Dicko:
It sounds like your rpms are pretty close to mine. I also have the Givi wind screen. When I am turning 5000 rpms on level road my indicated speed is right about 61 mpg. When I am turning 5,500 rpms on level road my indicated speed is right about 71 mph. It is interesting, but the ratios are a bit different at lower rpms though. When I am turning 4,500 rpms my indicated speed is about 45 mph, so I guess that is how the J Costa is supposed to work. I was happy to learn that if I keep my rpms at or under 5,000 I can still get better than 52 mpg even with the J Costa and the Givi wind screen.

My RPMs have always been on the high side. I had occasion to compare with another SW locally about 3 years ago. Mine is a 2002, his was 2005 IIRC.

	Mike's	Rick's
MPH	RPM	RPM
65	5500	5000
70	5900	5400
75	6200	5800
80	6700	6200
85	7100	6600

My scoot was faster off the line too, but he would catch up an pass me by 60 mph. Makes me wonder if my my scoot came with lighter rollers?

My RPM dropped about 200-300 when I replaced the drive belt, but after a few thousand miles they were back in the same range.

I'm anxious for Honda_Silver's report on the Dr. Pulley sliders and the HiT clutch. That may be my next mod.

Did the Dr Pulley sliders do anything for the belt noise ?

Excell,

I never really had any belt noise. I don't recall ever getting the "belt slap". I use the Mitsibishi belt from scootertrap.com so maybe that is why. But I don't remember ever hearing it with the stock belt.

It is more of a growl than a slap but when I take the cover off I can see where it has been rubbing on the case . I also have the Scooter trap belt .
I also sanded off the pulley face when I had it apart .I have not tried it since I did all of this since it has been raining .It is supposed to snow tonight .

It sounds like the belt on your car when it gets old and dry .

Mine slaps like a fish out of water ,thinking of maybe changing the rollers or clutch or both would change the belt too but thats new
How easy are these things to change??

After you have done it a time or two it is real easy .After you take the center bolt out ,take off the front face ,then the belt .Now put your fingers behind the rear face and pull off the rest .The rollers and sliders are in between and will roll all over the garage if you don't do it that way . I put an old towel under neat then if stuff falls out it doesn't roll away . If you get it apart together ,set it face down on the bench .Now lift up the face ramp and you will see the rollers and sliders .Take a picture of them to help you remember how they go .I tried to post a link but it failed .If you try this and get into trouble email me and I will try to help you .This stuff seems like nothing to me as I have been a car mechanic for 46 years .

Thank you very much for the advice when i get them i will have a go may be (pollini)cant seem to find the dr pulley sliders here but will keep looking i

Thanks for the web address but they dont seem to have them just pollini rollers did a search within the website a drew a blank ,the search will continue....

Well,

I filled up for the 2nd time with my sliders and avg'd 51 mpg. I was driving somewhat conservative where 1/2 of my riding was interstate doing 70 indicated, and the rest of the time going anywhere from 35-55 mph. So that is good for me. I'm going to experiment with this tank driving more aggressively... so far I have been going about 75-90 indicated, so I will see what I get now.

The fuel economy varies a lot from one bike to another. I got 53 mpg on the first 3 tanks and just scored a 57 on the latest one. Mostly freeway, 70 mph to 80 mph indicated, including a lot of steep, long climbs over a mountain pass.

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.
