you need to be very careful when going WOT, right?
Any advice is appreciated...

I just ordered a new belt and a set of 20gr sliders so I will be experimenting with the sliders. I have the 28 gr and will install the 20 gr when they come in. I will also keep track of the rpm's too. After I use them for about a week I will use a combination of the 2 to see how they work. I really like the sliders so far but I do miss the J. Costa. Talk about fun with the J. Costa..that is really a good mod.

Hi Jeff; looking forward to your findings!

I know this is an old thread, but it seemed to be the best one to add my experience to...

I replaced my belt, final drive oil, and stock rollers a couple of days ago, at 21,000 miles. I bought the bike used from a dealer, and could tell from the other maintenance I've done, that basically nothing has been taken care of as prescribed. "We inspected the belt, it's fine." Yeah, okay.

Anyway, everything went well, thanks to all the hints, tips, and how-to's provided by the fabulous people on this forum. I installed the Dr. Pulley 24gram sliders. Performance-wise, I'm sure it's better, but I don't really ride the scooter like that. I've recently upgraded from smaller scooters, and the SWing has got plenty of performance for me. My rpm's dropped from 5600 @ 70mph indicated, to 5000 @ 70mph indicated. Like everyone else, my 70 indicated is really 65. It is overall a much smoother ride, much less 'buzzy', which is probably attributed to getting rid of the old dirty, somewhat notched rollers. I haven't run through a full tank yet, but it does appear that I will finally get past the 50mpg hump. My previous best tank has been about 43mpg, so that will be a nice improvement.

So now I've done the Givi AirFlow, oil and filter, air filter, spark plugs, final drive oil, belt, and sliders. Tires are good, and air pressure holds well. Now I can enjoy the ride, knowing that maintenance items are up to date, and indeed somewhat upgraded.

Next up, accessories and cosmetics. I'm gonna have to get together with DennisB and pick up one of his GPS mounts. Maybe more...

Not that far away from ya. 14 mile due South on 75. Your welcome to come by any time...Well, not any time. I'll PM my phone number to ya if ya need it.

Yes sir, I figured I would come on down and pick up whatever I wanted to buy, after confirming of course that you and the parts are available!

Installed 28gm rollers 200mile ago, fuel consumption better and take off much smoother

After I read about Dr pulley.I ordered the 28 gram sliders yesterday and I hope will be to my house today because the store at Oregan.I hope I will enjoy with it.Thanks for all information about this.

I will do report after installation and use it.I run 250 mile at this week end with Goldwing people and they realy supprice how much power my wing have.
